Alonza Kent, 40, of Gulf Breeze, Florida, was last seen on August 26, 2011, after leaving for a solo fishing trip in the Gulf of Mexico aboard his 36-foot Boston Whaler, Monkey Bar II. He was expected back that day but never returned; family reported him missing on August 28 and a large search followed.

A few days later the boat was found drifting off the Yucatan Peninsula near Chuburna, Mexico. The vessel was empty, the keys still in the console, and there were no immediate signs of foul play aboard. The U.S. Coast Guard conducted an extensive search over an area larger than the state of Maryland but found no trace of Kent. His family held a memorial service and has accepted the likelihood he was lost at sea, though some reports raised unproven theories about piracy or illegal activity.

What information might help fill the remaining gaps in this disappearance?
