The two men who died when an airboat capsized in the St. Johns River late Sunday have been identified.

Motilail Persaud, 71, and 84-year-old Richard Rocco were on the airboat when it flipped over.

Two other people managed to get to shore, including the airboat operator.

Florida Fish and Wildlife Conservation Commission investigators are trying to piece together what happened as witnesses said the boat was going really fast before it capsized.
