Patrick Frazee Guilty Of 1st Degree Murder In Kelsey Berreth's Death

TELLER COUNTY, Colo. (CBS4) - The jury has convicted Patrick Frazee of first-degree murder in the killing of Kelsey Berreth. Jurors began deliberating the case on Monday morning.

Prosecutors believe Berreth was murdered in her Woodland Park home in Colorado. She was last seen on Thanksgiving Day 2018 on security video at a grocery store. Her body has not been found.

Prosecutors insist Frazee is guilty of first-degree murder by killing the mother of their 2-year-old child with a baseball bat. They also say that Krystal Lee, Frazee's on-again, off-again girlfriend, claimed Frazee tried three times to get her to murder Berreth and then he said he killed her himself in Berreth's home.

"We did a deal with the devil, and I'm not proud of that, but Kelsey wouldn't have had justice today without making that deal with the devil," said Dan May, 4th Judicial District Attorney.

CBS4 Investigator Rick Sallinger was in the courtroom for the verdict and said that Frazee showed no emotion as the verdict was read.

Jurors asked a question of the judge just before 1 p.m. and requested to see a still frame picture from a security camera of Frazee at Berreth's condo.

Frazee was convicted of all counts, including first-degree murder, three counts of solicitation to commit first-degree murder, and tampering with a deceased human body. He was also convicted on two sentence enhancers for violent crime, one resulting in death and the other for using a weapon.

"She did not deserve this. Today at sentencing, her family and her friends took the time not to attack Frazee, but to want the world to know who Kelsey was. Kelsey was a kind wonderful person," said May.
