Chris Watts became a national symbol of betrayal when he murdered his pregnant wife Shanann and their two young daughters in August 2018. In the days and months that followed, details emerged about a coworker with whom Watts had been having an affair. This woman became widely described in media and public discussion as his mistress. This overview provides a neutral summary of who she was, the nature of the relationship, and how it intersected with the crimes and their consequences.
Identity and background
Public records and credible news reporting from the period identify the woman as Katherine McKee, who worked with Chris Watts at Anadarko Petroleum in Colorado. She was in her late twenties at the time of the murders and lived in the same community as the Watts family. Her interactions with Watts before and after the killings became material to understanding his motive and opportunity.
Timeline of the relationship
Court documents, testimony, and interviews trace the affair to months before the murders. Watts pursued the relationship while married, which added to the financial and emotional pressures he faced. Testimony indicated that on the night of the crimes, communications between Watts and McKee were active, and she was among the first people he contacted after the killings. The timeline below summarizes key documented points of contact.

During the trial, the prosecution framed the affair as both a motive and a logistical element in the planning of the murders.

Her decision to cooperate with investigators and later testify against him proved pivotal in the jury’s deliberations.

Public perception and media coverage
From the outset, outlets and commentators referred to her as Chris Watts’s mistress, often emphasizing the emotional betrayal alongside the crimes. Coverage varied between factual reporting on her role as a witness and more speculative commentary about her involvement. Public attention on her identity and statements remained high through the trial and initial sentencing phases.
Privacy, safety, and ongoing interest
Following the trials, McKee returned to relative privacy, though she remained a fixture in broader discussions about the case due to her direct involvement. She moved to a new location and took measures to protect her privacy and safety. Interest in her identity persists because of the unresolved questions around motive, loyalty, and the full scope of communication between her and Watts.
Current status and frequently asked questions
As of the latest available information, Katherine McKee continues to live privately and has not published a memoir or major public statement about the case. Clarifying common questions helps separate verified details from speculation:

Broader context and takeaways
The relationship between Chris Watts and Katherine McKee is one element within a larger case that exposed family violence, planning, and the limits of personal trust. Her presence complicates simple narratives, highlighting how motives, opportunities, and emotional dynamics intersect in extreme crimes. For observers, the enduring interest in her identity speaks to a broader public curiosity about how ordinary relationships can collapse into horrific acts.
Reliable details remain limited, and much about her thoughts and actions will likely remain private. What is documented shows a woman who was both involved in a criminal concealment and a key witness whose cooperation influenced the outcome of a high-profile trial. Understanding her role—and the boundaries of what is known—helps ground discussion in verified information rather than speculation.
