A woman has come forward describing herself as a secret mistress of Chris Watts, the Colorado man convicted of murdering his pregnant wife and two young daughters in 2018, saying there is much she never disclosed to police at the time. She claims to reveal previously undisclosed details of their relationship, including explicit text messages and Watts' behaviour and comments about his wife, adding fresh perspective to one of America's most notorious domestic murder cases.

The full substantive detail of her account was not accessible in the supplied article text, which consisted largely of website navigation and formatting elements rather than the report's content. The case itself centres on Watts, who in 2018 murdered his wife Shanann and daughters Bella and Celeste in Frederick, Colorado, and is serving multiple life sentences; reports of additional mistresses beyond his previously known affair have periodically resurfaced in coverage of the case.
