What Chris Watts told investigators about his murders of his family
[...]
CREATING AN ALIBI
After murdering his family and disposing of their bodies, Watts told investigators that he went back to his home and tried to make it look as if Shanann had taken their children and left him. According to Watts, he took Shanann's wedding ring and left it on a counter so it would appear as if she wanted to divorce him. He also said he tossed a book on therapy in the garbage to make it seem like Shanann thought their marriage couldn't be saved, the documents state.
WHY WATTS PLEADED GUILTY
After doing interviews with the media begging for his wife and daughters safe return, Watts told investigators that he
confessed and pled guilty so things would not drag out in court for years.
"I didn't want my attorneys to lie for me for two to four years ... They would've done anything I told them to do," he said. A few weeks after his arrest, Watts said he confessed to his attorneys that he killed his family. Watts told investigators he doesn't regret taking a plea deal, but had not thought
he would be in prison for the rest of his life.
HIS MISTRESS KNEW HE WAS MARRIED
According to Watts, Nichol Kessinger knew he was married with children —
something Kessinger denied. Watts told investigators that in June 2018, shortly after they met, he showed Kessinger a cellphone picture of Bella and Celeste, and Kessinger also saw a photo of Shanann on the lock screen of his phone. Watts said Kessinger denied knowing he was married to try and "save face."
Watts also told investigators that although Kessinger would get "pissed" when he would leave her to go back home, she never asked him to do anything to harm his family.
