Here's a little more backstory on the guy.
Apparently his mother is the crazy religious type who believes that God talks to her and induced the same delusions in her children from a very young age. To put it quite mildly, most of her family has a history of...instability. This guy in particular has supposedly spent periods of time living in the woods in my hometown when no one else would take him in.
On a personal basis I've seen firsthand that he has these weird little power trips in which he believes that he is somehow intellectually superior to those around him and thus everyone he knows is ultimately subjected to his every bidding through the subtle use of subliminal manipulation. He always had these far-fetched dreams of one day becoming a dictator and we were often subject to rants about how he would change the world if given the slightest little sliver of power. He even went so far as to write up a demerit system on the wall in my girlfriend's little brother's room and contrive weird punishments for people who didn't act accordingly in his presence. Needless to say, he was always the dungeon master.
He sometimes talked about wanting to kill another person, and when he did he always said that he would save part of the body so that my girlfriend could eat it. I never really thought much about it though, as he just seemed like another harmless little dude who spent way too much time toking up and indulging strange fantasies.
We're also reasonably sure that this guy snuck into my girlfriend's dad's old house and bludgeoned 11 puppies to death with some sort of blunt object. One of our old dogs had a litter of pups and her dad couldn't keep them at his new place so he left them in the old house and someone came by to feed and water them every day. Alas, one day someone showed up to check on them and found them all lying in the middle of the living room with their heads bashed in, most of them still alive and suffering greatly. They all had to be put down.
This happened around the time that he was supposedly living in the woods around the house, and we all had strong suspicions that he was sneaking into the old house at night to sleep.
So yeah, this is one fucked up dude we're talking about here. Crazy, eh?
