I have only been making reference to the depression left in the surface of the skin: the furrow.
And, I strongly disagree with your declaration that the depth of the groove is mostly from post-mortem swelling. See, my last post (140) above.

I dont think we really disagree over the issue,
AK. Youve simply taken exception to my wording, which might have been better were I trying to go into an in-depth answer. What I said originally was:
The deep ligature furrow was formed postmortem. It is not an indication of how tightly the ligature was pulled while she was being strangled. It forms as a result of the body's swelling, and the color is because of the ligature's effect on blood and other fluids under the surface of the skin.
Im sure this wont be a very appealing subject to most here -- a couple wonks droning on about the finer details of what happens when a person dies from ligature strangulation. So anyone is welcome to scroll on by if they so choose. Ill try to explain what I meant, and if the explanation isnt enough, or if I dont do an adequate job at it, well just have to leave it there rather than try to dominate the thread with our ramblings.
I have never claimed to be an expert on this or any other subject. Ive never been strangled, Ive never strangled anyone, and Ive never examined the body of anyone who was strangled. All I know is from the material Ive read. If you want to question it, you really should question the authors Im repeating. And I know I might misinterpret something, or misremember something, so I dont mind checking to see if Im correct about something I state.
We both know (as Im sure everyone here knows) that there would be no furrow, no discoloration of the underlying flesh, and no evidence of a ligature (other than its presence) if it was not tight enough to depress the flesh on a victim and compress the tissue enough to have any effect at all. But unless the tightening of the ligature was enough to cause immediate (acute) damage to her neck, it would leave nothing behind after it was removed (as you demonstrated in your video). However, left on for a long enough period of time, it would. Even on a living person, if it was left on for a long enough period of time it would have an effect. That effect would be different from the effect on a deceased person because of the different types of response.
If you notice in your video that when you tightened the cord, the surrounding flesh raised up because of the pressure applied at the ligature. Dead or alive, if it is removed at that point in time, the surrounding flesh would settle back down and there would be no furrow. But leave it in place for a long enough period of time, and the underlying flesh would be affected by the continued pressure. In a dead person, that effect would be the leaking of fluids from the cells under pressure into adjacent cells (
transudation). This would eventually result in the unrecoverable depression under the ligature (the
furrow) as well as the swelling of the surrounding tissue from the displaced fluids (
edema is actually the better term here because it refers to the process rather than simply the effect). Since we are only talking about the physical appearance of the furrow (
the depression left in the surface of the skin), this doesnt account for the discoloration of the underlying flesh from the effect on blood in the tissue which is usually considered a part of the appearance of the furrow.
If that same ligature is left in place (with pressure applied) until only shortly after death during the blanching phase, but before the full effect can be developed into a furrow, it would leave a white line where it had been (Ill have to look later for a reference somewhere to this being called an argent line). This is due to the blood being forced out from the capillary bed and venules at the surface of the skin which typically give it its natural color. Some of that displaced blood will burst from its vessels because of the additional pressure -- causing the petechiae we see underneath the furrow on JonBenets neck.
[You do know, dont you, that petechiae are more likely to be found above the ligature than below it. But please dont ask me to explain the reasons for that without first reading the sources I linked previously.] During the blanching phase, that blood does not return after the pressure is removed because of the halt in blood circulation. This is why I believe the ligature had been in the lower position when she died. We dont have a good enough picture showing whether or not the line is also present on her left side, but the one that does show on her right side and in the front are in an exact oblique angle toward the back as might be found in a partial suspension.
Looking back on your posts that I couldnt respond to while I was occupied with other things, I see I should touch on a couple more items:
While the furrow formation is essentially an after death phenomena I dont think it is correct to say that it is a result of the bodys swelling.
Youre right -- my bad. The wording I used should have been,
a result of the bodys swelling around the ligature. The ligature didn't cause her entire body to swell up.
Also, swelling cannot account for the ecchymosis, petechia, abrasion, etc.
Again, here we have to separate the furrow (or the groove remaining in the neck) from the coloration of the underlying flesh. Swelling has nothing to do with the color of the skin underneath, the petechial hemorrhages, or any possible abrasions. But then you said this in Post #142:
I have only been making reference to the depression left in the surface of the skin: the furrow.
If the ligature had been immediately removed, than a mark may have remained around the neck, but there would be no furrow. The furrow formed because the ligature remained around the neck after death.
Exactly. But if we are going to be parsing one anothers words, you should have said,
The furrow formed because the ligature remained around the neck long enough after death for the body to respond.
Things settle around the ligature: the flesh will move around to equilibriate the pressure around the neck, there could be transudation and accumulation of fluid etc., this all contributes to formation of the furrow, but I dont think these processes are necessarily swelling, at least not what one usually thinks of when contemplating the bodys swelling.
Maybe an illustration would help here. Attached at the bottom is a quick sketch I did in MS Paint that shows what I believe happens after a ligature is tightened around the neck. Three sketches: The first shows what happens in the moment a ligature is tightened. The tissue underneath is depressed causing the surrounding tissue to rise above its normal level. There is no furrow -- only the area underneath the ligature pressed below the normal surface of the skin (which will recover after removal). The second sketch shows what begins to happen a shortly after death. The ligature settles in deeper, surrounding flesh begins to settle (as you appropriately put it), and some edema (better term than swelling) begins forming immediately around the ligature causing it to become more hidden. In the third sketch, you see that the flesh in the area of the ligature has flattened out somewhat away from the ligature; but the ligature itself has continued to sink further into the flesh, and the flesh adjacent to it has swelled enough that it almost hides the cord itself. This third sketch hopefully shows what is described in the quote I provided earlier saying:
Occasionally, when the ligature is still in position when the body is examined, it may appear to be deeply embedded in the skin, sometimes almost out of sight, and on its removal a deep groove may be seen in the skin. This embedding may be accentuated by edema of the tissues, especially above the ligature. Presumably, some passive transudation of tissue fluid continues even after the circulation has stopped, and as such, edema may continue to develop to some extent even after death, accentuating the depth of the groove.
Referring to your video, you said:
Go back to that 30 second mark. What if I died right at that moment, with the ligature embedded in my flesh? The furrow which is already there would form such that it would remain even after the ligature is loosened. This is what is meant by the furrow being mainly a postmortem phenomenon. If Im alive, and the ligature is removed - no furrow. If Im dead and the ligature is removed furrow.
There is no furrow in your arm (or a neck) when you remove the ligature right after death. It is formed over time as the body reacts.
The furrow is caused by the compression of flesh as the ligature is tightened, and it remains after death because well, because youre dead.
The furrow is not formed simply because the person dies. It forms because the ligature remains in place long enough after death for the body to respond.
If I correctly understand what youre saying, you think that the argent line was caused by the initial strangulation, and that after death the cord moved from that position and into the position that we all see in the autopsy photos.
Correct.
The first linear mark is the furrow left by the ligature (garrote). This ligature was tightened sufficiently to cause the damage noted in the AR and that we see in the autopsy photos; therefore, she was alive when it was tightened in the position that we see it, and, the tightening of this ligature, in the position as we see it, is what caused her death (associated with...).
:waitasec: I dont think so. I believe the white line is from the initial strangulation where the ligature remained until after death when blood circulation stopped. After that, I believe the ligature slipped over her Adams apple where it remained until after she was removed from suspension. At that time, the ligature would settle and come to rest in the circumferential position where remained until it was removed by Dr. Meyer. (But thats just my theory -- we dont have to discuss that if you would rather not.)
Even if the ligature as we see was not the initial cause, it was the final cause.
If the second linear mark you reference is an argent line, than it was made post-mortem, after she was asphyxiated to death by the ligature. Which means that it must have been made by something other than the ligature.
Sorry if Ive not made it clear enough,
AK. I think she died from strangulation with the same ligature found on her neck where the first (IMO) white line is found. This caused her death (along with cerebral trauma from the head blow). Where we see the furrow is where I believe the ligature slipped upwards after she was already dead.
This line, such as it is, could simply be a product of lividity.
If the line is because of livor mortis, what caused it to not be present along that line?
DeeDee has suggested it might be from her head being turned. While I agree with her that a wrinkle in the flesh will certainly cause a white area within the lividity, I cant see that the angle of this mark would be from any natural crease in the neck. Indeed, in one of the books or articles I read it points out that a medical examiner can find out if that is the cause of a white line by moving the head to see if a natural crease forms along the line. Of course, we cant do that, and we dont know if Meyer did it (or even knew to do it).
What about the lines we see in the victims back? Are these argent lines? Or, are they simply products of lividity?
My guess is that they are either results of a natural crease from the bodys position, or because of a wrinkle in her clothes or the blanket underneath her.
I think the problem with interpreting the second linear line is that photographs are occasionally misleading and often difficult to interpret. There are two or three pictures relevant to this that are publicly available (I know, youve seen and studied them many times) and in each one this second supposed linear line appears differently more visible here, less visible there, etc. So, what does the AR say about it? Nothing.
Thats all true. But does the AR mention the white lines on her back that weve seen in the photos? Apparently Meyer didnt think any of that was important enough to mention, and without the leaking of the autopsy photos, we wouldnt know about any of them.
Is the second linear mark an argent line? Probably not.
If you are referring to the one on her neck, well have to disagree on that one,
AK. Thats fine -- most people do. (But thats my story, and Im sticking to it.)
