10 of the deadliest spree killers in history of the world (With Pictures)

8. Adam Lanza

On December 14, 2012, 20-year-old Adam Lanza walked into Sandy Hook Elementary School in Newtown, Connecticut and shot 20 children and 6 staff members before turning the gun on himself. He also murdered his own mother to start his rampage. Motive for the massacre has never been confirmed and an autopsy of Lanza’s body revealed no drugs or alcohol in his system, and no evidence of a tumor or any other abnormalities in his brain. There was evidence Lanza had done a lot of research on mass shootings prior to his own rampage, but there was no conclusive evidence pointing to why he chose to kill a bunch of innocent children and their teachers.
