New documents have been publicly released in the legal proceedings against Kelsey Berreth’s fiancé.

Patrick Frazee was taken into custody Friday morning and faces charges for first-degree murder and solicitation of first-degree murder. His fiancé, Kelsey Berreth, hasn’t been seen since Thanksgiving, when a surveillance camera caught her walking through a Safeway store in Woodland Park.

Though her body has not yet been recovered, investigators believe that she is no longer alive and that she was killed in her Woodland Park home.

Monday’s court documents include a request from Frazee’s public defenders asking that investigators turn over emails and text messages they’ve recovered.

The defense and prosecution have also jockeyed over pre-trial publicity, with the defense alleging that “massive pre-indictment and pre-trial negative publicity” would impact Frazee’s right to a fair trial – something the prosecution denied in an opposing court filing.

These documents come two days after Twin Falls, Idaho police announced that they are assisting the FBI, Colorado Bureau of Investigation and Woodland Park Police Department to prepare and serve several search warrants.

Berreth’s phone pinged in Gooding, Idaho – less than area hour away from Twin Falls – on Nov. 25.

That same day, investigators say Berreth’s employer received a text from that number saying she wouldn’t be at work that next week.

Frazee was the last person to see Berreth alive. Woodland Park Police Chief Miles De Young said the two had exchanged custody of their 1-year-old daughter on Thanksgiving.

That child has since been placed in protective custody. According to a court docket, Berreth had a temporary custody hearing scheduled for Dec. 27.

Frazee does not have a prior criminal history in Colorado, according to CBI records. He is slated to appear in court again on Dec. 31.

De Young said it is an “absolute possibility” there could be more arrests in Berreth’s disappearance.
