Three men are facing charges after the murder of an off-duty state trooper in Jefferson County Friday morning. 24-year-old Treyon Washington turned himself in today after 17-year-old Cdarrius Norman and 25-year-old Damion Whittley were arrested in New Orleans. All three are charged with murder in the death of Lt. Troy Morris who was shot in his postal transport truck after having a flat tire on Highway 61. Morris worked part-time for the Postal Service as an independent contractor.
