One scenario is he existed the car and was leaning down to vomit (which was all over him) and she hit the back of his head with the spine of the tail light, as he braced himself his right arm ended up in the wheel well and was dragged a short distance backward, and then forward when she completed the turn.
If the tail light was able to reach and hit the back of JOK’s head wouldn’t that imply or also make us consider the damage the car could likely cause, especially when we consider the speed and weight of the reversing vehicle, severe and painful injuries to his upper back and upper rib area, right shoulder and neck?
Wouldn’t the strike against his head and likely upper back, shoulder, neck and right rib area also be forceful enough to cause his body fall towards the curb and possibly onto the street or to his knees? If so imagine there would be medical, forensic or pathological evidence of such a terrible event on JOK’s hurt body unfortunately. Same too could apply if he dragged in any way against the gravel, lawn or curb as KR continued to drive on in this scenario. What are the chances he would have even been be to keep his head and neck up during this terrifying ideal? Very low, I would think, if he has already been rendered incapacitated by the fractures to his skull? Perhaps instead, investigators and pathologists would find more markings and injuries, such as drag marks and clinging gravel, on the anterior surface of JOK’s head and neck or the palmar part of his hands.
Since ME implied that the extensive skull fractures would have rendered him unconscious immediately I don’t think he would even have the moment to brace himself if the car struck the back of his head first.
Additionally, if he was dragged while the car continued to reverse wouldn’t there unfortunately be a risk of him or one his limbs, like his leg in addition to his ankle and foot, being run over by one of the tires? Such injuries not only often cause tremendous pain but also fractures, open wounds, blood loss and markings on one’s clothes, such as imprints from the tire, that would have surely been noted and investigated or captured the attention of the ME, assisting pathologists and responding friends, family and LE.
The critical things is that there are only 2 ways that you get tail light pieces on the ground and on his shirt with his DNA on the tail light.
Unfortunately, it is possible that due to the inadequate, incompetent and below standard collection and maintenance practices regarding the evidence related to JOK’s case, I think cross-contimination could be considered a reasonable cause for how pieces of the tail light ended up on JOK’s shirt unfortunately.
DNA found on KR’s car is not that of blood or some other vector that could indicate the tail light was involved in causing the beloved officer harm. For example, perhaps the DNA collected was gathered using touch or trace evidence.
Since they were a couple, perhaps JOK and KR often drove around together in her vehicle and just the action of him possibly opening or closing the trunk door regularly to gather their things or leaning against as they took moment to chill around and talk. In that time a piece one’s hair could shed and land against the vehicle’s window or bumper or due to chance or friction of it being pressed against the car, one’s hand to shed and leave enough microscopic epithelial cells as trace evidence used to yield a to get a DNA sample. Not to mention just like they would anywhere else people sneeze, sweat and talk if not in their cars than in the immediate vicinity of them leading to another opportunity to collect trace DNA evidence.
