Las Vegas police have arrested a man in the deadly 1996 drive-by shooting of Tupac Shakur, a long-awaited break in a case that has frustrated investigators and fascinated the public ever since the hip-hop icon was gunned down on the Las Vegas Strip 27 years ago. Duane “Keffe D” Davis was arrested early Friday morning, although the exact charge or charges were not immediately clear, according to two officials with first-hand knowledge of the arrest. They were not authorized to speak publicly ahead of an expected indictment later Friday.
