Sandy Hook Report Offers Grim Details of Adam Lanza's Bedroom

Nov. 25, 2013— -- intro: The gunman who opened fire on Sandy Hook elementary school last December, killing 20 students and six staff members, had collected mass murder memorabilia, including newspaper clippings, in his bedroom before the shooting.

Stockpiled in the bedroom that he almost never left were news reports about school shootings, video games that allowed the user to role play a mass shooting, and grisly photos of a dead human, covered in blood and wrapped in plastic. There were also funny videos, pictures of hamsters, and videos of him playing Dance Dance Revolution.

Lanza, 20, killed his mother at the home they shared on the morning of Dec. 14 before continuing onto the Sandy Hook school. There, he killed 26 people, mostly first graders, before taking his own life.

The report released today offers the first look at Lanza's secretive bedroom, in which he allowed no one - not even his mother - to enter, as well as his basement game room.
