Chris Watts gave disturbing excuse for murdering pregnant wife and daughters in chilling letter to fellow inmate

Warning: This article contains details some readers may find upsetting

Chris Watts branded his late wife a 'control freak' in a disturbing letter sent to a fellow inmate where he discussed the horrific murder of his family.

He brutally killed Shanann Watts - who was pregnant with his child - and their two daughters, Bella and Celeste, in Frederick, Colorado, in August 2018.

Watts is currently serving five life sentences for his horrific crimes, which he committed in the hopes of starting a new life with his mistress Nichol Kessinger.

The disgraced dad strangled Shanann to death before smothering the two little girls - aged just four and three - and dumping their bodies at the site of an oil and gas company.

Chillingly, Watts attempted to coverup the murders and even gave TV interviews begging for his family's safe return, before his web of lies was exposed.

The 39-year-old killer later confessed to taking the lives of Shanann, Bella and Celeste - although he dodged the death penalty.

He was sentenced in November 2018 and has been behind bars ever since - however, Watts hasn't stayed silent.

Instead, he has offered up graphic details of the murders to the likes of true crime author Cheryln Cadle, who published a book based on their correspondence in 2020.

And last year, it was revealed that Watts had also been discussing his crimes with fellow prisoners.

The murderer penned a number of letters to Dylan Tallman, who resided in the cell next to him at the Dodge Correctional Institution in Wisconsin, according to the New York Post.

He appeared to try and justify his vile actions in the handwritten notes, which were publicised last year.

In one, Watts toted himself as the primary caregiver to his and Shanann's two children, as he reportedly wrote: "She was really busy with her job and everything it required."

In another, he described how women had started giving him attention after he lost weight and started working out in 2017 - before he met Kessinger.

Discussing his mistress, he reportedly told Tallman: "She was just everything my wife wasn’t like with me. She was just nice, and not a control freak. We could make decisions together.

"We knew each other for awhile, but we didn’t start messing around until six weeks before. I was not thinking. We worked together, we had chemistry, and I fell into temptation. She was the forbidden fruit."

But Watts then said that Kessinger had later become 'the death of him', while it is claimed he branded her a 'harlot' and a 'jezebel' in another letter seen by the New York Post.

He is alleged to have added: "Her flattering speech was like drops of honey that pierced [my] heart and soul. Little did I know that all her guests were in the chamber of death.

"The lust of the eyes, the lust of the flesh and the pride of life...How did I not see it? The web of the enemy squeezes around my heart and is cocooning my soul to the point of suffocation."
