I started a long post to this on Fri, but got pulled away and I thought I saved it but it didn't save, and I don't feel like looking up all the research I did so I'm going to try to wing it. For this I did a quick google search and I apologize for not saving my sources that I had on a much longer post.
I might not understand biology properly but if JOK was dead, how could blood pump to his hand to form a bruise? How could an IV work without blood circulation unless he was having his heart pumped. And they would have had to perform that hours after he died, and all thru the time EMS showed up, got him to a hospital and into an ER.
Bruising can appear on a dead body as uncirculated blood pools in the extremities.
Lividity (Postmortem Stain):
As blood circulation stops, blood pools in the lowest parts of the body, causing a reddish-purple discoloration that looks like a bruise.
- Lividity( blood pooling) starts appearing within a few hours of death.
- It's initially not fixed, meaning the area will blanch under pressure and shift with body position.
- After about 4-6 hours, the lividity becomes fixed, meaning it doesn't blanch and shifts with body position.
In some cases, bruises have been found to appear after death, even several hours later.
- The time it takes for livor mortis to become fixed can vary.
- Other observers have noted a different time sequence; lividity becoming apparent from 20 minutes to 2 hours after death, reaching maximum intensity in 6–9 hours and becoming fixed from 3 to 5 days.
- After death, blood stops circulation stops and blood pools in the area closest to the ground.
- The capillaries in the dermis are occluded by the surrounding fat as it solidifies, preventing the blood from moving.
There are a few reasons a bruise can form: Medications, nutrient deficiency, diabetes, and several other diseases and procedures that don't have any baring on this that we know of. I think we all can agree that trauma seems the most logical explanation for the bruise on his hand. But if blood has stopped circulating then the bruise wouldn't form from trauma, but from lividity. So therefore the bruise on JOK's hand could not form from the trauma of the IV needle OR the trauma happened BEFORE death! If you look at the autopsy photos ( which I'm not going to post here) there is a bruise on JOK's hand starting in the middle of the hand and going down to around the 1st knuckle on his pointer finger. So that bruise either happened when JOK was hit by the car or by some other incident. A fight perhaps, or a fall or a defensive action from something that he was trying to get away from. The point is we don't know exactly and that to me raises doubt. One of the avalanche of doubt I have about KR hitting him with her car.
I had a lot more on this that went into could the bruise indicate of the body was moved. If lividity was the reason for the bruise was it caused by the way he was laying there in the snow and if he was propped up at some point but I think I made my point above. This is my understanding of things and I may be wrong.
