‘My Punishment Comes Every Day’: Mistress Sentenced For Role In Kelsey Berreth’s Murder

Patrick Frazee’s mistress has been sentenced for her pivotal role in the murder of Frazee’s fiancée, Kelsey Berreth.

Krystal Lee Kenney, 33, was sentenced Tuesday, January 28, to three years behind bars, local outlet KKTV reports. That’s the maximum amount of prison time she could get due to a generous plea deal prosecutors gave her for her role in Berreth’s killing. She will also serve one year of mandatory parole.

“I am sorry that Kelsey’s friends and family will live the rest of their life without her,” Kenney said in court before her sentencing, NBC News reports. “I am sorry Kaylee has lost her mother. I am sorry that I did not save Kelsey.”

She went on to say, "My punishment comes every day.”

Kenney pleaded guilty last year to tampering with evidence in a bargain dubbed a “deal with the devil” by 4th Judicial District Attorney Dan May, Denver CBS reported.

“We did a deal with the devil,” May said. “There’s no ifs, ands, or buts about that. And I’m not proud of that. But there’s no question that Kelsey wouldn’t have had the sure justice today without making that deal with the devil.”

The plea deal meant she dodged more serious charges which could have resulted in up to 100 years behind bars, Denver CBS reports.

Kenney, who worked as a nurse in Idaho, was the star witness in Frazee's trial, and her testimony heavily impacted his conviction. She testified that she traveled to Colorado upon Frazee’s beckoning after he murdered Berreth, 29, on Thanksgiving 2018.

She brought cleaning supplies, a body suit, and foot covers to assist her lover in cleaning Berreth’s home after he beat her to death with a baseball bat. Kenney testified that there was blood splattered everywhere, including all over baby items and toys, according to an affidavit obtained by the Denver Channel. Kenney then disposed of Berreth’s cellphone for Frazee in Idaho.

Kenney has also admitted that Frazee had asked her to help him kill Berreth three times prior, plans that Kenney was a part of, CNN noted. In one murder plot, the pair planned to poison a caramel macchiato drink and give it to Berreth to drink.

A letter written by Berreth's parents, Darrell and Cheryl, was read in court Tuesday, which stated, “she [Kenney] was an active participant in the murder. The only thing she didn't do was swing the bat."

However, the letter did acknowledge that Kenney’s testimony helped their daughter’s killer get convicted, but noted she "revealed the truth only to save herself.”

During Frazee’s trial, his lawyers questioned Kenney’s reliability as she didn’t alert the authorities over the prior three alleged murder plots and had initially lied to the FBI, KRDO in Colorado Springs reported.

Frazee was sentenced to life in prison without the possibility of parole, plus 156 years, for killing Berreth. He has filed a motion to appeal that conviction this month.

Berreth’s body has never been found. Berreth and Frazee’s daughter are now in the custody of Berreth’s parents.
