I just think it's more likely to have been some run-of-the-mill murder that an elaborate conspiracy.
I've e-mailed many sites that had articles about this, and the only one to respond with anything new was Jeff Rense, saying his sources (I guess) say the local coroner is very upset about 'normal procedures' having been circumvented in this case. I know he is not the most reliable of sources; just informing folks of what he told me.
E-mailed Boston Globe (among others) and their response was "Good Question", and that they had not checked on it for some time. They e-mail me back again in about 5 minutes, saying 'no new information'. Got the feeling all they did was do a google search!
