Netflix’s latest true-crime docuseries Cold Case: The Tylenol Murders peels back the sealed lid on one of America’s most terrifying unsolved cases. This three-part series, out on Monday, tells the story of seven people who died suddenly in Chicago in 1982. The cause shocked the country, each victim had taken Tylenol that had been poisoned with cyanide.

The case caused panic across the United States. People rushed to throw out their medicine. Shops pulled products from shelves. The police launched one of the biggest investigations in American history. But more than 40 years later, the crime is still unsolved.

Directed by Yotam Guendelman and Ari Pines (Shadow of Truth, Buried), and produced by true crime veteran Joe Berlinger (Conversations with a Killer), this latest entry in Netflix’s Cold Case series offers more than a history lesson. It reopens a case many thought was closed. The series questions what really happened, and whether the truth has been hidden all along.

The first episode sets the scene powerfully. We hear the voices of the victims’ families and emergency workers. One paramedic remembers walking into a home and finding two people dead within minutes. The only clue: a bottle of Tylenol. These real-life stories make the series deeply human. It’s not just about crime. It’s about real people whose lives were destroyed in an instant.

The filmmakers say this case deserves a new look. For years, the focus has been on one man: James Lewis. He sent a letter to Johnson & Johnson demanding money to stop the killings. He was jailed for extortion, but never charged with murder. This series digs deeper. It questions whether police were too quick to settle on one suspect, and whether leads were missed or ignored.

The series presents new testimony and evidence. It also looks at inconsistencies in the investigation. Could the killer still be out there? Could there be more to the story, even a possible cover-up? These questions make the series feel urgent, even today.

The production is tight and professional. Old news footage, haunting 1980s images, and a slow, tense soundtrack give the series a dark tone. But the story is always clear. It never feels confusing or exaggerated. The directors let the facts speak for themselves.

Cold Case: The Tylenol Murders is more than just a true crime documentary. It’s a serious investigation into a case that still haunts America. It’s also a reflection on trust, fear and what happens when safety is shattered. The series is emotional, well-researched and deeply thought-provoking.

Whether you’re new to true crime or a regular viewer, this series is worth your time. It may not solve the mystery, but it brings us closer to the truth and reminds us why some questions must never be forgotten.
