No, your memory is fine! Among those who have suggested strangulation is the neurologist who worked longest and most closely with her, Dr. Hammesfahr. He pointed out that she had the persistent stiff neck which can readily be associated with attempted strangulation. The way I reconstruct it, Michael must have held her head down with his left hand. That is a quasi-strangulation, although the great damage must have been done by the sheer weight of him on her back, preventing her from breathing.
Terri was found face down with both arms underneath her, pointing upward towards her throat. She may have been reaching up to try to get his hand off her neck. It would have been hopeless...
I do not know if Dr. Hammesfahr ever had a chance to look at the bone scan report and reconstruct the crime using that. The damage and fractures shown by the bone scan must be accounted for in framing a theory of how Terri was injured.
And let's make no mistake, it was a crime.
Sure it was a crime. And over and over again Michael has publicly revealed that he is that he is a liar, sadistic, and vindictive - and paranoid as shown by the way he went after Republicans no matter that the senile and/or corrupt Judge Greer is also a Republican and catered to his every whim. Michael seems get great pleasure out of causing pain for others.
