The following excerpt is from People v. Hernandez, H035408 (Cal. App. 2011):
"We hold that a predicate offense may be established by evidence of an offense the defendant committed on a separate occasion. Further, that the prosecution may have the ability to develop evidence of predicate offenses committed by other gang members does not require exclusion of evidence of a defendant's own separate offense to show a pattern of criminal gang activity." (People v. Tran, supra, 51 Cal.4th at p. 1044.)
