Authorities said the county medical examiner’s office will try to determine the cause of death.
Sheriff’s deputies responded Saturday to the Antelope Hills area of Flagstaff along Highway 89 about a trespass in progress, but the person had already left the area.
Deputies were able to identify Stults after his vehicle was found at the scene and a search for him began.
It was still unclear Wednesday why Stults was in northern Arizona.
