NEW HAVEN, Conn. - The Connecticut prosecutor leading the investigation into the Newtown school shooting says the gunman killed the 26 victims and took his own life within five minutes of shooting his way into the building.
Search warrants say the 20-year-old gunman, Adam Lanza, was found dead wearing a bulletproof vest and military-style clothing.
State's Attorney Stephen J. Sedensky III says Lanza killed all the victims inside Sandy Hook Elementary School with a Bushmaster .223-caliber rifle before taking his own life with a Glock 10 mm handgun. He says Lanza also had another loaded handgun with him inside the school as well as three, 30-round magazines for the Bushmaster.
A loaded 12-gauge shotgun was also found in the passenger compartment of the car Lanza drove to the school containing 70 shotgun rounds.
Investigators also found articles on other shootings and a holiday card containing a check made out to Adam Lanza for the purchase of a firearm, authored by his mother, Nancy Lanza. And investigators found books about living with autism and Asperger's syndrome, as well as an NRA guide to pistol shooting.
Twenty-year-old Adam Lanza shot his mother in the forehead inside their Newtown home on Dec. 14 before driving to Sandy Hook Elementary School and killing 26 people, including 20 first-graders. He killed himself as police arrived.
