Chris Watts, the father who murdered his wife and two young daughters after having an affair with his co-worker is still in touch with his mistress, he has claimed from jail.
In August 2018, Watts, 35, killed his pregnant wife Shanann at their home in Frederick, Colorado, and put her body in his truck.
He took their two daughters Bella, 4, and Celeste, 3, with him out to a remote worksite owned by Anadarko Petroleum - the oil company that he worked for - and dumped Shanann’s body in a shallow grave.
He then smothered his daughters one at a time and put their bodies inside oil storage tanks.
The disturbing case made worldwide headlines and later became the subject of Netflix documentary American Murder: The Family Next Door.
Watts is currently in Dodge Correctional Institution in Waupun, Wisconsin, where fellow inmate David Carter revealed the killer dad is still in touch with the woman he murdered his family for.
Nichol Kessinger, who changed her name and moved away from Colorado after the murders, reportedly wrote to Watts under a new identity.
“He told me she said that she needed to speak to him to clear some things up,” Carter told DailyMail.com. “He wouldn't tell me exactly what she had said.”
Carter said Mr Watts first told him he was communicating with his former lover in September last year.
He said prison authorities discovered the letters and punished him by suspending his mail accounts and monitoring his letters, Daily Mail reported.
“He wasn't supposed to have any contact with her, but she initiated it by writing to him,” Carter said.
Watts and Kessinger met while working together at Anadarko and their affair lasted just over a month before he was found guilty of his family’s murder.
Watts’ letters from jail go viral
Gruesome letters penned by Watts from his prison cell were published in 2019 in Letters From Christopher, a book written by author Cheryln Cradle after she struck up correspondence with him.
In one of the letters shown to Daily Mail TV, Watts revealed the moments leading up to his family’s death.
“August 13th, morning of, I went to the girls’ room first, before Shanann and I had our argument,” he wrote.
“I went to Bella’s room, then Cece’s room and used a pillow from their bed (to kill them). That’s why the cause of death was smothering. After I left Cece’s room, then I climbed back in bed with Shanann and our argument ensued.
“After Shanann had passed, Bella and Cece woke back up. I’m not sure how they woke back up, but they did. Bella’s eyes were bruised and both girls looked like they had been through trauma.”
According to Daily Mail TV, he also admitted to giving Shanann Oxycodone unbeknownst to her to try and cause her to miscarriage.
In the moments before Watts killed his wife, he told her he did not love her anymore.
“Isn’t it weird how I look back and what I remember so much is her face getting all black with streaks of mascara?” he wrote in the letters.
“All the weeks of me thinking about killing her, and now I was faced with it. When she started to get drowsy, I somehow knew how to squeeze the jugular veins until it cut off the blood flow to her brain, and she passed out.
“I knew if I took my hands off of her, she would still keep me from Nikki. They asked me why she couldn't fight back, it's because she couldn't fight back. Her eyes filled with blood; as she looked at me and she died. I knew she was gone when she relieved herself.”
Watts is serving five life sentences plus 48 years without the possibility of parole.
