Trevor L. Todd, a former classmate of Adam Lanza, told The National Enquirer that Lanza had a devil worshiping page on the web, which was "weird" and "gave him the chills."
Also, Adam Lanza's childhood barber Bob Skuba told CNN that Nancy Lanza stopped bringing her son in for haircuts a few years ago.
Skuba said that Adam Lanza would never speak or even look at him: "It’s just weird that I actually touched him. I'd tried to joke with him. He wouldn’t even look at me. He would just be looking down at the tiles the whole time."
"I wish I would have killed him then. Or he should have killed himself a long time ago. He would have saved us all the trouble. I should have slit and stabbed him by accident. It would have been a lot better for those people."
Stylist Diane Harty said that Nancy Lanza hardly spoke, only to tell Adam what to do as he would not listen to anyone else.
It was also reported that Dr. H. Wayne Carver, chief medical examiner in the massacre, is seeking the help of a geneticist to see if there is any identifiable disease associated with the behavior of Adam Lanza.
Dr. Carver said: "I’m exploring with the department of genetics what might be possible, if anything is possible. Is there any identifiable disease associated with this behavior?"
One theory is that Adam Lanza was angry that his mother was planning to commit him to a psychiatric facility because he was becoming too difficult for her to handle.
Nancy Lanza may have volunteered at the Sandy Hook Elementary School, and Adam Lanza may have felt that his mother loved those children more than she loved him.
Rich Collins, a Lanza family friend, told the New York Post: "It was really hard for her as a single mother. It’s hard enough raising an autistic child, just me and my wife. I couldn’t imagine doing it alone."
