What are the elements of a premeditated murder case?

In People v. Anderson (1968) 70 Cal.2d 15, 73 Cal.Rptr. 550, 447 P.2d 942, we set out three categories of evidence which might sustain a finding of premeditated murder: (1) facts about a defendant's behavior before the killing that show prior planning; (2) facts about defendant's conduct with the victim from which the jury could infer a motive, and (3) facts about the manner of the killing from which the jury could infer that the defendant intentionally killed the victim according to a preconceived plan.
