A former Compton gang detective testifies that Duane “Keffe D” Davis was a high-ranking “shot caller” in the South Side Compton Crips. Prosecutors allege Davis orchestrated Tupac Shakur's shooting nearly 30 years ago in retaliation for a casino brawl involving Davis’ nephew. They have not accused Davis of firing the shots but claim he provided the gun. Davis has admitted in past interviews to being in the car during the shooting. Defense attorney Michael Sanft emphasizes the lack of physical evidence. Prosecutors argue Davis’ own words are central to their case.
