An FBI investigation has been launched after the suspicious death of a woman on a cruise ship.
The crew was notified of a woman found unresponsive onboard, and medical personnel rushed to help.
Cruise ship Carnival Sunshine had departed from Charleston, South Carolina, US on February 27 heading to the Bahamas.
After failed attempts to resuscitate the woman, she was pronounced dead and her body was removed three days later when the ship arrived in Nassau.
When the ship later returned to Charleston on March 4, an FBI team of investigators boarded the cruise and examined the woman's room.
The woman had been travelling with her husband, a statement from the operator said.
The FBI told DailyMail.com in statement that it "investigates certain crimes on the high seas, as well as suspicious deaths of US persons".
It added that the "incident was isolated and there was no threat to any other passengers before or after the passenger was found deceased".
Carnival said it was also co-operating with local authorities.
A statement read: "The FBI joined Carnival Sunshine upon its return to Charleston yesterday morning to conduct an investigation into the death of a guest."
It added: "Both the deceased and her husband were debarked in Nassau and Bahamian authorities have already investigated the circumstances and are conducting an autopsy.
"We are fully cooperating. This is a matter for authorities in The Bahamas and Charleston and we have no further comments."
Carnival Sunshine's home port is in South Carolina.
It was floated in 1996 as Carnival Destiny, before being renamed in 2013.
In February, a dad tragically dropped dead in front of his horrified wife on a Hawaiian cruise.
John Thompson, 74, was visiting Honolulu on a luxury holiday with his wife when he fell ill during a meal and collapsed.
Emergency services were called and worked frantically on John, before he was rushed to hospital for further treatment, but medics were unable to revive him.
His grieving family has now been told they face medical bills in the region of £30,000 after issues were raised with his travel insurance.
John's son Dale Thompson, of Burnhope in County Durham, said: "On the day of travel my dad must have noticed there was not something not right with the insurance once they were through customs.
"It said they were covered until the 2nd and not the 22nd but why would they only need three days of cover.
"I spoke to my parents and said to just take it easy on holiday and not exert themselves so they wouldn't break a leg or sprain an ankle. Dad has always had health issues but nobody was expecting this to happen."
