Lanza told Solomon in the New Yorker piece that he does not mourn the loss of his son.

“He said…that he really felt that he wished Adam had never been born, and he said he struggled with coming to that, but what happened was so horrific he could only wish it away,” Solomon said.

Lanza has had several “heartbreaking” meetings with families whose children were killed in the shooting.

“He said one of the families had said to him that they were ready to forgive Adam,” Solomon said. “He said a family that lost their son, their only son. He said, ‘If my trading places with them could ease their pain, I’d do it in a heartbeat.”’

In the article, Lanza indicates that he believes Adam’s diagnosis of Asperger’s syndrome may have masked potential schizophrenia.

“Adam had what was then called Asperger’s syndrome and what would now be autism spectrum disorder,” Solomon said. “He had a certain amount of autism, and the autism made him as his father said, ‘very weird.’ Because they had a diagnosis, it didn’t occur to them that anything else was wrong.
