DEVELOPING: The Coast Guard is searching for a Texas man who fell from a Royal Caribbean cruise ship off the coast of Key Largo, Florida.

Coast Guard officials say 46-year-old David Mossman fell from the 10th deck of the Navigator of the Seas ship early Saturday, a distance of about 100 feet. His hometown wasn't immediately reported.

The Coast Guard says in a news release that a helicopter and plane are being used in the search over some 946 square nautical miles.
