Conviction for first-degree murder and other crimes is affirmed. The Court held that New York's standard for admitting evidence of third-party culpability, articulated in People v. Primo, 96 N.Y.2d 351 (2001), is consistent with Holmes v. South Carolina, 547 U.S. 319 (2006) and does not infringe on a defendant's constitutional right to present a complete defense.
