Edinburgh is pronounced incorrectly throughout the entire episode.
The Cyanide/Tylenol murders in Chicago actually occurred in September and October 1982, not 1986 as referenced by Rossi.
In 1986 in Washington state, Stella Nickell laced Excedrin with poison to murder her husband. She also killed Sue Snow this way (whom she did not know) to prevent detection by creating the same panic of the 1982 Tylenol murders. This is the case Rossi is referring to when stating they killed another victim to distract from the real target & not the 1982 Tylenol murders.
