Kentucky’s corpse found in the Grand Canyon is believed to have gone missing.

The National Park Service recovered an autopsy in the Grand Canyon believed to be a missing Kentucky man.

Along with the autopsy, park personnel found a motorcycle under the South Kaib Trail on Wednesday.

Authorities believe the man is 40-year-old John Pennington, who was reported missing last week.

Pennington was last seen on the South Rim of the Grand Canyon, presumably riding a yellow motorcycle, NPS has said.

The National Park Service and the Cocono County Medical Examiner are investigating the death.
