By JESSICA HILL Associated PressLAS VEGAS (AP) — A Nevada judge ruled on Tuesday that the recording of an interview the man accused of killing Tupac Shakur gave to police in 2008 could be used at his upcoming trial. The interview was used in former Los Angeles Police Department Detective Greg Kading’s book “Murder Rap: The Untold Story of the Biggie Smalls & Tupac Shakur Murder Investigations.” None of the others faced charges in Shakur’s killing before they died. In the 2008 interview, Davis describes how he and his crew saw Shakur that night and pulled up beside them, and said that Anderson “popped them.” Anderson denied involvement in Shakur’s killing at the time, and died two years later in an unrelated gang shooting in Compton, California.
