So assuming that both of the pathologists were excellent, qualified, and experienced (we know that the hired one is, and no reason to believe that the one that did the autopsy is NOT).. and assuming that the coroner is also excellent, qualified, and experienced, then why do you figure it took a month to come to that same conclusion?
My guess is that LE were leaning in a certain direction, while pathologist#1's findings may have left room for doubt on either suicide or murder... and in the event that there are 2 possibilities, I believe the coroner must find that the manner was 'undetermined'.. which would, I'm sure, be considered totally unacceptable, can you imagine if that had been the determination?? Not good, imho.
Then suddenly, after almost a month, police FINALLY, after a big newspaper piece, actually spoke to pathologist#2.. and only days later, police held their press conference with the determination of double homicide..
This is the part that for me anyway, seems very coincidental in terms of the timing, but that is just my opinion (and apparently also that of some others who have written articles??).
