Host Olivia Lavo discusses how Susan Snow, a bank manager from Auburn, Washington, died suddenly after taking Extra Strength Excedrin on June 11, 1986. Her death was initially attributed to heart failure until a pathologist assistant detected the smell of bitter almonds, leading to the discovery of cyanide in her bloodstream.
