The Boulder County Coroner's Office has identified the man found dead after an apparent one-car accident on Peak to Peak Highway west of Boulder as Joseph Hibdon, 39, of Longmont.

The Colorado State Patrol said a witness spotted a car at about 1 p.m. Sunday that had run down an embankment on Colo. 72.

Hibdon was found dead at the scene. No other people or cars appear to have been involved in the accident, and investigators do not know yet when or how the accident occurred.

Boulder County Coroner Emma Hall will conduct an investigation to determine a cause and manner of death.
