Berreth texted her employer, Doss Aviation, on Nov. 25 to say she would not be at work the following week, the Post reported. She also texted Frazee that day. He told police he had not seen Berreth since Thanksgiving, when they exchanged custody of their 1-year-old daughter, Woodland Park police Chief Miles De Young said.
According to investigators, Berreth's cellphone was pinged at 5:13 p.m. Nov. 25 near Gooding, Idaho, KDVR reported. According to a Facebook page set up to track the search, Berreth has family in Idaho and Washington.
Investigators have searched Berreth's home and work and have not identified anyone as a suspect, De Young told the Post. All of her belongings were still inside her home, except for her purse.
There was no indication Berreth had used a Doss Aviation aircraft or any record that she and her fiancé were having relationship issues, De Young told the newspaper.
Meanwhile, Berreth’s family continues to seek her whereabouts.
“Kelsey, we just want you home. Call us if you can. Someone knows where she’s at,” Cheryl Berreth said at Monday’s news conference.
