Adam Lanza stayed at home mostly, a witness said, playing video games such as "Call of Duty." But on December 14, 2012, he went out -- armed with 10 30-round magazines for his semiautomatic Bushmaster .223 caliber model XM15 rifle and bullets for his two handguns and a shotgun. Lanza didn't make it home alive. Nor did the 26 people -- 20 of them schoolchildren ages 6 and 7 -- he shot dead in less than five minutes, firing one bullet roughly every two seconds he was at Sandy Hook Elementary School. These were among the details spelled out Thursday in five search warrants and other material tied to the grisly shooting at the Newtown, Connecticut, school, as well as in a statement from a local top prosecutor. Together, the newly released documents help paint a clearer picture of what happened.
