Thirty-five years after a string of murders in which he taunted investigators, the “Son of Sam” serial killer says he is “in anguish” over the killings and wishes he could take it back.

David Berkowitz, serving a 365-year sentence in prison for killing six women, says he has undergone a religious transformation, becoming a born-again Christian.

In an interview on the cable news channel MSNBC’s website, he said: “I’d like to be remembered as a person who’s sorry for what happened and is doing everything in his power to try this … to make amends to society in any way possible.”

He murdered the women with no apparent motive, sending letters to police and newspapers stating: “I am the Son of Sam. I love to hunt, prowling the streets looking for fair game.”

Shortly after his arrest in August 1977, Berkowitz confessed to the shootings in New York between 1976 and 1977.

He claimed that he was commanded to kill by a demon who possessed his neighbor’s dog.

Berkowitz later claimed he was the shooter in only two incidents, personally killing three people and wounding a fourth. The other victims were killed, Berkowitz claimed, by members of a violent satanic cult of which he was a member.

He remains the only person charged with or convicted of the shootings.
