Unsealed documents reveal more about Sandy Hook shooter

Sandy Hook shooter Adam Lanza

DANBURY, Conn. – The Lanza home seems to be frozen in time, a Christmas wreath still hangs on the door.

But search warrants unsealed Thursday describe a fortress behind these walls.

They outline an arsenal of weapons; guns, knives and swords, and more than 1,000 rounds of ammunition.

Most of the firepower was found in gunman Adam Lanza’s bedroom.

Authorities are searching for any clues that might lead to a motive in the killing spree.

Investigators found a newspaper clipping about a fatal shooting at Northern Illinois University.

They also found drawings, seven handwritten journals and graphic crime scene photos of what appear to be dead bodies.

Also in the home, a report card from his time as a student at Sandy Hook Elementary.

The documents reveal comments from a witness, who told FBI agents Lanza rarely left his house, was an avid video gamer and that Sandy Hook Elementary was his “life.”

The newly-released information also provides new details from the crime scene.

Police said Lanza fired 154 shots in less than five minutes when he killed 20 first graders and six staff members at Sandy Hook Elementary.

One of those victims was 7-year-old Daniel Barden.

Daniel’s father, Mark Barden, said, “I think the shock is wearing off and the reality is starting to sink in a little bit and it’s really, really, really hard; the days seem to be harder now.”

Daniel wanted to be a firefighter, a dream honored by first responders who lined the path of his funeral.

For his family, the release of new information is just the next difficult step in their struggle without him.

“There’s not going to be closure,” Barden said. “I mean we need to try and move on and progress and evolve as a society, for sure, but for me personally, I’ll never get over the loss of my Daniel.”

A sense of loss that continues to haunt this grieving community and the nation.
