Matt Mendenhall.
No, he's not dead but a number of years ago- almost 10 now- an interview with him appeared in a muscle mag. It was supposed to be an expose on all the problems he had as well as how it was that he never came to be a pro- without a doubt- one of the best bodies ever to never win a pro card.
It is mentioned in the article that Matt came down with some strange fungal infection that he just couldn't beat.
Now, seeing as how this was in a Muscle magazine, I have no idea if it is true or not.
