The U.S. Coast Guard says it has suspended its search for a 42-year-old man last seen falling from the Carnival Conquest cruise ship.

The search began Saturday when a passenger reported seeing a person go overboard. The Coast Guard described the man as an Asian-American. No other details have been released.

The Carnival Conquest was finishing a seven-day Caribbean trip out of Galveston when the man was reported missing.

The Coast Guard says it searched 520 square miles with helicopters, boats and jets.
