Chris Watts' decision to finally share the details of how he killed his pregnant wife and two daughters likely was due to "the jailhouse religion," a lawyer for the family of his deceased wife claimed. Earlier this week, gruesome details of the Colorado Watts family homicide case were made public during an episode of Dr. Phil's show.

"We don't believe that he has been offered anything, or that here is anything that could be given to him or traded," one of the lawyers said about Watts decision to speak with authorities, according to Daily Mail. "So I think it is the jailhouse religion. Our understanding is that he is now remorseful, and he's found God."

Watts, who was married to Shanann for six years, was serving three life sentences for murdering his family. 

Steven Lambert, the head attorney for Shanann's family in the wrongful death lawsuit, said he was shocked by the admitted murderer's demeanor. 

"We've had a few different conversations with him. It's almost eerie how normal some of the conversations go with him, and I don't know exactly what that's about or anything," Lambert said. "He's been very forthcoming. It's almost like calling a neighbor."

Watts killed his pregnant wife and two young daughters after an argument with his spouse on Aug. 13, 2018. Watts had told his wife he was having an affair and wanted a divorce.

“The night in question, Shanann came home,” Lambert told Dr. Phil McGraw. “She and Chris got into a fight. They had made up, they were getting along quite well.”

“Later on, they got into a fight again,” Lambert continued. “In that fight, he essentially confessed to having an affair, that he wanted a divorce, that it was pretty much over between them. She said something to the effect of, ‘Well, you’re not going to see the kids again.’ As a consequence of that conversation, he strangled her to death.”

“Bella walked in and asked, ‘What are you doing with mommy?'” Lambert said.

After killing his wife, Watts smothered his two daughters, Bella and Celesteir, and dumped the children’s bodies in an oil tank where they were found three days later.

“From our understanding, Bella did not witness the actual killing of her mother, Shan’ann,” the legal representative told Dr. Phil. “It was not until Chris was in the process of trying to dispose of Shan’ann’s body, essentially wrapping her up in this sheet.”

According to Lambert, Bella saw Watts smother her three-year-old sister Celeste with her favorite blanket, which caused the little girl to say to her father, “‘Please daddy, don’t do to me what you just did to CC,’” Lambert said. “He killed Bella,” he added.
