Anthony Karkoski, 38, was last seen in Port Austin, Michigan, on June 14, 1980. Public missing-person records link his disappearance to a boating accident and say he is presumed to have drowned in Saginaw Bay or Lake Huron, but they do not provide a detailed timeline or a clear offshore location.

Case listings describe Karkoski as White/Caucasian, about 5 feet 6 inches and 200 pounds, with black hair and blue eyes, and record him in NamUs as MP29526. There is no publicly documented recovery, no account of clothing or personal items, and no public description of witnesses, an abandoned boat, distress call, or the search that followed.

The circumstances reported point to an accidental drowning on the water rather than an intentional disappearance, yet the absence of specifics and an official resolution has left the case unresolved. If anyone knew Anthony or has information about boating activity off Port Austin on June 14, 1980, please come forward.
