The Louis Zahn Drug Company's footnote in the history of the Chicago Mafia, led me to Cental DuPage Hospital. There, I found a clue that led me to the "smoking gun."
The "smoking gun" is indisputable proof that the Tylenol capsules were not laced with cyanide locally, at the retail stores. The "smoking gun" evidence obliterates the "approved theory" of the Tylenol murders that J&J, the FDA, and the FBI promoted to the public.
