Authorities discovered the body of Adam Chase Harris, 26, of Oxford, Tuesday near Adam's Gap Trailhead in the Talladega National Forest, said Clay County Deputy Coroner David Holcombe.

Family members had reported Harris missing late last week, sparking an investigation. His body was being taken Tuesday to a forensics laboratory in Montgomery for an autopsy. Holcombe declined to provide the cause of death pending the results.

On Monday, a state game warden spotted an abandoned vehicle near the trailhead, Holcombe said. Holcombe would not say if the car found was Harris' green 1997 toyota Corolla. A 10-person search crew from the Clay County Rescue Squad and a state game warden searched overnight. They found the body at approximately 7:30 a.m. Tuesday, Holcombe said.

No one had heard from Harris since Thursday when he reportedly called relatives to say he'd run out of gas on Kentuck Road. His wife, Diana, went to look for him after he failed to arrive home that night, but she never spotted his car.

Kentuck Road is near Talladega County, which led authorities to begin a multi-agency search in Clay and Talladega counties.

The Talladega County Sheriff's Office, the Alabama Department of Wildlife and Fisheries and Oxford police began running down leads, but found nothing said Sgt. L.G. Owens, an Oxford police investigator.

"He was reported missing in our city and leads that we had run down didn't turn up anything," Owens said.

The Clay County Sheriff's Office took over the investigation following the discovery. Attempts to reach officials at that office Tuesday were unsuccessful.
