UJI 14-2813. Conspiracy; proof of express agreement not necessary.

It is not necessary in proving a conspiracy to show a meeting of the alleged conspirators or the making of an express or formal agreement. The formation and existence of a conspiracy may be inferred from all circumstances tending to show the common intent and may be proved in the same way as any other fact may be proved, either by direct testimony of the fact or by circumstantial evidence, or by both direct and circumstantial evidence.
