Agree - in most respects the description of the pathological findings are accurate.
The only point I'd make is that it assumes that the victim is conscious at the time they were strangled.
If the victim were unconscious - either physically knocked out, or drugged, for example, then none of that would be likely to apply.
We have to keep open the possibility that Allison may have been either knocked unconscious (eg blood from nose in the car) or drugged (have the QPS actually got anything useful back from toxicology tests yet? Or did I read that there was nothing helpful?). In which case, she may not have caused any defensive wounds either to herself or to her assailant.
Just raising possibilities here - not facts. Not even a theory...

The description given by that poster is very good, accurate and quite apt. The
Logical reason for them to assume Allison was conscious is most likely due to unmistakable fact that GBC had wounds that may be consistent with defensive struggle by Allison. Of course they may be caterpillar or shaving cuts tho lol.
I agree it's possible she was drugged or unconscious. May account for the chipped tooth and bleeding but perhaps not. It's possible that she was drugged then suffocated with a pillow and kids didn't hear anything either evidence of this is compromised by decomposition. As redness on forehead, nose, chin is minimized after that amount of time . And, If so, the scratches are at odds if they do not resemble those consistent with what GBC maintains. and the reported screaming and argument need consideration also.
However, the post put forth seems to focus on the very real possibility she was conscious I suspect. Based on the scratches GBC has. It's a sound theory they postulate. Only the release of toxicology will shed more light on this. I of course do not know

I wasn't there and my kenmore dam fortunately wasn't involved
