William Cameron Brown, 66, was last seen October 5, 2010, at Geiger Key Marina in Monroe County, Florida. He lived on a boat near the marina with his dog and routinely used a small homemade fiberglass dinghy to go between his boat and shore. That day he reportedly left the dog on the boat and was heading to the Key West courthouse to pay fines but never arrived.

Authorities later determined both Brown and his dinghy were missing. An extensive search, including examination of local waters, turned up no trace of him or the dinghy. His case is classified as lost/injured missing; he was described at the time as having gray hair, brown eyes, a gray beard, eyeglasses and a tattoo of an ant on his navel.

No definitive clues about what happened have emerged. Does anyone who knew Brown, saw him near Geiger Key on October 5, 2010, or has information about a small homemade fiberglass dinghy, please contact the Monroe County Sheriff’s Office?
