Boxer Mike Tyson and rapper Tupac Shakur had more in common than you would think. Both men rose from poverty to become superstars. Both men were criticized for the violent and "thuggish" nature of their careers. Both men were sentenced to prison terms for crimes of a sexual nature. And perhaps most importantly, both men were good friends.

There's an additional link between them as well. Tyson and Tupac were together on the night of Sept. 7, 1996. This was the evening of Tyson's fight for a heavyweight boxing title -- it was also the night that Tupac was shot multiple times, leading to his death six days later. Shakur's brutal murder has never been solved.
