Connecticut state police say multiple 30-round magazines and hundreds of bullets found at elementary school where 26 were killed.
State Police Lt. Paul Vance also said Sunday that authorities have publicly identified the gunman in the school rampage as Adam Lanza. They say his mother, Nancy, as was one of his victims.
Vance also detailed the guns found at the school. He says Lanza had two handguns, a Glock 10 mm and a Sig Sauer 9 mm, and a Bushmaster assault rifle that was used for nearly all his killings.
The Bushmaster is a type of gun commonly seen at competitions and was the type used in the 2002 sniper killings in the Washington area.
A fourth weapon, a shotgun, was found in the car Lanza drove to the school.
