There have been many conspiracy theories about Tupac's death over the years. Consequences of Sound blogged some of the many unanswered questions about his death 20 years later—while claiming Pac is still alive and living in Cuba.
"The unsolved mysteries surrounding Tupac’s death have led conspiracy theorists to surmise that the rapper is still alive. For example, they argue, of the 14 shots fired, why did only a fragment of one bullet hit the driver, Suge Knight? Why was Tupac not wearing a bullet proof vest (even though he was known to do so on other public outings)? On a normally busy Saturday night in downtown Las Vegas, not one person saw the shooter? Why was the autopsy photo fake? Why did the coroner list Tupac as 6 feet, 215 pounds when in reality he was 5’10 and 168 pounds?"
