Guma Leandro Aguiar, 35, was last seen at sunset on June 19, 2012, leaving his private dock in Fort Lauderdale on his 30-foot Jupiter center-console boat, the T.T. Zion. Home surveillance shows him alone; a neighbor reported the boat speeding through the canals. Conditions that evening were poor: thunderstorms, 20-mile-per-hour winds, and four to five-foot swells.

About six hours later the unoccupied boat washed ashore on Fort Lauderdale Beach near the Elbo Room with navigation lights on, keys in the ignition, throttles forward but engines off, and items including his wallet, cell phone, and some clothing aboard. GPS and engine data indicate the boat ran north along the coast about four miles offshore, showed erratic speed changes, then experienced steering problems when a tie rod between the twin outboards broke and both engines stopped at 7:54 p.m. The Coast Guard searched an area the size of Rhode Island for two days and found no trace of Aguiar. In January 2015 he was declared legally dead at his family’s request, with a presumption of accidental drowning; his body has never been recovered.

Did anyone on the water that night see a small center-console vessel behaving erratically or a person in the water?
