NEWTOWN, Conn. (AP) – When Adam Lanza walked out of his house for the last time, he left behind firearms and knives and more than 1,600 rounds of ammunition – taking only four guns. They would suffice.
He loaded the weapons into his car, drove to Sandy Hook Elementary School, blasted his way into the building and within five minutes fired off 154 shots with a Bushmaster .223-caliber rifle. Having slaughtered 20 first-graders and six educators, he killed himself with a shot from a Glock handgun. He still had more than 100 rifle bullets at hand.
Warrants released Thursday provide the most insight to date into the world of the 20-year-old gunman, a recluse who played violent video games in a house packed with weaponry that was all too real. The inventory of items found in the spacious, colonial-style home included books on autism, a vast array of weapon paraphernalia and images of what appears to be a dead person covered with plastic and blood.
The weapons used in the shooting had all apparently been purchased by Lanza’s mother, Nancy, with whom he lived, said prosecutor Stephen J. Sedensky III, in a statement accompanying the warrants.
She was found dead in her bed; Adam Lanza had shot her the morning of the massacre, Dec. 14. Authorities also found a gun safe in his bedroom and a holiday card from Nancy Lanza containing a check made out to her son for the purchase of yet another firearm.
Connecticut Gov. Dannel P. Malloy expressed incredulity over the access that the troubled young man had to a cache of weapons.
“There are parts of this story that are unfathomable,” he said. “How anyone would have maintained that household that way is difficult to understand.”
Mark Barden, whose 7-year-old son, Daniel, was killed at Sandy Hook, said he was not surprised by anything revealed Thursday.
“Most of this is pretty high-level stuff that we were aware of already and it just reminds me of what happened, that a gunman stormed his way into an elementary school and shot to death 26 people, 20 of which were first-grade boys and girls,” Barden said.
Investigators found a 7-foot pole with a blade on one side and a spear on another, a metal bayonet, three samurai swords, a .323-caliber bolt-action rifle, a .22-caliber Savage Mark II rifle and a .22-caliber Volcanic starter pistol. There was a military-style uniform in Lanza’s bedroom; literature seized from the house included a news article on a 2008 shooting at Northern Illinois University and a National Rifle Association guide to pistol shooting.
News outlets including The Associated Press reported previously that Lanza showed interest in other mass killings. Some, including The Hartford Courant, reported that he had a particular interest in Norwegian mass murderer Anders Behring Breivik, who killed 77 people in twin attacks in 2011 in Norway’s worst peacetime massacre.
In a duffel bag, investigators found ear and eye protection, binoculars, numerous paper targets and an NRA certificate that belonged to Adam Lanza. The NRA said Lanza was not a member.
An unnamed person told investigators that Lanza was an avid gamer who played “Call of Duty” and rarely left his home. The affidavit, which is partially blacked out, also has that person saying that Sandy Hook, the school Lanza attended as a child, was his “life.”
On the day of the massacre, Lanza took two loaded handguns to the school along with the Bushmaster rifle. A fourth gun, a loaded 12-gauge Saiga shotgun, was found in the passenger compartment of his Honda Civic, along with 70 shotgun rounds.
Lanza went through six 30-round magazines for the Bushmaster, although half of them were not completely empty, and police said he had three other 30-round magazines in addition to one that was in the rifle.
A judge’s order to seal the warrants expired on Wednesday, and a Danbury Superior Court judge granted a request by Sedensky to withhold some details. Sedensky asked to redact the name of a witness, saying the person’s safety might be jeopardized if the name were disclosed. He also asked that the release not include other information such as telephone numbers, serial numbers on items found and a few paragraphs of an affidavit.
Malloy, a Democrat in his first term as governor, said the fact that Lanza left smaller magazines at the house should boost support for a state ban on high-capacity ammunition magazines.
“That somebody could get 154 shots off in less than five minutes, kill 20 children and six adults, is disturbing,” Malloy said.
Connecticut House Minority Leader Lawrence Cafero Jr., a Republican, said he expects the General Assembly will be ready to vote next week, possibly Wednesday, on a package addressing gun control and other issues raised by the shooting.
