Prosecutors contend he directed the attack and supplied the gun used in the drive-by shooting that killed Mr Shakur. Mr Davis, 63, could spend the rest of his life in prison without parole if convicted. Mr Shakur died at 25, at a moment when hip-hop was defined by an escalating rivalry between East Coast and West Coast artists and labels. Later that night, prosecutors say, a white Cadillac carrying Mr Davis, Mr Anderson and others drove alongside Mr Shakur’s vehicle in Las Vegas. Mr Davis now says he was in Los Angeles on the night Mr Shakur was shot.
