Kristy Manzanares, 39, was killed in her cabin Tuesday night aboard The Emerald Princess in what the FBI described as a domestic dispute.
Her husband, Kenneth, is in custody after his wife was discovered to have "a severe head wound and blood was spread throughout the room" says an FBI criminal complaint.
Her husband allegedly told a witness, "She would not stop laughing at me. My life is over."
Kenneth reportedly tried to jump overboard but was restrained by members of the ship's crew.
The Utah couple was celebrating 18 years of marriage and their three teenage daughters were with them on the vessel.
