There was evidence the Newtown school shooter had an interest in children that could be categorized as pedophilia, but there was no proof he acted on it, according to FBI documents released Tuesday. The records were among more than 1,500 pages of documents released by the FBI in connection with its investigation of the December 2012 shooting at Sandy Hook Elementary School, where Adam Lanza killed 20 first-graders and six educators before killing himself as police arrived.
