Appeal from a judgment of the County Court of Albany County, rendered September 25, 1975, upon a verdict convicting defendant of the crime of murder in the first degree. In his confession, the voluntariness of which is not challenged on appeal, the defendant admitted shooting to death a Jewish door-to-door salesman (who had been coming to defendant's house for years) in retribution for the death of George Lincoln Rockwell. Qualified psychiatrists, who had made adequate preparation, testified for both the defense and prosecution on the question of sanity (see Penal Law, § 30.05). Where there is a serious flaw in the testimony of the People's experts, the jury's determination is set aside (see, e.g., People v Higgins, 5 N.Y.2d 607 [prosecution's two experts did not examine defendant and one testified equivocally]; People v Slaughter, 34 A.D.2d 50 [prosecution's expert examined defendant cursorily and failed to review crucial medical records]; People v Lee, 29 A.D.2d 837 [expert, retained on morning of his testimony, merely examined defendant's records for 30 minutes]; cf. People v Silver, 33 N.Y.2d 475; People v Thompson, 34 A.D.2d 1097; and People v Hari, 30 A.D.2d 1046 [no expert opinion to rebut defendant's expert proof of insanity]). Absent such flaws, the jury's finding of sanity will not be disturbed (People v Wood, 12 N.Y.2d 69; People v Rock, 49 A.D.2d 666, affd 42 N.Y.2d 845). Judgment affirmed. Greenblott, J.P., Mahoney, Main, Larkin and Mikoll, JJ., concur.
