154 Rounds In Five Minutes

More details have emerged about Adam Lanza:

Adam Lanza left a home stuffed with weaponry and carried out the massacre at Sandy Hook Elementary School in a 154-bullet barrage that took less than five minutes, investigators said Thursday in the first detailed account of his surroundings and troubled state of mind. Search warrants from the second-worst school shooting in American history revealed that the home Lanza shared with his mother in Newtown, Conn., was a veritable arsenal: Authorities found at least nine knives, three Samurai swords, two rifles, 1,600 rounds of ammunition 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.

Also found was a Christmas present check from Lanza's mother for him to buy another gun.
