Matthew Milton, 32, a scuba diver from Winter Springs, Florida, disappeared on November 2, 2014, after a dive off Islamorada in the Florida Keys. He and his brother-in-law, Jeff Stewart, surfaced to find their 23-foot boat had drifted away. Both tried to swim back but became separated; Stewart reached a mooring buoy and was rescued by the U.S. Coast Guard. An extensive search using Coast Guard helicopters, airplanes and boats covered thousands of square miles but turned up no trace, and the search was suspended after several days. Milton’s family and community were left devastated.

If anyone was in the Islamorada area that day or has information about Milton’s disappearance, please share what you know.
