Contrary to defendant's argument on appeal, the authenticity of the contraband was adequately established by evidence which provided reasonable assurances of its identity and unchanged condition (People v Julian, 41 N.Y.2d 340, 343). While there was no testimony by Property Clerk personnel or the first chemist, the contraband was under police control and remained in identifiable containers at all times. Since there is no reasonable probability that the results of the trial would have been different had the trial assistant secured and then turned over the notes of the first chemist, if any, defendant's argument that the prosecutor violated his obligations under CPL 240.20 does not warrant a reversal (People v Chin, 67 N.Y.2d 22, 33). Defendant made an issue of the notes only because the first chemist was not currently employed by the police department (see generally, People v Allgood, 70 N.Y.2d 812), but the reliability of the first chemist's conclusions was not posed as an issue at trial. We also reject defendant's argument that the testimony of the principal police witness was contrary to reason and incredible as a matter of law (see generally, People v Berrios, 28 N.Y.2d 361), and, accordingly, will not disturb the determination of the jury (People v Malizia, 62 N.Y.2d 755, 757, cert denied 469 U.S. 932). Finally, defendant's arguments that he was deprived of a fair trial by the prosecutor's summation are largely unpreserved, and in any event, without merit. The prosecutor was entitled to draw fair inferences from the evidence and to reply to counsel's summation (People v Marks, 6 N.Y.2d 67, 77-78).
