An autopsy has revealed that a 42-year old Bandon male, who died while incarcerated in the Coos Co. Jail Sunday, Dec. 3, died of natural causes.  Rocky Alan Stewart had been suffering from “severe coronary artery disease,” according to a news release from District Attorney R. Paul Frasier.  “There is no evidence of any foul play in Mr. Stewart’s death.” Stewart was arrested Saturday evening on a charge of Assault IV stemming from a Domestic Disturbance at a residence south of Bandon.
