The Sandy Hook gunman worshiped the devil and had an online page dedicated to Satan, a former classmate revealed, as his childhood barber recalls Adam Lanza never spoke and would stare at the floor every time he had his hair cut.

Lanza's worshiping page had the word 'Devil' written in red, Gothic-style letters against a black background, Trevor L. Todd told The National Enquirer, something which he said was 'weird' and 'gave him the chills'. 

The FBI are trying to piece together his smashed up hard drive to see if his online footprint will reveal any motive for the killing, but they strongly believe he made use of devil-worshiping and suicide sites and boasted of his murder plans on message forums.

Adam Lanza's childhood barber Bob Skuba revealed today that Nancy Lanza stopped bringing her son in for haircuts a few years ago so he thought he had moved away from the area.

Time was running out: Nancy Lanza was searching for other places to have her son Adam educated and traveled all over the world to find something suitable

He told CNN that Adam would never speak or even look at him any time he came in for a cut, which was every six weeks for years.

'It’s just weird that I actually touched him. I'd tried to joke with him,' Skuba said. '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.'

Cutting Adam Lanza’s hair 'was a very long half an hour. It was a very uncomfortable situation', stylist Diane Harty said.

She said that she never heard his voice even once and that Nancy, a divorcee, also hardly spoke - only to tell Adam what to do as he would not listen to anyone else.

It also emerged today that the chief medical examiner in the massacre is enlisting the help of a geneticist to see if they can find a biological motive behind why the 'troubled genius' shot dead 20 children and six adults at Sandy Hook Elementary School on Friday.

Dr H. Wayne Carver says he wants to know if there is any identifiable disease associated with the behavior of the shooter, especially as Asperger's syndrome - which Adam is thought to have suffered from - is not associated with violent behavior.

'I’m exploring with the department of genetics what might be possible, if anything is possible,' Dr Carver said. 'Is there any identifiable disease associated with this behavior?'

He is also awaiting toxicology results.
