In the initial aftermath of the attack at Sandy Hook, it was reported that Adam Lanza had deleted his computer files. Among other details of the investigation, this document provides information regarding Lanza’s electronic files that investigators were able to recover. In addition, there is a summary of “The Big Book of Granny,” a piece of writing created by Lanza and a peer. The story includes a character who states, “I like hurting people … especially children.” Also, in one “episode,” Granny’s son shoots her in the head; in other words, a son shoots his own mother in the head. This is what Lanza ended up doing in real life.
