The state raises two questions for review: first, whether insanity is a defense to negligent vehicular homicide, and second, if insanity is a defense, whether Curry has established the defense by a preponderance of the evidence. We answer the first question in the affirmative and the second question in the negative. Accordingly, the judgment of the court of appeals is reversed, and the decision of the trial court is reinstated.
I
Appellee was charged with a violation of R.C. 2903.07(A), which provides in pertinent part: “No person, while operating * * * a motor vehicle, * * * shall negligently cause the death of another.”
“Negligence” for purposes of the criminal code is defined in R.C. 2901.22(D):
“A person acts negligently when, because of a substantial lapse from due care, he fails to perceive or avoid a risk
In its first proposition of law, the state argues that “[i]nsanity is not a defense to the crime of negligent vehicular homicide.” In the state’s view, insanity is only a defense to a criminal charge where it negates the intent element of the offense. Accordingly, the state argues, since negligent vehicular homicide is not a crime requiring an intent to kill, insanity is not available as a defense. We believe this argument misperceives the fundamental bases of the insanity defense.
In State v. Staten (1969), 18 Ohio St. 2d 13, 47 0.0. 2d 82,
In arguing that the insanity defense is limited to offenses of which intent is an element, the state appears to confuse the insanity defense with the defense of “diminished capacity,” under which an accused is permitted to introduce evidence of a mental disease or defect to prove that he did not have the particular state of mind that is an element of the offense charged. This court, however, expressly rejected the diminished capacity defense in State v. Wilcox (1982),
This conclusion also follows from the fact that under Ohio law, a plea of not guilty by reason of insanity is an affirmative defense. State v. Humphries (1977),
Thus, the insanity defense is and always has been broader in scope than the posture argued by the state. While it is true that a legally insane defendant may lack the capacity to form the specific intent to commit a particular crime, criminal intent or lack thereof is not the focus of the insanity question. Rather, the insanity defense goes to the very root of our criminal justice system and is founded on the broader principle that an insane person may not be held criminally responsible for his conduct. See Kuhn v. Zabotsky (1967),
II
In its second proposition the state argues that the evidence is insufficient to establish Curry’s insanity defense. The test of insanity is set forth in Staten, supra, at paragraph two of the syllabus:
“In order to establish the defense of insanity where raised by plea in a criminal proceeding, the accused must establish by a preponderance of the evidence that disease or other defect of his mind had so impaired his reason that, at the time of the criminal act with which he is charged, either he did not know that such act was wrong or he did not have the ability to refrain from doing that act.”
Much of the testimony focused on the sequence of events occurring between Friday, May 30, 1986 and the morning of Tuesday, June 3, 1986, the morning of the accident. All the witnesses testified that the defendant was emotionally distraught during this period. They also agreed that the defendant had gotten little, if any, sleep during this period.
As to the defendant’s mental condition during the days before the accident, the defendant’s sister testified that the defendant at times was in “a real deep stare.” The defendant’s mother testified that when she visited the defendant on the day before the accident the defendant “* * * was staring at the Bible, just staring she wasn’t reading, she was just staring.” A deacon who had met with the defendant that evening testified that she was “just too much in a daze.” Finally, the babysitter with whom the defendant had stayed the night before the accident stated that they had prayed and discussed the Scriptures but that “in the state she [the defendant] was at, you know, I don’t think she was comprehending what I was telling her.”
The state argues that Curry’s mental condition as described above is attributable primarily to the fact that she had gotten little sleep during this period. Three of the witnesses quoted above testified that Curry appeared to be very tired and in need of sleep. The defendant’s sister admitted that she did not know the symptoms of a person who is deprived of sleep.
The defendant testified that she was extremely upset during this period as a result of the separation from her husband and the fact that, while a reconciliation was attempted, her husband was forcing her to choose between him and her religion. She further testified that she had gone without sleep from Friday, May 30 until
“In my mind, at that time, I thought I was going to heaven. And, that’s all I could think about, I thought well, if I'go this way — this way is home and that way would be heaven and so I followed the sun and to me at that time it was the Son of God and if I followed, I’d go. So, I kept going.”
The defense also offered the deposition of Dr. Thomas G. Sherman, a forensic psychiatrist who had examined the defendant on two occasions beginning approximately three months after the accident.
Having fully set forth the evidence relevant to Curry’s insanity defense, we must consider whether that defense was proven by a preponderance of the evidence. Although the statement of the trial court is somewhat unclear, the judge did state that “I do give considerable weight to the testimony of Doctor Sherman.” Since Dr. Sherman’s testimony was relevant solely to Curry’s insanity defense, it can scarcely be doubted that the trial court considered the defense and found that it had not been established.
The trial judge also stated that “I find that the defendant’s mental state at that time was such that she was not able to mentally concern herself with traffic laws * * *.” The court of appeals held that this statement “establishes that * * * [Curry] was legally insane at the time of the accident since it establishes that she did not know her act of driving left of center was( wrong.” We disagree.
This court held in State v. Thomas (1982),
Contrary to the conclusion reached by the court of appeals below, the finding by the trial court that Curry “was not able to mentally concern herself with traffic laws” is not equivalent to a finding that Curry was insane at the time of the accident. The trial court stated that Curry’s condition was “caused by a combination of her personal problems and self imposed lack of sleep[,]” and that “it was negligent for the defendant to be operating a motor vehicle at all in the mental state that she was in. Just as though she had been intoxicated.” As suggested by the trial court, a voluntarily intoxicated person may be unable to “concern himself with traffic laws,” yet such intoxication would not be a defense to negligent vehicular homicide, specific intent not being an element of that offense. See, generally, State v. Fox (1981),
This is not a case of overwhelming evidence of the defendant’s insanity. Cf. State v. Brown (1983),
For the foregoing reasons, the judgment of the court of appeals, finding appellee not guilty by reason of insanity, is reversed, and the judgment of the trial court is reinstated.
Judgment accordingly.

Dr. Sherman’s deposition was admitted, by stipulation and court approval, in lieu of a court-ordered evaluation pursuant to R.C. 2945.39. The parties stipulated that Curry was competent to stand trial, and, as to the substance of Dr. Sherman’s testimony, the state stipulated “to that testimony to the extent that were he here he would testify to that * *
