The SW says the doctor "expressed concerns made based on the -- the above factors, suffocation may have occurred prior to Shacknai's fall". (page 5 of the third thumbnail in the SW link).
What gets me about that quote is that he specifically says suffocation may have occurred PRIOR to the fall. How could he fall if he were suffocated?
If you could post the exact quote I would appreciate it as there are a lot of 'at first' and 'may' comments circulating. TIA!
