The Colorado Bureau of Investigation is working to identify human remains found at a truck stop about a two hour drive from Woodland Park, where missing mother Kelsey Berreth was last seen on Thanksgiving Day.

KKTV reports that human remains were found on Sunday at an abandoned truck stop near the town of Aguilar. The remains have not yet been identified pending a medical examination, and there is no word on the possible cause of death.

Authorities are expected to release more information on Tuesday afternoon.

There is no indication at this time that investigators suspect the remains belong to Kelsey Berreth, who is presumed dead but whose body has not been found. Very little is known at this time about the discovery of the remains.

Patrick Frazee, the father of Berreth’s 1-year-old daugher, was arrested and charged with multiple felony counts in Berreth’s presumed death, including first-degree murder and three counts of solicitation of first-degree murder. Authorities said in a press conference announcing his arrest last month that additional arrests were a strong possibility, but no additional suspects have been named.

This is a developing story. CrimeOnline will provide further updates when more information is available.
