Just before she died in May, Tupac Shakur's mother Afeni reached out to her family friend, noted civil rights attorney Benjamin Crump, with a desperate plea: find out, once and for all, who killed her son. In this 6 episode investigative series, Crump will treat the Tupac case exactly as he has treated other high-profile murder cases: he will interview the witnesses (some who have never talked before), review the evidence, examine the many theories, and come to the most informed and definitive conclusion as to what happened and why. In each episode, Crump and journalist Stephanie Frederic (who has covered Tupac's case since his murder), will examine one of the key theories. They have secured the last remaining eyewitness to his murder. And they will restage the crime scene in Las Vegas to shed new light on the case.
