FROELICH, J. 

{¶ 1} Traey Mobley appeals from a judgment of the Montgomery County Court of 

Common Pleas, which found him guilty, after a bench trial, of domestic violence and 

felonious assault; the court acquitted him of driving under the influence of drugs and/or 

alcohol. The trial court sentenced Mobley to three years in prison, and Mobley appeals. 
-2- 

For the following reasons, the trial court’s judgment will be affirmed. 

I. Factual and Procedural History 

{¶ 2} According to the State’s evidence at trial, on June 22, 2015, Mobley resided 

with his girlfriend, Latisha Walker, their daughter, and Walker’s mother in Miami 

Township. Their residence was on the west side of the street, which ran roughly northsouth, and the home’s attached garage and driveway were on the north end of the house. 

A tree was located to the north of the driveway between the driveway and a neighbor’s 

yard. The street had a narrow grassy area between the sidewalk and the roadway. 

{¶ 3} At approximately 2:00 a.m. that day (June 22), Walker’s mother was 

awakened by “banging” and “screeching” outside. She ran to the garage door, opened 

it, and saw Walker in her (Walker’s) red Dodge Charger, which was being pushed up 

against the garage by a silver Nissan Maxima driven by Mobley. (Walker owned both 

vehicles.) After opening the garage door, Walker’s mother saw the Maxima strike the 

Charger twice more. As a result of the collisions, there was extensive damage to the 

driver’s side of the Charger. Walker exited the Charger from the passenger side of the 

car. 

{¶ 4} Officer Shane Duffey of the Miami Township Police Department was on patrol 

in a marked cruiser, when he observed the Charger and the Maxima, both still running, 

and heard a man and two women yelling loudly outside the residence. Officer Duffey 

heard Walker’s mother ask Mobley, “Why didn’t you stop?” Duffey made contact with 

the individuals, who he learned were Mobley, Walker, and Walker’s mother. Duffey 

described Mobley as “somewhat cocky, relaxed, like it was just a simple accident.” 

Mobley claimed to Officer Duffey that he had lost control of his car, overcorrected, and 
-3- 

went onto the wet grass. 

{¶ 5} Duffey testified that he looked around the yard and saw a long trail of vehicle 

tracks coming from the neighbor’s yard to the south; those tracks crossed the driveway 

and went to the north neighbor’s yard. Duffey stated that the tracks did not line up with 

where the vehicles were found. Duffey further saw dirt “gouging off of the right of the 

driveway, almost into the neighbor’s yard to the north.” Duffey contacted additional 

officers for assistance. 

{¶ 6} Officer Shawn Todd, a traffic accident reconstructionist, was called to 

Mobley’s address. When Todd arrived, he saw the Maxima front end to front end with 

the Charger; Mobley, Walker, and Walker’s mother were still outside the home. Todd 

stated that he looked around the yard and tried to determine what had happened. Officer 

Todd looked for physical evidence at the scene, including “tire marks, debris, contact, and 

induced damage to vehicles,” and he later came back to the residence during daylight 

hours to review the scene. Officer Todd described the damage to the vehicles, tire 

marks, skid marks, yaw marks, and debris that he saw and explained how that evidence 

indicated what had occurred. 

{¶ 7} Officer Todd concluded that Mobley had hit the Charger three times with the 

Maxima. He stated that the evidence at the scene indicated that Mobley had driven from 

the south, jumped the curb on the west side of the street at an angle, crossed the sidewalk 

onto the grass in front of Mobley’s home, driven across the yard, and hit the driver’s side 

of the Charger on the driveway, causing the Charger to spin counter-clockwise until it was 

nearly parallel with the garage door. The Maxima accelerated as it continued across the 

driveway and around a tree on the north side of the driveway, and circled back onto the 
-4- 

street southbound. The Maxima continued to circle around, jumped the curb just south 

of the driveway, crossed the sidewalk, and again hit the driver’s side of the Charger on 

the driveway. Todd stated that the Maxima backed up and then came forward again on 

the grass to the south of the driveway, hitting the front of Charger. When asked on crossexamination if he and defense counsel could agree that there was an accident, Todd 

responded, “I can’t say this was an accident. This was an intentional act likely.” They 

did agree that the two cars had collided. 

{¶ 8} Officer Todd created three “sketches” (not to scale) depicting what he 

believed happened at the scene; those diagrams (Plaintiff’s Exs. 46-48) were admitted at 

trial, over Mobley’s objection.1

{¶ 9} Both cars were towed for evidence. Officer Duffey stated that the Maxima 

was able to be backed up and driven onto the flatbed tow truck. 

{¶ 10} Walker testified on Mobley’s behalf. She stated that she did not know 

whether Mobley was aware that she was in the Charger when he hit it with the Maxima, 

and that she did not believe that Mobley was trying to cause her physical harm. Walker 

stated that she was moving her car, too, and that the cars “hit each other together at the 

same time.” Walker testified that, after the collisions, Mobley “didn’t attack me,” he 

apologized, and he said that he would pay for the damage. Walker testified that, when 

she spoke with the police, an officer told her that she would go to jail if she did not say 

what had happened. Walker acknowledged on cross-examination that she had told an 

 

1 Mobley objected on the grounds that (1) the diagrams were not to scale, (2) they were 

“practically testimonial in nature” and “the best evidence rule would dictate that the 

testimony from the stand would be better than a document,” and (3) they were cumulative 

of Officer Todd’s testimony. (Trial Tr. at 79.) 
-5- 

officer that Walker had hit her car three times, that she “was afraid,” and that she believed 

at that time that Mobley was trying to hurt her. 

{¶ 11} When asked about the Maxima’s condition before the incident, Walker 

testified that that it was in “pretty good condition,” but needed brake pads. 

{¶ 12} Mobley also testified in his own defense. He stated that he did not know 

that Walker was in the Charger when they collided and that he did not try to cause her 

physical harm. Mobley testified that he lost control of the vehicle when he reached down 

to pick up his phone from the floor of the vehicle and texted Walker. He indicated that, 

when he looked up, he saw a PT Cruiser parked on the street, overcorrected, and went 

into the yard. 

{¶ 13} Mobley testified that Walker had “seen him coming” and had tried to move 

out of the way, but the vehicles collided. Mobley further stated that this collision 

“knocked the bumper loose from the Maxima, which got wedged into the wheel well. * * * 

I didn’t have any control of the wheel, which made me do, basically, a big donut around 

the tree. And we collided again at the front of the car.” Mobley also said that there were 

problems with the brakes, which prevented him from stopping. Mobley testified that he 

remembered two collisions, and he said a third contact was “from her trying to move the 

car as well.” 

{¶ 14} Mobley testified that he was not angry after the collisions, and that he 

approached Walker to check on her welfare. Mobley stated that he told the responding 

officer what had happened, but the officer “automatically just assumed that it was BS.” 

Mobley stated that he had not talked to Walker since the incident. 

{¶ 15} Officer Todd testified as a rebuttal witness. The State played a portion of 
-6- 

his cruiser video from that night, which showed the Maxima being driven and braking prior 

to being placed on a flatbed tow truck. Todd also testified that tire tracks were located 

on the opposite side of the street from the PT Cruiser, and he found nothing to indicate 

that it was necessary to avoid the PT Cruiser. Todd further testified that Mobley’s 

assertion that the bumper caused his wheel to lock up was inconsistent with the evidence 

at the scene, notably the acceleration marks by both tires in the grass north of the 

driveway and the yaw mark in the street. Finally, Todd stated that Mobley gave several 

explanations on June 22 for why he lost control, but Mobley never mentioned the PT 

Cruiser. 

{¶ 16} To rebut Mobley’s testimony that he had not had contact with Walker since 

the incident, the State offered jail telephone calls between Mobley and Walker. 

{¶ 17} The trial court found Mobley guilty of felonious assault and domestic 

violence, but not guilty of OVI. In reaching its decision, the trial court indicated that it 

“found the testimony of Officer Todd to be very credible and his reconstruction evidence 

to be most persuasive.” The court stated that it found Mobley’s testimony including ̶

his testimony about having no contact with Walker since the incident, the Maxima’s having 

braking problems, and the circumstances of the collision ̶ to be “incredible.” 

{¶ 18} After a presentence investigation, the trial court sentenced Mobley to three 

years in prison. Mobley appeals from his conviction, challenging the admission of Officer 

Todd’s testimony. 

II. Admission of Police Officer’s Accident Reconstruction Testimony 

{¶ 19} Mobley’s sole assignment of error states: 

The Trial Court Erred to the Prejudice of Mr. Mobley When It Permitted the 
-7- 

State to Introduce Testimony of Its Accident-Reconstruction Expert Despite 

Failing to Provide the Expert’s Report and Qualifications to Mr. Mobley. 

{¶ 20} On appeal, Mobley claims that the State improperly presented expert 

testimony by Officer Todd without notifying him that Todd would be providing expert 

testimony and without providing an expert report. Mobley asserts that Officer Todd’s 

testimony should have been excluded under Crim.R. 16(K), and that he suffered prejudice 

as a result of the admission of that testimony. 

{¶ 21} Crim.R. 16(A) creates a reciprocal duty that the defense and prosecution 

disclose certain information covered by the Rule. Crim.R. 16(B)(6) requires the 

disclosure of “[a]ll reports from peace officers, the Ohio State Highway Patrol, and federal 

law enforcement agents.” 

{¶ 22} Crim.R. 16(K), concerning expert witnesses, provides: 

An expert witness for either side shall prepare a written report summarizing 

the expert witness’s testimony, findings, analysis, conclusions, or opinion, 

and shall include a summary of the expert’s qualifications. The written 

report and summary of qualifications shall be subject to disclosure under 

this rule no later than twenty-one days prior to trial, which period may be 

modified by the court for good cause shown, which does not prejudice any 

other party. Failure to disclose the written report to opposing counsel shall 

preclude the expert’s testimony at trial. 

The purpose of Crim.R. 16(K) is to avoid unfair surprise by providing notice to the 

opposing party and allowing that party an opportunity to challenge the expert’s findings, 

analysis, or qualifications, possibly with the support of an adverse expert who could 
-8- 

discredit the opinion after carefully reviewing the written report. State v. Fetty, 11th Dist. 

Portage No. 2011-P-0091, 2012-Ohio-6127, ¶ 36. 

{¶ 23} The trial court has discretion to regulate discovery in a manner consistent 

with Crim.R. 16. If it comes to the court’s attention that a party has not complied with 

Crim.R. 16, the trial court may “order such party to permit the discovery or inspection, 

grant a continuance, or prohibit the party from introducing in evidence the material not 

disclosed, or it may make such other order as it deems just under the circumstances.” 

Crim.R. 16(L)(1). 

{¶ 24} Mobley argues that the State never indicated, prior to trial, that Officer Todd 

would testify as an expert and that the State failed to provide an expert’s report, as 

required by Crim.R. 16(K). The record is unclear whether this was the case. 

{¶ 25} The record contains several receipts indicating that certain items were 

disclosed pursuant to Crim.R. 16. On August 11, 2015, the State filed a receipt indicating 

that the State had provided Mobley a copy of his computerized criminal history, pursuant 

to Crim.R. 16(B)(2). On August 24, the State filed a Receipt for Non-Electronic 

Supplemental Discovery, stating that the defense had been provided two DVDs 

containing recorded cruiser camera footage from June 22, 2015. One week later, on 

August 31, 2015, the State filed an additional Receipt for Non-Electronic Supplemental 

Discovery, stating that the State had provided the defense with one DVD containing 

recorded cruiser camera footage from June 22, 2015 (Officer Duffey’s cruiser) and an 

Incident History Detail #51730109 (one page). 

{¶ 26} However, other evidence was presented at trial that was not referenced by 

discovery receipts. For example, at trial, the State offered, without objection, 42 
-9- 

photographs taken of the evidence at Mobley’s residence and of the vehicles involved in 

the collisions. Photographs generally must be disclosed pursuant to Crim.R. 16(B)(3). 

In addition, during cross-examination of Walker’s mother, defense counsel asked her 

about a written statement that she had given to the police on June 22, 2015; the written 

statement is part of the record as Defendant’s Exhibit A (not admitted into evidence). 

Written statements by a witness in the State’s case-in-chief must be disclosed pursuant 

to Crim.R. 16(B)(7). The State also presented several recorded jail telephone calls in its 

rebuttal case; recorded statements of a defendant are governed by Crim.R. 16(B)(1). It 

is apparent that Mobley received Walker’s mother’s written statement, considering that it 

was used by the defense at trial, and the photographs and jail telephone recordings were 

admitted without objection. 

{¶ 27} Mobley did assert in his sentencing memorandum and motion for an appeal 

bond that it was unknown whether Todd had the credentials to be designated an expert 

“as the defense was never given the opportunity to voir dire the officer, as he was not 

testifying as an expert.” Mobley asserted that he would have had his own expert, but did 

not obtain one because he never received a curriculum vitae from the State and no 

witness list with an expert designation was filed. 

{¶ 28} From the record before us, we can only speculate whether Mobley received, 

prior to trial, copies of Officer Todd’s “sketches” of the vehicle dynamics and the evidence 

at the scene or any other police report by Todd. The record does not reflect whether 

Mobley was or was not notified about the nature of Todd’s testimony. Mobley complains 

that Officer Todd was not identified as an expert witness on the State’s witness list, filed 

on August 23, 2015, but Crim.R. 16(I) does not require the witness list to identify the 
-10-

substance of a witness’s testimony. 

{¶ 29} Significantly, Mobley did not object to Officer Todd’s testimony at trial, and 

he did not seek a continuance or make any other motion on the ground that the State had 

failed to provide an expert report and a summary of Todd’s qualifications prior to trial. 

Consequently, we review the admission of Officer Todd’s testimony for plain error.

{¶ 30} In order to constitute plain error, the error must be an obvious defect in the 

trial proceedings, and the error must have affected substantial rights. State v. Norris, 2d 

Dist. Montgomery No. 26147, 2015-Ohio-624, ¶ 22; Crim.R. 52(B). The Ohio Supreme 

Court has recently reiterated that, even if an accused shows that the trial court committed 

plain error affecting the outcome of the proceeding, an appellate court is not required to 

correct it. State v. Rogers, 143 Ohio St.3d 385, 2015-Ohio-2459, 38 N.E.3d 860, ¶ 23. 

Rather, plain error should be noticed “with the utmost caution, under exceptional 

circumstances and only to prevent a manifest miscarriage of justice.” (Emphasis added 

in Rogers). Id., quoting State v. Long, 53 Ohio St.2d 91, 372 N.E.2d 804 (1978), 

paragraph three of the syllabus. 

{¶ 31} A police officer does not need to be an expert to testify about the collection 

of data and recording of information at an accident scene, but accident reconstruction 

“involves the use of scientific methodology to draw inferences from investigative data.” 

State v. Brady, 7th Dist. Mahoning No. 13 MA 88, 2014-Ohio-5721, ¶ 43. See Roy v. 

Gray, 197 Ohio App.3d 375, 2011-Ohio-6768, 967 N.E.2d 800, ¶ 11 (1st Dist.). 

Consequently, a police officer who testifies about the cause of an accident must have 

knowledge concerning or experience in determining the cause of accidents. Brady at ¶ 

43. 
-11-

{¶ 32} At the beginning of his testimony, Officer Todd stated that he had 

specialized in traffic accident reconstruction since 2007 or 2008. He studied in the areas 

of vehicle dynamics, crush analysis, energy and crush, and basic traffic accident 

reconstruction measurements. His training included basic accident investigation during 

the academy, level one traffic accident investigation, level two traffic accident 

investigation, vehicle dynamics and traffic accident reconstruction, and black box 

downloading. Todd stated that he is part of the Miami Township technical accident 

investigation team, and he routinely is called for serious vehicle crashes and fatal traffic 

crashes. 

{¶ 33} Officer Todd testified not only about the evidence at the scene, but also 

provided his opinion on what had occurred based on that evidence. For example, in 

concluding that the first impact caused the Charger to rotate counterclockwise and slide 

off the driveway into the grass, Todd explained that there were tire marks indicating a 

sideways slide, evidence in the grass consisting of ripped turf grass and mounded up dirt, 

and caked dirt in the rim and tire area on the passenger rear tire of the Charger. Officer 

Todd also stated that he could see “contact and induced damage on the body panel that 

would indicate that this vehicle [the Charger], upon being impacted, was rotated 

counterclockwise, which is evidenced by the crush on the vehicle and the stretching and 

tearing of the metal.” 

{¶ 34} At no point during the trial did Mobley make the trial court aware Officer 

Todd’s opinion testimony may be improper. Mobley did not raise, either prior to or during 

the trial, any alleged failure by the State to comply with Crim.R. 16(K). Mobley did not 

object to or move to strike Officer Todd’s testimony on the ground that his qualifications 
-12-

were insufficient to permit him to render opinions on the number of collisions and how 

they occurred. Mobley did not ask to voir dire Officer Todd regarding his qualifications. 

Nor did Mobley raise with the trial court that Officer Todd had not been recognized by the 

court as an expert in accident reconstruction. In the absence of any objection to Todd’s 

competence to testify as an expert under Evid.R. 702 or of any other objection or motion 

based on the State’s alleged failure to comply with Crim.R. 16(K), the trial court had no 

reason to know of any potential basis to exclude Todd’s testimony due to a Crim.R. 16(K) 

violation. The trial court cannot be faulted for failing to exclude, sua sponte, evidence 

that, on its face, appeared to be proper. We find no plain error in the trial court’s 

admission of Officer Todd’s testimony. 

{¶ 35} Additionally, the record does not indicate that defense counsel would have 

tried the matter differently had he been aware of Officer Todd’s opinions. Defense 

counsel’s strategy was not to deny that Mobley had struck the Charger. Rather, defense 

counsel asserted that Mobley did not have the requisite intent to convict him of felonious 

assault and domestic violence. As counsel stated during closing arguments: 

* * * Your Honor, what this case boils down to is the mens rea. And 

we have the speculation of the State's witness based on his training and 

experience, what he thinks may have happened based on mud tracks and 

grass and dents and bangs. And then we have the testimony of the live 

witnesses which were present during the event. 

And Ms. Walker, although she didn't want to be part of this, came in 

the courtroom and specifically said that she did not think that my client 

would try to hurt her or would attempt to try to hurt her. And my client 
-13-

testified that he would not do -- not hurt her or attempt to hurt her. And in 

fact, he didn’t even know, his testimony was, that she was in the vehicle. 

She didn’t know whether he knew he (sic) was in the vehicle. The police 

officers never asked whether he knew she was in the vehicle. So what we 

have -- the resultant is my client did not even know that she was in the 

vehicle at this time. So to -- the question is how could he knowingly cause 

or intentionally cause -- or attempt to cause physical harm to another when 

the evidence doesn’t flesh out or pan out that there was even another 

present that he knew of or that anybody knew of. Nobody knew she was 

in the car. There was no testimony as to that. 

It doesn't make sense that he knew she was in the vehicle. We 

didn’t have a case here today where we talked about the parties were in a 

fight, that they got into an argument, that they were bickering, that they were 

on bad terms with each other, or that that was the motive for his vendetta 

to go back and crash a car. There was no discord or disharmony 

throughout this case. There was no testimony at all. He was on his home 

[sic]. The testimony was that he lost control of the vehicle and hit the other 

vehicle, and then they became entangled. And she moved, according to 

her testimony, Latisha Walker, and he moved, according to his testimony, 

back around the tree. And we have marks and scrapes and breaks and all 

those other indicia of an automobile accident. There’s no doubt that an 

automobile accident happened. The issue is whether he was intentionally 

or knowingly causing or attempting to cause physical harm to another. 
-14-

And the same argument goes for the second count in the indictment, 

which is a domestic relation [sic]. And that is that the State needs to prove 

that my client intentionally, knowingly caused or attempted to cause 

physical harm to a family or household member. And I just would submit 

to the Court that the State has not proven or brought forth proof that there 

was any intentional act or knowing act on my client. Now if the statute read 

that Tracey Mobley (sic) recklessly caused or attempted to cause physical 

harm by the way he was driving, you know, we’d have a different case. 

Maybe that was reckless. But I do not think it rises to the level of 

intentional. And I do not think the State met its burden with respect to 

intentional. And I think that that is the piece de resistance, the ultimate 

question of this case. All the other issues, whether there was a car 

accident, whether they crashed, that’s not disputed. So I’d ask the Court 

to look closely at that burden that the State has of proving beyond a 

reasonable doubt that my client knowingly, intentionally, based on the live 

testimony of my client and the complainant. 

(Trial Tr. at 128-130.) 

{¶ 36} Defense counsel made no indication during the trial that he was surprised 

by Officer Todd’s testimony, that he needed more information about Officer Todd’s 

qualifications, or that he would have obtained his own accident reconstruction expert had 

he been aware of Todd’s opinions prior to trial. Mobley did not ask for a continuance so 

that he could obtain his own expert, in light of the State’s alleged failure to provide an 

expert report pursuant to Crim.R. 16(K). From the record before us, we cannot conclude 
-15-

that the State improperly presented expert testimony by Officer Todd, that Officer Todd’s 

testimony was improperly admitted by the trial court, or that Mobley was unduly prejudiced 

as a result of the admission of Todd’s testimony. 

{¶ 37} Mobley’s assignment of error is overruled. 

III. Sufficiency of the Evidence 

{¶ 38} As an additional matter, Mobley claims that, in the absence of Officer Todd’s 

testimony, the State lacked sufficient evidence. “A sufficiency of the evidence argument 

disputes whether the State has presented adequate evidence on each element of the 

offense to allow the case to go to the jury or sustain the verdict as a matter of law.” State 

v. Wilson, 2d Dist. Montgomery No. 22581, 2009-Ohio-525, ¶ 10, citing State v. 

Thompkins, 78 Ohio St.3d 380, 386, 678 N.E.2d 541 (1997). 

{¶ 39} Even if we were to agree that Officer Todd’s testimony was not properly 

admitted, the Supreme Court of Ohio has rejected the position that a reviewing court 

should consider only properly admitted evidence to determine whether the State has 

presented sufficient evidence to support a conviction. State v. Brewer, 121 Ohio St.3d 

202, 2009-Ohio-593, 903 N.E.2d 284, citing Lockhart v. Nelson, 488 U.S. 33, 38, 109 

S.Ct. 285, 102 L.Ed.2d 265 (1988); State v. Renner, 2d Dist. Montgomery No. 25514, 

2013-Ohio-5463, ¶ 8. Contrast State v. Kareski, 137 Ohio St.3d 92, 2013-Ohio-4008, 

998 N.E.2d 410 (appellate court should not consider judicially-noticed fact when reviewing 

sufficiency of the evidence). In reviewing the sufficiency of the evidence, we must 

consider all of the evidence admitted at trial, even improperly admitted evidence. 

Brewer; State v. Stokes, 2d Dist. Champaign No. 2015-CA-22, 2016-Ohio-612, ¶ 8, fn.3. 

{¶ 40} Mobley does not claim that, when all of the evidence is considered, the 
-16-

State presented insufficient evidence at trial; rather, he argues that the State’s case, 

without Todd’s testimony, would be insufficient to support his conviction. Upon review 

of the record, we find sufficient evidence to support Mobley’s convictions for domestic 

violence and felonious assault. Accordingly, Mobley’s claim that his conviction was 

based on insufficient evidence is without merit. 

III. Conclusion 

{¶ 41} The trial court’s judgment will be affirmed.
