That's crazy. I have a second cousin who steals crap from other relatives then gives it to his kids, pretending he spent money on them instead of buying dope.
Wow, so this is what schoolkids talk about when they're on Winter Break. For the OP, sounds like your second cousin has any combo of a)weird, b) paranoia, c) Obsessive Compulsive behavior.
I've got ADHD, and do not believe in anything like a living MJ or Elvis, nor am obsessed with hoaxes. Maybe he's just weird.
OCD does not equal OCP (Obsessive Compulsive Personality)/Obsessive Compulsive Behavior. Incidentally, just cause you have OCD, doesn't mean someone else with OCD has the same obsessions or compulsions.
