New police documents were released today from the ongoing investigation into the Sandy Hook Elementary School shooting in Newtown, Connecticut, including search records that reveal shooter Adam Lanza had amassed a gigantic home arsenal. Among the items that were seized from the Lanza home:

  • 1,400 rounds of ammunition, and numerous magazines, for various types of weapons
  • An open gun safe, with no sign of force entry. Most of the ammo was stored in the safe.
  • A .22-caliber rifle
  • Nine knifes, one bayonet, three samurai swords, and some kind of double-bladed spear
  • A rifle scope, binoculars, and several holsters
  • Various other items used by sports shooters and hunters, such as eye and ear protection, and paper targets (and an NRA certificate) [Update: The NRA says "there is no record of a member relationship" between them and either of the Lanzas, but the police report only says "certificate," which could mean a number of things that aren't membership.]
  • Video game consoles (including the first-person war game Call of Duty), multiple cellphones, and notes about local gun shops
  • Books on mental health and firearms (titles included Look Me in the Eye — My Life with Asperger's; Born on a Blue Day — Inside the Mind of an Autistic Savant; and NRA Guide to the Basics of Pistol Shooting)

The inventory is not complete, however, as some of the documents are still being withheld at this time. For example, there's no mention of a supposed spreadsheet where the shooter kept detailed notes of other famous mass killings. That doesn't mean it doesn't exist, but talk of this detail in the media has drawn the ire of some victim's families and prosecutors, who feel that police are revealing too much information other law enforcement officials, but not the public.

The police also revealed some new details about their understanding of what actually happened inside Sandy Hook that day. Police say Lanza killed all 26 victims by firing more than 100 shots from his Bushmaster .223-caliber rifle, before using a handgun to shoot himself, and that he was dead within five minutes of entering the building. He also had another fully-loaded handgun, three 30-round magazines for the rifle, and a loaded shotgun in his car outside.

Lanza's body was found wearing a bullet-proof vest. When the police went to the Lanza home, they found his mother had been shot once in the head. Another rifle was found near her body.

The families of the victims received a private briefing on the information last night, ahead of the media release this morning. Police say the investigation will continue until at least June, when Lt. Paul Vance expects to release a fuller report.
