FACES OF THE INNOCENT LIVES SNUFFED OUT BY THE SANDY HOOK KILLER

20 kids, 12 girls and 8 boys, all within ages 6 and 7, were killed in the tragic shooting at the Sandy Hook Elementary on Friday. The gunman, Adam Lanza, shot each of the kids up to 11 times in what is now being referred to as a revenge attack. The killer apparently had visited Sandy Hook Elementary the day before Friday's massacre during which he was involved in an altercation with four members of staff - three of whom are now dead. The fourth teacher wasn't at school yesterday and is currently being interviewed by investigators.
