I don’t think defensive wounds.
Hi PB, scratches from the disposal terrain seems to be the obvious possibility; I was al though just pondering her possible history of strangulation ("bruises on neck") and was thinking why and how scratches, if defensive wounds, could and would appear on the top of the hands--this would/could be one way.).
With that being said, this could be important for a wooded location vs a field, water or building location, etc....I am reminded of a case I just saw where there was an examination of post mortem scratches on a victim...while she was running through a wooded area, thorny bushes iirc, and sustained many scratches this way, it was able to be determined that some specific scratches were not caused by those branches, etc, but rather by fingernails.
I would assume LE obviously aptly noticed these scratches and photographed them (Standard Procedure).
Word of these scratches is important insight, moo, and brings me back to the bird in my avatar and somewhere possiboy similar to this nature preserve, which LE seemed to focus much on, moo.
EG also had that tree screensaver, been thinking about that again...
