What I find very puzzling in the right autopsy picture: there is a second reddish circular mark/bruise around JB's neck below the cord. How did this mark get there? It seems it was not caused by the cord, for the cord is in another place. Had something else been pulled around JB' neck before? Or was the cord first pulled around JB's neck to strangle her, and afterwards the knot was tied? And as the knot was being tied, the cord was pushed upwards? I also read something in a crime fiction book which might explain the type of marks on JB too. From Donna Leon "Fatal Remedies", p. 127 (Donna Leon is a very popular crime fiction author here in Europe). [the victim, Mitri, has been strangled and there are two circular indentations in his neck. The coroner Dr. Rizzardi comes to the following conclusion in his report]: "The double mark on Mitri's neck was, he had determined, a hesitation mark on the part of the murderer, who had probably loosened the cord momentarily to tighten his grip, shifting it and thus leaving a second indentation in Mitri's flesh." Maybe something similar happened with JB? The perp tried to tighten his/her grip, loosened the cord and shifted it, and that's why there are two circular marks around JB's neck?
