BOSTON, Dec. 22, 2005 – A grand jury today returned indictments charging two Boston men with first-degree murder and armed robbery in the August slaying of a cab driver in Brighton, Suffolk District Attorney Daniel F. Conley said.The indictments move the case against JASHAWN ROBINSON, 21 (D.O.B. 4/17/84), of Brighton, and CLEVELAND MARTIN, 19 (D.O.B. 7/4/86), of Dorchester, to Suffolk Superior Court, where it will be adjudicated. Robinson and Martin are accused of robbing and fatally stabbing 31-year-old Heureur Previlon early on the morning of Aug. 25. Previlon was found dead later that morning inside his cab in a parking lot near St. Elizabeth’s Hospital. After the murder, both men fled Boston to Virginia, where they were captured separately in September. Martin was arrested in the town of Suffolk, Robinson, in Chesapeake, Va. The arrests were the result of a comprehensive investigation by the homicide units of the Boston Police Department and Suffolk District Attorney’s Office that led to significant evidence pointing to Martin and Robinson. The defendants were returned to Boston in October and have been held without bail since their district court arraignments in the Brighton Division of the Boston Municipal Court Department. New arraignments on the indictment are being scheduled for early 2006 in Superior Court.
