TIERRA VERDE, FL (AP) - Authorities are searching in southwest Florida for a swimmer who has been missing four days.
The Pinellas County Sheriff's Office used boats and helicopters to search the area near Fort De Soto Park where 29-year-old Kevin Persad was last seen Wednesday.
Witnesses said they tried to save him, but the currents were too strong.
Authorities said the effort has switched from a rescue to a recovery.
