Patrick Frazee, the fiancé of missing Woodland Park mother Kelsey Berreth, was jailed Friday in connection with her death even though authorities have not found the woman’s body.

Woodland Park Police Chief Miles De Young said investigators recovered enough evidence at Berreth’s home to convince a judge to sign an arrest warrant. Frazee is being held for investigation of first-degree murder after deliberation and solicitation to commit first-degree murder.

“Investigators have recovered items at Kelsey’s residence to make us believe the crime happened there,” De Young said. “As you can tell from the arrest, sadly, we do not believe Kelsey is still alive.”

A solicitation charge means someone else was contacted to assist in the murder, but Frazee remained the only person who had been arrested as of Friday evening. To be charged with solicitation, the suspect did more than just ask someone to commit a murder on their behalf, said Fourth Judicial District Attorney Dan May.

May said there was an “absolute possibility” someone else could be charged in the case.

He declined to provide more details about what the solicitation charge entailed in Berreth’s disappearance.

Frazee, 32, appeared in Teller County District Court on Friday afternoon via a video feed from the county jail. He was advised of the charges, and his next court appearance was scheduled for 8:30 a.m. Dec. 31.

Frazee is being represented by a public defender, according to Teller County District Court documents. That lawyer filed motions Friday asking police to preserve all evidence including handwritten notes, audio and video recordings, and asking the court to limit pretrial publicity.

Judge Linda Billings Vela signed an order requiring the district attorney to preserve all blood, tissue and body fluids collected during the investigation.

May said his office expected to file formal charges within the next 10 days.

Frazee’s arrest warrant was sealed.

“We are not going to unseal records if it will put the investigation in peril,” May said. He added that it could take a couple of weeks before the affidavit, which lays out the evidence in the case, will be released.

Berreth was last seen alive on Nov. 22. That day, a security camera inside a Safeway grocery store recorded her shopping with her 1-year-old daughter, Kaylee, who is also Frazee’s daughter.

Frazee told law enforcement that he had met Berreth that afternoon, which was Thanksgiving, to pick up his daughter for a visit.

A court document available online indicated Berreth was killed on Thanksgiving Day.

Frazee’s mother reported her missing on Dec. 2.

The disappearance mystified her family and police because Berreth, a flight instructor, was known as a reliable person and a devoted mother. The multi-state search captured attention from the national media, which has had a non-stop presence in Woodland Park since her disappearance was reported.

“I’m stunned. I don’t know what to say,” Berreth’s cousin, Jodee Garretson, 50, of Pasco, Wash., said Friday after learning of Frazee’s arrest. “I’m very eager to find out where Kaylee is.”

Kaylee had been living with Frazee until his arrest, when she was placed in protective custody. She soon will be given to her mother’s family, De Young said.

During the search for Berreth, which involved Woodland Park police, the Colorado Bureau of Investigation and the FBI, police discovered her cell phone pinged a tower in Gooding, Idaho, on Nov. 25.

That day, her employer, Doss Aviation, received a text message from Berreth’s phone saying she would not be at work for the next week. Frazee also told police that a text from his fiancé that day had been the last he had heard from her.

“Her phone did end up in Idaho and we are still working to recover that phone,” De Young said.

The search for Berreth’s body continued Friday.

“This has been a methodical, time-consuming, multi-state operation with investigators working nearly around the clock to find Kelsey,” De Young said. “While we have not found Kelsey at this time, information has been developed to help us narrow down our search.”

FBI Assistant Agent-in-Charge Mike Nordwell said the agency’s Evidence Response Team, technicians, field agents from multiple states and Behavioral Analysis Unit experts worked on the case.

“You’ll be seeing a lot of law enforcement activity in our community in the coming days and even weeks as we continue our relentless pursuit for justice for Kelsey and her family,” De Young said.

On Dec. 14, authorities executed a search warrant on Frazee’s 35-acre ranch in Crystal Peaks Ranches subdivision near Florissant. The search lasted three days, but officials never reported what evidence may have been found.

Law enforcement had returned to Berreth’s home on Thursday for a second search, just a day before Frazee was arrested.
