Davie, FL (CNN) - After scouring more than 1,500 square miles of rolling waves rescue crews have found no sign of a millionaire reported missing Tuesday.
Guma Aguiar's yacht washed up on shore in Fort Lauderdale Beach, Florida Wednesday, but he wasn't on board.
His mother is holding out hope he'll be found.
"We still hope that someone found him. We hope that, by some miracle, that Guma is still alive. The other option is that, because of the problems with his boat and the tumultuous sea, that he was tossed from the boat," said his mother, Ellen Aguiar.
The Coast Guard says it has suspended it search.
It says it is still investigating, though.
