Wife & Child Killer Chris Watts' Mistress Placed In Witness Protection Nichol Kessinger 'plans to start fresh with a new name,' a source claims.

Colorado family killer Chris Watts‘ mistress Nichol Kessinger was taken by federal authorities and placed in witness protection hundreds of miles away from home, RadarOnline.com can exclusively report.

“She has received several threats, public shaming and could be considered one of the ‘most hated women’ in America,” a source close to the investigation told Radar. “She plans to start fresh with a new name, new town and ultimately a new identity.”

Now, she is living in another state for her own safety, the source explained.

Just one month before Watts murdered his pregnant wife Shanann and two young daughters, Kessinger claimed he began an affair with her.

She has said she believed he was in the middle of divorcing his wife, but was a doting dad to Bella, 4, and Celeste, 3.

“He’s a liar,” Kessinger, 30, told The Denver Post in November. “He lied about everything.”

In an exclusive interview with authorities obtained by Radar, Kessinger told police she pushed him to fix his marriage— but he refused to do so.

Radar readers were first to know that Watts — who is serving a life sentence for murdering his family — is now rotting away in a maximum-security prison in Waupun, Wisconsin.
