Teacher: US gunman was loner who didn't feel pain

At Newtown High School, Adam Lanza had trouble relating to fellow students and teachers, but that was only part of his problem. He seemed not to feel physical or emotional pain in the same way as classmates.


Richard Novia was the school district's head of security until 2008 and advised the school technology club that Adam and his older brother belonged to. He said Lanza clearly had disabilities. "If that boy would've burned himself, he would not have known it or felt it physically," Novia told The Associated Press in a phone interview. "It was my job to pay close attention to that." (AP)
