Are we sure it is both stab wombs and blow to head? If blow to head only, could it be someone threw her down the wall? Is there a high wall in that area where someone literally could have picked her up and thrown her?
EXTREMELY unlikely, but if just a blow to head, could she have accidentally fallen off the wall while taking pictures? Perhaps not watch where she was going and trip and fall over the wall? This would be assuming stab wound is not there. If there is, this would be eliminated.
If body was only there for a week, does that mean someone had her for a few days? Or is the science on that just in exact
It does not seem we know what valuables she had on her. It does not appear to be much. It is extremely unlikely someone randomly kill someone in broad daylight for an ipad without someone hearing a scream, etc...She looked like a tall women too so I think she would have put up a big struggle...and been pretty good at that too.
