Just as Cynic has stated previously, the Tugboat Hitch requires 3 wraps around a bollard, in this case a neck.
IMO, RZ's murderer stood behind her, NOT facing her, and looking down at the back of RZ's head while she was seated with her legs taped to the wicker chair. Thus the knot began with the rope under her chin rather than behind her neck.
Looking at Cynic's excellent illustration of the damage to RZ's neck as per the AR (Illustration 1), IMO the X criss cross furrows on the back of her neck well below the ligature furrows that angle upwards towards the ligature knot were a result of the first 2 tugboat hitch loops.
Illustration 1: Cynic's interpretation of the AR. Thank you, Cynic!
The final (3rd) rope loop/wrap and knot (the ligature) would then be yanked upwards with the snap of the 9 ft drop. The first 2 rope loops/wraps remain at neck level, as illustrated in Cynic’s video (Illustration 2).
Illustration 2. Stop frame from Cynic's excellent Tugboat Hitch video. Again, many thanks, Cynic!
When tying the Tugboat Hitch around my own neck, front to back, rather than back to front, then flipping the rope to create the double hitch knot, the two loops remain in place, horizontally across my neck, even after applying force on the knot and tightening the knot by pulling upwards.
They do NOT move upward with the knot.
Note: when creating the two loops directly below my ear, then looping the third time and applying the double hitch, the two original loops crossed over each other behind my neck.
This would also explain the X criss cross at the back of the neck as reported in the AR as well (see Illustration 3). The 2 crossed-over loops being BELOW the knot/ligature furrow would also explain the 1-1/2 x 1-1/4 inch group of apparent petechiae in that area, which were a result of the pressure imposed by the 2 stationary loops in the tugboat hitch knot.
Illustration 3: The furrows that would result from a Tugboat Hitch used in hanging IMO
Tying the rope OVER RZ’s long hair, rather than directly on her skin, was a clever move as it helped “soften” the continuity of the furrows, thus resulting in irregularities and gaps in the furrows. This scenario fits the wounds as documented in the autopsy report.
Among evidence items the Zahau family is suing Gore and the SD county is the video of the autopsy.
Why has the autopsy video been withheld? I would imagine (presume?) the family received autopsy photos of some nature or other. If not, I once again would presume the photos would be included in the evidence law suit. Quite simple to be selective and biased in selecting what to photograph, whereas a video is/should be continuous. Any gaps in the video would be beyond suspect.
I am an experienced rock climber. I can make knots in my sleep. I grew up sailing. I had never seen the Tugboat Hitch before, and even with Cynic's excellent video and online resources, it took me several hours to figure this one out, primarily since i had to keep starting over and adding more and more rope in order to have enough to add the double hitch at the end, and also to leave an additional 6-1/4 inches of rope.
The tugboat hitch requires more than double the amount of rope needed to make, for example, a simple hangman's noose.
IMO It is virtually impossible to make a tugboat hitch without a bollard. I tried. Doesn't happen.
IMO the use of a tugboat hitch rather than a simple hangman's noose is an enormous FLY IN THE OINTMENT for the defense. The
video of the autopsy, when presented to the jury, will prove
unequivocally that RZ did NOT and COULD NOT have inflicted this upon herself.
