I’m still at the wondering out loud stage, but so far nada, zip, zilch on this guy other than the biggie.
A few things are bubbling to the top:
He had a crush on some chick that ran off with a black guy a couple of years ago. That, according to an acquaintance, was what “pushed him over the edge”. You know who else gets pushed over the edge a lot? Schizophrenics. He looks crazier than a shithouse rat. Mostly it’s the hair.
He’s on more than a couple of psychotropic meds.
Recent drug (meth and other stuff) that landed him in trouble with the law, and heavy meth usage will make even normal people nutty.
For a while, his mom took away his gun, so SHE at least knew, or suspected, something wasn’t right with junior.
I think the guy was an athiest too, as evidenced by the selection of his target.
Really, other than his dislike for blacks, this guy looks and acts like your average beta hipster emo, and not the second-coming of the Third Reich.
All the interviews with people that knew him are heavily edited and ONLY cover the race angle, and last only a few seconds.
