The family of an 18-year-old high school senior who died under mysterious circumstances on a cruise ship in the Caribbean is breaking their silence. Anna Kepner's grieving father, Christopher, says he is desperate for answers. Anna died on the Carnival ship "Horizon" at 11:17 a.m. according to the Miami-Dade medical examiner. Instead of flowers for the funeral, friends were encouraged to leave flowers on Anna's car, which is parked at her high school outside Orlando where she last left it. #Carn
