How was Tupac Shakur killed?

Nearly 30 years after Tupac Shakur was fatally shot on the Las Vegas Strip in Nevada, prosecutors have prepared for the trial of the only person ever charged in connection with the rapper’s death: Duane “Keffe D” Davis.

Davis has pleaded not guilty to murder and denies the allegations against him.

The BBC's Shaimaa Khalil explains the case as the suspect goes to trial.
