Chris Watts

Two women who have been visiting Chris Watts in prison have said that he felt "an evil spirit" took over him when he killed his wife and children.

Cindy Watts will read aloud a letter from his son in an HLN special entitled "Killer Dad: Chris Watts Speaks."

Nancy Grace compared Chris Watts killing his pregnant wife, Shanann, and their children to a Rubik's Cube in an attempt to explain the public's fascination with the case.

“The ripple of one crime like this has been phenomenal. ... Some of the investigators I know had struggled to return to their jobs and go about investigations the same way," Steve Wrenn, the Deputy District Attorney for Weld County said.

Chris Watts was sentenced to prison after murdering his pregnant wife, Shannan, and his two young daughters, Bella and Celeste.

Nearly 16,000 people signed on to a petition demanding prison officials not allow Watts to keep photos of the pregnant wife and two young daughters he murdered with his bare hands.

Chris Watts was sentenced to life in prison for killing his pregnant wife, Shannan, and their two daughters, Bella and Celeste, with his bare hands.

"I knew. I swear to God I knew. ... I woke up the whole house. I said, 'Something's wrong with Shanann,'" Sandy Rzucek said of the day her daughter was murdered. 

“I didn’t feel like I deserved to live after what happened," Chris Watts said, speaking of his murders of wife Shanann and daughters Bella and Celeste.

“Honestly, I never even thought about that story until you guys mentioned it,” Watts said of his initial story that he only killed Shanann after she smothered their daughters.
