NEWTOWN, Conn. (AP) -- 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.
Meanwhile, the nurse at Sandy Hook Elementary School says she and the school secretary stayed hidden in a supply closet for almost four hours after the Connecticut school massacre had ended, leaving 20 children and six adults dead.
Sally Cox told ABC's "Good Morning America" on Monday that she knew "something terrible was happening" Friday morning when she heard loud popping sounds and the school secretary called out to her. She says she went under her computer desk, and the gunman entered her office. She says she could see his legs from the knees down, his boots facing her desk. He then left and closed the door.
She says the secretary raced into her office and they called 911 and hid in the closet. Cox says they were "petrified" and "didn't know how many there could have been."
