The FBI has arrested a suspect in the cruise ship death of a 39-year-old Utah woman.

Time reports the suspect was taken into custody late Wednesday and is expected to be charged today in what federal authorities are calling a domestic dispute that led to the Tuesday night death of a woman aboard the Emerald Princess in U.S. waters off Alaska. 

At the time, the ship was carrying 3,400 passengers and 1,100 crew members during a weeklong trip that departed Seattle on Sunday.

Details of the death remain a mystery.

The FBI gets involved in deaths that occur in international or U.S. waters.
