The Surry County Sheriff's Office said in a news release that jailers found 30-year-old Michael Adrian Martin in his cell Sept. 28.
The sheriff's office said Wake Forest Baptist Medical Center in Winston-Salem said Wednesday that Martin had died from his injuries.
Sheriff Jimmy Combs and District Attorney C. Ricky Bowman say they are awaiting a report by the State Bureau of Investigation.
There was no immediate word on why Martin was in the jail in Dobson.
