My strong takeaway from the testimony so far is that he went in the house. From there, I only see inferences, and enough to make me think his demise must have happened in there. But all we know is he was found later on the lawn, dead.
But because none of that home or those people were given even the tiniest of investigation, I agree we don't have enough to pick a likely cause of his demise, or who did it or why.
The fact he could NOT have been hit by a vehicle forces us to know there has to be another answer for what we do see (JOK on the lawn with tail light pieces appearing there at some point or points in time). Even if we don't have proof, we know someone did something.
There's no blood on the lawn or clothes to speak of, despite injuries that hint at a lot of bleeding. Where did it go, outer space? If we look at possibilities nearby, how about a basement floor that no investigator ever even tried to see, and a bulkhead door that opened not far from where he was found??
Long ago (T1 days) I was one of the first to suggest that MAYBE it was just a freak accident involving a walk down the stairs and an unplanned attack by the dog and a fall backwards that cracked his head open and he died, with no one intending it. Or maybe there was an argument over KR with swings taken, and the dog jumped in to defend its master and uh-oh JOK is dead and now what? From which the others in the house panicked over the possibility of a major wrongful-death lawsuit and decided to put him on the lawn and try to explain it away. One thing led to another. Or maybe a less innocent scenario, in which that angry interaction over KR led someone to drunkenly, stupidly pick up a small dumbbell and whack JOK in the back of the head, and he fell dead, and now what do we do?
So the "motive" could be no thought-out motive at all. A dog that got out of control, or a drunk who did something very very stupid. Not planned. But led people to do all they could to make it look like something else.
Note that the only expert testimony we've had about the arm injuries themselves and what caused them is that it was from a dog. Those are still ahead in T2, but these are experienced people who are qualified to speak ...and cw witnesses do NOT dispute that it could have been caused by a dog.
Are those resulting narratives largely speculative? Sure. But EVERY possibility is largely speculative - tying together just a few facts here and there that give a hint of uninvestigated possibilities - once you have to eliminate KRs vehicle as the cause due to the science of how things move and the results of impact forces. And JOK could not have been hot by a vehicle to cause his injuries, that is a fact.
