The True Story of Netflix’s Cold Case: The Tylenol Murders
In late September 1982, seven individuals in the Chicago area died after ingesting Extra Strength Tylenol capsules laced with potassium cyanide. The victims included 12-year-old Mary Kellerman, 27-year-old Adam Janus, his brother Stanley and sister-in-law Theresa, 31-year-old Mary McFarland, 27-year-old Mary Reiner, and 35-year-old Paula Prince. The capsules had been tampered with after leaving the manufacturing facilities, leading to a nationwide panic and a massive recall of Tylenol products.
The Investigation, Aftermath, and Unanswered Questions
The investigation into the Tylenol murders revealed that the cyanide-laced capsules were placed on store shelves in the Chicago area, suggesting the tampering occurred post-manufacture. James Lewis emerged as a prime suspect after sending an extortion letter to Johnson & Johnson, demanding $1 million to stop the poisonings. Although he was convicted of extortion and served 12 years in prison, no direct evidence linked him to the murders.
The case prompted significant changes in the pharmaceutical industry, including the introduction of tamper-evident packaging and federal anti-tampering laws. Despite extensive investigations and various theories, the perpetrator remains unidentified over four decades later. The Netflix docuseries sheds new light on the case, exploring potential leads and the enduring impact on victims’ families and public trust in consumer products.
