Krystal Lee Kenney, Who Assisted Patrick Frazee's Murder Of Kelsey Berreth, Denied Early Release

The former lover of Patrick Frazee, the man convicted of murdering his fiancée, Kelsey Berreth, in 2018, was denied a request to be released from prison early.

Krystal Lee Kenney, 33, requested an early release in March — just two months into her three-year sentence for her role in Berreth's killing. While her request was just denied, she can be reconsidered for it again in as soon as six months, CBS 4 in Denver reported Wednesday. 

Kenney, who worked as a nurse in Idaho at the time of Berreth’s killing and had an intimate relationship with Frazee while he was engaged to Berreth, was the star witness in Frazee's trial. She testified that she traveled to Colorado upon Frazee’s beckoning after he murdered Berreth, 29, with a baseball bat at the home he shared with her.

She said she brought cleaning supplies, a body suit, and foot covers to assist Frazee in cleaning Berreth’s home. Kenney testified that there was blood splattered everywhere, including all over baby items and toys, according to an affidavit obtained by the Denver Channel. Berreth and Frazee had a daughter together, who was just an infant at the time. The baby was in the home during the killing.

Kenney then disposed of Berreth’s cellphone on Frazee's behalf in Idaho. Additionally, Kenney admitted that Frazee had asked her to help him kill Berreth three times prior, plans that Kenney helped concoct. In one murder plot, the pair planned to poison a caramel macchiato drink and give it to Berreth to drink. 

Kenney's short sentence was the maximum amount of prison time she could get due to an extremely generous plea deal prosecutors gave her for her role in Berreth’s killing, which one official described as a "deal with the devil." She had pleaded guilty to a count of tampering with crime scene evidence.

“Ms. Kenney deserves to spend every day of her three-year sentence in the Department of Corrections, but we are cognizant of the fact she will not serve that entire sentence, day for day, in the Denver Woman’s Correctional Facility,” the 4th Judicial  district attorney’s office wrote in a March letter obtained by the Denver Channel. “She should, however, serve more than two months. She should serve her full sentence in the DOC until she paroles from DOC. Serving two months out of a three-year sentence for what she did is simply unconscionable.”

If it weren’t for Kenney’s plea deal, she could have faced up to 100 years behind bars. 

“We did a deal with the devil,” 4th Judicial District Attorney Dan May said earlier this year, Denver CBS reported. “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.”

Frazee was sentenced to life in prison without the possibility of parole — plus 156 years — for killing Berreth. The mother's body has never been found. 

Berreth and Frazee’s daughter is now in the custody of Berreth’s parents. The story of Berreth's murder will be documented in the upcoming season premiere of the Oxygen series "Killer Couples."

The next season of "Killer Couples" premieres on Oxygen on Thursday, June 18 at 8 p.m.
