Introduction

In 2013, the president signed into law the Investigative Assistance for Violent Crimes 

Act of 2012, which granted the attorney general the authority to assist in the investigation of “violent acts and shootings occurring in a place of public use” and in the investigation of “mass killings and attempted mass killings at the request of an appropriate law 

enforcement official of a state or political subdivision.”1

To provide further clarity on these threats, the Federal Bureau of Investigation (FBI) 

in 2014 initiated a study of “active shooter” incidents2. The goal of the FBI study is to 

provide federal, state, and local law enforcement with data so they can better understand 

how to prevent, prepare for, respond to, and recover from these incidents. 

Active shooter is a term used by law enforcement to describe a situation in which a shooting is in progress and an aspect of the crime may affect the protocols used in responding 

to and reacting at the scene of the incident. Unlike a defined crime, such as a murder or 

mass killing, the active aspect inherently implies that both law enforcement personnel and 

citizens have the potential to affect the outcome of the event based upon their responses. 

1 Investigative Assistance for Violent Crimes Act of 2012, 28 USC 530C(b)(1)(M)(i).

2 The FBI’s Uniform Crime Reporting system does not capture data specific to active shooters but rather is data derived from more than 18,000 city, 

university/college, country, state, tribal, and federal law enforcement agencies that voluntarily report monthly on criminal activity in their jurisdictions.

The agreed-upon definition of an active shooter by U.S. government agencies—including 

the White House, U.S. Department of Justice/FBI, U.S. Department of Education, and 

U.S. Department of Homeland Security/Federal Emergency Management Agency—is 

“an individual actively engaged in killing or attempting to kill people in a confined and 

populated area.”3 Implicit in this definition is that the subject’s criminal actions involve the 

use of firearms.4

For purposes of its study, the FBI extended this definition to include individuals, because 

some incidents involved two or more shooters. Though the federal definition includes the 

word “confined,” the FBI excluded this word in its study, as the term confined could omit 

incidents that occurred outside a building. 

Whether inside or out, these incidents still posed a threat to both law enforcement and the 

citizens they seek to protect.5

Incidents identified in this study do not encompass all gun-related situations; therefore 

caution should be taken when using this information without placing it in context. Specifically, shootings that resulted from gang or drug violence—pervasive, long-tracked, criminal 

acts that could also affect the public—were not included in this study. In addition, other 

gun-related shootings were not included when those incidents appeared generally not to have 

put others in peril (e.g., the accidental discharge of a firearm in a school building or a person 

who chose to publicly commit suicide in a parking lot). The study does not encompass all 

mass killings or shootings in public places and therefore is limited in its scope.6 Nonetheless, 

it was undertaken to provide clarity and data of value to both law enforcement and citizens as 

they seek to stop these threats and save lives during active shooter incidents.7

As a result, the FBI identified 160 active shooter incidents that occurred in the United States 

between 2000 and 2013.8 Though additional active shooter incidents may have occurred 

during this time period, the FBI is confident this research captured the vast majority of 

incidents falling within the search criteria. To gather information for this study, researchers 

relied on official police records (where available), FBI records, and open sources.9 The 

time span researched was intended to provide substantive results to aid in preparedness and 

response efforts. This study is not intended to explore all facets of active shooter incidents, 

but rather is intended to provide a baseline to guide federal, state, tribal, and campus law 

enforcement along with other first responders, corporations, educators, and the general 

public to a better understanding of active shooter incidents.

6 Other private and public entities have studied mass casualty incidents, murder rates, and school or workplace violence. (e.g., Campus Attacks: 

Targeted Violence Affecting Institutions of Higher Education, a joint publication of U.S. Secret Service, U.S. Department of Education, and Federal Bureau of 

Investigation, 2010, http://rems.ed.gov/docs/CampusAttacks_201004.pdf).

7 Limited details on the shooters are included in this study. In 2015, the FBI Behavioral Threat Assessment Center will research shooter pre-attack behavioral indicators with a focus on findings that will enhance prevention methods.

Snapshot

The following characteristics of the 160 active shooter incidents 

identified between 2000 and 2013 are noted:

INCIDENTS

■ An average of 11.4 incidents occurred annually.

■ An average of 6.4 incidents occurred in the first 7 years studied, and an average of 16.4 

occurred in the last 7 years.

■ 70.0% of the incidents occurred in either a commerce/business or educational 

environment10.

■ Shootings occurred in 40 of 50 states and the District of Columbia.

■ 60.0% of the incidents ended before police arrived. 

10 All percentages are rounded to the nearest tenth

*

A handful of those identified as “wounded” were not injured by gunfire but rather suffered injuries incidental to the event, such as being hit by flying objects/shattered glass or 

falling while running. This does not account for all those wounded in this fashion or any mental or emotional trauma that resulted in potential medical treatment.

CASUALTIES

■ Casualties (victims killed and wounded) totaled 1,043. The individual shooters are not 

included in this total.

■ A total of 486 individuals were killed.

■ A total of 557 individuals were wounded.11

■ In 64 incidents (40.0%), the crime would have fallen within the federal definition of 

“mass killing”—defined as “three or more” killed—under the new federal statute. 

INCIDENTS WITH THE HIGHEST CASUALTY COUNTS:

■ Cinemark Century 16 Theater in Aurora, Colorado:

70 (12 killed, 58 wounded), July 20, 2012.

■ Virginia Polytechnic Institute and State University in Blacksburg, Virginia:

49 (32 killed, 17 wounded), April 16, 2007.12

■ Ft. Hood Soldier Readiness Processing Center in Ft. Hood, Texas:

45 (13 killed, 32 wounded), November 5, 2009.

■ Sandy Hook Elementary School and a residence in Newtown, Connecticut:

29 (27 killed, 2 wounded), December 14, 2012.

SHOOTERS

■ All but 2 incidents involved a single shooter.13

■ In at least 9 incidents, the shooter first shot and killed a family member(s) in a 

residence before moving to a more public location to continue shooting.14

■ In at least 6 incidents, the shooters were female.15

■ In 64 incidents (40.0%), the shooters committed suicide; 54 shooters did so at the scene 

of the crime. 

■ At least 5 shooters from 4 incidents remain at large.16

11 A handful of those counted as wounded were not injured by gunfire but rather suffered injuries incidental to the event, such as being hit by flying 

objects/shattered glass, or falling while running. These were included in the casualty count when research may not have easily allowed for the type of 

injury to be discerned. This does not account for all those wounded in this fashion, to include those suffering any mental or emotional trauma that resulted 

in potential medical treatment.

12 Six additional students were injured after they climbed out of a second floor window in Norris Hall but are not included in the study’s tally of those 

wounded because they could be easily discerned from those wounded by the shooter.

Findings

In this study, the FBI identified 160 active shooter incidents, noting they occurred in small 

and large towns, in urban and rural areas, and in 40 of 50 states and the District of Columbia. 

Though incidents occurred primarily in commerce and educational environments (70.0%), 

they also occurred on city streets, on military and other government properties, and in private 

residences, health care facilities, and houses of worship. The shooters victimized young and 

old, male and female, family members, and people of all races, cultures, and religions.

The findings establish an increasing frequency of incidents annually. During the first 7 years 

included in the study, an average of 6.4 incidents occurred annually. In the last 7 years of 

the study, that average increased to 16.4 incidents annually. This trend reinforces the need to 

remain vigilant regarding prevention efforts and for law enforcement to aggressively train to 

better respond to—and help communities recover from—active shooter incidents. 

The findings also reflect the damage that can occur in a matter of minutes. In 64 

incidents where the duration of the incident could be ascertained, 44 (69.0%) of 64 

incidents ended in 5 minutes or less, with 23 ending in 2 minutes or less. Even when law 

enforcement was present or able to respond within minutes, civilians often had to make 

life and death decisions, and, therefore, should be engaged in training and discussions on 

decisions they may face.17

17 In 6 incidents (and, in addition, at least 4 schools), officers were on the scene when the shooting began.

As expected, therefore, many incidents ended before police arrived.18 Of the 160 

incidents, at least 107 (66.9%) ended before police arrived and could engage the shooter, 

either because a citizen intervened, the shooter fled, or the shooter committed suicide or 

was killed by someone at the scene. 

Casualties

A total of 1,043 casualties occurred during the incidents included in this study (486 killed, 

557 wounded). If a shooter died as a result of the incident, that individual was not included 

in the casualty totals. In addition, a small number of those identified as wounded were not 

injured by gunfire but rather suffered injuries incidental to the event, such as being hit by 

flying objects/shattered glass or falling while running. For the purposes of this study, the 

FBI did not seek to isolate the exact number of individuals that fell into this category, when 

research did not allow for that type of injury to be easily discerned.

The median number of individuals killed in each incident was 2, and the median number of 

individuals wounded in each incident was 2.

The FBI found that 64 incidents (40.0%) would have been categorized as falling within 

the new federal definition of “mass killing,” which is defined as “three or more killings in 

a single incident.”19

18 According to the 2007 National Crime Victimization Survey, 53.4% of the time, law enforcement was able to respond to a reported violent 

crime in less than 10 minutes. Bureau of Justice, National Crime Victimization Survey, Criminal Victimization in the United States, 2007 Statistical 

Tables, February 2010.

At least 25 (15.6%) of the 160 incidents involved shootings at more than one location. 

Several casualties involved family members or individuals who had a close personal relationship with the shooter. In at least 15 (9.4%) of the 160 incidents, the shooters targeted family 

members, resulting in the deaths of 20 and the wounding of 1.20 In 9 of these incidents, or 

about half, the shooters then moved on to another location and continued shooting. 

Of note, male shooters also acted violently against women with whom they had or once had 

a romantic relationship. In 16 (10.0%) of the 160 incidents, the shooters targeted current, 

estranged, or former wives as well as current or former girlfriends. In 12 incidents, the 

women were killed;21 in 3 incidents, the women sustained significant injuries but survived;22

and in 1 incident, the shooter could not find the woman.23 While perpetrating this violence, an 

additional 42 people were killed and another 28 were wounded.

Resolutions

The majority of the 160 incidents (90 [56.3%]) ended on the shooter’s initiative—

sometimes when the shooter committed suicide or stopped shooting, and other times when 

the shooter fled the scene. 

There were at least 25 incidents where the shooter fled the scene before police arrived. In 4 

additional incidents, at least 5 shooters fled the scene and were still at large at the time the 

study results were released.

In other incidents, it was a combination of actions by citizens and/or law enforcement that 

ended the shootings. In at least 65 (40.6%) of the 160 incidents, citizen engagement or the 

shooter committing suicide ended the shooting at the scene before law enforcement arrived. 

Of those:

■ In 37 incidents (23.1%), the shooter committed suicide at the scene before police 

arrived.

■ In 21 incidents (13.1%), the situation ended after unarmed citizens safely and successfully restrained the shooter. In 2 of those incidents,24 3 off-duty law enforcement 

officers were present and assisted. 

■ Of note, 11 of the incidents involved unarmed principals, teachers, other school 

staff and students who confronted shooters to end the threat (9 of those shooters 

were students). 

■ In 5 incidents (3.8%), the shooting ended after armed individuals who were not law 

enforcement personnel exchanged gunfire with the shooters. In these incidents, 3 shooters were killed, 1 was wounded, and 1 committed suicide.

■ The individuals involved in these shootings included a citizen with a valid firearms 

permit and armed security guards at a church, an airline counter, a federally 

managed museum, and a school board meeting.25

■ In 2 incidents (1.3%), 2 armed, off-duty police officers engaged the shooters, resulting in the death of the shooters. In 1 of those incidents, the off-duty officer assisted a 

responding officer to end the threat.26

Even when law enforcement arrived quickly, many times the shooter still chose to end his 

life. In 17 (10.6%) of the 160 incidents, the shooter committed suicide at the scene after law 

enforcement arrived but before officers could act.

In 45 (28.1%) of the 160 incidents, law enforcement and the shooter exchanged gunfire. Of 

those 45 incidents, the shooter was killed at the scene in 21, killed at another location in 4, 

wounded in 9, committed suicide in 9, and surrendered in 2.

Law Enforcement/Security 

Personnel Casualties

Law enforcement suffered casualties in 21 (46.7%) of the 45 incidents where they engaged 

the shooter to end the threat. This resulted in 9 officers killed (4 of whom were ambushed in 

a shooting) and 28 wounded. 

In 3 (1.9%) of the 160 incidents, armed, non-sworn security personnel were killed.27 In 2 

additional incidents, 2 unarmed security officers were killed and 2 were wounded.28

Shooter Outcomes 

In all, 64 (40.0%) of the shooters ultimately committed suicide. Most shooters were males 

acting alone. Only 2 (1.3%) of the 160 incidents had more than 1 shooter and only 6 (3.8%) 

involved a female shooter. Of note, 2 of the 12 shootings at institutions of higher education 

(IHEs) were perpetrated by females. At least 5 shooters were at large at the time of the 

publication of this study.

Results showed 3 shooters carried improvised explosive devices (IEDs); 1 shooter used the 

device (a Molotov cocktail).29 And, 1 shooter booby-trapped his residence with IEDs.30 At 

least 6 shooters wore or were carrying body armor. 

Locations

The FBI identified 11 separate incident location categories31 when seeking to identify the 

primary locations where the public was most at risk during an incident. These location 

categories include commercial areas (divided into malls, businesses open to pedestrian 

traffic, and businesses closed to pedestrian traffic), educational environments (divided into 

schools [pre-kindergarten through 12th grade] and IHEs), open spaces, government properties (divided into military and other government properties), residences, houses of worship, 

and health care facilities. 

When an incident occurred in two or more locations, the FBI sought to identify where 

the public was most at risk. For example, in instances where casualties occurred inside a 

private residence before a shooter moved to a public area, those incidents were categorized at the location where the public was more at risk. In addition, some specialized 

business locations (i.e., malls and health care facilities) were identified separately to 

provide added transparency.

In all, 24 (15.0%) of the 160 incidents involved shootings at more than one location. This 

supports the value in quickly assessing the circumstances where the first shooting occurs 

and may aid law enforcement’s ability to predict other potential targets.

The study results identified 73 (45.6%) of 160 incidents that occurred in areas of commerce. 

These included businesses open to pedestrian traffic (44 [27.5%]), businesses closed to 

pedestrian traffic (23 [14.3%]), and malls (6 [3.8%]). These distinctions were made in order 

to determine whether the public was more at risk in areas where pedestrian traffic was likely.

Educational environments were identified as the second-largest location grouping (39 

[24.4%]). These were further broken down as those occurring in schools (27 [16.9%], 

including two school board meetings) and IHEs (12 [7.5%]).

COMMERCE AREAS

Businesses Open to Pedestrian Traffic 

The 44 incidents that occurred in business environments generally open to pedestrian 

traffic resulted in 124 people killed (including 2 company co-owners in 1 incident) and 

181 people wounded (including 1 manager). The most incidents occurred on Tuesdays 

(10), with others occurring on Fridays (9), Mondays (6), Wednesdays (6), Thursdays (5), 

Sundays (5), and Saturdays (3).

The majority of the shooters in these incidents were not employed at the location. 

Specifically:

■ 30 shooters (68.2%) were not employed by the businesses, though 7 had a relationship 

with at least 1 current employee; 

■ 12 shooters (27.3%), including 1 woman, were employed or previously employed by 

the businesses (8 current employees [2 possibly facing termination, 1 terminated the 

day of the shooting] and 4 former employees); and

■ 2 or more shooters from 2 incidents fled the scene and remain at large, so their connection to the incident location is unknown. 

These incidents ended when:

■ 19 shooters committed suicide (11 did so at the scene before police arrived, 3 did so at 

the scene after police arrived, and 5 shooters fled the scene and committed suicide at 

another location);

■ 9 shooters were apprehended at the scene (1 after being restrained by a citizen);

■ 8 shooters fled and were apprehended by law enforcement at another location;

■ 4 shooters were killed by law enforcement (2 at the scene);

■ 2 shooters fled and were not apprehended;

■ 1 shooter was killed by an off-duty law enforcement officer at the scene; and

■ 1 shooter was killed at the scene by a citizen with a valid firearms permit.

Businesses Closed to Pedestrian Traffic

The 23 incidents that occurred in business environments generally closed to pedestrian 

traffic resulted in 69 individuals killed and 73 wounded. In 12 incidents, supervisors/managers and owners of companies were killed (10) or wounded (5). The most incidents occurred 

on Wednesdays (7), with others occurring on Tuesdays (5), Thursdays (4), Mondays (3), 

Fridays (2), and a Sunday (1).

These incidents almost exclusively involved employees. In all, 22 of the 23 shooters, 

including 2 females, were employed or previously employed at the business. The sole 

shooter not employed by a business had a relationship with a current employee. The 22 

shooters who were employees included:

■ 14 current employees;

■ 4 employees fired the day of the shooting;

■ 3 former employees; and 

■ 1 suspended employee.

■ 3 shooters were apprehended at the scene (2 after being restrained by citizens);

■ 3 shooters were killed by police (2 at the scene and 1 elsewhere); and

■ 1 shooter fled and was apprehended by police at another location.

Malls

The 6 incidents that occurred in malls resulted in 17 killed and 18 wounded. It appeared the 

shooters were neither employed by businesses in the affected malls nor had relationships 

with mall employees. The most incidents occurred on Sundays (2), with others occurring on 

a Monday (1), a Tuesday (1), and Wednesday (1), and a Thursday (1).

These incidents ended when: 

■ 3 shooters committed suicide at the scene before law enforcement arrived;

■ 2 shooters were apprehended by law enforcement at the scene (1 after being restrained 

by a citizen); and 

■ 1 shooter was killed by law enforcement during an exchange of gunfire with responding officers, including an off-duty officer at the mall at the time.

EDUCATION ENVIRONMENTS

 The 39 incidents that occurred in educational environments (27 schools, 12 IHEs) 

resulted in 117 individuals killed and 120 wounded. Note that in this study, schools are 

defined as pre-kindergarten through 12th grade (PreK-12) educational facilities; incidents 

that occurred at school-related facilities such as school administration buildings are also 

included in this category.

Incidents in educational facilities account for some of the higher casualty counts. For 

example, the highest death tolls among the 160 incidents occurred at Virginia Polytechnic 

Institute and State University in Blacksburg, Virginia (32 killed, 17 wounded) and Sandy 

Hook Elementary School in Newtown, Connecticut (26 killed, 2 wounded [1 additional 

death at a residence]). Other high casualty counts occurred during the shootings at Northern 

Illinois University in DeKalb, Illinois (5 killed, 16 wounded) and Santana High School in 

Santee, California (2 killed, 13 wounded).

No law enforcement officers were killed or wounded in school incidents, and no officers 

were killed in incidents at IHEs. One officer was wounded in 1 incident at an IHE, however, 

it occurred at a medical facility on the campus and not in a campus residence or classroom.

IHEs

The 12 IHE shootings resulted in 60 individuals killed and 60 individuals wounded. The 

shooters, 2 of whom were female, ranged in age from 18 to 62. The shooters included 5 

former students, 4 current students, 2 employees, and 1 patient visiting a medical center. 

The most incidents occurred on Fridays (5) with others occurring on Mondays (2), Thursdays (2), a Sunday (1), a Tuesday (1), and a Wednesday (1).

These incidents ended when: 

■ 5 shooters were apprehended by police at the scene (1 after 2 off-duty officers and a 

citizen restrained him, and 1 after a being restrained by an off-duty mall security officer);

■ 4 shooters committed suicide at the scene (3 before police arrived, 1 after); 

■ 2 shooters were killed by police at the scene; and

■ 1 shooter fled the scene and was apprehended by police at another location.

Schools

The 27 school incidents resulted in 57 individuals killed and 60 individuals wounded. In 

2 of the incidents, an adult fired on school board members during a board meeting. Of the 

remaining 25 incidents, 14 occurred in a high school (HS), 6 occurred in a middle school 

or junior high school (MS), 4 occurred in an elementary school (ES), and 1 occurred at a 

school including grades PreK-12. 

Where shootings occurred inside buildings, 14 (51.9%) took place in school classrooms 

and hallways (9 HS, 3 MS, 1 ES, 1 PreK-12), 3 in the school cafeteria (2 HS, 1 MS), 2 in 

school administrative offices, 2 in school board meeting rooms, and 2 in the school when no 

classes were in session. An additional 4 incidents were initiated outside (1 HS, 2 MS, 1 ES), 

including 2 where the shooters were in vehicles. 

In addition to the many student victims, the casualties included school employees, resulting 

in at least 14 killed (6 teachers, 5 five principals or assistant principals, and 3 other staff 

members) and another 16 wounded (9 teachers, 5 administrators, and 2 staff members).

In a majority of HS and MS incidents, the shooter was a student at the school; this was the 

case in 12 of 14 HS shootings and 5 of 6 MS shootings. Incidents at elementary schools did 

not involve the actions of a student. 

School Board Meetings

The 2 incidents at school board meetings resulted in 1 individual wounded. The shooters were 56- and 58-year-old males. One shooter committed suicide after an exchange of 

gunfire with the school district’s armed security guard, and the other shooter was arrested by 

police after other school administrators wrestled him to the ground.

Conclusion

The FBI initiated this study to add to the resources available to law enforcement and others 

who must consider their best course of action to prepare for, respond to, and recover from 

active shooter incidents. Using the same criteria over a 14-year span, the FBI sought to 

determine whether the number of active shooter incidents had changed, concluding the 

trend over the study period showed a steady rise. In the first half of the years studied, the 

average annual number of incidents was 6.4, but that average rose in the second half of the 

study to 16.4, an average of more than one incident per month. 

Of the 160 incidents studied, 64 (40.0%) would have met the criteria to fall under the 

federal statute passed in 2012 which defines mass killing as three or more killed in a single 

incident. Of the 64, 39 of these mass killings occurred within the final 7 years studied. 

Study results also indicate that, of the 11 defined location categories, the majority of 

incidents—45.6% of the 160—occurred in an environment related to commerce. The 

second most common incident locations were in educational environments (24.4%), and 

the study results established that some of these incidents involved some of the highest 

casualty numbers. 

Study results provided added clarity on instances where law enforcement appeared to be 

most at risk when responding to the scene. For example, though law enforcement responded 

to a large number of school incidents, no law enforcement officers were killed or wounded 

when responding to a school incident. However, in 45 of the 160 incidents where law 

enforcement did engage a shooter, law enforcement suffered casualties in 21 (46.7%) of the 

incidents, resulting in 9 officers killed and 28 wounded. 

Significantly, 10 of the officers were wounded in gunfights categorized as occurring in 

open spaces where the shooters were moving through streets and between buildings. 

In addition, 3 of the officers were wounded on military property, and another 3 were 

killed and 9 wounded in gunfights on other government properties. Based on these study 

results, therefore, the FBI will no longer use the term “confined” as part of the “active 

shooter” definition.

Though this study did not focus on the motivation of the shooters, the study did identify 

some shooter characteristics. In all but 2 of the incidents, the shooter chose to act alone. 

Only 6 female shooters were identified. Shooter ages as a whole showed no pattern. 

However, some patterns were seen in incident sub-groups. For example, 12 of 14 shooters 

in high school shootings were students at the schools, and 5 of the 6 shooters at middle 

schools were students at the schools. 

In addition, research results identified some location categories where victim targets were 

more readily identifiable, in part because of the shooters’ connections to the locations. For 

example, in businesses generally closed to pedestrian traffic, 22 of the 23 shooters were 

employees or former employees of the involved company. In other instances, the location 

category appeared less significant than the victims targeted. For example, in 15 (9.3%) 

of the 160 incidents, the shooter targeted family members. And in 15 (9.3%) of the 160 

incidents, the shooter targeted his current, estranged, or former spouse or his current or 

former girlfriend.

21

This study helps clarify the environment with regard to both the level of risk citizens face 

and the speed with which active shooter incidents occur. A majority of the 160 incidents (90 

[56.3%]) ended on the shooter’s initiative before the police arrived—sometimes when the 

shooter committed suicide or stopped shooting, and other times when the shooter fled the 

scene. In 64 incidents where the duration of the incident could be ascertained, 44 (69.0%) of 

64 incidents ended in 5 minutes or less, with 23 ending in 2 minutes or less.

The study identified 21 (13.1%) of 160 incidents where unarmed citizens made the selfless 

and deeply personal choices to face the danger of an active shooter. In those instances, 

the citizens safely and successfully disrupted the shootings. In 11 of those 21 incidents, 

unarmed principals, teachers, other school staff and students confronted the shooters to 

end the threat. In 10 incidents, citizens, working or shopping when the shootings began, 

successfully restrained shooters until police could arrive. And in 6 other incidents, armed 

off-duty police officers, citizens, and security guards risked their lives to successfully end 

the threat. These actions likely saved the lives of students and others present.

Recognizing the increased active shooter threat and the swiftness with which active shooter 

incidents unfold, these study results support the importance of training and exercises—

not only for law enforcement but also for citizens. It is important, too, that training and 

exercises include not only an understanding of the threats faced but also the risks and 

options available in active shooter incidents.

Finally, the FBI recognizes that seeking to avoid these tragedies is clearly the best result. The 

FBI remains dedicated to supporting prevention efforts within all communities affected by 

these tragedies. As the FBI continues to study the active shooter phenomenon, the Bureau 

remains committed to assist state, local, tribal, and campus law enforcement in developing 

better prevention, response, and recovery practices involving active shooter incidents.

Appendix B:

METHODOLOGY

The agreed upon definition of an active shooter by U.S. government agencies—including 

the White House, U.S. Department of Justice/FBI, U.S. Department of Education, and 

U.S. Department of Homeland Security/Federal Emergency Management Agency—is 

“an individual actively engaged in killing or attempting to kill people in a confined and 

populated area.”33 The FBI extends this definition to include individuals, because more 

than one shooter could be involved in some incidents. Implicit in the definition is that 

the subject’s criminal actions undertaken include the use of a firearm. Though the federal 

definition includes the word confined, the FBI excluded this word when considering active 

shooter incidents. This is because the term confined could be interpreted to omit incidents 

that occurred outside a building, when in actuality, many incidents originated outside or 

progressed from indoors to outdoors, or vice-versa, or occurred entirely along a route of 

travel or at various locations. 

The FBI developed discriminating factors to further differentiate potential active shooter 

incidents, considering for inclusion: 

■ Shootings in public places; 

■ Shootings occurring at more than one location;

■ Shootings where the shooters’ actions did not appear to be another criminal act; 

■ Shootings resulting in a mass killing;

■ Shootings indicating an apparent spontaneity by the shooter;

■ Shootings where the shooters appeared to methodically search for potential victims; or

■ Shootings that appeared focused on injury to people, not buildings or objects.

Because the risk to civilians in active shooter incidents appears to do with the apparent randomness of so many victims, for purposes of this study, an event was excluded if 

research established it involved primarily the following factors:

■ Conflicts arising from self-defense;

■ Gang violence;

■ Contained residential or domestic disputes; 

■ Controlled barricade/hostage situations;

■ Crossfire as a byproduct of another ongoing criminal act; or

■ Drug violence.

To evaluate appropriate incidents to include and exclude, the FBI reviewed published 

studies and research articles on actual shooting incidents or related research conducted by 

other government agencies, appointed gubernatorial panels, local advisory commissions, 

and other public and private entities.34 Using the federal definition of active shooter and the

that occurred during the 2000 to 2013 time span that might fit into this study. This set of 

incidents was gathered from FBI data as well as other previously published lists of shooting incidents, including a comprehensive list of incidents developed by the New York 

Police Department35 and one of the most comprehensive studies of shooting incidents in 

the United States to date—a study from 2000 to 2010 conducted by researchers from Texas 

State University (TXST) and its Advanced Law Enforcement Rapid Response Training 

(ALERRT) Center.36 The FBI collected further data from law enforcement reports and internal and open source information.37 A panel representing local law enforcement, the FBI, and 

TXST then used a deliberative process38 to identify the 160 active shooter incidents for this 

study. Researchers from TXST were consulted extensively throughout this analytical effort.

Appendix C

INCIDENT LOCATIONS

The FBI identified 11 incident location categories, seeking to identify the primary location 

where the public was most at risk during an incident. For example, in 9 incidents, casualties 

occurred inside a private residence before a shooter moved to a more public area. In those 

incidents, the public area was identified as the primary location. In addition, some specialized business locations (i.e., malls and health care facilities) were separately identified. 

DEFINITIONS OF LOCATION CATEGORIES: 

Malls—Types of businesses typically consisting of more than one anchor store and many 

smaller businesses under a single roof, though they may include some open spaces. Strip 

malls, which typically provide no indoor open spaces and are often arranged in a single row, 

are included in the business category.

Businesses Open to Pedestrian Traffic—Private properties with the primary function of 

making, buying, or selling goods or providing services in exchange for money where pedestrian traffic is anticipated on a daily basis. Examples include restaurants, bars, law firms, 

theaters, grocery stores, private civic organization spaces, and event venues. This category 

does not include locations otherwise defined more exclusively in another category, such as 

malls or health care facilities, and institutions of higher education. 

Businesses Closed to Pedestrian Traffic—Private properties primarily functioning in 

commerce without daily pedestrian traffic. Examples include manufacturing centers, 

packaging and distribution facilities and factories, warehouses, assembly plants, and 

commercial vehicle maintenance, storage, and repair facilities.

Schools—Public and private properties used for educating students from pre-kindergarten 

to 12th grade, as well as school administrative functions such as board and staff meetings.

Institutions of Higher Education—Public or private properties used for post-high 

school studies.

Other (Non-Military) Government Properties—Public properties owned by local, state, 

federal, or tribal governmental entities. Examples include courthouses, administrative 

buildings, and town halls. This category does not include locations otherwise defined more 

exclusively in another category such as military property or schools. 

Open Spaces—Public or private properties openly accessible to the public. Incidents are 

categorized as occurring in open space if they take place primarily in an open air location 

rather than beginning or ending inside a building. Examples include incidents where 

the shooter is inside a moving car and incidents where the shooter acts while walking or 

running through public streets, open parking lots, or parks. 

Military Properties—Public properties owned by the U.S. government and primarily 

reserved for the use of the U.S. military. Examples include military bases, airfields, sea 

ports, and training ranges.

Health Care Facilities—Public or private facilities that provide primary or secondary 

health services. Examples include hospitals, clinics, and urgent care, hospice care, and 

retirement facilities.

Houses of Worship—Public or private facilities used for religiously-sponsored activities 

at the time of an incident. This includes commercial properties used as houses of worship 

at the time of the incident. Examples include churches, temples, synagogues, mosques, and 

related religious gathering and retreat facilities. 

Residences—Public or private single or multi-family places of residence.
