As of Tuesday, we may learn more about Sandy Hook Elementary School shooter Adam Lanza. The FBI released more than 1,500 pages of documents on the investigation, including interviews with people who knew Lanza. Back in December 2012, Lanza killed his mother before fatally shooting 20 children and six staff members. One interviewee told the FBI Lanza never came to terms with his Asperger's syndrome and had become a "shut in." A Newton, Connecticut resident told investigators he once hacked into a government computer system, which sent federal authorities knocking at his door. Many other residents claimed they received calls from someone identifying himself as Lanza
after the shooting. But Lanza shot himself dead before the police arrived at the scene that day.
