On Dec. 15, the Twin Falls Police Department worked with the FBI and Colorado Bureau of Investigations to serve several search warrants and process evidence as part of the ongoing investigation into Kelsey Berreth's disappearance.
Twin Falls Police released the statement Friday afternoon.
"We are pleased our organizations were able to provide the assistance and support requested by the FBI, CBI, and the Woodland Park Police Department," said Sheriff Tom Carter and Chief Craig Kingsbury in a joint statement.
Berreth's fiance was arrested yesterday on charges of murder and solicitation for murder.
Her phone was "pinged" near Gooding, Idaho, north of Twin Falls.
Barrett has been missing since Thanksgiving Day and was last seen in Woodland Park, Colo.
