Son of Sam: multiple shooters, thrill kill murder cult that met at Untermeyer Park (and still does)

"I believe that David Berkowitz did not act alone, and in fact it has crossed my mind that this .44-caliber pistol that was the weapon used in the shootings that we witness was passed around to a number of people," Queens District Attorney John Santucci said on TV at the time.

Berkowitz pleaded guilty and was eventually sentenced to six consecutive life terms of 25 years to life.

Several years later, on two different occasions, investigative reporter Maury Terry interviewed David Berkowitz in prison for a documentary series. In these rarely seen meetings, Berkowitz tells Terry that he was not the only shooter.

Terry: "Now, there were a series of eight attacks, known as the 'Son of Sam' killings."

Berkowitz: "Yeah."

Terry: "Did you do all of them?"

Berkowitz: "I was at all of them. I was at more or less at all of them, scouting the areas and reporting back on likely targets and things. And I did not pull the trigger at every single one of them, and I believe the police do know that."

Berkowitz claimed his accomplices were fellow members of the 22 Disciples of Hell Satanic cult, a group he joined when he was 22, and the killings were sacrifices to their Satanic gods.

Berkowitz agreed to go through each shooting, saying which ones he did and which ones he didn't -- including Carl Denaro's.

Terry: "Carl Denaro and Rosemary Keenan in Queens?"

Berkowitz: "No."

Terry: "That wasn't you?"

Berkowitz: "No."

Terry: "Were any of the .44 shootings done by females?"

Berkowitz: "Uh, yes."

Terry: "Would that have been one shooting or two?"

Berkowitz: "One I know of, possibly two. Well, I know that Carl's was definitely a woman."

Berkowitz refused to name any living co-conspirators for fear of reprisals against his family. But Denaro may have an idea of who she is.

"All indications point to a female who was in the cult," said Carl Denaro. "We can actually place her within two blocks of the shooting, and she is still alive. She would be 71 years old now."

Who does Denaro think shot him?

"I'd rather not say," said Denaro.

Denaro hopes one day there will be enough evidence to have the case re-opened. Until then, he counts his blessings he's alive, that he survived when tragically so many didn't.

"I always consider myself very lucky, extremely lucky," said Carl Denaro.

Even though David Berkowitz says he didn't shoot Carl Denaro, he says he deserves to be where he is, in prison. In fact he's refused parole for the last 15 years. His next parole hearing is scheduled for May 2018.
