I suspect that if she had a known health problem, nobody would have had to go through the contortions of inventing the highly-flammable radiator fluid theory.
Exactly correct. That would have been the FIRST thing released.
Now I would not be surprised if they said “she was a diabetic and didn’t know it”.
What they have been trying to determine is the cause of death. They may know some underlying problem without making her medical history public.
If she had one of the two problems I mentioned, and they had been the sole cause of death, they wouldn’t be looking for another cause.
It would have been easier if they had pinned it on a health problem.
BTW, heart attacks take place more frequently around this time of day
Of course, if that had been the problem, the cause of death would have been rather evident.
