Millionaire Missing From Florida Yacht Guma Aguiar's empty yacht runs aground in Fort Lauderdale By Mary Papenfuss, Newser User Posted Jun 22, 2012 2:05 AM CDT 5 comments Comments Authorities are searching for troubled Fort Lauderdale millionaire Guma Aguiar after his boat was found aground on the beach Wednesday morning with its engine running. (JewsOnTelevision) (Newser) – A Florida millionaire's yacht came ashore this week—without the millionaire. Fort Lauderdale police are hunting for Brazilian-born Guma Aguiar after his empty yacht beached with the ignition running and lights on. The Coast Guard suspended its search yesterday after 70 hours hunting for the missing man in vain, and Aguiar's mother filed a motion in court to take control of his $100 million fortune, reports the Sun Sentinel. Ellen Aguiar's petition says her son "disappeared as the result of mental derangement" or disappeared "under circumstances indicating that he may have died, either naturally, accidentally or at the hands of another." It also states that he suffers from "severe bipolar disorder." Investigators believe Aguiar, 35, got into the yacht alone, "but that's not to say he didn't meet up with anyone," said a police spokesman. Aguiar made his fortune eight years ago when he and his uncle sold their energy company for $2.5 billion. Aguiar has been in an acrimonious legal battle over the money since. He has also been arrested several times, including for drug possession, driving under the influence, and domestic violence, reports ABC News.
