As Steleheart had mentioned upsteeam, I think it's possible any blood might not be visible on the dark leaves, etc from a distance. Also, considering RL made the comment "pristine", iirc, and considering LE is investigating him, I'm not sure I'll take his words at face value at this time unail he is officially cleared by LE of any involvement.
Good thought about the bodies being intentionally placed there, though. I tend to think the possible assault and disposal locations are one in the same though, assuming a quick attack and murder as often happens in predator cases, assuming SA as a motive.
Now I do wonder if LE might suspect they were taken into a barn or RL's home and held overnight, though.
Eta: thinking about this further, being intentionally placed there, ARS admittedly placed Jessica Ridgeway's backpack and torso at 2 unrelated locations as a red herring, to deter the search away from him and his home. So, if somebody else close by there is responsible, that could be there motive, to concentrate the search there.
There is also the chance maybe there was the original intention to conceal or move the bodies, but didn't get the chance for whatever reason. Or maybe they were concealed...
You're like me in that as you are typing thoughts are flowing and you find new ideas as you go. That's why a forum like this can really help thoughts and ideas as we communicate.
I tend to think if that had been the murder site, and for sure the SA site they would have removed more leaves and dirt under the bodies and the scene wouldn't look so undisturbed. But that means a couple of people carrying them to put them there and while it doesn't look too bad coming down the trail from the cemetery I don't really know. It's what I think though.
