1019. Special verdict if jury finds that accused was mentally ill at time of offence
Where, in any indictment, any act is charged against any person as an offence, and at the trial evidence is given that he or she was mentally ill, so as not to be responsible, according to law, for his or her actions at the time when the act was committed, then, if it appears to the jury that he or she committed the act charged, but was mentally ill at the time when he or she did it, the jury shall return a special verdict to the effect that the accused was guilty of the act with which he or she is charged but was mentally ill at the time when he or she committed the act.
