would you do that if you were directly linked to a major supplier who was netting a few million a year from this college? Do you think that LE and parents would leave it at that you could just go about your business after that? The next logical step in that scenario is not that you walk free, but that people come forward and say you are a supplier. Then you get a felony charge for dealing and are put in a position to serve hard time or rat on your supplier. That all goes through that person's head in a few seconds, they know the score and the outcomes. The third choice is to eliminate as much evidence as possible, including the body. Now, even if people do come forward and say you were a supplier there is no evidence and so no conviction. In all cases your operation you are out of business. However, in one outcome you are dead, in another outcome you are in prison and your life ruined, and in the third, you are free but have to look over your shoulder and clean up your act.
I see people persistently finding it hard to believe that people would hide a body of a friend if they OD'd. Yet many others posted all sorts of examples of that. At the same time, it's as though they have no idea how crime organizations function. Most criminal activity involves conspiracies. People acting totally alone are the rarity not the norm. No one involved in criminal activity wants to serve time and so a lot of things are done to prevent or reduce that possibility.
