William Mark Adair, a 29-year-old alarm technician from Bonita Springs, Florida, was last seen August 31, 2008, after going boating off Key West. At about 2:30 p.m. he texted a family friend that he was returning to shore but never arrived. His truck and boat trailer were later found abandoned at the marina of John Pennekamp Coral Reef State Park in Key Largo, which had been evacuated that day as Hurricane Ike passed nearby.

Two weeks later his 17-foot single-engine Sailfish was found overturned in a commercial fishing area more than 60 miles west of Key Largo and ten miles south of Pine Key. The capsized boat appeared in good condition, and investigators surmised it had overturned in the hurricane-forced seas; there was no sign of Adair and a U.S. Coast Guard search was later suspended. In the week before he vanished his wife told him she was filing for divorce and he took three days off work; he was due back September 1 and was reported missing by coworkers on September 2. The case remains unsolved; his fate is unknown.

Did anyone who knew William or who was boating in the western Keys around August 31, 2008, see his boat or have information about his movements that day?
