okay this is what I got from the hinky meter review of Rebecca's autopsy:

Based on that info at hinky meter, that's why I thought that Rebecca had been alive prior to her hanging. I wasn't relying on info provided by the LE at all, they've given me enough reasons to doubt them so I have a hard time taking in what they say at face value. I was thinking she had been knocked out first which would explain the subgaleal hemorrhages and then thrown over the balcony while unconscious, rather than being killed and then hung on the balcony.
Yet she had no injuries to her spine, despite the 9 ft long drop, and fractures to her neck bones (hyoid bone and thyroid cartilage) that are more commonly found in strangulation than hanging. It's not actually common to have fractures of hyoid bone and thyroid cartilage in hanging, but I guess it doesn't rule it out.
