HALL, J.

{¶ 1} Ryan D. Mitchell appeals from his conviction and sentence on charges of

felony murder, grand theft, assault on a police officer, having a weapon while under
 -2-

disability, and a firearm specification.1

{¶ 2} Mitchell advances three assignments of error. First, he contends the jury’s

verdict is against the manifest weight of the evidence. Second, he claims the trial court

erred in instructing the jury, thereby violating his due-process rights. Third, he raises a

claim of ineffective assistance of counsel.

{¶ 3} The present appeal stems from Mitchell’s execution-style murder of his

girlfriend, Melissa Nilson, in February 2014. The State’s evidence at trial established that,

following a dispute, Mitchell shot Nilson in the head at point-blank range while she was

on her knees in the front yard of her home begging for her life with her hands in the air.

After briefly walking away from Nilson’s body, Mitchell went inside her home and retrieved

her car keys. He then sped away as police sirens could be heard approaching the scene.

While fleeing from police at a high rate of speed, Mitchell crashed Nilson’s car. A foot

chase ensued, and police eventually apprehended him in the kitchen area of a business

known as Jackass Flats in Huber Heights.

{¶ 4} At trial, Mitchell did not seriously dispute committing the offenses at issue.

Rather, the defense strategy was that he was not guilty by reason of insanity (NGRI). The

record contains evidence that Mitchell repeatedly yelled at Nilson’s lifeless body to “get

up” after shooting her. He also was overheard making bizarre statements after the

shooting. When police encountered Mitchell at Jackass Flats, he yelled that they were in

the house of God and exclaimed that he was going to send the officers to Heaven. While

wrestling with police, he was heard saying, “Strip me of these tattoos,” “Grandma is in

1 Mitchell also was found guilty of numerous other offenses that merged into those set
forth above for purposes of sentencing.
 -3-

here,” and “Where’s Dave?” Once outside the business, he repeated rap lyrics and

referred to zombies. A police officer also overheard him saying, “Tickle me again” and

“This is a video game.”

{¶ 5} Mitchell’s friends and family members testified about his strange behavior

prior to the shooting. His brother, Robert, testified that Mitchell had reported hearing

things and had expressed a belief that he was being watched and listened to by

televisions and phones. Robert also recalled Mitchell saying Nilson’s house was demon

possessed. Mitchell’s grandmother, Miriam, testified that Mitchell had mentioned aliens

being everywhere listening to his conversations. She also mentioned Mitchell being

obsessed with paranoid delusions, including a belief that Nilson’s house was full of

demons and that Nilson was the Devil. Family friend Freeda Hartly recalled Mitchell being

frantic about demons, aliens, and other paranoid ideations. Mitchell’s nephew, Vincent,

testified that Mitchell believed aliens were coming to get them and that they needed to

flee to a mountain in Kentucky. Mitchell’s father, David, testified that Mitchell believed he

lived in a demon-possessed home. After being booked into jail, Mitchell received the anti-

psychotic drugs Haldol and Zyprexa, along with the anti-anxiety drug Ativan. He later was

given the anti-depressant Trazodone and anti-psychotic drug Rispersal. He also received

another drug, Cogentin, to address the side effects of the other drugs.

{¶ 6} With regard to Mitchell’s NGRI defense, the record contains testimony from

three expert witnesses who examined him in jail. The first expert, psychologist Barbara

Bergman, testified as a defense witness. She concluded that Mitchell “was suffering from

a severe mental illness” when he shot Nilson. (Trial Tr. at 573). Specifically, she

diagnosed “schizoaffective disorder bipolar type” with an “acute manic episode.” (Id.).
 -4-

Bergman also opined that as a result of his severe mental illness Mitchell was unable to

determine whether his actions were right or wrong. (Id. at 577, 652).

{¶ 7} The second expert, psychologist Thomas Martin, testified as a prosecution

witness. He testified about his administration of an “SIRS” test to Mitchell. Seven out of

eight of Mitchell’s scores on the test fell into the “probable feigning” category, which

suggested that Mitchell was exaggerating his symptoms of mental illness. (Id. at 748).

Martin stated that Mitchell’s combination of scores on the SIRS test was “generally not

found in a clinical population of genuinely psychotic individuals.” (Id.) Nevertheless, based

on all of the information he possessed, Martin concluded that Mitchell was suffering from

a non-specified mental disease or defect when he committed the crimes at issue. (Id. at

786, 816-817). Martin also concluded, however, that Mitchell knew the wrongfulness of

his actions when he committed the offenses. (Id. at 786-787, 800, 802, 821-826).

{¶ 8} The third expert, psychologist Massimo De Marchis, also testified as a

prosecution witness. Unlike the other two experts, De Marchis diagnosed Mitchell as

having a “paranoid personality” and an “antisocial personality disorder.” (Id. at 872). He

explained, however, that these were “character disorders” as opposed to “psychotic

disorders.” (Id. at 873, 897). De Marchis also testified about his administration of an

“MMPI” test to Mitchell. He concluded that Mitchell’s test results were invalid. This was so

because Mitchell “endorsed virtually every item of the test that would have been

consistent with mental illness.” (Id. at 877). According to De Marchis, the test results

established that Mitchell was malingering and “purposefully trying to look like he suffered

from a serious mental illness.” (Id.). De Marchis opined that when Mitchell killed Nilson

“his actions were deliberate and not in response to any perceived threats triggered by
 -5-

paranoid or delusional ideation.” (Id. at 895). Although De Marchis did not believe Mitchell

was suffering from any true psychosis that would qualify as a mental disease or defect at

the time in question, he opined that Mitchell’s reported symptoms, if they really existed,

were “more similar to a drug induced psychosis than to anything else.” (Id. at 929, 935).

In any event, De Marchis concluded that Mitchell knew the wrongfulness of his actions at

the time of his offenses. (Id. at 898-899, 962).

{¶ 9} The jury ultimately rejected Mitchell’s insanity defense, and he was convicted

and sentenced on the charges set forth above.2 The trial court imposed an aggregate

sentence of 22.5 years to life in prison. This appeal followed.

{¶ 10} In his first assignment of error, Mitchell contends the jury’s rejection of his

NGRI defense is against the manifest weight of the evidence. He asserts that the record

lacks “substantial evidence” on which the jury could have relied to find that he knew the

wrongfulness of his actions. In particular, he argues that psychologist Bergman “was

consistent and unchallenged during cross-examination concerning her conclusion that

[he] did not know the wrongfulness of his actions based on suffering from a severe mental

illness.” (Appellant’s brief at 10). Although psychologists Martin and De Marchis disagreed

with Bergman as to whether Mitchell knew the wrongfulness of his actions, Mitchell

contends the evidence on that issue was “far from substantial,” “conflicting,” and

“uncertain.” (Id.). Noting that he was only required to establish his insanity defense by the

preponderance of the evidence, Mitchell urges us to “exercise [our] authority and remand

this case for a new trial.” (Id.).

2 Parenthetically, we note that the weapons-under-disability offense was tried
separately to the trial court, which found him guilty.
 -6-

{¶ 11} When a conviction is challenged on appeal as being against the weight of

the evidence, an appellate court must review the entire record, weigh the evidence and

all reasonable inferences, consider witness credibility, and determine whether, in

resolving conflicts in the evidence, the trier of fact “clearly lost its way and created such

a manifest miscarriage of justice that the conviction must be reversed and a new trial

ordered.” State v. Thompkins, 78 Ohio St.3d 380, 387, 678 N.E.2d 541 (1997). A

judgment should be reversed as being against the manifest weight of the evidence “only

in the exceptional case in which the evidence weighs heavily against the conviction.”

State v. Martin, 20 Ohio App.3d 172, 175, 485 N.E.2d 717 (1st Dist.1983).

{¶ 12} The credibility of the witnesses and the weight to be given to their testimony

primarily are matters for the trier of fact to resolve. State v. DeHass, 10 Ohio St.2d 230,

231, 227 N.E.2d 212 (1967). “Because the factfinder * * * has the opportunity to see and

hear the witnesses, the cautious exercise of the discretionary power of a court of appeals

to find that a judgment is against the manifest weight of the evidence requires that

substantial deference be extended to the factfinder’s determinations of credibility. The

decision whether, and to what extent, to credit the testimony of particular witnesses is

within the peculiar competence of the factfinder, who has seen and heard the witness.”

State v. Lawson, 2d Dist. Montgomery No. 16288, 1997 WL 476684 (Aug. 22, 1997). This

court will not substitute its judgment for that of the trier of facts on the issue of witness

credibility unless it is apparent that the trier of fact lost its way in arriving at its verdict.

State v. Bradley, 2d Dist. Champaign No. 97-CA-03, 1997 WL 691510 (Oct. 24, 1997).

{¶ 13} With the foregoing standards in mind, we conclude that the jury’s rejection

of Mitchell’s NGRI defense is not against the weight of the evidence. In reaching this
 -7-

conclusion, we recognize that Mitchell was only required to establish that affirmative

defense by the preponderance of the evidence. State v. Saini, 2d Dist. Greene No. 2013

CA 36, 2014-Ohio-5582, ¶ 30. “A person is not guilty by reason of insanity only if he

proves * * * that at the time of the commission of the offense, the person did not know, as

a result of a severe mental disease or defect, the wrongfulness of the person’s acts.” Id.

citing R.C. 2901.01(A)(14).

{¶ 14} Here the jury did not lose its way in finding that Mitchell failed to establish

his NGRI defense by the preponderance of the evidence. Although two of the three expert

witnesses concluded that Mitchell suffered from a severe mental disease or defect at the

time of his offenses, only psychologist Bergman opined that, as a result, he did not know

the wrongfulness of his actions. Having reviewed Bergman’s testimony, we note that little

of it addressed why she reached that conclusion. After opining at length about the

existence of a severe mental illness, defense counsel asked whether Mitchell was able

to determine the wrongfulness of his conduct. Bergman responded that, in her opinion,

“mania took over” and that “because of the acute manic episode, he was not thinking

rationally, he was not making rational choices with decisions.” (Trial Tr. at 577). Strictly

speaking, this response does not establish that Mitchell failed to know the wrongfulness

of his conduct. Pointing out that Mitchell was experiencing a manic episode and was not

thinking “rationally” does not directly address whether he appreciated the wrongfulness

of his conduct. In any event, on re-direct examination Bergman did confirm, albeit without

any elaboration, her belief that Mitchell was unable to determine whether his actions were

right or wrong. (Id. at 652).

{¶ 15} In their subsequent testimony, psychologists Martin and De Marchis
 -8-

disagreed with Bergman’s conclusion that Mitchell failed to know the wrongfulness of his

actions. In support of his conclusion, Martin relied largely on Mitchell’s responses to

questions when Martin interviewed him in jail. When Martin inquired about events leading

up to the shooting, Mitchell recalled that he had become angry with Nilson inside her

home when he discovered that she was using her cell phone to obtain drugs. (Id. at 778).

According to Martin, Mitchell stated: “ ‘I knew it was wrong to yell at her because I was

scaring her * * *.’ ” (Id.). After feeling threatened by Nilson, Mitchell retrieved a handgun

from a cabinet and pointed it at her. According to Martin, Mitchell recalled that he “ ‘knew

it was wrong’ ” to point the gun at Nilson but he “ ‘was still mad.’ ” (Id. at 780). Mitchell

then forced Nilson out the front door and into the yard at gunpoint. (Id.). With regard to

the shooting, Mitchell claimed he “ ‘didn’t know the gun was loaded.’ ” (Id. at 781). He

admitted to Martin, however, that he fled in Nilson’s car because he “ ‘just wanted to get

out of there’ ” and “ ‘thought the police would come and arrest [him] for killing [Nilson][.]’ ”

(Id. at 782). Mitchell added that he attempted to evade the police because he “ ‘figured

they were going to [Nilson’s] house to see what happened[.]’ ” (Id.). According to Martin,

Mitchell added: “ ‘I knew I was in trouble. I knew the police were after me about Melissa

and I had to get away.’ ” (Id. at 783). Mitchell also “ ‘knew it was wrong’ ” to fight with the

police when they apprehended him but felt like he “ ‘had to defend’ ” himself. (Id.). In

Martin’s opinion, Mitchell’s account of the events indicated that he knew the wrongfulness

of his actions at the time of his offenses. (Id. at 786, 800-802, 823).

{¶ 16} Psychologist De Marchis reached the same conclusion based on Mitchell’s

actions at the time of his offenses. (Id. at 962). He explained:

How can we determine if someone has [knowledge that what he is
 -9-

doing is wrong]? Well, by the description of their actions and behaviors on

or about at the time, especially at the time of the offense. So, let’s say that

somebody believed that so and so was the devil and they killed the devil.

Why would they run away from the scene? They did something that most

people would applaud.

Well, in this case absolutely not. He shot someone who was

defenseless at that point, fled the scene, tried to avoid apprehension as he

was being pursued, and further fought with the officers once they got to it.

All of those behaviors are not indicative of a mental illness. They’re

indicative of someone who knows that something is wrong and wants to

avoid apprehension and possibly avoid the consequences of the behavior.

(Id. at 898-899).

{¶ 17} On cross examination, De Marchis further explained:

* * * So a lot of people, who make [sic] commit crimes, may say—

may claim that they had some hallucinations that told them to do that, or the

devil made me do it, or whatever; in reality it’s their own thoughts, their own

fantasies, and then acting on them or refraining from them. And even if

someone heard those voices, those voices would not necessarily lead an

individual to actually comply with whatever the voices told them to do. You

can still exercise restraint and know right from wrong in spite, even in spite

of a command type hallucination that tells you, “ ‘Kill your brother.’ ”

***

What I have is objective psychological testing that is telling me that
 -10-

[Mitchell] is way exaggerating whatever symptomology there might be

there. So, in other words, as an examiner, I cannot take everything at face

value; I have to take it with a grain of salt, and especially if I have collateral

information describing the actions, and especially if I’m able to determine

that there were, the actions were purposeful and goal directed, then I have

to come to the conclusion that the individual in spite of whatever might have

been going on; in spite of paranoia and delusions, knew the wrongfulness

of their actions at the time of the offenses.

(Id. at 932-933).

{¶ 18} Finally, De Marchis engaged in the following discussion with the prosecutor

on re-direct examination:

Q. Okay. Well, and let me ask you this, do you have—did you come to a

different conclusion then [sic] Dr. Martin as to the Defendant’s knowing the

wrongfulness of his behavior at the time?

A. I did not come to a different conclusion. I mean, we both came to the

conclusion that he did know the wrongfulness of his actions at the time of

the offense. And this is in spite of whether or not he suffered from psychosis

or schizophrenia, or a character disorder, or a drug induced psychosis,

irrelevant of those diagnoses, the central issue is knowledge of the

wrongfulness of the action at the time of the offense, and we concluded that

he had that knowledge, and his actions demonstrated that at the time he

did have that knowledge.

Q. Okay.
 -11-

A. That was our conclusion.

***

Q. You also mentioned something about goal-direct, purposeful goal-

directed actions that addressed the Defendant’s knowledge of the

wrongfulness of his behavior. What were those in this case for you?

A. Well, chasing after the victim, who is fleeing the house, ignoring her

pleas, standing over her, and pulling the trigger, and calling her a stupid

bitch while you do that. I’m not sure there’s any psychosis that would

manifest itself in such a way. It’s a lot more consistent with rage and anger.

After the shooting—okay, he might have paced back and forth, perhaps

realizing the magnet [sic] of what he did.

Q. Uh-huh.

A. He might have called her name, wishing perhaps that he had not killed

her. But then he went in the house, grabbed the car keys, got in the car and

fled the scene. Is that purposeful behavior? Well, of course it is. Assuming

that you’re in the midst of a psychotic episode, you just shot someone, why

would you leave the scene?

Q. Uh-huh.

A. So being chased then after the accident by the police officer and pointing

your fingers at them as if you’re holding a gun, and ignoring the—again,

you’re fleeing and eluding.

Q. Uh-huh.

A. Again, that’s purposeful, goal-directed behavior; goal-directed, trying to
 -12-

avoid apprehension. So when you are engaging in such behaviors, it’s

understood that you know the wrongfulness of your actions.

(Id. at 962-964).

{¶ 19} After examining the competing expert testimony, we conclude that the jury

did not lose its way in apparently choosing to credit the testimony of Martin and De

Marchis over the testimony of Bergman as to whether Mitchell knew the wrongfulness of

his actions. As set forth above, Martin relied largely on Mitchell’s admissions during an

interview that he knew what he was doing was wrong at the time of his offenses. De

Marchis relied largely on Mitchell’s actions at the time of the offenses to infer that he knew

what he was doing was wrong. The record contains ample evidence supporting both

experts’ conclusions. This is not an exceptional case where the evidence weighs heavily

against the jury’s rejection of Mitchell’s NGRI defense. Accordingly, the first assignment

of error is overruled.

{¶ 20} In his second assignment of error, Mitchell argues that the trial court erred

in instructing the jury, thereby violating his due-process rights. He raises two specific

issues. First, he contends the trial court erred in rejecting his request for an instruction

regarding the role that drug usage and intoxication may play in the NGRI determination.

Second, he claims the trial court incorrectly worded an instruction it gave concerning a

defendant’s inability to refrain from doing his acts.

{¶ 21} With regard to the former issue, Mitchell requested the following instruction

found in Section 421.27 of the Ohio Jury Instructions: “Voluntary intoxication, no matter

how extreme, is not an insane condition. However, a defect or disease of the mind caused

by the use of (intoxicants) (drugs) and resulting in insanity, as previously defined, is a
 -13-

defense to an offense.” Mitchell argued to the trial court that the second sentence in

particular was pertinent in this case. (Trial Tr. at 988). The trial court refused to give the

instruction for two reasons. First, it found no evidence of intoxication. Second, with regard

to drug use causing a defect or disease of the mind, the trial court reasoned: “[T]he Court

holds [that] was not testified to by the necessary expert burden to indicate that that was

anything more than a possibility in this case, not even a probability which is the State’s

only burden. So we’re going to exclude that.” (Id. at 988-989).

{¶ 22} We note that “[r]equested jury instructions should ordinarily be given if they

are correct statements of law, if they are applicable to the facts in the case, and if

reasonable minds might reach the conclusion sought by the requested instruction. * * *

An appellate court reviews a trial court’s refusal to give a requested jury instruction for

abuse of discretion.” (Citations omitted.) State v. Adams, 144 Ohio St. 3d 429, 2015-

Ohio-3954, 45 N.E.3d 127, ¶ 240.

{¶ 23} We see no abuse of discretion here. Based on the evidence before it, the

trial court reasonably concluded that the requested instruction was unwarranted. As for

intoxication, the record reflects that Mitchell regularly consumed some alcohol. (Trial Tr.

at 894). He had not consumed any alcohol, however, on the day in question. (Id. at 665,

894, 923). The trial court also acted within its discretion in finding insufficient evidence to

justify an instruction about drugs causing a disease or defect of the mind. Although

Mitchell had a history of drug use and abuse, the only drug detected in his system upon

his arrest was a trace of Xanax, a benzodiazepine. (Id. at 925). More importantly, none

of the three psychological experts opined that Mitchell had a disease or defect of the mind

caused by the use of drugs. Bergman testified Mitchell did have a mental disease or
 -14-

defect, namely “schizoaffective disorder bipolar type” with an “acute manic episode.” (Id.

at 573). She never suggested, however, that his psychosis was drug-induced. To the

contrary, she explained: “[W]hen someone is experiencing a drug-induced psychotic

episode once the body metabolizes the drug usually the symptoms begin to subside. But

that was not, that was not what was happening.” (Id. at 564-565). Martin diagnosed

Mitchell as having a non-specified mental disease or defect. (Id. at 816-817). He explicitly

expressed no opinion as to whether Mitchell’s mental illness was drug induced. (Id. at

817). Finally, De Marchis testified that he believed Mitchell was malingering and did not

have any true psychotic disorder at all. Although he disbelieved Mitchell’s claims about

hallucinations and delusional paranoia, he testified that if those claims were true then the

most likely explanation was “either drug intake or alternatively drug withdrawal.” (Id. at

897). Therefore, De Marchis agreed that “drug induced psychosis” was “possible” in

Mitchell’s case. (Id. at 935).

{¶ 24} In our view, the trial court did not abuse its discretion in refusing to instruct

the jury about drug use potentially causing a disease or defect of the mind where (1) the

only drug found in Mitchell’s system was a trace amount of a benzodiazepine, (2) no

expert witness opined that Mitchell had a disease or defect of the mind caused by drug

use, and (3) one expert testified that “drug induced psychosis” was “possible” but that he

did not believe Mitchell had any psychosis at all.

{¶ 25} Mitchell’s second jury-instruction argument concerns the following

instruction given by the trial court: “It is not a defense that the Defendant’s reason at the

time of the offense was so impaired that he did not have the ability to refrain from doing

his act or acts.” (Id. at 1069). This instruction paraphrased R.C. 2945.391, which states
 -15-

in part: “Proof that a person’s reason, at the time of the commission of an offense, was

so impaired that the person did not have the ability to refrain from doing the person’s act

or acts, does not constitute a defense.”

{¶ 26} Despite Mitchell’s argument to the contrary, we see no meaningful,

substantive difference between the statutory language and the instruction given by the

trial court. Mitchell argues that the statute talks about “proof” whereas the trial court’s

instruction did not. Although the trial court did omit the word “proof,” we fail to see how

that prejudiced Mitchell. In essence, the trial court’s instruction presumed that “proof”

existed (which, if anything, would benefit Mitchell) and proceeded directly to the

substance of the instruction. We also reject Mitchell’s claim that the trial court’s instruction

would preclude any defendant from ever prevailing on an insanity defense. The point of

both R.C. 2945.391 and the trial court’s substantially-similar instruction appears to be that

impaired reasoning resulting in a lack of ability to control one’s conduct (i.e., an

“irresistible impulse”) does not establish an insanity defense. This is a correct statement

of law.3 See R.C. 2901.01(A)(14) (“A person is not guilty by reason of insanity only if he

proves * * * that at the time of the commission of the offense, the person did not know, as

a result of a severe mental disease or defect, the wrongfulness of the person’s acts.”).

We see no error or prejudice to Mitchell in the trial court’s paraphrasing of R.C. 2945.391.

The second assignment of error is overruled.

3 “Years ago, legal insanity in Ohio could be based upon two distinct theories. One theory
was the inability of a person to comprehend the wrongfulness of his or her actions. That
theory has been maintained in Ohio law.” State v. Muhammad, 10th Dist. Franklin No.
07AP-609, 2008-Ohio-2839, ¶ 15. “The other theory was commonly referred to as the
irresistible impulse test—the individual knew the activity was wrong but could not refrain
from doing the wrong activity anyway. The Ohio legislature redefined legal insanity in
Ohio to exclude situations involving irresistible impulse.” Id.
 -16-

{¶ 27} In his third assignment of error, Mitchell asserts that he received ineffective

assistance of trial counsel. Specifically, he argues that his attorney provided prejudicially

deficient representation by failing to object to De Marchis’ characterization of him as a

habitual criminal.

{¶ 28} The testimony in question occurred after De Marchis diagnosed Mitchell as

having “antisocial personality disorder,” which he identified as a “character disorder”

rather than a “psychotic disorder.” (Trial Tr. at 872-873). De Marchis then provided the

following explanation of an “antisocial personality disorder”:

* * * Antisocial personality disorder does not mean that you don’t like

to socialize. It’s a character disturbance that pretty much would fit what we

would describe as a habitual criminal; someone who lies, somebody who

exploits others, someone who may abuse substances, someone who

doesn’t have a good work history, someone who is not responsible—those

kinds of things.

(Id. at 874).

{¶ 29} Mitchell contends his attorney provided ineffective assistance by failing to

object to this testimony. To prevail on an ineffective-assistance claim, a defendant must

show deficient performance and resulting prejudice. Strickland v. Washington, 466 U.S.

668, 687, 104 S.Ct. 2052, 80 L.Ed.2d 674 (1984). To show deficiency, a defendant must

show that trial counsel’s representation fell below an objective standard of

reasonableness. Id. Prejudice exists and a reversal is warranted only where a defendant

shows a reasonable probability that but for counsel’s deficient performance the result of

the proceeding would have been different. State v. Bradley, 42 Ohio St.3d 136, 142, 538
 -17-

N.E.2d 373 (1989).

{¶ 30} We see no ineffective assistance of counsel here. Mitchell’s NGRI defense

placed at issue whether he had a mental disease or defect. De Marchis concluded that

he did not. Instead, De Marchis opined that Mitchell had a “character disorder,” which the

psychologist specifically identified as “antisocial personality disorder.” In our view, De

Marchis was entitled to describe antisocial personality disorder, as the meaning of that

diagnosis would not be readily apparent to the average juror. The fact that his example

characteristics of the disorder could be unflattering to Mitchell did not render De Marchis’

testimony improper. If Mitchell disputed those characteristics or believed they were

unsupported in his case, defense counsel remained free to cross examine De Marchis

about his diagnosis.

{¶ 31} Even assuming, arguendo, that the challenged testimony was improper, we

would find no prejudice. Mitchell was charged with, among other things, the execution-

style murder of his girlfriend. Defense counsel did not dispute that Mitchell committed that

offense or the others with which he was charged. The only real issue was whether Mitchell

had a mental disease or defect that caused him not to know right from wrong. That issue

was the subject of extensive testimony by three expert witnesses. We are convinced that

the challenged brief description of an antisocial personality disorder had no effect on the

jury’s resolution of the central issue in the case. The third assignment of error is overruled.

{¶ 32} The judgment of the Montgomery County Common Pleas Court is affirmed.
