Evidence in Case of Missing Colo. Mom Found in Idaho

A missing Colorado mom's phone pinged a cellphone tower near Gooding, Idaho, three days after her last confirmed sighting. Now, police in the latter state say they have gathered evidence in relation to Kelsey Berreth's disappearance. KRDO reports authorities in Twin Falls, Idaho, didn't elaborate beyond saying they've served "several" search warrants and processed "some items of evidence." A press release adds they were contacted by the FBI on Dec. 15 and asked to participate in the investigation. The Denver Post reports Gooding is about 35 miles from Twin Falls.

The development came one day after Berreth's fiance, Patrick Frazee, was arrested in connection with her death. The AP reports his next court date is Dec. 31. Though police have not found a body, they do not believe Berreth is alive and say evidence suggests a crime occurred in her home, which she and Frazee did not share. They have a 1-year-old daughter. The AP adds that Berreth's mother had previously described the couple as having a solid relationship and said the delay in moving in together had financial roots: Frazee runs a cattle ranch, and industry prices are down, which she says forced them to put their plans on hold. (Cops allege Frazee may have had help in killing Berreth.)
