A new report shows that Christopher Watts was actively having an affair in the time before he murdered his wife.
Watts told investigators that he told Shanann he wanted a separation. He claimed that moments later, he saw, on the baby monitor in his bedroom, "Bella 'sprawled' out on her bed and blue and Shanann actively strangling Celeste."
At that point, Watts said, he "went into a rage" and strangled his wife to death. He told police that afterwards, he put the bodies of his wife and two daughters into his work truck and took them to an oil site.
Watts said he buried Shanann's body near two oil tanks and dumped Bella and Celeste's bodies inside of the oil tanks, according to the affidavit.
