Chris Watts Update: Convicted Killer Blames Former Mistress Nichol Kessinger For Murders

In a new HLN special called "Lies, Crimes, & Video," details were released surrounding the 2018 murders of Shan'ann Watts and her children, Bella, Celeste, and Nico.

According to Cafe Mom, one part of the documentary involved interviews with women who frequently travel to visit convicted Colorado killer Chris Watts behind bars. One of them, who calls herself "Anna," revealed a particularly unusual claim that Watts' mistress, Nichol Kessinger, was the one who was actually responsible for the murders.

"Chris feels that if the affair would have never happened and [Kessinger] would have never came into his life, that the murders would never have happened," the visitor said.

Continuing, she added, "He thinks that she had this strong control over him, that he describes like a 'leash' that he wasn't able to get off or get away from, and he thinks that that has played a role in what happened."

This sentiment echoed what Watts had previously said during recorded footage regarding the confrontation with Shan'ann about the affair. Eventually, he said that the conversation turned towards divorce with her telling him that he was "never going to see the kids" again. According to "Anna," Watts then snapped as he felt like he was "demon-possessed."

"Every time I think about it, I'm just like, 'Did I know I was going to do that before I got on top of her?'" Watt said in a prison interview earlier this year, adding, "I don't even want to say it felt like I had to. It just felt like there was already something in my mind that was implanted that I was gonna do it and when I woke up that morning it was gonna happen and I had no control over it."

Despite now calling himself a "changed man," Watts is currently serving five consecutive life sentences in a Wisconsin prison.
