FBI to investigate missing cruise passenger

The FBI says it will investigate what caused a 21-year-old Tennessee woman to fall off a cruise ship into the Atlantic Ocean off Florida.

The agency's San Juan, Puerto Rico, division said Tuesday that it would look into the case. Royal Caribbean says the Allure of the Seas was headed to Nassau, the Bahamas, when "a guest witnessed another guest going overboard" Sunday night. A surveillance camera also caught the woman's fall.

Two other nearby cruise ships initially joined the search for the woman. The U.S. Coast Guard says the woman is from Bartlett, Tenn. Coast Guard crews were searching Tuesday by air and sea. The Allure of the Seas skipped its stop in Nassau because of the search. It is due Wednesday in Philipsburg, St. Maarten.
