We’ll never know for sure why Adam went on the shooting rampage that left 26 dead at Sandy Hook Elementary, but in a new interview, a friend of Adam’s mother insists his past experiences of being bullied played a big role. Keep reading for more details.

Marvin LaFontaine, a friend of Nancy Lanza’s, believes that the shooting spree at Sandy Hook Elementary School may have been Adam Lanza’s “act of revenge.”

Adam Lanza Bullied: Sandy Hook Shooting Was His ‘Act Of Revenge’

Marvin explains that Adam grew up as a target of relentless bullying, and that he was picked on mercilessly by his schoolmates, in an interview with the Daily News. “Nancy told me he was being picked on at school. That they were just torturing him,” Marvin says. “Adam was an easy target. He was quiet and he would never fight back.”

Furthermore, the bullying often became so bad that Nancy accompanied Adam to school like a bodyguard, though this really only made things worse for him, as Marvin explains: “Adam didn’t like her showing up.” Before driving to Sandy Hook Elementary on Dec. 14, Adam murdered his mother in their Newtown, Conn. home.

Adam may have been driven to his horrific massacre by his troubled youth, Marvin concludes: “I think Adam felt betrayed by the school and this was his act of revenge,” he states.

Adam Lanza’s Motive: Did He Resent Sandy Hook Elementary?

The troubled 20-year-old could have been harboring that resentment for his whole life. Marvin explains that as Adam grew older, the antisocial behavior that he developed as a bullied child only worsened, to the point that he would lock himself in his room for hours on end.

It’s difficult to find sympathy for a person who horrifically killed so many young people, but the picture that Marvin paints is of a truly disturbed person. A person who was mentally sick and not being treated in the necessary ways. Instead of being taken to a firing range — which is what Nancy would do — Adam more likely should have been spending his time with therapists, being treated and learning how to iron out his issues and suppressed aggression.
