Adam Lanza Fired 154 Rounds From Bushmaster In Five Minutes

The first detailed account of the Newtown shootings is beginning to emerge in a case marked by caution, reticence and horror, and prosecutors have revealed some key information about the devastating school shooting at Sandy Hook Elementary that left 20 small children and six adults dead in its wake.

A tightly sealed investigation and little detail about Adam Lanza’s history and rampage have frustrated a public looking for answers, but a clearer picture of what happened that terrible day is beginning to emerge months after the massacre.

A search of the home Lanza and mother Nancy shared revealed a “veritable” arsenal of not only guns but swords and knives, and prosecutors began to reveal some of the findings Wednesday. NBC reports:

“Authorities found at least nine knives, three Samurai swords, two guns and a 7-foot, wood-handled pole with a blade on one side and a spear on the other … Authorities also recovered a National Rifle Association certificate, seven of Lanza’s journals, drawings that he made and books from the house, including an NRA guide to the basics of pistol shooting.”

During the course of the shooting inside Sandy Hook, which lasted no more than five minutes, Lanza used a Bushmaster .223-caliber XM15-E2S rifle with a 30-round magazine to fire off 154 rounds, one of at least three firearms found on the scene in Newtown.

Investigators also revealed that a witness said of Adam Lanza the day of the shootings that he was a “shut-in and an avid gamer who plays Call of Duty, amongst other games.” That witness’ name has been redacted for the time being.

Last week, it was revealed that Lanza had compiled a detailed spreadsheet of other mass killings before the Sandy Hook Elementary School shooting.
