Fraser Horne, 64, of Cortez, Florida, was last seen on November 17, 2017, when he left the Bradenton area on a boating trip with his dog but never returned. His boat was later found near Egmont Key still running, with the dog unharmed onboard. The U.S. Coast Guard and other agencies searched more than 2,100 square miles without finding Fraser.

Authorities believe he likely drowned; no evidence of foul play has been reported and the case remains unsolved. Is there anyone who saw Fraser or his boat on November 17, 2017, or who has information that could help explain what happened?
