New details have emerged in the murder of a 39-year-old mom on a cruise ship during a domestic dispute. Kenneth Manzanares wept as he was arraigned in federal court for the murder of his wife Kristy. The couple was on a cruise to Alaska with their three teenage daughters. Passenger Charles Rowlen said he heard loud screams from the family's state room two decks below his at the time of the murder. Rowlen said Kristy looked over the balcony and saw Kenneth Manzanares trying to jump overboard. #InsideEdition
