Steven Kubacki
In February 1978, Steven Kubacki, a 23-year-old student at Hope College, disappeared without a trace in an area known as the Lake Michigan Triangle. The area stretches from Manitowoc, Wisconsin, to Ludington, Michigan, and south to Benton Harbor.
He went on a solo cross-country skiing expedition, but at one point, he vanished. However, the area where he went missing had been the scene of other mysterious disappearances before.
