The weapon found (in the car, I think) was a .223-caliber Bushmaster rifle -- which has absolutely no purpose other than combat.

Why was it one of the weapons registered to the shooter's mother? And the two handguns were a Glock and a SIG Sauer both 9mm, both semi-automatics that fire up to 5 bullets per second.

Expensive, too. All of 'em. And registered to his mother.
