The following excerpt is from U.S. v. Rendon-Duarte, 482 F.3d 1080 (9th Cir. 2007):
Federal Rule of Evidence 404(b) limits the admissibility of evidence of prior acts to those which serve as proof of "motive, opportunity, intent, preparation, plan, knowledge, identity, or absence of mistake or accident." We use a four-part test to determine the admissibility of evidence under Rule 404(b). United States v. Arambula-Ruiz, 987 F.2d 599, 602 (9th Cir. 1993).
