I heard he possibly contracted the HIV virus by using caverject which left a hole in the tissue of the male sex organ after injecting, then had unprotected sex, don't know if this is true but when he was filming the movie rocky 5 he slept with a different woman every night, his time in Hollywood during that movie kind of sealed his fate because he was always living that life out and it just led him down a bad path, the lifestyle was just a precursor to what was to come!
