The FBI is investigating the «suspicious death» of a woman who was on a 5-day cruise from South Carolina to the Bahamas, the agency’s local office in Columbia Announced.

The death of the 44-year-old woman, whose name was not identified in the FBI announcement, occurred during a trip to Nassau, the capital of the Bahamas, the agency reported Sunday.

The cruise departed from Charleston on February 27, according to Matt Lupoli, Carnival Cruise Line’s senior manager of public relations. The passenger’s death likely occurred in the early morning hours of February 28, said Kevin Wheeler, a public affairs specialist with the FBI’s Columbia field office.

Medical personnel and crew members attempted life-saving measures once they learned the passenger was unresponsive, according to the FBI statement.

The woman had been traveling with her husband, Lupoli said. Her husband disembarked from the cruise ship in Nassau on March 1 and his remains were also disembarked from the ship, she said.

Investigators with the FBI Evidence Response Team processed the passenger’s room as evidence once the ship returned to Charleston as scheduled on March 4, according to the agency.

The FBI said the death was an isolated incident and that other passengers did not face any threats before or after the woman was found dead.

No one is in custody at this time, according to Wheeler. She said she could not comment on the circumstances of the woman’s death or any information about her husband or the status of the autopsy.

In a statement provided to NBC News, Lupoli said Bahamian authorities «have already investigated the circumstances and are conducting an autopsy» and that Carnival is «fully cooperating.»

«This is a matter for the Bahamas and Charleston authorities and we have no further comment,» Lupoli said.

Spokesmen for the Royal Bahamas Police Force could not immediately be reached.
