Okla. Stat. tit. 22, § 22-358: Venue - Consolidation of indictment

A. Any indictment or accusation for removal by a multicounty

grand jury shall be returned to the presiding judge without

designation of venue. Thereupon, the judge, by order, shall

designate the county of venue for the purpose of trial. The judge,

by order, may direct the consolidation of an indictment returned by

a county grand jury with an indictment returned by a multicounty

grand jury and fix venue for trial.

B. If a multicounty grand jury, pursuant to its investigation,

learns of an offense for which it lacks jurisdiction to indict, the

multicounty grand jury shall direct the Attorney General to inform

the appropriate prosecutorial authority.
