Chris Watts’ mistress applies to change her name two years after he killed family

The mistress of cold blooded killer Christopher Watts has applied to change her name, two years after coming forward to confess they’d been having an affair.

Nichol Kessinger helped police with their investigation after Watts was arrested for the murder of his pregnant wife and two daughters.

Kessinger told officers as much as she could about the man she’d been having a relationship and Weld County District Attorney Michael Rourke has since said the information she gave them was “bombshell”.

Now Nichol, 32, has applied for a name change in Jefferson County, Colorado. A hearing has been set for Thursday, according to the Daily Mail.

The request comes after Netflix’s documentary American Murder: The Family Next Door was released last month.

It has become one of the most watched programmes on the digital streaming service.

In the documentary, Kessinger told police officers that Watts had said his marriage was over, and that she had no idea his wife Shanann, 34, was pregnant.

A week before Watts carried out the brutal murders, Kessinger’s phone records showed she had spent over an hour online searching for wedding dresses.

On Watts’ phone, semi-naked pictures of Kessinger were found, hidden in a password protected calculator app.

After the murders, Kessinger spoke with investigators for nearly two hours.

She said she had decided to come forward after ending her relationship with Watts because of the lies he had been telling her for the past eight weeks.

In late 2018, it was reported Kessinger had moved from Colorado to another state, started a new job and was placed in the witness protection program.

To the outside world, Watts seemed like the perfect father and devoted husband and appeared to be delighted that his wife was expecting their third child, a boy they had planned to call Nico.

But what devoted Shanann didn’t know was that her husband was cheating on her and hatched a twisted plot to kill his wife and children.

It was when Shanann returned to the family home in Colorado following a business trip that Watts set his plan into motion.

Shanann and her husband had a huge row when he confessed to his affair and in the heat of the moment she told him that she would have full custody of their children.

In cold blood Watts then strangled his wife to death – but his brutal actions were witnessed.

After Watts murdered her mother and was wrapping Shanann’s body in a blanket, little Bella walked into the room and asked “what are you doing to mummy?”

The four year old, who was said to be bright for her age “knew something was up”, according to Mr Lambert.

What happened next was truly chilling. Watts bundled Shanann’s body into the boot of the family car, put his two little girls in the backseat and belted them in.

The murderous father then drove 45 minutes to an oil field before carrying out the second part of his horrifying plan.

During the journey, Bella is said to have pleaded with her dad to take 34-year-old Shanann to hospital.

When they arrived at the oil field, Watts smothered Celeste with her favourite blanket. Bella witnessed the murder and begged her father not to kill her before trying to run away.

Watts then buried his wife in a shallow grave before disposing of the bodies of his two daughters in an oil tanker. He then returned to the family home and reported all three of them missing.

The killer even gave interviews to the press, pleading for his family to come home and claiming he had no clue where they had gone.

Watts even sent his wife text messages, asking her where she was, after he had killed her.

But the net was rapidly closing in on the killer father and within days he had failed a polygraph test and would then spend the rest of his life behind bars.

Watts has never revealed any details about how he killed his whole family and as he pleaded guilty, the details didn’t come out in court.

However, as soon as it emerged what Watts had done, Nichol was horrified and did everything she could to help police.

She told officers about all the lies he had told her when she thought they were a couple.

Nichol explained: “It’s not fair. It wasn’t fair to me in the first place, it wasn’t fair to her in the first place, it wasn’t fair to any of us in the first place.

“It wasn’t fair to his family for him to have an affair, it wasn’t fair to me to have him lie to me and make me think that everything is going to plan. And still to this day, I don’t even know what’s a lie and what’s not.

“It’s like, you know, I’m gonna wake up every day and know that like this mom and her unborn child and these two little girls are not around anymore and it breaks my heart.”

Watts is currently behind bars in Wisconsin, US, after being sentenced in November to five consecutive life sentences with no chance of parole.

He was only spared the death penalty because he pleaded guilty to all the charges against him.
