I've heard many theory's about tupac but does anyone believe and have good evidence of his existance?
If you believe he did die...why do people think he is still alive (as with Elvis)
No, he's dead. You can probably find his autopsy photos on the net somewheres. People still think he is alive because he apparently faked his death
two or three times before he actually did die. I'm not sure if he actually did fake his death those times, or if it was just a myth.
