FBI investigating "suspicious" death of a woman on a Carnival cruise ship

The FBI is investigating the "suspicious" death of a woman aboard a Carnival cruise ship traveling from Charleston, South Carolina, to Nassau, Bahamas, last month.

On Feb. 27, Carnival's Sunshine crew members and medical staff responded to an unresponsive female passenger, the FBI Columbia field office said in a news release. Despite their best efforts, the woman was pronounced dead on the ship, the release said. 

The incident was isolated and posed no threats to other passengers, according to the FBI.
