Vader was a friend of a friend, and a Forum admin on a forum I used to frequent.
He was the founder of Teckademics (http://www.teckademics.com/, http://www.myspace.com/teckademicsapparel) , (Co-?)Founder of Pornstar Clothing (http://www.pornstarclothing.com/), as well as the somewhat Co-founder of the Mischief street racing series (www.mischief.tv).
He died of a heart attack 11/14/2011, which has been confirmed through his family and friends, but i cannot seem to find an article ('Sean Murphy' is a very common name), or his actual facebook/Myspace. I do know he lived in LA (or did, anyways), so that might be where he died.
If anyone could help find any of his profiles or a News article/Obit, I'd be greatly appreciative.

RIP Vader. You will be missed.
