Is evidence of uncharged misconduct admissible at criminal trial?

Evidence of uncharged misconduct is inadmissible at a criminal trial if its purpose is to show the defendant had a disposition or propensity to commit the charged offense. ( 1101, subd. (a).) However, "this rule does not prohibit admission of evidence of uncharged misconduct when such evidence is relevant to establish some fact other than the person's character or disposition," such as motive, opportunity, intent, preparation, plan, knowledge, identity, or absence of mistake or accident. (People v. Ewoldt (1994) 7 Cal.4th 380, 393; 1101 (b).)
