...
one of them isn't necessary."
A quote I can't seem to attach to its original author, but, one that comes to mind when I find myself askew to someone like my good friend JWG, with whom I'm typically in agreement. In this case my perspective on the potential stain in the trunk outline is slightly different.
In the interest of full disclosure, this is an area where I have demonstrated less than stellar abilities. The crime scene photos held
all kinds of stuff in my view that it turns out... just weren't there. :bang: So...expecting just as much to be off as on - I submit to you what I'm seeing.
On the left below is the unretouched image. On the right is a copy of the image I have colorized to highlight what appears to me to be the outline. I have tagged some elements of the anatomy that should help you to recognize the overall positioning. Aside from adding the color and labels I have not modified the image in any way.
A description of what I'm seeing is the body in a crouching/fetal position with the points of greatest pressure (hip, shoulder, elbow & abdomen) demonstrating the most intense white (in the original). With the body laying essentially on one side with the upper torso slightly twisted such that the chest and abdomen are lying on the carpet. The torso is lying on top of what would be the left arm (mirror image) with the elbow located just behind the small of the back and the forearm passing across the abdomen and the hand(s) indistinguishable, but, positioned in what would be the lap area. The knee would be positioned over the hole in the wheel cover and the foot positioned somewhat in an on-the-toes fashion.
In this scenario the head would be resting on the section of carpet closest to the fender (not in this image as it is only of the wheel cover). IOW...the top of the image is where the shoulders would be located.
