Something I've found over the years, not just here, is that many people have a hard time accepting that bad things can happen to the best people with no logical explanation. When a young child is missing, hurt or worse, accusing the parents of being neglectful or otherwise endangering the child is the first thought for many. When something happens to a young adult, it seems to be blamed on being involved in drugs, gangs, prostitution, depression or otherwise putting themselves in danger, and/or a friend or family member must be into one of these things and that's what caused the problem. In some cases, I agree that one or more of these things may be likely, but I just don't see it in this one.
I don't believe TB's death was because he was buying/selling drugs, being initiated into a gang, being hazed because he was joining a frat, or murdered by one of his friends. My problem is that I keep coming up with all kinds of things that I don't think happened, but can't come up with even one that I really believe is likely.
