The Tupac and Notorious B.I.G. fued is still going on even though both of the two main players are deceased. The LA Times has publised a story linking the Badboy camp with Tupacs death, but specifically the shooting at the Quad Recording Studio. I have read it and have my own theories... but check out a few exerpts:
"....Now, newly discovered information, including interviews with people who were at the studio that night, lends credence to Shakur's insistence that associates of rap impresario Sean "Diddy" Combs were behind the assault. Their alleged motives: to punish Shakur for disrespecting them and rejecting their business overtures and, not incidentally, to curry favor with Combs.
"....In a bizarre twist, Shakur, bleeding badly, sat on a couch and rolled a joint, witnesses said. Then he phoned his girlfriend, who contacted his mother, former Black Panther Afeni Shakur. Harrell called 911. Paramedics showed up minutes later. Police began interviewing witnesses. (interesting)
