He had a Bushmaster which appears to have been his primary weapon. They sell a 30 round magazine on the Internet. I don’t know if that is what he used though.
The murderous psycho could have used a single action revolver, a knife, club or sword. Who was going to stop him from killing 6 year old defenseless children?
All reports I've read said the Bushmaster was in the trunk of the car and not used. Just two hand-guns. Is this a new revelation? Not saying you're wrong, just everything up to this morning said it was found in the trunk of his mom's car, which he drove to the school, after the shooting stopped.
The AR-15 was locked in the car's trunk.
He killed 20 children with handguns, a Glock and a Sig.
You will hear more and more about his rifle, but his rifle had nothing to do with this crime.
