No, I dont think Markus Ruhl is dead, unless it was this year, he was training for the Mr O last year.
Goblin, I think you are talking about that d**k with the synthol arms. I dont know the guy personally, but I think hes a mockery to the sport and comes off as a *****e in the documentary (which was all about steroids, and didnt once mention his synthol abuse).
Oddly enough, hes also in the upcoming documentary 'Bigger, Badder, Stronger' which is kind of a Morgan Spurlock-esque take on bodybuilding and the impact of steroids.
Sorry if the above sounds a bit irritated, but if you've ever seen the documentary about him, he just comes off like a total a-hole, one minute trying to gain sympathy, the next showing off the video of how he was draining blood and tissue from his infected bicep to the local gym guys.
