Executive Summary: 

Problem Statement: 

Since the late 1980s, The National Institute of Justice (NIJ) and Law Enforcement Agencies 

(LEAs) worldwide have been seeking a solution to better manage police pursuit outcomes. 

StarChase has developed a tagging and tracking technology that allows law enforcement to 

deploy a GPS tag onto a fleeing vehicle. This allows the pursuing vehicle to fall back and drive a 

slower, safer tactical interdiction. 

The launcher contains two GPS tags and is installed into the grill of the police vehicle with 

the interior control panel and/or remote key fob providing deployment capabilities. When the 

officer deploys the GPS tag on the fleeing vehicle, the tag begins to transmit location based updates 

in “real-time” which is every 2-5 seconds. 

Available Data: 

Pursuits are a widely known liability for LEAs and the statistics surrounding them are often 

discussed. Here are the most relevant facts: 

1. 55,000+ injuries per year (Lewinski, 2013) 

2. 360+ officer and civilian fatalities per year (pursuitsafety.org: NHTSA FARS data) 

3. $1.3+ Billion in jury-awarded damages (AELE Law Library, Case Summaries 1988-2007) 

The following is a snapshot of pursuit settlements summarized from recent years:

The settlements and research references above are based upon limited information available 

to the industry. There is no mandatory pursuit reporting system for law enforcement and as a result, 

the data is extrapolated from multiple disparate sources. For instance, the fatalities referenced from

the Fatality Analysis Reporting System (FARs) report only report on state and federal highway 

fatalities. Sources, such as PursuitSAFETY, indicate fatalities are two to three times higher when 

considering local and municipal road ways. 

The monetary estimate is also dramatically low as it does not include out-of-court 

settlements, LEA health care costs, related agency property damages and overall lost productivity to 

all involved. The supporting listed settlements totaling nearly $70 million are a small fraction of 

sourced awards that were a newsworthy headline or article. It is worth noting that Chicago is largely 

identified because they are one of the few cities that post litigation and subsequent settlements. 

Seven years (2007-20012) of data identify nearly $50 million in pursuit related settlements and this is 

only in Chicago. 

Despite the fractured data, the need for a better alternative to the traditional police pursuit 

is obvious as news headlines continue to reflect tragic outcomes on a daily basis. StarChase solicited

the award based upon successful beta trials and the following summarizes the research goals of the 

cooperative agreement. 

Research Goals: 

 StarChase received this award in FY 2011 and an initial part of its implementation was a 

meeting with our program manager, the Pennsylvania State Center of Excellence Associate Director, 

and the Pursuit Management Technical Working Group. During the meeting we informed those

gathered that much of the generation II (SC GEN II) technology development was nearly complete. 

Field trials and several technology improvements, where officer feedback would be invaluable, were 

a next stage goal for fielding the product and establishing the system as a valued pursuit 

management tool for the law enforcement community. As a result of this meeting we focused on 

the following goals in the Statement of Work. 

1. Establish four test beds with 10 units per test bed in a variety of agencies (urban/rural) and 

environmental conditions (desert/rain) to evaluate the system’s performance capabilities. 

The goal of the test beds was to evaluate criteria as mutually determined by the customer, 

technology provider and NIJ. Targeted outcomes included an evaluation of system 

capabilities, user friendliness and to collect data on real-world tagging case studies and 

summarize the outcomes. 

2. The engineering improvements were established based upon the current SC GEN II pursuit 

management system with suggestions from our LEAs for customer improvement: 

a. Integrate an on-board compressor into the SC GEN II system in order to reduce the 

operational costs of the system and to ensure a stable PSI to deploy the projectile 

consistently when tagging a fleeing or high-risk vehicle. 

b. Explore adhesive alternatives for a broader range of environmental conditions. The 

existing adhesive was limited when temperature dropped below 320 F and also 

showed less than optimal performance in wet environments. Improvements in this 

area will allow the system to be used in a broader range of geographic areas. 

c. Explore targeting and range finding capabilities to measure distance to target/vehicle. 

This approach provides an officer both visual and audible confirmation when in range 

of the target vehicle.

Background and Research Results: 

The research was designed to provide user feedback on the system’s performance and the 

engineering improvements explored under the goals of the cooperative agreement. The agreement 

also sought to gather user case study details of tagging events in the field to determine if the system 

reduces the risks and liabilities associated with high-speed pursuits. 

StarChase and the NIJ worked collaboratively with Dr. Geoff Alpert in order to develop the 

research methodology and protocols for the field trials. This technical report includes a proposed 

Research in Brief (RIB) that summarizes our test bed results (see attached Appendix 1:StarChase/NIJ 

Report Proposed RIB). Dr. Alpert has been involved in pursuit research for more than 20 years. He is 

a prior chair and current professor for the University of South Carolina’s Criminology Dept. Dr. 

Alpert’s past research includes interviews with incarcerated individuals involved in past police 

pursuits. The interviews provided data collected from three different correctional facilities. “One of

the more interesting findings from the suspects concerned their willingness to slow down when the 

police stopped chasing them. Approximately 75% reported that they would slow down when they 

felt safe. They explained that on average, they would have to be free from the police show of 

authority by emergency lights or siren for approximately two blocks in town and 2.5 miles on the 

freeway” (Schultz, Hudak & Alpert, FBI Law Enforcement Bulletin, 2010). Alpert’s data from this 

agreement has generated positive leading indicators to support this prior research. The case study 

examples included in the proposed RIB indicate the following: 

• On average, a tagged suspect slows to within 10 miles of the posted speed limit in 

less than two minutes. 

• Case study examples experienced no injuries, no fatalities and no property damage. 

• An 80+% apprehension rate.

The engineering goals also allowed StarChase to test technology improvements in the field 

and gain agency feedback. 

The first system improvement involved the ability to integrate an on-board air compressor. 

The integration of the on-board air compressor was the least complicated of the explored system 

improvements. The compressor is now separated from the launch system and this allows for a 

smaller footprint for the launcher unit in the grill of the vehicle. It allows the launcher to deploy a 

GPS tag at a stable PSI without the ongoing maintenance and expense of using a compressed air 

canister which was previously used. StarChase selected a commercial of the shelf (COTS) air 

compressor which met all of the governmental and environmental specifications necessary for 

vehicle installation. After passing the bench testing in the laboratory, and trialing the unit in our test 

vehicle, the compressor was installed on all units at our first two test bed locations. The agencies 

gave immediate positive feedback of preference for this approach versus maintaining the system 

with replacement canisters. This air compressor is now part of our standard product. 

Our engineering challenge increased as we began working on the improved performance of 

our adhesive in a wider range of environmental conditions. We worked with a variety of other 

consultants/vendors, and gave them the criteria for improved performance. The vendor’s insights 

were incorporated in order to improve adhesion for off-angle tags by increasing the tag’s time-ontarget at impact and by improving flight characteristics. StarChase was able to successfully reduce 

the density of the nose cone to increase time-on-target.

Page 8 of 43

The subsequent adhesive research led to identifying a new proprietary adhesive, which 

allows for successful deployment at dew-point and its technical specifications allow for deployment 

at 80 F, below our current cold weather temperature limits. The solution produced additional 

benefits by lowering the temperature required for successful adhesion. This allows for an in-thebarrel, ambient temperature reduction of over 300, and lowers the temperature required for the 

projectile’s successful adhesion. For the agencies using the system, this equated to improved shelf 

life and faster system arm time. 

At present, StarChase and our adhesive consultants agree; in a true wet environment 

(rain/snow) there is still a hydroplane effect occurring on the target at time of impact. We plan to 

continue exploring design alternatives. The improved adhesive and nosecone have been deployed 

to all of our customers. 

The final engineering goals focused on an officer’s ability to know when they are within 

range of a target prior to deploying a GPS tag ensuring ease of use during deployment. The goal was 

to provide the officer both a visible and an audible signal when they are in range of the suspect 

vehicle. 

We explored multiple technologies to measure distance to target including infrared optic 

(IR), laser reticle, sonic and radar. The technologies evaluated each had specific benefits but the cost 

of the improvement was a primary concern as we evaluated the overall cost to the system. The IR 

optic and the sonic commercially available solutions were low cost but unfortunately failed at the 

bench test. The radar option was very expensive (with an $800 to $1,200 expense added to the 

system cost before expenses for design integration even began).

The solid state laser dynamic range detection (SSL DRD) passed our bench test and was 

integrated into our test vehicle; the system provided an audible tone when in range. This method 

prevents an officer from deploying a tag when out-of-range. The tone helps officers know when 

they are in or out of target range. StarChase elected to move forward with the SSL for in-vehicle 

testing. Today, the distance/range detection module uses a COTS based SSL. The laser module is 

successfully installed in a portion of vehicles in Arizona with the remaining vehicles acting as a 

control group. We are gathering data to determine if the distance to target solution improves 

performance. The performance evaluation will include officer feedback on ease of use; we will then 

determine if the increase in price provides enough added-value to the law enforcement community. 

Dissemination: 

StarChase has shared the data generated during the cooperative agreement with the NIJ and 

we will continue to share/publish this information with the following key audiences: the general 

public; the National Institute of Justice; law enforcement agencies represented at the local , state 

and federal levels; stakeholder organizations with both political and key NGO affiliations such as the

insurance industry and advocacy groups such as PursuitSAFETY, MADD; and other key interested 

technologists within the Department of Defense and law enforcement space. 

StarChase’s website (starchase.com) features a News page which shares current news 

reports highlighting pursuit related information and media, company announcements and media 

coverage of our solution.

The proposed Research in Brief (RIB), will be released to all law enforcement community 

trade magazines and related organizations. The proposed RIB will be presented during the upcoming 

International Association of Chiefs of Police (IACP) conference in October 2014 at the NIJ Saturday 

track session. 

We will also disseminate to law enforcement periodicals and media outlets such as the FBI 

Law Enforcement Bulletin, NLECTC’s Tech Beat, The Police Executive Research Forum, the 

International Association of Chiefs of Police, the National Sheriff’s Association, the National 

Organization of Black Law Enforcement Executives, The Fraternal Order of Police, Commission on 

Accreditation for Law Enforcement Agencies and any related programs such as COPs and BJA. 

We have received past positive news coverage in the past from USA Today, Popular 

Mechanics, Popular Science, Jane’s, WIRED Magazine and many other relevant news outlets such as 

ABC World News, CBS This Morning and FOX News. We are also reaching out to traditional law 

enforcement market publications such as Police One and Officer.com. 

The evidence of safe outcomes revealed in our case studies creates an opportunity for 

legislators to have a positive national impact on citizen safety with a tool that makes a difference for 

law enforcement officers serving our communities. We are actively working with our government

representatives to support initiatives that allow LEAs to trial the technology with the support of 

grant funding including the Justice Assistance Grant (JAG), Community Oriented Policing Services 

(COPS) and Governor’s Highway Safety Association grants with funding provided by NHTSA. 

The dissemination strategy is a critical part of the program conclusion as agencies are 

actively seeking additional grant funding in order to adopt the technology. We are working 

collaboratively with LEAs and public risk pools/to demonstrate cost/benefit analysis to specifically 

address the reduction in risk and related liabilities when StarChase is part of a police force’s toolbox. 

This technical report summarizes the results of our cooperative agreement. The NIJ has been 

studying police pursuit outcomes since the late 1980s and has been seeking a solution to this 

ongoing problem. We are pleased that the preliminary research data indicates StarChase is a “game 

changing technology” that is making a tactical difference in the ongoing management of police 

pursuits, reducing agency risk and improving community safety.

I. Introduction: 

Problem Statement: 

The National Institute of Justice (NIJ) and Law Enforcement Agencies (LEAs) worldwide have 

been seeking a solution to better manage pursuit outcomes since the late 1980s. 

StarChase has developed a tagging and tracking technology solution that allows law 

enforcement to deploy a GPS tag onto a fleeing vehicle. This allows the pursuing vehicle to fall back 

and develop safer tactical intervention methods. 

The launcher contains two GPS tags and is installed into the grill of the police vehicle with 

the interior control panel and/or remote key fob providing deployment capabilities. When the 

officer deploys the GPS tag on the fleeing vehicle, the tag begins to transmit location based updates 

in “real-time” which is every 2-5 seconds. 

Available Data: 

Pursuits are a widely known liability for LEAs and the statistics surrounding them are often 

discussed. Here are the most relevant facts: 

4. 55,000+ injuries per year (Lewinski, 2013) 

5. 360+ officer and civilian fatalities per year (pursuitsafety.org: NHTSA FARS data) 

6. $1.3+ Billion in jury-awarded damages (AELE Law Library, Case Summaries 1988-2007)

Despite the fractured data, the need for a better alternative to the traditional police pursuit 

is obvious as news headlines continue to reflect tragic outcomes on a daily basis. StarChase solicited

the award based upon successful beta trials and the following summarizes the research goals of the 

cooperative agreement. 

Research Goals: 

In order to further validate the technology and improve the system’s capabilities the 

company entered into a cooperative agreement with the NIJ to: 

1. Engineer/develop additional system improvements into our Generation II 

operating platform based upon officer/institutional feedback and design 

modifications that are beneficial to the user with regard to functionality and cost. 

2. Implement four key test beds with 10 units per test bed to reflect varying agency 

structures and environmental conditions. The goal of the research is to gain user 

feedback on the system’s capabilities in a variety of scenarios. 

Research Rationale: 

The research is intended to provide user feedback on the system’s performance with the 

engineering improvements explored under the goals of the cooperative agreement and to gather

risks and liabilities associated with high-speed pursuits. 

II Methods and Results: 

II.A Methodology: 

StarChase Pursuit Management Technology (SC GEN II) was the initial platform for the 

proposed additional improvements. SC GEN II met law enforcement’s criteria for use in the field. 

(See Appendix 2 for summary of SC GEN II platform.)

The research and development goals are intended to determine which improvements would 

be fielded by law enforcement while balancing user friendliness and cost of improvements on a per 

unit basis. 

SC GEN II was established and operational prior to the cooperative agreement and was the 

basic model for the proposed test beds, engineering improvements and furthering of the adhesive 

performance.

Our program methodology encompassed both research in the field and development in the 

laboratory. We used multiple evaluation tools to allow rigorous testing and data collection under 

each stated goal category. 

In collaboration with our NIJ program manager, Joseph Cecconi (succeeded by Brian 

Montgomery) and Dr. Geoff Alpert, the research protocols and design methods were established for 

data collection. Dr. Alpert worked with LEAs, StarChase and the NIJ to implement the data collection 

process in the field. 

Our technical development in the laboratory included initial evaluation and design modeling 

via PRO-E software in order to design and/or select prototypes as well as best ‘commercial off-theshelf’ (COTS)component candidates. Once the prototype was developed, or COTS part selected, it

was first brought into the laboratory environment for integration and bench testing with our SC GEN 

II launcher and projectiles. Based upon laboratory results the prototype, or COTS selection, would 

then be installed in our test vehicle. After testing in real-world environments, StarChase would then 

manufacture additional ‘limited rate initial production’ (LRIP) models or purchase 1-10 COTS units 

for fielding and trialing at the test bed level. The engineering results were disseminated via the test 

beds and/or directly to NIJ in our progress reports. The following is specific to each of the program 

goals:

II.B Methodology , Results and Conclusion for Goal #1: 

Goal : Set up four test beds with police agencies of varying structure, with 10 launch systems per test 

bed to profile pursuit-related risk reduction officer/user behavior and feedback. 

Methodology: 

The research methodology for goal one required a multi-stage process that included 

reviewing and analyzing the official records of the agencies involved and talking with both the 

officers involved in pursuits using StarChase technology and those who were impacted by its use, 

but did not use the technology first-hand. 

The research protocol required several necessary steps: 

1. The test bed agencies using StarChase provided their pursuit policies and training 

documents for review by the research team. These documents set the basis for analysis 

of the official documentation being created for the officer surveys and interviews. 

2. Brief discussions with the assigned point of contact for each agency took place after the 

documentation was received and reviewed. The discussions helped determine the 

specific methodology and timing for site visits and data collection. 

3. While slight differences occurred among the agencies, the data collection procedures all 

followed a similar pattern:

Page 17 of 43

a. Discussions with the agency’s assigned point of contact concerning the history of 

pursuits in the agency and any perceived concerns by command staff, and request for 

pertinent documentation. 

b. Review of documentation by research team, including policies, training materials, 

completed pursuit review forms and accountability documentation. 

c. Initial Site Visit Protocol 

i. Interviews with policy maker(s) and points of contact. 

ii. Survey of officers who have been involved in pursuits 

iii. Interviews with officers who have used StarChase Pursuit technology. 

iv. Review of post-incident data from StarChase.us, the secure map-based 

tracking site. Officers are instructed to attach the mapping information to the 

questionnaire they completed. 

4. Compilation and Analysis of Data. 

 

Phase One: Pursuit Management Technology without improvements. 

Phase Two: Pursuit Management Technology with mid-test improvements. 

5. Checking findings and review case studies with the agency point of contact. 

6. Write Report. 

7. Present results to individual participating agencies. 

8. Final Report Writing and submission of Report to NIJ. 

As a final step, StarChase worked with the NIJ and Dr. Alpert to produce a list of research 

questions. The questions were answered by the officers via Survey Monkey, an internet site for 

fielding surveys, polls and questionnaires. (See attached Appendix #3 for Methodology and 

Questionnaire). This methodology was the basic procedure followed for each of the test beds. The 

results below discuss some of the challenges faced by StarChase in successfully establishing the 

system and collecting data.

Page 18 of 43

Test bed results: 

Some of the largest hurdles StarChase faced with the test beds included the time estimated to 

establish the test beds, on-going training and subsequent data collection. 

The agencies considering the program had to evaluate program participation, develop protocol 

for the installation and use of the system, and then incorporate installation and officer training into 

their operating procedures and schedule. This process took much longer than StarChase anticipated 

and required us to extend the data collection of GPS tags (Appendix #1) to the end of 2013. 

The time to train was also challenging and when the vehicle was subject to a rotating pool of 

officers versus assigned to a specific officer, it required an additional time investment from both 

StarChase and the agency to train all users. Training key patrol and dispatch officers is a critical 

component of effectively using the system. StarChase hired a full-time driver/trainer in January 

2013. This addition to our team has improved our relationships with the agencies and enhanced the 

amount and quality of the data the agencies were willing to share with StarChase. 

In the early stages of the program, it was challenging to collect data post pursuit. There are a 

myriad of reasons for this challenge including geographic distance, building a relationship with the 

officers and just allowing for an officer’s very busy schedule. The combined commitment to further 

this technology, from the agencies, our researcher, and StarChase, led to the proposed Research in 

Brief. 

We determined the need for a control group was minimal due to statistics available from pursuit 

data sources such as the IACP pursuit database and the NHTSA’s Fatality Analysis Reporting System 
STARCHASE, LLC 

515 Central Drive, Suite 101♦Virginia Beach, VA 23454♦Phone: 757-747-9369 ♦ Fax: 757-644-4037♦starchase.com 

Page 19 of 43

(FARS.) This aspect of the data collection was deemed unnecessary and cancelled after discussions 

with our currently assigned program manager, Brian Montgomery. 

 We also learned to prequalify an agency in order to ensure a pre-established protocol for 

pursuit management which integrated StarChase (See Appendix #4 for an example of pursuit policy 

integrating StarChase. NOTE: This is labeled not for public distribution). 

 Using SurveyMonkey to gather the related data has also been challenging. Although two of 

the agencies have submitted their information, using SurveyMonkey, the process for receiving data 

from the agency has evolved in order to better accommodate the agency’s busy schedule. StarChase 

often receives a great deal of detailed information directly from the agency. Even with the improved 

reporting, the RIB indicates StarChase only knows of deployments approximately 60% of the time. 

StarChase pulls reports at the time of pursuit from the tracking database in order to accurately 

track the most relevant facts: date, time, duration of the pursuit, time to return within 10 miles of 

the posted speed limit, arrests, accidents and injuries (or other related liabilities) and general 

description of the event. Unlike the majority of pursuit statistics, we do not rely on the officer’s 

memory to gather measurable data. When a tag is deployed to a suspect vehicle the data generated 

by the GPS tag is loaded to a secure server for analysis. (See Appendix 5 for sample screen shot and 

tracking report). 

Status: 

StarChase has test beds established with four agencies and each site has 10 launch systems 

installed into police vehicles. In addition, a large southwest agency is participating in the data 

collection process with seven systems. We are currently installed with four agencies: two urban, one 

semi-rural along with a border agency. 
STARCHASE, LLC 

515 Central Drive, Suite 101♦Virginia Beach, VA 23454♦Phone: 757-747-9369 ♦ Fax: 757-644-4037♦starchase.com 

Page 20 of 43

The following summarizes the status of each test-bed location: 

1. Southwest Border: Installed in August, 2011 and full trained/operational as of October, 

2011. StarChase determined that the units were not driven frequently enough and the 

location was less than desirable for deployment opportunities. There is a pending request to 

move the units to a location where the units will be exposed to more tagging opportunities 

based upon the number of pursuits and drug interdictions. 

2. West Coast Desert (semi-rural): Installed in January, 2012 and fully trained as of April 2012. 

The agency continues to be cooperative and enthusiastic. However, they were concerned 

that the urban placement of the launch systems restricted use and moved all of the units to 

the to a high desert location which more frequently experiences pursuits, drug interdictions, 

human smuggling and stolen vehicles. StarChase reinstalled these units in April of 2013 and 

again trained all users. We have since returned for additional training and software updates. 

3. East Coast Urban: Installed on June 24, 2012 with and full trained October 2012. The 

deployment and training went smoothly but because of the scheduling and rotation of the 

officers/users, it is difficult to keep officers using the system trained due to the number of 

users. StarChase provided additional training to support the new users so that the officers 

rotating through know how to use the system. The tag event(s) associated with this agency 

are part of the database and included in Dr. Alpert’s RIB which is pending publication in Q3 

2013. Ultimately, this agency discontinued the test beds and units were uninstalled by 

StarChase in late Q4 2013. 

4. Southwest Urban: Police Department is the fourth test bed and was installed at the end of 

Q1 2013 with training completed early Q2 2013. After working with the agency to complete 

additional training, they have begun to use the system with regularity and their frequent tags 

are part of the RIB. The agency submitted, but was turned down, for a second grant from NIJ 

in order to measure training requirements for the deployment of 60 units. The 60 unit 

deployment is the agency’s suggested deployment rate in order to significantly reduce the 

pursuit management risks to the agency. They agency continues to seek funds for additional 

deployments. 

5. Southwest (semi-rural) State Agency is contributing data to the program as well. They report 

use of the system on a regular basis and have recovered millions in drugs and stolen vehicles. 

(See Appendices #6A and #6B: The appendix details case study examples).

Page 21 of 43

Research Summary: 

The 36 case studies submitted, combined with Dr. Alpert’s onsite interviews, are positive 

leading indicators which support this research. Our case study examples included in the RIB 

indicate the following: 

• On average, tagged suspect slows to within 10 miles of the posted speed limit in 

under two minutes 

• Case study examples experienced no injuries, no fatalities and no property damage. 

• Data indicates a +80+% apprehension rate. 

The data indicates use of the StarChase system is making a tactical difference by improving officer 

safety, reducing liability and increasing community safety. 

II.C Methodology, Results and Conclusion for Goal #2: 

Goal: Explore adhesive alternatives for use in a wider range of environmental conditions. 

Methodology: 

 StarChase explored a variety of Pressure Sensitive Adhesives (PSA) and modifications to our 

nosecone configuration to improve our GPS projectile. 

 Prior to the launch of the cooperative agreement/award StarChase was using a 3M adhesive 

formula. We were meeting with success in the field however, in extreme climates, such as those 

experienced in the southwest region, there were intermittent unexplained failures and there was no 

solution to improve this adhesive’s ability to adhere in wet conditions, its ‘wet stick.’ 

 In the earliest stages of the cooperative agreement StarChase contracted with two adhesive 

consulting groups. They provided input on the following adhesive characteristics StarChase had 

defined in order to address the goal stated above.

 In addition to trialing several pressure sensitive adhesive (PSA) samples in the laboratory, we 

also explored alternative nosecone designs in order to increase the adhesion surface and 

penetration of the PSA into the nosecone. The modifications were designed with a balance between 

impact and resistance to high humidity, heat and cold conditions.

 The principle goal of the new design was to improve flight characteristics of the projectile nose 

cone, improve off-angle adhesion for off-angle surfaces and improve wet adhesion.

• New Nose Cone - After thorough evaluation and testing in multiple 

environments the revised nose cone exhibited unstable flight 

characteristics. Furthermore the reduction in density demonstrated 

the need for additional exploration to meet the objectives of the goal. 

• Formula No. AD-7-69B. Results were unstable and unpredictable in the 

area of “T-Peel” /fast-tack and moist environments. This formula and 

design did not warrant further testing. The table below describes the 

testing. 

• Multiple samples were tested in parallel. Initially, one adhesive 

projectile from each sample was loaded in the launcher and tested for 

flight and adhesion. The results are summarized below.

 After unsatisfactory outcomes from testing with leading formulas, StarChase began working

with an additional adhesive vendor adhesive. This third adhesive produced significant improvement 

in the field and we have been able to expand our capabilities based upon testing and subsequent 

field deployments. 

 The third formula was the selected adhesive based upon testing, over 100 deployments in 

our laboratory, together with field trials, it indicated much improved performance characteristics. 
STARCHASE, LLC

Page 26 of 43

StarChase continued with an additional 100 projectile deployments to test for cycle time and 

extreme temperature performance. 

Performance testing Locations: 

• Arizona for hot, low humidity testing

• Texas for hot, high humidity and dampness conditions

• Virginia Beach, Virginia. Laboratory and road testing with high and low 

temps

• Extreme cold weather down to (-10F ̊) achieved via refrigerated controlled 

test area

 StarChase also continued to explore additional mechanical property improvements and 

reduced the density of the nose cone and adjusted the heating configurations to create broader 

application environments and stronger adhesion. Appendix 7, Projectile Nosecone Specifications, 

Figure 1, shows the density changes implemented. Figure 2-3 also details the baselines specified for 

adhesion temperature control. 

 After evaluating multiple formulas and vendors, the third formula’s “T-Peel” was revealed as 

the most stable and best performing formula. This selection provided the best adhesion 

performance in the widest range of environments and temperatures. As a final step in this 

configuration, StarChase has deployed projectiles with the improved adhesive formula to all test 

beds. The table below provides characteristics of the test results.

Page 29 of 43

Conclusion: 

The adhesive research met with positive results: 

We were able improve wet stick in reference to dew point. This is significant for early 

morning pursuit events. 

The adhesive cold weather deployment was reduced by 80 F with a caveat that in snow 

and/or high humidity conditions the adhesive reverts back to a wet stick limitation. 

The new adhesive also allowed StarChase to reduce the required ambient temperature in 

the barrel. An added benefit of lowering the required ambient temperature was an improved shelf 

life for the adhesive, as well as a quicker deployment sequence for the officer in the field. 

The nosecone has incorporated a reduction in density, allowing for additional time on target. 

This results in an increase in successful tags. 

See Appendix 7 (Figures 1-3), Nosecone Technical Specifications details the nosecone, 

density table and software syntax changes for ambient temperature and subsequent temperature 

analysis for improved ‘time to arm’ the system. 

At this time, StarChase and our adhesive consultants agree that in a true wet environment 

(rain/snow) there is still a hydroplane effect occurring on the target at the time of impact. To 

combat this, StarChase will revisit a projectile mechanical design approach that incorporates the 

modified density of the nose cone as well as modified projectile configurations. We expect to 

continue exploring this challenge. 

II.D Methodology, Results and Conclusion Goal #3: Air Compressor System 

Goal: Explore adding an air-compressor to the system in order to eliminate the nitrogen canisters as 

a power source, reduce operating cost, stabilize launch pressure, and reduce system maintenance.
STARCHASE, LLC

Page 30 of 43

Methodology: 

 Replacing nitrogen canisters with an affixed air-compressor is a one-time expense solution. 

This integrated system eliminates a user’s need for checking and verifying the nitrogen canister’s 

status in terms of form, fit, and exchangeability and improves system performance and safety to 

personnel. 

 StarChase integrated the SC GEN II system with an on-board air-compressor. The compressor 

supplies the necessary air pressure via inputs from an integrated digital pressure transducer. 

Together the air compressor/transducer configuration of the system ensures consistent, safe 

operation and reliable projectile trajectory. Integrating an air-compressor system allowed SC GEN II 

to maintain the desired pressure to successfully deploy tags in varying environments. Accurate 

system pressure is consistently obtained as the SC GEN II is capable of: 

• Reliable measurement of current and required air pressure for successful 

operation. 

• Calculation of required pressure to support an adequate discharge of air to launch 

projectile. 

• Maintenance of compressed air in a stable condition with no PSI fluctuation with 

minimal power requirements. 

See Figures: 8 through 10 and Appendix: 8, Figure 4 and 5 for Air Compressor integration. 

 The following requirements summarize our baseline search for an appropriate COTS solution

for integration into the system. 

1. Air compressor system 

2. Electrical/mechanical integration with pressure transducer 

3. Pressure relief port and relay 

4. Mechanical interface 

5. Electrical control module

Results: 

 The compressor has been integrated into the system on all fielded test bed units. This 

improvement has significantly increased reliability while reducing the recurring expense of nitrogen 

canisters with a onetime manufacturing cost. 

 The purpose of this goal was to evaluate the reliability and cost effectiveness of an automatic 

air compressor system. The reviews from law enforcement agencies at all field test beds have been 

very positive and this feedback, together with the attendant cost savings, resulted in a permanent

integrated solution going forward. The following are benefits of the SC GEN II configuration with the

air-compressor: 

• Provides dynamic pressure without requiring any officer input. System status 

is indicated via a red/green LED light. 

• System delivers immediate pressure at the time of the event. This has 

significantly increased system reliability and accuracy. 

• Safety limits are incorporated with a safety valve that will trigger if psi is 

above set point. If triggered system will bleed air down to the default set 

point. 

• Maintenance-free operation for the agency 

Conclusion: 

 Replacement of the nitrogen canisters in favor of an air compressor was a SC GEN II solution 

which reduced system maintenance and operating expense every time an officer deployed a tag. 

Another significant benefit is it provides the required pressure on demand. 

II.E Method – Methods, Results and Conclusions Goal #4: Develop Distance Range Detection 

(DRD):

Goal: Targeting and range finding capabilities to measure distance to target/vehicle.

 

Methodology: 

• Evaluate several COTS solutions based upon system requirements with balanced 

consideration toward increase cost of units versus performance. 

• Incorporate the preferred system which is able to embrace the variations of climatic 

conditions, shock, vibration and environmental hazards during typical use. 

• Design an embedded system that is integrated into the SC Gen II console to provide 

audio impulse tones and visual cues. This will allow officers to determine the distance 

between the launcher and the suspect vehicle. When trained, an officer can easily 

distinguish when a vehicle is in range for deployment.

Results:

The table below shows results of testing four different approaches to the problem 

 Option #1: IR-Optic was the initial COTS component selected for evaluation to integrate 

into the SC GEN II system. The IR-Optic measures between a law enforcement vehicle and a suspect 

vehicle by sensing the signal in multiple stages and positions; such as fixed or moving. The IR-Optic 

system device basically transmits “Pulses/IR Signals” or “Pulse Width Modulated (PWM)” signals at 

high frequency response to the SC Gen II Console platform when objects have been detected.

Page 35 of 43

 StarChase laboratory experiments and physical test results revealed that the IR-Optic failed 

to reliably return signals. The primary weakness was sensitivity to ambient and road noise. These 

interferences caused the power output and internal logic to quickly overload. 

 The IR-Optic was rejected as a final design into the SC GEN II system, as the device proved 

unreliable: 

• Automotive turn signal and brake lights confused inputs. 

• Ambient light confused inputs. 

• Sensitive to small objects transient noise. 

 Option #3: The ultra - sonic sensor is a commercial product that is compliant with the US – 

FCC and RoHS guidelines. The ultra-sonic sensor was the second device selected to implement and 

test on the SC GEN II system for distance/range detection. 

The design was modeled to define, measure and detect high speed chase distances between 

vehicles via ultrasonic burst signals. These ultrasonic waves are transmitted through the air. The 

receivers amplify the signals and digitally convert the sound waves into the distance measurement 

output. The transducer converts the signal to the sender and receiver while sensing/detecting

Figure 12: DRD - Ultrasonic Sensor Phase II 

 StarChase laboratory experiments and real-world road testing were used to evaluate the 

ultrasonic configuration. The results determined that the ultrasonic sound waves produced 

unpredictable sound interception from the noise of road speed, sound pressure, and other acoustic 

pressures that reflected and interfered with functionality. The device was unusable at speeds above 

25 mph.

 Ultrasonic sensor design was not a consideration for the SC GEN II system, because of the 

extreme unreliability of the device for the application due to naturally occurring sound and 

vibrations interfering with the necessary feedback to have the system operate reliably. 

• Condition of target surfaces difficult to detect. 

• Object distance detection was unstable during pursuit speeds. 

• Weak signal returns created erratic results. 

 Option #4: Radar is a commercial product that is compliant with US – FCC and RoHS 

guidelines. Radar was the third device type selected for implementation. Based on the extremely 

high COTS cost, and the additional cost to integrate, StarChase determined the radar approach was 

not cost-effective and concluded, based on total development cost, it was not a viable technology 

solution for the system. 

• Cost of the radar device was too high. 

• Engineering and testing equipment cost deemed too high. 

• Prototypes to run the first article trial tests and evaluations were too costly. 

• Compliance with US-FCC was deemed costly based on potential design 

changes. 

 Solid-State Laser (SSL) was the last of the four devices selected for testing and was selected 

over IR-Optic, Sonic, and Radar. SSL provides a favorable system architecture, electrical physical 

layout, electrical schematic, and mechanical/physical system. This option includes an electrical 

interface module and solid state laser distance range detector. 

 Option #2 (Final selection): The Solid-State Laser Distance Range Detector (SSL DRD) is a 

commercial product that is compliant with the US – FCC and RoHS guidelines. This product was 

selected to be integrated into the SC GEN II system to define dynamic range to target. Low rate 

initial production estimates indicated cost effectiveness when buying in larger quantities.

 The SSL DRD, uses an eye-safe laser beam to establish and determine the distance from the 

law enforcement vehicle to a suspect’s vehicle. The program goal is to increase ease-of-use to 

support officers when targeting a suspect’s vehicle. SSL DRD provides the officer with the ability to 

easily know when a suspect’s vehicle is in range. 

 This configuration utilizes a laser pulse/beam directed at a moving object (suspect vehicle) in 

order to measure and calculate the signal’s reflection off the suspect’s vehicle. The signal returning

to the SSL receiver is measured for precise time and wavelength thus determining the distance to 

target. At the same time the system will alert officers that the system is ready to perform: 

• Automatic detection of forward object from 3ft. to 20ft. relative to the 

officer’s SC GEN II equipped vehicle. 

• Automatic audible alert using “impulse” tone when object is detected 

in range and tone suppression when object is out of range. 

• Provides accurate and fast response time/microseconds. 

• Ability for user to override DRD if necessary to launch GPS projectile 

with or without DRD feedback. 

 One SSL DRD system was integrated into the StarChase test vehicle. Prior to the deployment 

of the DRD system StarChase tested and evaluated the system over six hundred and seventy two 

(672) hours by automatically arming the system every fifteen (15) minutes. This is equivalent to 

running the system, non-stop, for 28 days. 

 SSL DRD - Currently deployed and integrated with Gen II systems operated by a southwest 

agency for continued feedback. 

• Four systems with SSL DRD are deployed. These systems have been operating for more 

than twenty thousand miles on the installed vehicles.

• User feedback supports further exploration of the SSL DRD. The primary downside to the 

SSL DRD is the increased cost for an already cost conscious law enforcement community. 

The benefits show very positive results for the user, but further study must be given to 

balance the increase in user friendliness and results, with the total cost of ownership 

equation.

with the SC GEN II system:

Conclusion: 

 The final SSL DRD selection was laboratory tested and also fielded with law enforcement 

users. The users had prior experience with StarChase technology and had used the technology 

successfully without the additional SSL DRD technology. 

 While the overall feedback was positive with respect to providing an alert when a vehicle is 

in or out of range, the overwhelming consideration is the increased cost to the agency. In an already 

difficult economic environment for state and local law enforcement agencies the additional cost to 

provide what could be a limited performance improvement will need to be weighed cautiously. 

 StarChase will continue to gather feedback for this goal and will continue to investigate 

economical ways to implement this technology into the current SC GEN II architecture.

The proposed Research in Brief will be released to all law enforcement communities when 

Dr. Alpert speaks at the upcoming 2014 IACP Conference in Orlando at the Saturday, NIJ track 

session in October. He will specifically address the research outcomes of the test beds and the 

officers’ feedback on the user friendliness of the system. Prior to the IACP conference we are 

mailing post cards and an email campaign in support of this dissemination. 

The research will be released to other core audiences including other related stakeholder 

organizations such as NHTSA, PursuitSAFETY and Officer Down Memorial Page, and associations 

related to the insurance industry. 

We will also disseminate to law enforcement periodicals and media outlets such as the FBI 

Law Enforcement Bulletin, NLECTC’s Tech Beat, The Police Executive Research Forum, the 

International Association of Chiefs of Police, the National Sheriff’s Association, the National 

Organization of Black Law Enforcement Executives, The Fraternal Order of Police, Commission on 

Accreditation for Law Enforcement Agencies and any related programs such as COPs and BJA. 

We have received past positive news coverage in the past from USA Today, Popular

The evidence of safe outcomes revealed in our case studies creates an opportunity for 

legislators to have a positive national impact on citizen safety with a tool that makes a difference for 

law enforcement officers serving our communities. We are actively working with our government 

representatives to support initiatives that allow LEAs to trial the technology with the support of 

grant funding including the Justice Assistance Grant (JAG), Community Oriented Policing Services 

(COPS) and Governor’s Highway Safety Association grants with funding provided by NHTSA. 

The dissemination strategy is a key part of the program conclusion as agencies are actively 

seeking additional grant funding in order to adopt the technology. We are working collaboratively 

with LEAs and insurance agency risk managers to determine a cost/benefit analysis protocol to 

specifically address the reduction in risk and related liabilities when StarChase is part of a police 

force’s toolbox. 

This technical report summarizes the results of our cooperative agreement. The NIJ has been 

studying police pursuit outcomes since the late 1980s and has been seeking a solution to this 

ongoing problem. We are pleased that the preliminary research from StarChase indicates a game 

changing technology is making a tactical difference in the ongoing management of police pursuits 

and reducing agency risk and liability.

STARCHASE REPORT 

Proposed Research in Brief 

Geoffrey P. Alpert 

University of South Carolina 

July 31, 2014 

This project was supported by Award No. 2010-IJ-CX-K022, awarded by the National Institute of Justice, Office of Justice Programs, U.S. 

Department of Justice. The opinions, findings, and conclusions or recommendations expressed in this publication/program/exhibition are those

 In order to investigate how StarChase functions in the real-world, the experiences of 

two different types of agencies were examined. Both an agency that patrols highways and 

freeways, the Arizona Department of Public Safety, and a large urban police department, the 

City of Austin, Texas were assessed. This Report describes the experiences as reported by 

officers who are most familiar with the technology and activities in the two agencies. 

The Arizona Department of Public Safety 

During the night of 31 January 2013, Officer Korey Lankow of the Arizona Department of 

Public Safety took me on a ride-along to observe him during his shift and to discuss his 

experiences with StarChase. After signing the Consent Form and briefing me on my 

responsibilities as a civilian observer, Officer Lankow took me with him while he performed his 

customary tasks. Officer Lankow stopped a number of vehicles for a variety of violations and 

interacted with the drivers and passengers in a professional and courteous manner. Once the 

traffic stops ended, he briefed me on what he was looking for and how he interpreted the cues 

and signs he observed from the drivers and passengers. He explained to me the potential 

hiding places for drugs on the different vehicles he stopped, and how he read the driver’s 

signals and cues. 

The driving time was spent discussing the issues of pursuits in general and StarChase 

specifically. Officer Lankow has deployed StarChase 21 times and is likely the person who has 

deployed it more often than anyone else in the line of duty. He has deployed it using the 

remote and interior triggers and at low speeds and high speeds. He has had successful 
3 

applications, with subsequent apprehensions and seizures of contraband and unsuccessful 

applications where the projectile did not stay on the vehicle. Overall, he believes StarChase is a 

device that has made policing less risky for himself, the community and the fleeing suspects and 

their passengers. 

StarChase is a device that is designed to tag and track a vehicle that flees from the 

police. It involves firing a projectile that has a GPS sending unit embedded into a projectile that 

is deployed from the police car. The projectile has adhesive that adheres to the target vehicle 

without the driver knowing about it. On 1 February, I spent time with Officer Keith Duckett of 

the Arizona Department of Public Safety who has deployed StarChase ten times and is currently 

waiting for the device to be installed in his new vehicle. I also spoke to Major Larry Scarber of 

the Southern Patrol Bureau. Officer Rob Telles was not available during my site visit but has 

deployed StarChase three times. The following observations reflect a compilation of the 

officers’ comments, ideas, perspectives and thoughts that were discussed during my two day 

site visit with the Arizona Department of Public Safety officers. 

The Arizona Department of Public Safety has been an agency that has historically been 

involved in a relatively large number of pursuits. The Southern Patrol Bureau, whose 

headquarters is in Tucson, is responsible for a large area and population including highways and 

freeways where drug smugglers are known to travel. The officers are trained to look for a 

variety of cues to help them determine the likelihood of someone carrying drugs or drug 

money. StarChase is designed to track violators without raising the risk to the public and was 

welcomed by the Arizona Department of Public Safety and its officers who were selected to test 

it. 
4 

StarChase requires that it be armed or “warm up” before deployment, which takes 

approximately 10 seconds. The normal process is for officers to arm the unit prior to initiating a 

stop so it is ready for use. This process also involves the use of a laser light to aim the 

projectile. Officers do not always arm the system and usually do so only when they have 

indicators that there is a reasonable chance the suspect will flee. When pressed about the 

indicators, the officers rely on their “gut” feeling and experience to decide when to arm 

StarChase. The officers did explain that certain types of vehicles have better potential hiding 

places than others and are used more often by drug smugglers. 

As with any new technology, there are aspects of StarChase that are improved with 

testing and experience. The officers explained that after only a few deployments in training 

and experience aiming StarChase they become comfortable in its use and limits. The most 

complicated aspect of StarChase is aiming it by manipulating the unit by using the internal 

controls and/or by steering the police car to point the device, which is aided by a laser light. 

Training and experience can bring an officer to a comfort level, but the tasks involved in aiming 

the unit at high speeds can be tricky and risky. During the beginning phases of testing, officers 

had experience with cartridges that did not stick to the target vehicles. Some of the early 

applications failed as the cartridges would bounce off the targets. This failure was reported and 

corrected by the manufacturer and recently these officers have not experienced any failures. 1

Another issue raised was the timing of the device that armed StarChase. In one instance an 

officer was concerned about the potential of a target vehicle fleeing and armed StarChase in 

 

1

 Major Scarber has reported that other officers, Casey Yartym and Howard McDonald, have experienced recent 

failures where the projectiles failed to stick to suspect vehicles. 
5 

anticipation of the stop. Unfortunately, the stop did not occur immediately and StarChase 

“cycled off” and when the officer went to deploy, it was not armed and ready. While the officer 

admitted it was his error in not re-arming the unit, it is important to understand that they have 

a lot of things to think about and if possible the technology should assist them as much as 

possible. 

Before deploying StarChase, it is necessary to aim it with use of the laser beam. The 

current units utilize a small green laser or beam to help the officer aim the unit. The light shows 

as a dot on the vehicle which is the target location. The officer can aim the unit by 

manipulating it with directional controls inside the vehicle. It can also be aimed by steering the 

car to improve the contact point until the dot is where the cartridge is intended to hit. While I 

did not observe this light from a target vehicle, I did hear a suspect ask about the green light he 

saw in his rear-view mirror prior to being pulled over. 

Normally, the arming, aiming and deploying StarChase is a relatively simple set of tasks 

that takes minimal training to become proficient. The major difficulty with StarChase is during 

high-speed deployments, possibly at speeds between 80 – 100 MPH. These deployments 

require the officer to drive fast and within 20 feet of the target vehicle before StarChase can be 

deployed. While the officers were comfortable with their abilities to drive aggressively to 

deploy StarChase, they agreed that not all officers would want to take those risks by driving so 

fast at such a close proximity to the fleeing vehicle. The officers also were comfortable that 

many officers would be comfortable executing such a maneuver and that many officers have 

asked how they could get a StarChase in their vehicle. 
6 

Once StarChase is deployed successfully the officers terminated their active attempt to 

pursue the fleeing suspect by turning off all emergency equipment and slowing down and 

blending into traffic. This allowed the fleeing suspect to “escape,” and after realizing the police 

were no longer trying to catch them they would slow down. StarChase creates data that shows 

the exact time, speed and distance that “tagged” vehicles travel until they slow down or return 

to the speed limit. The officers report that they would have terminated many of the pursuits in 

which they tagged vehicles because of the risks created by the traffic congestion, extreme 

speeds, and/or other environmental factors. Some of the pursuits would have been continued 

and the outcome while unknown may likely have ended negatively with crashes or injuries. 

Without StarChase many offenders would have escaped and many of them and innocent 

civilians could have been injured. Because of the tagging and tracking, many of them were 

arrested without incident and their contraband seized. An interesting but unintended 

consequence of Star Chase was noted by Major Scarber. He is aware of several situations 

where officers under his command have not initiated stops of vehicles that have been 

confirmed as stolen, or when the officer has a belief that the driver may flee, when a police 

vehicle with Star Chase is in the area. Rather than initiating the stop, the officer will call for the 

police vehicle with Star Chase to tag the vehicle before initiating the stop. While it is not known 

how many vehicles have fled in these situations, it is an important behavior to document in the 

future. See Appendix A for 36 case studies of successful applications of StarChase. 

 One specific example (case study #2) of a successful tag involved a pick-up truck with 

nine "illegal" teenage girls from Mexico. The driver of the pick-up pulled over when the officer 

initiated an enforcement stop but fled as the officer approached the vehicle after stopping it. 
7 

StarChase was remotely activated. The vehicle fled at a high rate of speed and slowed only 

after the driver realized he wasn't being chased. The pick-up was tracked to the "stash house," 

the girls were located hiding in the pick-up and brought to Immigration Customs Enforcement 

(ICE) and interviewed. Arrests were made and the girls stated they were told they were headed 

to the east coast to be maids and housekeepers for wealthy Americans, it is very likely they 

were headed to be traded as sex slaves. As the officer said, "Drugs/ money/weapons/stolen 

vehicles receive much attention, but human life is more valuable than all of these. Without this 

technology, I would have pursued the truck and based on the recorded speeds after fleeing, all 

occupants may have been killed if the vehicle crashed. This was an incident I wanted to share 

because it involved possible loss of human life; priceless." 

This example shows why the officers are very enthusiastic about the future of 

StarChase. They recommended its use by other agencies but caution that it requires risk taking 

and advanced driving skills. The selection of officers who use it is an important consideration. 

Austin, Texas Police Department 

On July 2, 2014 I met with Officer Marcus Davis, at the Technology Unit of the Austin, 

Texas Police department (APD). Officer Davis is in charge of keeping track of the StarChase 

deployments for APD and is an expert in the technology and conducts the training for the APD 

officers. He relayed that StarChase has been deployed 25 times in the 13 months that it has 

been available at APD, and they have a success rate of 55%, meaning that the GPS Tags stuck to 

the vehicle and arrests were made in each of the successful deployments. 
8 

He explained that in some deployments, even when the GPS Tags did not stick on the 

targeted vehicle, drivers pulled over because they were startled by the noise of the Tag hitting 

the car. He showed several videos of those events as well as other deployments when the Tags 

stuck to the targeted vehicles. He also explained that most of the unsuccessful deployments 

were due to the officers not following training and deploying the Tags in wet weather or not 

lining up the target properly. He showed several videos of these examples. 

Officer Davis stated that he has spoken to the deploying officers and has heard multiple 

comments that they feel safe and more confident with StarChase as they can keep more 

distance between them and the suspect vehicle and do not have to take unnecessary driving 

risks. He concluded our conversation by stating how much he liked the StarChase technology as 

an added tool in the officer’s toolbox, and said, “I would buy stock in the company.” 

Summary 

This initial assessment of the experiences from two different law enforcement agencies 

showed great promise for StarChase and its ability to be a “game changer” for law 

enforcement. While there are selection issues for officers, and it will be necessary to check and 

perhaps modify training protocols and proficiency testing, the results of successful applications 

to date are impressive. Suspects whose vehicles are tagged behave as if they are free from the 

police and slow down when the police stop chasing, in many cases within a minute. The 

behavior of the fleeing suspects demonstrates no knowledge that they are being tracked by a 

GPS system that pinpoints their location and speed in real time. In most cases, officers have 

tactically apprehended suspects and seized vehicles and contraband without creating a risk to 

the public, themselves or the suspect or any passengers. 
9 

The present assessment is a preliminary step in an evaluation process that will require 

an in-depth analysis of multiple StarChase units used by different officers in a variety of 

agencies. A comprehensive evaluation will need to explore deployment decisions and 

strategies, data on effectiveness and results of applications in different situations and 

environments, officer’s and suspect’s perceptions of StarChase and the impact of the 

technology on the organization, including behavior changes of officers who are not using Star 

Chase. 
10 

Appendix A 

Case Studies 

StarChase has the ability to track fleeing suspects, and apprehend them without a dangerous 

pursuit. The anecdotal information provided by officers who have used the device is impressive and 

shows how well the technology performs in the field. One of the major concerns of a pursuit is the 

behavior of the fleeing suspect who drives dangerously and recklessly, often checking his or her 

rearview or side mirrors to determine where the pursuing police car is located and if it still has its

emergency lights illuminated and if it is still chasing. Up until now, the only information we have had 

concerning the actions of the fleeing driver is an estimate of the pursuing police officer or the fleeing 

suspect (Schultz et al., 2009). StarChase sends back real-time information on the speed, direction and 

location of the target vehicle to the computer that maintains communication with StarChase. There are

a total of 36 case studies submitted with this report. 

 The data was collected from the established NIJ test beds and StarChase customers, who have 

agreed to participate in the data collection. When a tag is successfully deployed, there have been no 

follow-on high-speed pursuits, loss-of-life, injuries or property damage and. Out of the 36 case studies, 

there were a total of: 

• 13 stolen vehicles recovered with no property damage 

• 25 humans rescued due to human smuggling plus three children that were in a fleeing vehicle 

during the pursuit. 

• 2 DUIs resolved with no loss-of-life 

• Over 4000 lbs. of drugs recovered 

• 44 Arrests were made 

On average, the case studies also report the time to return to within 10 MPH of a posted speed limit is 

under two minutes and a +80% apprehension rate. 10 MPH is an estimate of the time it takes for a 

vehicle to blend into traffic and return to “normal driving behavior” which is no longer aggressive, 

evasive or impulsive. 

Case Study #1 

 A vehicle was identified as stolen by the officer. The vehicle took off reaching a top speed of 78 

MPH and the total tracking time was 3 Min 50 Sec. The officer did not chase and 1 Min 40 Sec after 

being tagged, the vehicle slowed within 10 MPH of the speed limit. There were no injuries, accidents or 

property damage. There were three arrests and a gun recovered. 

Case Study #2 

 A vehicle was observed that the officer suspected was transporting drugs or people. The vehicle 

took off reaching a top speed of 68 MPH and the total tracking event lasted 4 Min 31 Sec. The officer did 

not chase and within 2 Min 45 Sec after being tagged, the vehicle slowed within 10 MPH of the speed 

limit, and it was driven to a house where officers arrested the driver and rescued nine young females.

Case Study #3 

 A vehicle was observed that the officer suspected was stolen. The vehicle took off reaching a 

top speed of 90+ MPH and the total tracking event lasted 24 Min. The officer did not chase and 15 Min 
11 

after being tagged, the vehicle slowed within 10 MPH of the speed limit. The driver of the stolen vehicle 

was arrested, the vehicle was recovered. 

Case Study #4 

 The officer suspected a car was carrying narcotics and was travelling almost 100 MPH. The 

tracking event lasted 5 Min 31 Sec and there was no chase. 4 Min after being tagged, the vehicle slowed 

within 10 MPH of the speed limit. The driver of the stolen vehicle was arrested along with one other,

the vehicle was recovered and 500+ lbs. of drugs was confiscated. 

Case Study #5 

 A vehicle was observed at 84 MPH and the officer suspected it was stolen. The tracking event 

lasted 10 Min 40 Sec and there was no chase. 2 Min 30 Sec after being tagged, the vehicle slowed 

within 10 MPH of the speed limit. The driver of the stolen vehicle was arrested along with one other,

and two children were safely removed from the vehicle. 

Case Study #6 

 A vehicle was observed that the officer suspected was carrying narcotics in the car. The tracking 

event lasted 18 Min and there was no chase. 6 Min after being tagged, the vehicle slowed within 10 

MPH of the speed limit. 200+ lbs. of drugs were confiscated. 

Case Study #7 

 A vehicle was observed at 90+ MPH and the officer suspected there were narcotics in the car. 

The tracking event lasted 2 Min and there was no chase. 50 Sec after being tagged, the vehicle slowed

within 10 miles per hour of the speed limit. 700 lbs. of drugs were confiscated. 

Case Study #8 

 A vehicle was observed at 83 MPH and the officer suspected it was carrying narcotics. The 

tracking event lasted 12 Min and there was no chase. 3 Min after being tagged, the vehicle slowed 

within 10 MPH of the speed limit. Two arrests were made, 1600 lbs. of drugs and a vehicle were 

recovered. 

Case Study #9 

 A vehicle was observed at 85 MPH and the officer suspected it was a drug scout car. The 

tracking event lasted 50 Min. and there was no chase. 6 Min after being tagged, the vehicle slowed 

within 10 MPH of the speed limit. No arrests were made, but the vehicle was recovered. 

Case Study #10 

 Officer proactively tagged a stolen vehicle. Tagged at 17 MPH and the vehicle yielded. It did not 

exceed the speed limit. 

Case Study #11 

 Officer tagged a stolen vehicle with a top speed of 50 MPH and the driver did not exceed the 

speed limit. Driver originally fled but was found and arrested. The tracking event lasted 2 Min. 

Case Study #12 

 Officer tagged a suspected DUI and the entire tracking event lasted 2 Min 42 Sec. The individual 

did not exceed the speed limit and was arrested for DUI with a top speed of 47 MPH. 
12 

Case Study #13 

 Officer tagged a suspended license plate and the tracking event lasted 3 Min 30 Sec with a top 

speed of 56 MPH. Suspect arrested prior to urban no pursuit area and did not exceed the speed limits. 

Case Study #14 

 Officer tagged a suspected DUI and the entire tracking event was 2 Min 43 Sec. The tag was 

deployed at 54 MPH and the vehicle did not exceed speed limit. Arrest was made. 

Case Study #15
