More details are emerging about an Idaho woman who is reportedly being investigated in connection to a possible role in the disappearance of Kelsey Berreth, a Colorado pilot and mother who has been missing since Thanksgiving.

As CrimeOnline previously reported, multiple sources have said that the woman, reportedly a 32-year-old nurse, is being investigated for possibly disposing of Berreth’s cell phone in Idaho. Law enforcement officials have not identified the woman because she has not been charged with a crime. Patrick Frazee, the father of Berreth’s one-year-old daughter, was arrested in late December and is facing multiple charges, including first-degree murder and three separate counts of solicitation of first-degree murder.

According to a Good Morning America segment, the woman has known Frazee for “years,” and previously worked with him in Colorado. The nature of their co-working relationship was not specified. Frazee is a cattle rancher and a farrier, a type of animal caretaker that tends to equestrian hooves.

A Daily Mail report cited two sources who claimed that Frazee and the woman had been involved in a relationship for several months and possibly dating back to 2016, before Frazee’s daughter with Berreth was born.

And a friend of Frazee’s had previously told CNN that Frazee and Berreth broke up on New Year’s Day in 2018. That woman, Tamra Freeman, also claimed that Frazee and Berreth had little contact outside of sharing custody of their daughter, and that he was the primary caregiver.

Three days after she went missing, Berreth’s cell phone pinged outside of Gooding, Idaho, which is about 40 miles from Twin Falls, where investigators have said evidence has been found, and where the woman connected to the investigation reportedly lives and works.

CrimeOnline will provide further updates when more information is available.
