Chris Watts’ daughter had devastating final words before being murdered by her father in 2018.

The father-of-two is currently serving five life sentences after killing his pregnant wife, Shanans Watts and their two children, Bella, 4 and Celeste, 3 in Frederick, Colorado in August 2018.

The murders rocked the world due to their horrific nature, after authorities discovered that Watts not only murdered his entire family but also disposed of his daughters’ bodies in an oil tank and their mother in a shallow grave, nearby.

Shanann’s parents asked that the prosecution not seek the death penalty and rather that Watts receive five life sentences, three of which are consecutive.

As reported by the Mirror US, the 39-year-old confessed that he strangled his pregnant wife and his two young children, who were begging for their lives.

In letters he wrote years later, Watts admitted that he attempted to give his pregnant wife OxyContin to kill the baby growing in her womb and they he had thought about murdering her for ‘weeks’.

He had been involved in an affair that same summer and later claimed the crimes began after his wife told him she knew about it.

ABC News released a report in February 2019 that Watts admitted he didn’t love her, which caused his wife to say “You’re never gonna see the kids again.”

He proceeded to strangle her at home with both his hands, which he later said; “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?

“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,”.

He admitted that she did not struggle and that their daughter Bella walked into the room and asked  “What’s wrong with mommy?”.

The report from the Colorado Bureau of Investigation claimed that Watts put his children in the back of his truck with Shanann’s body on the floor of the truck bed. He proceeded to drive to the oil site where he worked and admitted to authorities that his daughters fell asleep in each others laps.

One he buried his wife, his daughter asked him “What are you doing to mommy?” – to which he claims to have forgotten what he replied.

Using his daughter Celeste’s Yankees blanket, he strangled her to death while Bella stayed silent. He then brought her body to the oil tank, where Bella asked “Is the same thing gonna happen to me as Cece?”. Her last words were “Daddy, no!”.

The killer claims that he still hears those two words everytime he closes his eyes.

He later revealed that he intentionally left his wife’s wedding ring on the kitchen counter, to give the appearance that she wanted a divorce.

He also admitted that in August 2018, he lied to reporters. Watts claimed: “When I came home and then walked in the house, nothing. Vanished. Nothing was here.

“My kids are my life.” he said at the time.

After days, the bodies were found and he was arrested.

While being interviewed, he admitted that he could not admit what he had done to himself or the police. He also claimed that he did not think about claiming his wife killed their children until it was mentioned to him later.
