Adam Lanza fired 155 bullets in less than five minutes on the day he killed 20 children and six adults at Sandy Hook Elementary School, court documents have revealed.
NBC reports the total shots fired included 154 fired from a Bushmaster .223-model rifle and a final bullet, fired from a Glock 10mm handgun, that Lanza used to take his own life.
Three Samurai swords were also recovered from the Newtown, Connecticut home that Lanza shared with his mother, authorities said as they released search warrants from the second-worst school shooting in American history.
