MARATHON, Fla. – The search continues for a man who fell from the Liberty of the Seas cruise ship about 20 miles off the coast of the Florida Keys.

The U.S. Coast Guard says they don’t know whether the man jumped or fell from the ship on Sunday night. Royal Caribbean Cruises said in a statement that a review of the ship’s closed-circuit camera footage shows the man climbed over the railing of deck 12 and jumped.

The ship docked at Port Everglades in Fort Lauderdale Monday after a four-night cruise that stopped in Cozumel, Mexico, on Saturday.

Coast Guard crews searched with a helicopter and a cutter on Monday.
