Chris Watts murdered his pregnant wife and their two daughters.
Now, the family murderer Chris Watts is seen detailing the killing of his loved ones in a series of disturbing letters that were written from prison, and that's also where he shared how he required two attempts to murder his own kids.

Watts is seen explaining how he had plenty of thoughts about killing his wife for weeks. Notoriously, Watts killed his partner and smothered his two daughters. He subsequently buried Shannan at a work site roughly 40 miles away, before disposing of his daughter's bodies in crude oil tanks.
The crimes left residents and people around the globe in shock as they gained infamy, especially when a Netflix documentary on his crimes was made.

Watts tried to smother his daughter unsuccessfully before attacking his wife, saying his eyes filled with blood.
He described how he recalls her face getting all black with streaks of mascara. In the letter, he mentioned how on the morning of August 13, he went into the girls' rooms first before Shanann, and he had an argument. He used a pillow from the girls' room to kill them. Disturbingly, his daughters woke up and followed him around the home as he thought about what to do with his wife's body.

His wife was expecting at the time, also revealing how just one daughter tried to put up a fight against her killer dad, after realizing what he was trying to do. But she failed and was killed with the rest.
