Chris Watts is working as a custodian at maximum-security prison and has group of female pen pals who he’s revealed gory details of how he strangled his pregnant wife and smothered their two young daughters

The killer’s father, Chris Watts, is serving his time in a maximum security prison in Wisconsin, working as a jailer while exchanging letters with female pen pals.

On August 13, 2018, Watts strangled his wife Shanann — who was 15 weeks pregnant with their son — at the couple’s home in Frederick, Colorado. He later smothered their daughters, Bella, 4, and Celeste, 3.

The 36-year-old is serving five life sentences plus 48 years in prison without the possibility of parole at Dodge Correctional Institution in Waupun, Wisconsin.

Watts not only works as a custodian, he maintains active correspondence with several women, many of whom believe he is innocent, according to Inside edition.

“In my <3 you are a great guy," Candace writes. "If you wrote me back, I'd be the happiest girl in the world, that's for sure." She highlighted the note with "#TEAMCHRIS," "#CHRISISINNOCENT," "#ILOVEHIM," and "#TOOCUTE."

“In my <3 you are a great guy," Candace writes. "If you wrote me back, I'd be the happiest girl in the world, that's for sure." She accented the note with "#TEAMCHRIS," "#CHRISISINNOCENT," "#ILOVEHIM," and "#TOOCUTE."

In just a few weeks in jail, Watts received nearly 60 letters from complete strangers expressing both love and hatred for the killer.

Kim told Watts she was “hoping to brighten up your days,” while Hannah said, “I feel this connection with you.”

Women have written to Watts in the past, with the killer even sharing the gory details of the murders.

Cherlyn Cadle appeared on a new episode of Lifetime’s Cellmate Secrets to share personal details from letters she exchanged with Watts.

Cadle, a Midwestern author and grandmother of 12, claimed the murders were premeditated based on what he told her from behind bars.

“He told me he’d be daydreaming about Shanann’s murder,” Cadle said. “She’d yell at him or be upset about something and he wouldn’t fight back, but he’d just stand there daydreaming about what it would be like to kill her.”

said Cadle Fox news she wrote to Watts in prison after watching his first interview on TV.

Many of the women sighed their letters with hearts and x’s and o’s

Cadle wrote her first letter to Watts in February 2019. In a matter-of-fact tone, she explained her intentions to write a book and said she never doubted his guilt. Eventually they built up a correspondence, with Watts telling her about his life and the murders. Pictured: Watts writing to Cadle in April 2019

“When I saw his first interview, I don’t know, I looked at him that morning and I felt something was really speaking to me,” she said. “It was like a call for me to reach out to him and see if he would share his story with me.”

“I knew he was guilty. You could see it in the way he talked, in the body language,’ Cadle added. “But it was just one of those things that I really felt like I had to do.”

Watts finally replied to Cadle after her third letter in early 2019.

“He was receptive from the very beginning,” Cadle recalls. “He said God told him to respond. I guess because I was a mother and grandmother, he didn’t feel any threat.’

When Watts sent her a 12-page letter detailing each murder, Cadle immediately became emotional.

“I just broke down and started bawling,” Cadle admits. “I cried and cried. I just couldn’t believe what he had done to those girls… It was a real shock to read his letter.’

“I knew in my heart at that moment that this was the real and true confession. He said it was planned right away,” she added. “It was premeditated. And he wanted to wipe the slate clean. He wanted to start over. He didn’t want to bring any baggage into the new relationship. And there was a hefty insurance policy… That changed everything for me.”

Calde also said that Watts was already “getting a lot of fan mail from women sending him pictures of themselves in bikinis” who said they loved him.

After exchanging several letters and talking to him on the phone several times a week, Cadle agreed to meet Watts in jail.

“I hate to admit it because he’s a killer and what he did is so horrible, but when I first met him he had this boyish attitude,” she said. “He was gentle, soft-spoken, and just came across as a nice guy. And he remained so throughout our communication. That changed when he started talking about the murders.’

It appears that Watts did not write back to any of the other women based on follow-up notes from some of the senders, who often attached more photos and expressed their love for the felon and belief that he was innocent of all crimes.

Watts killed Shannan after she came home from a business trip to Arizona in 2018.

He strangled her in bed and packed her body and their two daughters into his truck and drove to isolated oil storage tanks belonging to Anadarko Petroleum, where he worked.

He buried his wife in a shallow grave and then smothered his two daughters and placed their bodies in the holding tanks.

For two days, Watts claimed he had nothing to do with his family’s disappearance and went on television to beg them to come home.

After his arrest, he initially claimed that Shanann killed the girls after telling her he wanted a breakup, then strangled her in a rage.

At his trial, he pleaded guilty to avoid the death penalty, which has since been abolished in Colorado.

He is serving five life sentences plus 48 years in prison without the possibility of parole at Dodge Correctional Institution in Waupun, Wisconsin.
