Chris Watts plotted to kill family at a birthday party then fed and showered girls before murders | Daily Mail Online
Watts had taken the girls to a birthday party on the afternoon of Sunday, August 12, and while Bella, 4, and Celeste, 3, played in the pool their father started texting co-worker Kodi Roberts.
At 5.06pm that evening, Watts set in motion his plan for disposing of his wife and daughters' bodies, as he texted Roberts that he would be making the drive out to one of the more distant oil fields that was managed by his company, Anadarko Petroleum Corporation.
Shanann's father was one of the last people to see the girls, revealing he spoke to them on FaceTime on Sunday evening.
Frank Rzucek stated in an interview with law enforcement officials that he spoke with both Watts and Bella, who was eating cold pizza and candy.
A babysitter, who was the sister of the birthday boy whose party Watts and the girls attended that Sunday, also spoke with an agent with the Colorado Bureau of Investigation.
She said that on Saturday Watts had asked her to watch the children while he attended a Rockies game, though it was later revealed that he was actually on a date with his mistress, Nichol Kessinger.
It was her first time babysitting for the family, with the normal sitter who is a close friend of Shannon's not called in for reasons that are not stated in the reports.
The babysitter did have a different version of events as to what happened the following day though, saying that Watts left the party much earlier than he told authorities.
'[The babysitter] stated the following day, Sunday August 12, 2018, Chris, Celeste and Bella came to her home for a birthday party for her younger brother,' reads the CBI report. 'Celeste and Bella are friends of her younger brother. [The babysitter] recalled Chris and his daughters left her home at about 3.30pm.'
Watts' co-worker Roberts later told an agent with the Colorado Bureau of Investigation that it was 'unusual' that Watts had texted him on a weekend, and stated that he did arrive to the site alone on Monday morning.
