Indirectly, yes. The kid had plenty of money. He mentions driving to Arizona to pick up lottery tickets and purchasing the Sig in another state. Beyond that I don't know much.

I can’t fathom to the end of days if everyone in his community from his parents(Hollywood though they be) to the police, his teachers and the few, if any friends he had, couldn’t see this guy had a head full snakes and a heart full of hate.

Yeah, right and someday pigs will fly.
