The Tylenol Murders: A Crime That Changed America

In the fall of 1982, people across the Chicago area did something millions of Americans did every day—they took Tylenol.

Within hours, they were dead.

At least seven people were killed after ingesting Extra-Strength Tylenol capsules that had been laced with potassium cyanide. There was no warning, no visible tampering, and no obvious connection between the victims. What initially appeared to be a medical mystery quickly revealed itself as something far more terrifying: a random, invisible act of murder hiding in plain sight on pharmacy shelves.

In this episode of Three Voices One Crime, we reconstruct the Tylenol murders from the first unexplained deaths to the nationwide panic that followed. We examine how investigators traced the poisonings, why the crime was so difficult to solve, and how a single unknown offender forced law enforcement, corporations, and lawmakers to rethink product safety forever.

More than four decades later, the case remains officially unsolved.

No arrest.

No conviction.

Only a legacy of fear—and the safety seals we now take for granted.
