Mark Graeme Krostewitz was 23 when he left Winnipeg for a trip to Europe on June 7, 1989, and did not contact family afterward. He is 5 feet 9 inches, about 157 pounds, with red hair, blue eyes and pronounced eyelids, and he lived with epilepsy, a fact his family considers important to the case.

His family reported him missing in October 1989 after months with no word. A puzzling lead came in January 1990 when a female hospital employee in London, England, called the family asking about relatives of someone named Graeme Mark or Gary Markham; the family now believes that call may have referred to Mark, possibly after a seizure that left him unable to identify himself. In February 2000 a male body found in Wales was forensically excluded as Mark.

The disappearance remains unsolved and the investigation is open. If anyone knew Mark’s travel plans, contacts in Europe, or saw a young red-haired man matching his description after June 7, 1989, please report what was observed.
