A 19 year-old Ohio inmate was found dead at the Stark Regional Community Corrections center on Saturday, according to newly released reports. Officials cannot figure out how the inmate died, but an extensive investigation is underway.

Marcus Anthony McElroy was found deceased in his bed, and a preliminary autopsy revealed no sign of trauma or injury. The Stark County Coroner is conducting further autopsy and toxicology reports, although they will take a minimum of four weeks to complete.

McElroy had been at the facility for seven weeks, after being found guilty of marijuana. He also had previous charges of cocaine possession. Officials do not believe there was foul play related to McElroy's death, and their investigation continues.
