A spokesman for a tourist boat that found a capsized speedboat Sunday between Florida and the Bahamas says it was a "horrific" scene.

In the water were several bodies, with tiger sharks circling. Rescuers say one body was devoured as they watched.

Police in Puerto Rico believe the victims were four Haitian migrants trying to make it to the U.S. It's thought their boat capsized in rough water.

Thousands of Haitians try to sail to the U.S. every year in rickety, overcrowded boats. Last month, at least 20 died on a trip from the Bahamas to Florida.
