venue. Every person is liable to punishment by the laws of this state, for a public offense committed by him therein, except where it is by law cognizable exclusively in the courts of the United States. Evidence that a prosecutable act was committed within the state of Idaho is a jurisdictional requisite, and proof of such must be shown beyond a reasonable doubt.
(2) Venue is nonjurisdictional. Proof that venue is proper under this chapter is satisfied if shown by a preponderance of the evidence.
