In October of 2017, a hiker found human remains in unincorporated Boulder County. The remains were found at Mud Lake Open Space, including a mandible and a skull.

More than a year later, the remains have yet to be identified. Cause of death also seems to remain unknown.

In attempt to help figure out who the bones are from, a facial reconstruction was completed, according to a press release from the Boulder County Sheriff’s Office.

In addition to the images related to the facial reconstruction, it has also been said that the deceased was “most likely male, of mixed ancestry closely associated with derived European ancestry and age is broadly estimated to be 30-60 years.”

Anyone who may have information regarding the case or anyone that recognizes the facial reconstruction is encouraged to contact Laurissa Lampi, the lead investigator. She can be reached at the Boulder County Coroner’s Office at 303-441-3535 or via email at
