NEWTOWN, CT (CBS News) — The FBI has released more than 1,500 pages documents on the investigation into the 2012 mass shooting at Sandy Hook Elementary School in Newtown, Connecticut, that left 26 children and teachers dead.
Many of the documents released Tuesday had large sections redacted. They include reports by agents who interviewed people about shooter Adam Lanza, who killed himself as police arrived at the school.
An unidentified person told an agent that Lanza’s mother, Nancy Lanza, was concerned about him a month before the shooting because he had become a “shut in” who hadn’t gone anywhere in three months. Adam Lanza fatally shot his mother before going to the school.
Several residents told authorities they received death threats after the shooting in phone calls from someone identifying himself as Adam Lanza.
Another person interviewed said Nancy Lanza told them her son hacked “into a government computer system” and federal agents showed up to their home. They said Nancy Lanza believed the agents were from the CIA and FBI and they said if her son was smart enough to hack the computer he could have a job with them someday.
