In People v. Sully (1991) 53 Cal.3d 1195, the California Supreme Court held that evidence of the imprisonment and sexual assault of one surviving victim and the imprisonment and assault of another was admissible on the issue of the defendant's intent as to the charged first degree murders of still other victims. (Sully, supra, 53 Cal.3d at pp. 1224-1225.) The Sully court did not specify for what intent--whether it was the intent to kill or premeditation and deliberation or both, the evidence was admissible.
