Prosecutors allege Davis orchestrated the retaliatory hit as the 'shot caller,' relying on the defendant's own public admissions to secure an indictment.

Decades after the 1996 shooting in Las Vegas, former gang leader Duane Davis stands trial as the sole remaining suspect in the murder of Tupac Shakur.

Prosecutors argue the former gang leader acted as the shot caller who coordinated the plot and provided the weapon for the fatal drive-by shooting.
