Yes, I agree. But as far as that last point- holding the nose/mouth shut- possibly there WAS a mark from twisting the red turtleneck, but even more likely, IMO is this:- with NO visible cause of death, all they had was a dead/dying child. How did she die? An autopsy would certainly have been needed, and revealed the molestation (after all, she bled from the vagina- SOMETHING caused that- something not within the scope of normal activity for a 6-year old). I think that by making the (erstwhile) garrote, they hoped an autopsy would not be thought necessary. After all, there was now a very obvious cause of death. What they did not realize is that autopsies are mandatory in ALL suspicious deaths, and in ALL child deaths, suspicious or not.
