Tupac Shakur made a name for himself as an acclaimed rapper whose music fought against injustice towards African Americans. Tupac made hit after hit, creating four platinum albums over the course of his career.
But on September 7, 1996, he was seen leaving the MGM Grand Hotel in Las Vegas after getting into a fight. Shakur was in the passenger seat of a car when another car pulled up beside him at a red light, and 13 shots were fired. He died at the hospital on September 13.
Some believed his biggest rival, rapper Christopher Wallace (aka Biggie, Biggie Smalls, or the Notorious B.I.G.) was behind the murder, but he denied any involvement. On March 9, 1997, Biggie was also killed while waiting at a red light.
Since Shakur's death, seven albums have been released under his name, making him one of the best-selling artists of all time.
Over the years, there have been many theories about what happened to the men, Business Insider previously reported.
