Okla. Stat. tit. 22, § 22-914: Form of verdict

A general verdict upon a plea of not guilty, is either "guilty",

or "not guilty", which imports a conviction or acquittal of the

offense charged. Upon a plea of a former conviction or acquittal of

the same offense, it is either "for the state", or "for the

defendant". When the defendant is acquitted on the ground that he

was insane at the time of the commission of the act charged, the

verdict must be "not guilty by reason of insanity". When the

defendant is acquitted on the ground of variance between the charge

and the proof, the verdict must be "not guilty by reason of variance

between charge and proof".
