**FILE**Rap musician Tupac Shakur is shown in this 1993 photo. Another rapper, Proof, was shot in the head Tuesday, April 11, 2006, on the same Eight Mile Road in Detroit that he and Eminem made famous in movies and songs. He joins a long list of rap stars including Shakur, the patron saint of slain rappers, who was famously doomed by his fascination with the "thug life."
