Have you looked? It's all over the news. Lanza forced his way into the school with an AR-15, a Glock 10mm and a Sig Sauer 9mm. He killed the children with the AR-15 and shot himself with one of the handguns. The police have not released what handgun he used. The police found a shotgun in the trunk but have not released the details of make and model. In time, the police will release all the details of this crime.
I'm not making this stuff up.
Maybe something like this:
Lanza didn't use a Beretta .22LR. You seem to have issues accepting the truth?
