Moving my thoughts to the appropriate thread:
I don't think it was possible, judging from the footprint and dust disturbance on the railing evidence gathered, that Rebecca went over the balcony railing on her own.
Looking at the photos of the railing, I am comfortable with a 3 1/2" - 3 3/4" disturbance as being the largest of the cleared areas. (I have estimated the disturbance areas for the hypothetical movements downward from the original post and added to it.)
The possible choices for Rebecca going over by her own will, for a person tied in the manner in which she was bound:
1. Sitting on the railing and maneuvering by pulling her knees to her chest and turning to place her bound feet on the other side of the railing, with her hands tied behind her back = contact with her rear and turning --> a much larger area would have been swiped clean, probably 15" - 16"
2. Going over sideways on her left side, head first = contact with her waist sliding down her hip to her thigh in order to achieve the shift of her center of gravity enough to go over ---> 9"-11" of completely cleared railing.
With her arms tied behind her back, this method would also require some rotation towards the front in order to accomplish.
3. Going over on her torso, head first = contact with her stomach down along to her hips to shift the center of gravity ---> 12" to 14" of completely cleared railing.
There would be no way to briefly touch the railing on her own because all of the head first scenarios involve shifting her weight and sliding in order to accomplish the shift of her center of gravity in order to go over.
The (at the very most) 5" total of complete clearing does not fit with any of these scenarios. (3 1/2" - 3 3/4" of complete clearing if you compare the daylight photo from the Sheriff's PP presentation with the tape measure at the railing, from erosion bump to erosion bump.)
The scenarios I outlined are the possibilities for a person of her height, tied in the manner that she was bound.
There are no toe or foot prints facing back towards the room, so that eliminates scenario #1.
She could not have gone over the railing backwards on her own. Her right foot toe prints were facing towards the rail on a slight diagonal to the right. There is a 1" disturbance on the rail closest to her toe print.
Also, she could not have gone over backwards with her right foot toe prints facing the rail, and her arms bound behind her back.
All other scenarios require leverage to overcome her center of gravity which would have been below the top of the railing.
There is no clearing on the railing larger than 3 1/2" - 3 3/4", eliminating the sideways and torso scenarios.
From the right foot toe print closest to the rail facing slightly to the right on a diagonal, the left hip would have been the only candidate for the sideways scenario.
Rebecca could not have gone over the railing of her own free will.
One question: Why would Rebecca have left the handle from the cord tied into the bindings?
