A twin-engine plane crashed off the southern part of the state, killing three adults and a child.
The plane left Tamiami Airport, bound for the Bahamas, officials said. It was reported missing three hours later.
The Coast Guard found the bodies and the wreckage of the plane eight miles east of Miami.
Killed were Al Gustinger, who was in his 70s; Erik Gustinger and Idel Gustinger, both in their 30s; and Erik Gustinger Jr., 7, the Coast Guard said. All four were Americans, officials said.
The cause of the crash is under investigation.
