I think you may be confused because Dr. Michael Zimpfer can't keep his story straight. First he says [there] "was no evidence of poison" and then further down he states, [the symptoms] "do not correspond to the clinical image of an illness." So, if it's not poison (food or otherwise) and it's not an illness, what is it?? Body snatchers from Pluto?
Actually I believe it was poisoning. I was uncertain about YOUR position on it.
I agree with you about Dr. Zimper though.
