ANCHORAGE, Alaska — A domestic dispute aboard a cruise ship led to the death of a 39-year-old Utah woman, and the FBI is investigating what happened in U.S. waters off Alaska, the agency said Wednesday. Princess Cruises said the woman died Tuesday night on the Emerald Princess, which was carrying 3,400 passengers and 1,100 crew members on a weeklong trip that left Sunday from Seattle. Company spokeswoman Negin Kamali declined to provide any other details about the case, including the woman’s name, and referred questions to the FBI. FBI spokeswoman Staci Feger-Pellessier said an agency team was headed to Alaska’s capital city of Juneau and no arrests had been made. The Emerald Princess was diverted to Juneau because of the investigation.
