ORDERED that the judgment is affirmed.
The defendant and his two cousins severely assaulted the victim. The victim died from a gunshot wound inflicted by one of the defendant's cousins.
Viewing the evidence in the light most favorable to the prosecution (see People v. Contes, 60 N.Y.2d 620), we find that it was legally sufficient to establish beyond a reasonable doubt that, although the defendant did not shoot the victim, he "possessed the requisite mental culpability to sustain the conviction against him for manslaughter in the first degree" (People v. Bailey, 156 A.D.2d 454, 455; see People v. Modesto, 262 A.D.2d 586; People v. Ravnell, 199 A.D.2d 546; People v. Herring, 149 A.D.2d 731, 734). The criminal history of and alcohol abuse by the People's main witness merely raised credibility issues for the trier of fact (see People v. Santiago, 228 A.D.2d 706; People v. Hatchett, 225 A.D.2d 634; People v. Ragin, 224 A.D.2d 642; People v. Taylor, 162 A.D.2d 741, 742; People v. Hughes, 138 A.D.2d 523, 524-525). Moreover, resolution of issues of credibility, as well as the weight to be accorded to the evidence presented, are primarily questions to be determined by the trier of fact, which saw and heard the witnesses (see People v. Gaimari, 176 N.Y. 84). Its determination should be accorded great weight on appeal and should not be disturbed unless clearly unsupported by the record (see People v. Garafolo, 44 A.D.2d 86). Upon the exercise of our factual review power, we are satisfied that the verdict of guilt was not against the weight of the evidence (see CPL 470.15).
The trial court's charge, essentially quoting Penal Law § 20.00, properly instructed the jury on the standard for accessorial liability (see People v. Slacks, 90 N.Y.2d 850, 851; People v. Compitiello, 118 A.D.2d 720). Since the court sufficiently explained the applicable legal principles to the jury, it was not bound to charge the jury as defense counsel proposed (see generally People v. Gonzalez, 279 A.D.2d 637; People v. Maldonado, 127 A.D.2d 855).
