The airman was discovered outside the Fort Walton Beach Medical Center, roughly seven miles from the base.
Staff Sgt. James Grotjan died at Landstuhl Regional Medical Center in Germany four days after his accident in the United Arab Emirates.
Hurlburt said the airman cannot be identified until 24 hours after his or her next of kin has been notified. The airman’s cause of death is under investigation, and the base would not say whether foul play is suspected.
Last month, another Hurlburt airman, Airman 1st Class Divine Clark, was found dead in his on-base quarters.
