Park rangers are on the lookout for Peter Louis Kastner, 25, from Oklahoma City, Okla. Rangers believe Kastner may have been in the area for up to two weeks, and may not have been using his own name in any contact with individuals or businesses. 

During a routine patrol early Monday morning, rangers found a 2010 Red Cadillac STS sedan with Oklahoma license plates parked at the Hellroaring Trailhead, 3.5 miles west of Tower Junction.

The vehicle, which had obviously been parked overnight, was not associated with an overnight backcountry permit.  A check showed Kastner had rented the vehicle several days earlier. Limited personal belongings were discovered in the car.

A preliminary search and questioning of hikers, backpackers, and area businesses have failed to turn up any information on Kastner’s whereabouts. Dog teams are being added to the search effort this afternoon.

Kastner is described as 6 foot 1 inch tall; 185 pounds, with brown hair and hazel eyes.

Anyone with information regarding Kastner is asked to call Yellowstone National Park at 307-344-7381.
