The holographic version of Tupac exists, as Coachella demonstrated last weekend, but the rapper was shot and killed in 1996...or was he? Doubt has been cast on whether or not Tupac Shakur actually died in the attack in the past, but the man who drove the car in which Tupac was shot is now helping out with that conspiracy theory. Suge Knight, former CEO of Death Row Records, told a Los Angeles radio station last week that he wasn't sure Shakur really did die in the drive-by shooting in Las Vegas. "Maybe the question is ... Pac's not really dead ... pac's somewhere else," Knight told 93.5 KDay's morning show. When asked if he ever saw Tupac's body following the 1996 shooting, he adds, "Nobody seen Tupac dead." Except in hologram form at last week's Coachella concert, of course. Knight also spoke out about that "performance," which he said was missing one key accessory. TMZ reports Knight is "furious" over the omission of Shakur's ever-present Death Row chain. "At the end of the day, how you gonna take the Death Row chain off Pac? That's like taking the Raiders symbol off the Raiders."
