NORWALK - The father of the Newtown school shooter has broken his silence.

Peter Lanza told the New Yorker Magazine that he believes his son, Adam Lanza, was evil and wishes he had never been born.

Lanza told the magazine during a series of interviews that he hadn't seen his son in more than two years. He also said he wishes he could trade places with the victims' families.

Lanza says his son struggled with emotions as a child, but there weren't any indications that he'd become a mass murderer. He and his now dead ex-wife, Nancy Lanza, tried to get help for their son. They took him to various experts for diagnoses and treatment, but nothing helped.

Adam Lanza, 20, shot his mother to death before killing 20 children and six educators at Sandy Hook Elementary School in 2012. Peter Lanza says he has no doubt that his son would have killed him, too.
