Appeal by the defendant (1) from a judgment of the Supreme Court, Westchester County (Colabella, J.), rendered January 5, 1984, convicting him of robbery in the first degree (two counts) and sodomy in the first degree (two counts), upon a jury verdict, and imposing sentence, and (2) by permission, from an order of the same court, entered May 13, 1985, which denied his motion pursuant to CPL 440.10 to vacate the judgment of conviction.
Ordered that the judgment dated January 5, 1984, is reversed, as a matter of discretion in the interest of justice, and a new trial is ordered; and it is further,
Ordered that the appeal from the order entered May 13, 1985, is dismissed as academic in light of our determination on the appeal from the judgment.
The defendant was convicted on the basis of the eyewitness
Specifically, we find reversible error to have been committed in the prosecutor’s questioning of Lieutenant Carol Hope, the sex crimes investigator who interviewed the two victims on the night of the crime. The sum effect of Lieutenant Hope’s testimony was to improperly bolster the credibility of the identifying witness while explaining away, by means of unqualified opinion, the inability of the other victim to make an identification (see, People v Ciaccio, 47 NY2d 431; People v Cruickshank, 105 AD2d 325, 331, affd 67 NY2d 625). Among the testimony elicited was the hearsay statement that the identifying witness had said that "she would have no trouble recognizing [the assailant] again, if she ever saw him again” (cf., People v Fogarty, 86 AD2d 617). Equally improper, and just as damaging, was Lieutenant Hope’s testimony concerning the nonidentifying witness’s "repressing” and "blocking * * * out” of information about the event, which referred to a psychological phenomena regarding which no qualifications or expertise on the part of Lieutenant Hope had been established (see, Fisch, New York Evidence § 428 [2d ed]; cf., People v Benjamin R., 103 AD2d 663, 668-669; People v Fisher, 73 AD2d 886, affd 53 NY2d 907) and which was an obvious effort to explain away the fact that the nonidentifying victim could not identify the defendant as the perpetrator of the crime. This error was compounded on summation by the prosecutor’s repeated comments that the nonidentifying witness had "blocked out” the event (see, People v Fogarty, supra). These errors, although unpreserved, combined to deprive the defendant of a fair trial and thus require a reversal. The defendant’s remaining claims of trial error have been examined and found to be without merit.
Although we have dismissed as academic the appeal from the order denying the defendant’s CPL 440.10 motion, we note that had reversible trial error not been found we would have
