Where accused found to be insane, jury not to find verdict on indictment

(1) If, during the trial of any accused person, he appears, after the hearing of evidence to that effect or otherwise, to the jury charged with the indictment, to be insane, the court shall in that case direct the jury to abstain from finding a verdict upon the indictment and, in lieu thereof, to return a verdict that the accused is insane. (2) A verdict under this section shall not affect the trial of any person so found to be insane for the crime for which he was indicted, if he subsequently becomes of sound mind.
