Dietmar Johann Munhofen, a 58-year-old German tourist, was last seen June 6, 2013, while traveling in Montana. He had arrived in the United States on May 24, 2013, and was reported last in Great Falls. Munhofen’s vehicle was found nearly a month later, on July 5, abandoned in the Missouri River Breaks, a remote area of Fergus County northeast of Lewistown.

Munhofen was an avid photographer with an interest in Native American culture and lived with a medical condition that required a pacemaker, a fact that heightened concern after he disappeared. Despite extensive searches in the area, no trace of him has been found and investigators say there have been no significant leads.

Anyone who knew Munhofen, saw him in Montana in late May or early June 2013, or has information about his vehicle or movements in the Missouri River Breaks is asked to contact the Fergus County Sheriff’s Office.
