To my mind, the defense experts collectively established that:
1) The theory of the CW that the only area of contact between vehicle and JO was one arm, striking just the immediate area of the tail light, was completely debunked.
2) That any contact between JO and a vehicle traveling in reverse would not have thrown his body the distance from where the CW indicated he was struck, and where he ended up on the lawn.
3) That any contact between JO and any vehicle, at any speed over 10 mph, would have resulted in many more injuries, of greater severity, spread over a larger portion of his body, than those that were identified during autopsy and were shown in the photography they reviewed. In essence, the CW-ME could offer nothing to dispute that.
4) That the nature of the death injury was such that, JO could not have been struck on the back of his head and subsequently walked or crawled to his final location, that he would have been knocked flat and in the absence of some input that caused him to move, he would have stayed where he landed.
5) There was no object in the immediate area of his final location that would be consistent with the head injury.
There was considerable additional, some of which represented opinion even if it was expert opinion. But summarizing from the above, some unidentified party or creature, either assaulted JO very near to where he fell or moved JO to his final location. Assuming they could cause the blow to the back of his head, I suppose a bear or some very large dogs could do that; but barring that, the supposition would be that a second party had to be involved. MOO
In the face of what the defense presented, and in order to renew the charges against KR, it seems the CW needs to believe (and prove) that the 110 lb KR moved the 220 lb JO to that final location without leaving any identifiable trail in the surface of the lawn....not even a trail of blood. Seems like that effort would have been witnessed because it would take some time and KR would have had a bunch of cleaning up to do because there would be a lot of blood involved. MOO but it doesn't really fit...And we know the rest of that platitude.
I suppose the CW could go looking for some animal DNA when they haven't found any but some pig skin to this point....
