See below for timeline details.

This is most of the police bodycam footage that Chris Watts appears in (and some additional footage) the day Shannann, Bella and Celeste Watts were reported missing, August 13th, 2018. Footage is in chronological order from morning to afternoon. The footage from this day alone (before Watts eventually admitted he killed his family) you can see signs that something is off with the story Watts was telling the police. Some points of interest/suspicion I listed in the timeline of the video and below:

Beginning:
Nikole Atkinson, Shanann Watts' friend, calls police after she can't get in contact with her and thinks something isn't right. Police become aware of the matter, walking the perimeter of the house and wait for Chris to get home.

Chris arrives 17:42
Chris gets home from work. (we now know he was discarding Shanann, Bella and Celeste's dead bodies at the oil site just hours earlier).

Phone 22:54
Shanan's phone is found in the house.

Wedding Ring 34:40
Chris shows a police officer Shanann's wedding ring, claiming she left it there (we now know he took it off her corpse and was hoping to play it off as she left it herself).

Surveillance 45:00
Chris' neighbor shows a police officer surveillance footage from the early hours of the morning of Chris pulling his truck back into his garage. No sign of Shanann or the kids leaving the house was on the footage. (we now know this is when he was loading up the dead bodies of his family, before discarding them at the oil site).

Medication 1:22:43
Nikole Atkinson finds Shanann's medication is her bag, which like her phone, and the bag itself, is not something she would leave the house without.

Bedroom 1:49:40
A police officer finds it suspicious that a bed sheet is missing from their bed. (which we now know Chris wrapped her up in before burying her in a shallow grave.

Chris 2:04:23
More interaction with Chris and officers.
