According to Carnival Cruise Line, the passenger who died aboard a Carnival Cruise Line ship over the weekend likely died naturally.

According to CBS News and NBC, the cruise line said Tuesday that “all indications indicate that the woman died of a medical condition while aboard the Carnival Sunshine in the Bahamas.”

The Federal Bureau of Investigation (FBI), previously called the February 27 death “suspicious.”

Carnival said on Tuesday that “it appears that this was indeed an unfortunate medical situation which unfortunately resulted in the death of one guest,” according to reports.
