Lanza made bed, covered windows in home before massacre

A clearer picture is emerging of the moments leading up to the deadly massacre at the Sandy Hook elementary school in Newtown, Conn. "The Hartford Current" says Gunman Adam Lanza shot his mother four times with his 22-caliber rifle. Black garbage bags covered windows sealed with duct tape and Lanza's bed was neatly made.
