NEWTOWN, Conn. —
At the Lanza house, investigators found books about autism and Asperger’s syndrome, as well as one with tabbed pages titled “Train Your Brain to Get Happy.” Adam Lanza was said to have been diagnosed with Asperger’s.
But the warrants also reveal an intense interest in weaponry and violence.
A gun locker in Lanza’s bedroom was open when police arrived at the house in the aftermath of the shootings, and there was no sign it had been broken into.
Investigators found a 7-foot pole with a blade on one side and a spear on another, a metal bayonet, three samurai swords, a .323-caliber bolt-action rifle, a .22-caliber Savage Mark II rifle and a .22-caliber Volcanic starter pistol.
