Chris Watts' Mistress Said He Claimed His Wife's Baby Was Not His

"Nichol [Chris Watts' mistress] said he was playing like he did not know Shanann was pregnant, even though she was 15 weeks pregnant,” according to recently released documents in the case.

Chris Watts’ mistress told police that he revealed to her that his wife’s baby wasn’t his, according to newly released records.

Watts was sentenced last week to life in prison without parole for each of the three murders he confessed to committing back in August: His wife Shanann, 34, and daughters Bella, 4, and Celeste 3. The three sentences will run consecutively. He was also given 48 years for the life of the unborn child that Shanann was 15 weeks pregnant with.

In the days after the sentencing, the Weld County District Attorney released approximately 2,000 pages worth of documents detailing the case, including interviews with Nichol Kessinger, a coworker with whom Watts had struck up a romantic relationship.

Last week, during Chris Watts’ sentencing, prosecutor Michael Rourke said a future with Kessinger was the motive behind the killings: “Why did this have to happen? [Watts]' motive was simple, your honor. He had a desire for a fresh start.”

The newly released documents, published in full in the Denver Post, show how Shanann Watts tried desperately to save their marriage. She pleaded with Chris Watts to talk about their relationship and for affection.

Meanwhile, Chris Watts was telling Kessinger a totally different story.  

Kessinger told police that Chris said to her that Shanann Watts did not have any interest in working on their marriage.

Moreover, he even hinted that she may have been cheating on him and that she may have confessed to cheating the day of her death.

“He [Chris Watts] said she woke up [on the morning that Shanann and the kids went missing] and they got into an argument and she [Shannan Watts] was being pretty mean,” the newly released documents state. “She [Shannan] told Chris that she is pregnant and said the kid was not his. Nichol said he was playing like he did not know Shanann was pregnant, even though she was 15 weeks pregnant.”

Just days before the murders, according to the documents, Kessinger searched on Google for wedding dresses “for over two hours.”

Later, she admitted to being deceived by the husband-turned-convicted-killer.

“He’s a liar,” she told the Denver Post earlier this month. “He lied about everything.”
