This is the first bodycam footage of convicted killer Chris Watts squirming after being confronted by cops on his return from burying the bodies of his pregnant wife and two kids.
Watts appears flustered and avoids eye contact as police quiz him about the disappearance of his wife Shannan who was reported missing by friend Nicole Atkinson.
Atkinson became worried after failing to hear from her friend for over 12 hours and realised that her car was still parked in the garage.
The footage was filmed by an officer from the Frederick Police Department who responded to the call at the family's Colorado home.
Unbeknownst to them, Watts had strangled his wife and buried her in a shallow grave and callously ditched the bodies of daughters, Celeste, 3, and Bella, 4, in an oil tank.
The 33-year-old sways from side to side as he is asked to check the home's surveillance footage in the hope that it could provide clues.
