Cadaver dogs have joined the search for a man missing in Natrona County since last week, but a sheriff's office spokesperson declined to say whether authorities suspect the missing man is dead.

One cadaver dog is being utilized as of Thursday morning, with two more expected to join in the search.

John Barnhill was reported missing last Tuesday. Authorities found his vehicle in the area of Sheepherder's Hill on Saturday.

Natrona County Sheriff's Office Investigative Sergeant Sean Ellis said deputies do not suspect foul play in Barnhill's disappearance.

Anyone with information regarding Barnhill's whereabouts is asked to contact the Natrona County Sheriff's Office at 307-235-9282.
