Matthew Sheppard was a drug dealer.
Sheppard dealt in meth. For general review...meth customers/users don’t do a lot of thinking and if they get some idea in their head that their dealer is screwing them, then it won’t take much for the demise of the dealer. It took two years after this guy’s death for the general public to get this one curious aspect of his money-making enterprise. You would think that people would have asked about this a week or two after his death.
