i don't think so.. if this guy was motivated by rage (i.e. his mother got denied coverage and died) we'd see some form of that at the crime scene, like after the gun ran out the shooter would've gone over and started yelling or kicking him. people who are dead inside and seeking revenge don't care about planning escapes, but this shooter was in and out fast and didn't make it personal. the other thing is whomever did it had to know where he'd be, try that as an outsider pleb. the timing is too perfect, just before he gives this investor conference. it sounds more like somebody wanted him out of the way rather than revenge.
