People v. Gabriel

Identification by single witness is sufficient to support conviction, if Defendant is viewed in way to permit positive ID. Mere presence at crime scene, with knowledge of crime, does not establish accountability, but active participation is not required for accountability of one Defendant for another's acts. Sufficient to infer knowledge of criminal purpose and shared criminal design, where Defendant was present with co-Defendant prior to shooting, went with him to scene, pointed a gun in victims' direction while co-Defendant fired his gun, and fled scene with him. Severance of trial from that of co-Defendant not required; no hostility between the two defenses, as Defendant's alibi defense did not implicate co-Defendant.
