FLAGSTAFF, Ariz. (AP) — An autopsy shows that an inmate at a Coconino County jail likely died from peptic ulcer disease.
The county Medical Examiner's Office lists the manner of death for 63-year-old Floyd Jackson as natural.
Medical staff at the jail were examining Jackson in his cell Sunday morning when he became unresponsive.
Authorities say they began administering CPR and other lifesaving measures until paramedics arrived, but Jackson was pronounced dead 30 minutes later.
Jackson had been transferred to the Coconino County Detention Facility last Thursday from the downtown Phoenix jail.
When he was booked into the Flagstaff facility, jail staff say Jackson did not include ulcers among his medical conditions.
Jackson was being held on a $200 bond for an outstanding failure to comply warrant for driving with a suspended license.
