(Syllabus.)
1. Trial — Procedure on Question of Insanity of Defendant. The question of insanity of defendant may be raised in two ways: first, insanity at the time of the trial; second, insanity at the time of the commission of the offense.
2. Same — Issue of Present Insanity to Be Submitted to Separate Jury. When the question of insanity arises, it is the duty of the trial court to immediately suspend all proceedings and submit the issue of present insanity to a separate jury impaneled for that purpose only.
3. Same — Defense of Insanity at Time Offense Was Committed Is to Be Presented to Jury Trying Criminal Case. If the defense of insanity at the time of the commission of the offense is offered, this question is presented to the jury trying the defendant for the offense charged.
4. Same — Verdict of Acquittal Must State Whether Acquittal Was on Ground of Insanity. Under 22 O. S. 1941 § 1161, where the defense of insanity at the time of the commission of the crime is interposed, either singly or in conjunction with some other defense, the jury must state in the verdict, if it is one of acquittal, whether or not the defendant is acquitted on the ground of insanity.
5. Same — Procedure Where Verdict of Acquittal States Discharge of Defendant Dangerous to Public Safety. Where defendant is acquitted on the ground that he was insane at the time of the commission of the crime charged, if the jury shall state in the verdict that they deem the discharge of said person dangerous to the public peace or safety, he shall be by the trial court committed to one of the state hospitals for insane, and there to be held and kept as a patient until legally discharged.
6. Evidence — Officers Erroneously Permitted to Give Opinion That Discharge of Defendant Would Be Dangerous to Public Safety. Under the facts in this case it was error for the court to permit officers on rebuttal to give their opinion that the discharge of defendant would be dangerous to the public peace or safety of the citizens of this state.
7. Same — Proper Proof on Question Whether Defendant's Discharge Would Be Dangerous to Public Safety. The question as to whether discharge of accused would be dangerous to the public safety under 22 O. S. 1941 § 1161 should be based upon competent evidence concerning the particular crime charged, including the testimony of medical experts as to his sanity. But opinion evidence of lay witnesses that defendant's discharge is dangerous to the public peace or safety is inadmissible as invading the province of the jury.
8. Same — Scope of Proper Testimony by Nonexperts as to Insanity of Defendant. Where insanity is interposed as a defense, a nonexpert witness, after testifying to the acts, conduct and appearance of a defendant, may state whether such acts, conduct and appearance impressed him as being rational or irrational; that is, whether he was sane or insane.
9. Evidence — Inadmissibility of Opinions of Witnesses. It is a well-known general rule that witnesses are not to give their individual opinions, or state their conclusions, when the jury is equally competent as to such matter to form the opinion or deduce the' conclusion sought from the facts.
10. Evidence — Proof of Other Unrelated Crimes Inadmissible to Show Release of Defendant Because of Insanity Would Endanger Public Safety. Proof of the commission of other crimes unrelated and unconnected with the crime for which the defendant is on trial, is inadmissible when offered to show that the release of defendant because of insanity would be dangerous to the public peace or safety.
