ALLENWOOD — Adam Lanza lived in a gun lover's house. He was a gamer, a loner, an enigma. He relied on his mother for everything until the moment he shot her in the forehead.
That hazy, disordered portrait, which emerged after Lanza killed 26 people in December at a school in Newtown, Conn., was filled out Thursday when the contents of his interior life were divulged in unsealed search warrants that revealed a home brimming with weaponry, electronics and grim photos.
But the revelations spurred only more mystery.
Investigators found journals but didn't say what was written inside. They found rifles and a trove of ammunition but didn't (or couldn't) explain why the arsenal was apparently unsecured. They found books on Asperger syndrome and autism, as well as a book titled "Train Your Brain to Get Happy." They found a busted hard drive, but what was on it? They found samurai swords, knives, a bayonet, video-game consoles, pictures of a bloody dead body and a news clipping about another school killing.
They found clues — lots of clues — but if there is context to the clues in the form of motive, authorities either don't know or aren't saying. Three months after Lanza shattered a small town, setting off a renewed gun control debate, there still is no answer to the question of why he targeted so many children at Sandy Hook Elementary School.
"This is an active, ongoing investigation," Danbury State's Attorney Stephen Sedensky III said in a statement. "No conclusions have been reached, and no final determinations have been made."
The new details about Lanza came a day after authorities in Arizona released a trove of records about Jared Lee Loughner, the disturbed young man who tried to kill then-Rep. Gabrielle Giffords, D-Ariz., in 2011. In that case, Loughner's parents had recognized red flags but did not act on recommendations to have their son mentally evaluated.
