Given the fact that he is obviously a little messed in the head, it wouldn't be too difficult to suggest to him that he draw some pictures detailing his feelings while he was in prison. This could be done by a shrink, or his lawyers. It also wouldn't be too hard to lead him towards drawing the desired images.
