It is impossible to hang oneself.
Even with your blanket. There is a whole science behind preventing self hangings in prisons. They even have engineers who design these facilities with self hanging prevention as the first priority.
Been there. Now if they had said he bashed his head into a a wall, metal bunk, the bars, or the toilet and died from a concussion and head injuries I would believe it, but it would take some time for it to be successful. It’s about the only way you can do it other than getting access to poison.
Well yes actually you can but the bulls come in cut you down and beat the hell out of you. You can hang yourself but you can’t hang yourself to death only to the infirmary.
