Chilling moment 'serial killer' called into Howard Stern Show and confessed to murdering 12 prostitutes

A man who claimed to be a 'serial killer' once called up The Howard Stern Show to openly admit that he killed 12 prostitutes.

The disturbing phone call was recorded during a 1997 episode of the American radio show, and has since resurfaced on social media.

Watch below:

Going by the name 'Clay', he rang up saying he planned on leaving clues for the detectives at the various crime scenes, but it wasn't needed.

"I wanted to baffle people, but it turned out that no one noticed for a long time," he told host Howard Stern.

"I never sent the clues, I never left anything, you know, I wanted to add my little signature."

Stern remained calm and collected by keeping him on the line to get as many incriminating answers as possible.

When asked about the timeline of his alleged killings, Clay said he hadn't murdered anyone in almost a year.

He was also asked if he ever considered taking his own life, replying: "If I killed myself, I'd miss the next Batman movie."

Clay added: "I really don't know, Howard. Part of it had to do with my car broke down.

"Well, that was the reason for a month, but after that, I guess it was all self-control."

The host then asked Clay if he still planned on killing women and was met with a harrowing one-word response: "Sure."

Clay went on to open up about how he was, apparently, abused as a child, and that he had a 'couple of kids' with a woman he isn't married to.

Viewers have since praised Stern for the way he went about the interview, as one person commented: "Notice how Howard was trying to ask the most incriminating questions possible. Age, look, race, location, any distinctive marks like tattoos or scars. So hopefully cops could get something from it. Smarter than he looks (and sometimes acts)."

Another admitted: "Don’t particularly like Howard Stern, but man, he nailed this. Getting this guy to feel comfortable while getting as much information from him as possible was seriously impressive."

While a third penned: "The guy called in because he's frustrated at the cops not figuring anything out. He needs recognition and excitement. He regrets not leaving clues like he always wanted to. He's asking to be caught in a way."

As someone else pointed out: "The scary part about this is the fact that people like Clay live among us. We probably cross paths with them everyday and NEVER realise it."

To this day, we still don't know who Clay is, or even if what he said he did is true.
