NEWTOWN, CN - Family insiders said Connecticut school shooting gunman Adam Lanza was deeply disturbed and may have suffered from a personality disorder.
Adam Lanza, 20, lived with his mother. On Friday morning, it appears, Lanza shot his mother Nancy in the face and killed her. Investigators then believe he took her guns, drove her car to Sandy Hook Elementary School where he shot and killed 20 children and six adults before turning the gun on himself.
While details of the shooting are slowly being released to the public, questions still surround Lanza. A former classmate described him as a "genius" and kept to himself.
"He was really quiet, he kept to himself," Alex Israel said. "I mean, he was a little fidgety, a little uneasy sometimes if you were just to look at him."
The Sandy Hook Elementary School massacre has entangled his entire family. His mother is dead and at one point, cops believed his 24-year-old brother Ryan was the killer. There was confusion about his name because Adam reportedly had his brother Ryan's ID.
Ryan lives in Hoboken, New Jersey. He was taken in for questioning but has cooperated with police and is not believed to be involved in the killings. Ryan told authorities he had not been in touch with his brother since 2010.
Family insiders describe Adam as "deeply disturbed," possibly suffering from a personality disorder.
Adam Lanza's parents divorced in 2009. His father lives in Stamford, Connecticut and is a vice president at GE Capital.
Those who know the family are reeling and still trying to make sense of the tragedies.
"He was a nice kid, very polite," Newtown bus driver Marsha Moskowitz said. "She raised very nice boys, to me. That's why I think it's a shock to even know them and realize who they are and what he did. You can't understand what happened. That he snapped, what have you, that he took such innocent lives."
Initial reports surfaced that Nancy Lanza may have been a teacher at the school but her name does not appear on a staff list. Authorities have yet to confirm any connection so far between her and the school.
