Yet more disturbing details about the life of Sandy Hook Elementary School shooter Adam Lanza emerged on Monday when it was revealed that he drew sinister pictures of dead bodies that horrified his mother.

“One (drawing) had a woman clutching a religious item, like rosary beads, and holding a child, and she was getting all shot up in the back with blood flying everywhere,” said a friend, according to a New York Daily News report.

“Nancy was disturbed, really disturbed, but didn’t confront him,” he explained. “She wanted to think it over.”

As Breaking Celebrity News previously reported, Lanza, 20, shot dead his mother, Nancy, in her bed on Dec. 14, 2012, in Newtown, Conn., before taking an arsenal of her firearms to the school. As police drew in on him, he shot himself in the head, but not before killing a total of 26.

The latest shocking insight into the mind of the killer came from e-mails obtained by the Daily News where Nancy revealed her fears that he would suffer from the family's black plague – a genetic disorder that killed her grandfather, nearly took her life and had manifested in Adam, who had also been diagnosed with the form of autism known as Asperger’s syndrome, and a sensory perception disorder that prevented him from recognizing pain and caused him to recoil from being physically touched.
