You know what else? It seems to me the body could quickly and easily be identified as GB or not through dental records. The complete autopsy isn't needed for that much to be done.
So why isn't this being done, or if it has, the results announced? Why would LE drag out the agony of not knowing even longer for the already-grieving families?
Something does not make sense here. Well, a lot of things don't, actually.
Maybe the victims head was missing. (cut off and dumped somewhere else.)
