" But as will be shown, the conviction of Cantu of the crime of conspiracy has ample support in the record. [6] This court said in People v. Cornell, 188 Cal.App.2d 668 [ 10 Cal.Rptr. 717], at page 673: "A criminal conspiracy is an agreement, express or implied, to commit any crime or to do any of the acts specified by the statute. (Pen. Code, § 182.) [7] A conspiracy may be proved by direct or indirect evidence, or by both.
One who associates with a preexisting conspiracy with knowledge of the conspiracy and who performs overt acts in furtherance of the conspiracy’s unlawful purpose is liable as a conspirator. (In re Nathaniel C., supra, 228 Cal.App.3d at p. 1000; accord, People v. Cornell (1961) 188 Cal.App.2d 668, 675.) Accordingly, it is of no importance that Mejia might have become involved in the conspiracy only shortly before it ended if there was sufficient evidence that he agreed to the conspiracy’s unlawful purpose.
