New Details Released on Newtown Shooter

Neil Heslin, the father of a six-year-old boy who was slain in the Sandy Hook, on Capitol Hill, Washington, Feb. 27, 2013.

Court documents say the gunman who killed 27 people — including 20 young children — in an attack at a Connecticut elementary school, owned several guns in addition to the ones used in the attack.

Search warrants previously sealed from the public showed Thursday the gunman also owned hundreds of rounds of ammunition. Authorities found a holiday card in the gunman's home with a check made out to him from his mother for the purchase of a firearm. They also found papers from the National Rifle Association in the home.

The twenty-year-old gunman killed his mother inside their Newtown home on December 14 before driving to Sandy Hook Elementary School and killing 20 young kids and six adults. He committed suicide as police arrived on the scene.

The shooting has sparked a national debate on how to curb gun violence. President Barack Obama will deliver remarks on how to protect children from gun violence later Thursday.
