CHICAGO — Forty years ago this week, what would become known as the “Tylenol Murders” started to tragically unfold in Chicagoland.

Over the span of three days seven people died from poisoning after ingesting cyanide-laced capsules of Extra -Strength Tylenol bought in local drugstores.

The case terrified Chicagoans, gripped the nation, and led drug companies to create safety-seal packaging for their products.

Police believe someone took bottles of Tylenol capsules from several grocery and drug stores in the area, filled them with the cyanide pills then put the tampered bottles back on the shelves.

The killer was never caught, and the case remains unsolved to this day.

In 1983, James W. Lewis, a former Chicago resident, was convicted of attempting to extort Johnson & Johnson, after he sent them a letter saying he would stop the Tylenol killings in exchange for $1 million.

A Chicago Tribune investigation has uncovered new information linking Lewis, now 76, to the murders, and you can hear more on their podcast here.

Below are the names of the victims who died from taking laced capsules between Sept. 29 and Oct. 1, 1982.

  • Mary Kellerman, 12, Elk Grove Village
  • Adam Janus, 27, Arlington Heights
  • Stanley Janus, 25, Lisle
  • Theresa Janus, 19, Lisle
  • Mary McFarland, 31, Elmhurst
  • Paula Prince, 35, Chicago
  • Mary Reiner, 27, Winfield
