Adam Lanza has been positively identified as the shooter, with Vance, the state police spokesman, saying Lanza committed suicide by shooting himself with a handgun.
Vancy also announced that authorities have identified the woman found dead in a Newtown home as Nancy Lanza, the shooter’s mother. She suffered “multiple gunshot wounds,” and her death is considered a homicide, Vance said. Nancy and Adam Lanza lived together in the same house.
Adam Lanza used an AR-15 “assault-type weapon” made by Bushmaster at Sandy Hook school, Vance said. He fired “multiple magazines” — each with 30 bullets — from that weapon.
Lanza shot his way into the school; he wasn’t buzzed in through the security system recently implemented by Principal Dawn Hochsprung. “He penetrated the building by literally shooting an entrance into the building,” Connecticut Gov. Dannel Malloy said. “That’s what an assault weapon can do for you.”
The governor said Sunday that he broke the news to families in Newtown — some of whom had waiting around a firehouse for hours, “clinging to hope” — that their loved ones were not among the dead. “You can never be prepared for that,” Malloy told CNN.
