Allen Thompson, a 38-year-old lobster fisherman from Stonington, Maine, was last seen on October 11, 1989. He left the Stonington co-op that morning for what was described as a routine day of lobster fishing. Later the same day his boat was found abandoned and observed circling off the coast with no sign of Thompson aboard.

Extensive searches turned up no further clues to his whereabouts. At the time he disappeared he was described as 5 feet 10 inches, about 170 pounds, with brown hair.

Anyone who knew Allen, remembers seeing his boat that day, or has information that could help investigators is asked to come forward.
