claims that he is not guilty because he is insane. The testimony or proof of an accused's insanity must, however, relate to the time immediately preceding or coetaneous with the commission of the offense with which he is charged.[30] It is, therefore, incumbent upon accused's counsel to prove that his client was not in his right mind or was under the influence of a sudden attack of insanity immediately before or at the time he executed the act attributed to him.[31] Since insanity is a condition of the mind, it is not susceptible of the usual means of proof.

If the mental examination on accused-appellant had been promptly and properly made, it may have served a dual purpose[89] by determining both his competency to stand trial and his sanity at the time of the offense.

At this late hour, a medical finding alone may make it impossible for us to evaluate appellant's mental condition at the time of the crime's commission for him to avail of the exempting circumstance of insanity.[91] Nonetheless, under the present circumstances, accused-appellant's competence to stand trial must be properly ascertained to enable him to participate in his trial meaningfully.
