A 79 year old ex- CIA agent confessed to being the reason Bob Marley died from cancer. In an interview with Widley Online, Oxley said âI gave him a pair of Converse All Stars. Size 10. When he tried on the right shoe, he screamed out âOUUUCH.â That was it. His life was over right there and then. The nail in the shoe was tainted with cancer viruses and bacteria. If it pierced his skin, which it did, it was goodnight nurse," RIP Bob Marley
