Authorities are investigating the death of a passenger aboard the Carnival Fantasy who fell from an upper deck to a lower deck while the cruise ship was docked in the Bahamas. The 26-year-old victim, whose identity was not released, fell from one of the upper levels of the ship's atrium to the lobby level late Friday night, Carnival Cruise Lines said in a statement Saturday. The ship was docked in Nassau at the time. Bahamas police said the man was from South Carolina and that initial reports indicate he may have jumped. He was pronounced dead at the scene. The ship was cleared by authorities to sail Saturday morning, but because of the delay due to the investigation a scheduled visit to Freeport was canceled. Carnival Fantasy was sailing on a five-day Bahamas cruise that departed Charleston, S.C., on Wednesday and is scheduled to return to Charleston on Monday.
