AP Source: 'Lots of Ammo' Hints at Deadlier Plan Details are emerging that the man who slaughtered elementary school children and teachers may have had even bigger, more gruesome plans. A law enforcement official says Adam Lanza had "lots of ammo" on him when he killed himself, enough to carry out considerably more carnage. The official was not authorized to release details of the case and spoke on condition of anonymity. That followed Gov. Dannel Malloy's statement Sunday that the shooter decided to kill himself when he heard first responders closing in after about 10 minutes of shootings. The shooting is the largest massacre of school-age children in U.S. history.
