In the documentary "Finding Amelia" there is reference to a piece of cloth with a knot tied in the middle that was found at the 7 site. I cannot find any reference to it any where here. What was the determination (if any) as to what, when, where it may have came from? Has the knot ever been untied? I was thinking that inside the knot might be a perfect place to find contact DNA, or even something tangable, like hair or a blood stain. If Mr. Noonan WAS seriously injured, maybe the cloth had been used as a tourniquet to bind a wound, or splint.
Can anyone point me at references to this cloth, or answer the question?
