Donald Gene Kerl, 61, was last seen in Riverton, Wyoming on July 18, 2014. At that time he was living a transient lifestyle out of his vehicle; his pickup was described as a white 1992 GMC or Chevrolet with Montana license plates. He had known ties to Kansas and Montana.

Several months after he was last seen, in October 2014, Kerl’s pickup was found abandoned in the Wind River Casino parking lot, but there was no sign of him at the scene. Few details about the investigation have been released; the Fremont County Sheriff’s Office lists the case as an active, unsolved missing person investigation.

Kerl is described as a white male with gray hair and blue eyes, 5 feet 10 inches tall and about 220 pounds. Anyone who may have seen Kerl, his truck, or has information about his whereabouts is asked to contact the Fremont County Sheriff’s Office.
