Do you have a source for the bone missing?? I had never heard that before. I know that when you list all the bad things that happened to her you may think it's too much of a coincidence, but believe me the list of random occurrences that directly resulted in the sinking of the Titanic is even longer. My point is, bad luck exists, plain and simple. None of what you mention proves foul play to be honest, I've never been to that place but from what I saw in The Killing Season her body was very close. If she had been in a place where it would have been impossible for her to arrive in foot then I could believe it but that is not the case. You can easily get to where she died just by walking. Why is that so suspicious? I don't understand. When you assume she was on drugs, and she probably was, everything you mention becomes plausible.
I accept there MAY BE a conspiracy with SCPD because maybe they were clients of hers, nothing more.
