A former Southern California street gang leader pleaded not guilty Thursday to murder in the 1996 killing of rap music icon Tupac Shakur in Las Vegas - a charge prompted by his own descriptions in recent years about orchestrating the deadly drive-by shooting.ĭuane Keith 'Keffe D' Davis is the only person still alive who was in the vehicle from which shots were fired and the only person ever charged with a crime in the case.
