Edward Konrad Ludwig, 27, was last seen leaving his job at Bow Valley Provincial Park in Canmore on May 30, 1986, intending to spend the day at Lake Minnewanka in Banff National Park. When he failed to return, a search was launched and his boat was found empty and adrift on the lake — the key, unsettling fact that triggered concern but has not led to a resolution.

At the time he disappeared he was described as a Caucasian male, 6 feet 3 inches, about 194 pounds, with brown hair and brown eyes. Reports note he had been feeling despondent before the trip, a detail the family has cited in accounts of the case.

Decades of investigation have not produced definitive answers and the case remains open. Does anyone who was on or near Lake Minnewanka on May 30, 1986, or who knew Edward then, have information that could help clarify what happened?
