The release comes more than three months after Adam Lanza fatally shot 26 people at an elementary school.

NEWTOWN, Conn. -- Hundreds of rounds of ammunition, guns, knives and three samurai swords were among the items seized from the home of shooter Adam Lanza in the days after the tragedy at Sandy Hook Elementary School, search warrants released Thursday revealed.
The documents, and a statement issued by authorities, provide painful details surrounding the events of Dec. 14 in this scenic town 60 miles from New York City.
Danbury State's Attorney Stephen Sedensky'sstatement says Lanza, 20, killed 20 students, six adults and himself at the school in less than five minutes. All were killed with a Bushmaster .223-caliber rifle except for Lanza, who took his own life with a Glock 10 mm handgun.
The Bushmaster was loaded with a 30-round magazine, and 14 rounds remained in the magazine when the Bushmaster was recovered by police, Sedensky said. There was one round in the chamber. He said Lanza had another loaded handgun with him inside the school as well as three, 30-round magazines for the Bushmaster.
Sedensky said Lanza's body was found dressed in military garb and a bullet-proof vest.
There was "no indication of a struggle" when Lanza shot his mother, Nancy, with a .22-caliber rifle as she slept in the home they shared shortly before the bloodbath at the school, Sedensky said.
The guns Lanza used were apparently purchased by Nancy Lanza, he said. Despite press reports that Adam Lanza had tried to buy at least one gun before the rampage, there is no indication that he attempted a purchase and was denied, Sedensky said.
The four warrants released Thursday involve searches at the Newtown home on Yogananda Street and for the black Honda Civic that he drove to the school on Dec. 14. The warrants were sealed for 90 days in late December.
Sedensky asked Judge John Blawie to seal certain information, including the identity of a witness and undisclosed items obtained during the searches, for another 90 days.
The warrants say that a loaded 12-gauge shotgun was found in the glove compartment of Lanza's Honda Civic. Two magazines containing 70 rounds of Winchester 12-gauge shotgun rounds also were found in the car.
At the house, authorities found hundreds of rounds of ammunition and numerous knives, including samurai swords. They found a military-style uniform in Lanza's bedroom and handwritten notes containing the addresses of local gun shops. Investigators also found books about autism and Asperger's syndrome as well as an NRA guide to pistol shooting.
The documents indicate authorities found a brown gun safe with shotgun shells and numerous boxes of bullets. In a bedroom closet, they found ear plugs, a handwritten note regarding ammunition and magazines, paperwork on guns and a metal bayonet.
In a top drawer of a filing cabinet, they found paper targets. In a duffel bag, they found ear and eye protection, binoculars, numerous paper targets and Lanza's NRA certificate.
