(Warning-- some may find these comments too graphic or disturbing.)
Regarding the extent of injuries to her neck-- they were hardly what I'd describe as minor, or moderate. Her SCM muscles and strap muscles were essentially torn in half on one side. They also include evidence that her heart was beating at the time (significant hemorrhage at the torn muscle sites documented in the AR, which would have looked different if her heart had not been beating at the time of the muscle tears). Many years ago I also posted that I thought that with the lengthy drop it was amazing she wasn't decapitated. (Sorry for the gruesome detail.)
Because of the injury pattern-- both tearing of the muscle and soft tissue structures, with concurrent circumferential crush injuries to her larynx, I believe she was alive with a beating heart (perhaps semi conscious or unconscious, from blows, and/ or perhaps partial/ incomplete strangulation) when she went over the railing.
As to the force applied to get her over the railing-- tossed, tipped, somehow lowered down at the end of the rope, IDK. But the "hanging or raising her from below" theory about "staging" her hanging never reconciled with her neck injuries for me. I also think that the AR injuries could indicate she wasn't entirely limp at the time of the hanging (was moving against the rope, either involuntary reflexes, or in the last seconds of consciousness)-- and if so, that could account for the circumferential crush injuries to the larynx.
Not all long drops produce cervical fractures, and Rebecca didn't have cervical fractures. There is plenty of discussion in the literature about that. Some believe that the absence of cervical fractures means she couldn't have experienced the long drop.
I'll look forward to the medical examiner's testimony (Cyril Wecht, IIRC), but also recognize that this level of detail may not be brought up in this case. These kind of details might be less appropriate for the level of evidence in a civil trial, IDK. I'm recalling Mr. Greer's interview comments where he said they had to make decisions about what to present, and not all details, lab tests, and experts were necessary for them to win their case.
Rest in peace, Rebecca-- lots of people are on your side fighting for you, and love survives the grave.
