(Dubois, Wyo.) – Fremont County Chief Deputy Coroner Mark Stratmoen said an investigation is continuing into a single vehicle crash near Lava Mountain Lodge west of Dubois on Tuesday at 10:31 a.m. in which a Dubois area man died. Fifty-One year-old Mark John Hyska’s car ran off of Highway 26/287 and through a fence. Stratmoen said a autopsy would be conducted on Thursday to help determine his cause of death.

The Chief Deputy Coroner said it’s possible that Hyska suffered a medical-related event prior to the crash, “but the autopsy would determine that. At this point, there is no known cause of death.”
