He died in a prison riot while serving three life sentences in Angola for killing demons who attacked him while he was robbing a bank. His defense of “he was a demon, Your Honor. A crap load of them were trying to kill me and if I hadn’t killed them, they’d have killed me where I stood, then taken over the city and enslaved all you petty and pathetic humans” didn’t sit well with the judge. And they refused to allow an insanity plea since his whole defense was based on: "I am not insane. You pathetic humans have to understand that demons need killing."
