Order unanimously affirmed. Memorandum: County Court properly denied the motion of defendant pursuant to CPL 440.10 to vacate the judgment convicting him of two counts of murder in the second degree. In support of the motion, defendant presented evidence that the People's expert witness at trial gave false testimony regarding his credentials. While that evidence "might have affected the jury's assessment of his credibility, there is nothing in the record indicating that the prosecution was aware, or should be charged with knowledge that he was misrepresenting his credentials" ( People v. Irvin, 180 A.D.2d 753, 754, lv denied 79 N.Y.2d 1002). Thus, vacatur is not warranted under CPL 440.10 (1) (c). Further, there is no reasonable probability that the verdict would have been different had the evidence been available to defendant and used by him to impeach the expert ( see, People v. Vasquez, 214 A.D.2d 93, 101-102, lv denied 88 N.Y.2d 943).
We have reviewed defendant's remaining contentions, including those raised in the pro se supplemental brief, and conclude that they are without merit.
