Following the 2018 disappearance of his family, Chris Watts agreed to do a televised interview in order to ask for the safe return of his wife, Shanann, and their two children, Bella and Celeste. Swaying back and forth on his porch with his arms crossed, he pleaded that they "just come back."

Ultimately, the Frederick, Colorado, resident confessed to murdering all three members of his family and was sentenced to life in prison without parole. However, before his admission, Watts additionally exhibited other "significant signs of deception," according to a body language expert who spoke to Oxygen.

When Watts was initially called by law enforcement and alerted to the fact that his family was missing, he made his way back to his residence. However, upon arrival, he made police wait outside his home for more than a minute as he went inside alone. Following their entrance, Watts then walked away from the door. In contrast, Shanann's friend, Nickole Atkinson, and officers went into the home to begin investigating the mystery surrounding their whereabouts.

"It means that he is separating himself from what is being spoken at that time," revealed body language expert Susan Constantine.

After the group finally came inside the home, Watts went on to discuss his wife's migraines with police. This, according to Constantine, was another red flag.

"These are things that he just seems to be filling the air with some biographical information, but he's still not panicking. His daughters are missing and Shanann is missing and he's just providing with some, in my opinion, useless information that goes nowhere," stated homicide prosecutor Jarrett Ferentino in the Reelz special, "Capturing Chris Watts."

Ferentino also noted that while Watts was watching footage of himself backing his truck into his driveway at 5:15 a.m. on the morning his family disappeared he continued to draw attention to himself. As the video played, he placed his hands on top of his head, moves back and forth, and looks away. "He's afraid to look at it because of what it might reveal, so part of it is deflection, right?" asked Constantine.

Watts eventually left the room, which prompted his neighbor and the owner of the footage to say that he wasn't "acting right at all."

As for how the convicted killer is taking to prison, people have reportedly said that he is "in his own private hell" while he serves his sentence. However, he continues to receive weekly female visitors. As for Shanann's family, they recently asked for all of the "cruel" and "heartless" online harassment to stop following the horrific crimes.
