Frank Langan, 53, of Jupiter, Florida, was reported missing on June 17, 2005, after a dive a few miles off the coast of Jupiter. A retired NYPD emergency service unit member and an experienced diver, Langan vanished during the dive and was not located despite extensive searches by the U.S. Coast Guard and local authorities. The circumstances of his disappearance remain unclear and the case is still open, though active searching has long been suspended.

Colleagues and the diving community noted the tragedy was especially striking given Langan’s training and history of challenging dives, and urged attention to diving safety and the buddy system. Does anyone have information about that June 2005 dive or remember seeing Frank that day?
