I have always thought it was number 1. I posted a huge article about this awhile back, with a severe head blow..a person bleeds from their nose, mouth, and/or ears...one or all of the above. I believe that Patsy flew into a rage, threw JB against something in the bathroom, maybe the sink or tub....(I have also posted articles that state that a child's skull is thinner than an adults, and that a child can crack their skull from just falling off of a bicycle.) Patsy screamed (the scream that the neighbor heard), John came running....they picked JB up and placed her on her bed....where she bled from ....most likely her nose....after the blow. And they tried to revive her there. Rope fibers were found in her bed...(I have read)....so, when they realized that she could not be revived....that is when...IMO...the staging probably began. IMO...they thought, because of her faint heartbeat...that she was ALREADY dead...when if fact she wasn't...when the garotte was twisted around her neck. (Right before my mom died...her heartbeat was so faint that even a nurse could not detect it....BUT....my mom was awake and talking...so of course she had a heartbeat at that time...just undetectable). Patsy and John were not doctors....so, if it is possible for a nurse to not be able to detect a faint heartbeat with a stethoscope....imagine how hard it would have been for the Ramsey's...to detect JB's....without one.
