In 1982, seven people died after taking Extra-Strength Tylenol that had been secretly laced with cyanide. The poisonings unfolded across multiple Chicago-area communities before investigators realized they were facing a deliberate act of product tampering. This episode traces the case chronologically, explores why the investigation stalled, and examines the psychological impact of a crime built on anonymity and randomness.

This episode is a Crown Noir production and was written, researched, and produced by A.C. Roberts.
