Summary based on the NamUs case record (MP42151) and 2 other sources
Guy Carleton Schwark III, also known as Tony, was last seen on December 6, 1986, along with his friend Dennis Bagnall. The two men, both from Battle Creek, Michigan, flew from Fort Lauderdale, Florida, to Freeport in the Bahamas to pick up a boat for a friend of Dennis. They departed the Running Mon Marina around 11:30 AM, expecting to return to Fort Lauderdale by 6:00 PM. However, they never arrived, and neither the men nor the boat were ever seen again.

At the time of his disappearance, Schwark was 29 years old, standing 6'3" tall, weighing around 250 pounds, with reddish-auburn hair and green eyes. Foul play is suspected in their disappearance, but no conclusive evidence or leads have surfaced. Despite years of searching, the case remains unsolved, and Schwark's whereabouts are still unknown.
Last Seen: Dec 6, 1986
