A local man is believed to be dead after falling off a jet ski.
Rescue workers searched in the water and in the air, but found nothing.
It happened at Lake Osborne near Lake Worth.
The man was a passenger on a jet ski and was not wearing a life jacket.
We're told the jet ski flipped and he did not know how to swim.
"We see them going up and down the waterways here in South Florida every day...it's fun, it's a beautiful day today, but personal safety comes first," said Captain Andrew Bilardello of the Palm Beach Sheriff's Office.
