Bob Marley died on May 11, 1981 at age 36; it's a proven fact. However, the circumstances leading up to his death are quite suspicious.
In early July 1977, Bob Marley injured his right toe during a game of football, or soccer. He was laid down and a doctor was called to tend to it. According to Wailers manager Don Taylor in his book Marley and Me, an unknown doctor arrived and gave an unknown injection into his toe and left. It was later that month when Marley was diagnosed with acral lentiginous melanoma, a malignant cancer, in the same toe.
There are many imaginable reasons why one would murder Marley; his religious views, his music, his activism; many Christians were somewhat offended when, in 1976, Marley claimed "God is black" in an interview with a journalist. In truth, the Rastafari movement was ignored and rejected by some. This would be somewhat of a motivation.
