'Crazy' true crime documentary breaks into Netflix top 3 leaving people questioning one thing

A true crime documentary has soared into the top three shows on Netflix, but the haunting three-part mini-series has left people pondering one thing in life.

If you're looking for a gripping TV series you can binge in under two hours - 117 minutes to be precise - look no further than the latest work of directors Yotam Guendelman and Ari Pines.

"Before 1982, nobody thought twice about opening a bottle of painkillers,” the pair told Tudum, as they explained what their latest true-crime documentary is about.

"Today, every tamper-proof seal is a reminder of that dark moment — when cyanide-laced capsules transformed an everyday medicine into a murder weapon, permanently reshaping consumer industries.

"For more than 40 years, this case has been viewed through a narrow lens, locked onto a single theory while crucial evidence and promising leads were left unexplored. Perhaps that’s why, even after all these years, the case remains unsolved."

We're talking of Cold Case: The Tylenol Murders, which as of writing is number two in the top 10 shows on Netflix in the US - but I wouldn't put it past it reaching the top spot in the coming days.

In 1982, a series of poisonings took place in the Chicago Metropolitan area, Illinois, where seven people died after taking Tylenol Extra Strength tablets that unbeknown to them were laced with cyanide.

"With Cold Case: The Tylenol Murders, we’re taking a fresh look at this complex, haunting puzzle, shedding new light through overlooked evidence, unheard testimonies, and troubling inconsistencies," the directors added.

"Our hope is that by expanding the narrative, we might bring the families of the victims a step closer to the answers they’ve awaited for decades.”

Over on Twitter, fans who have watched the enthralling documentary shared how it resonated with them - with one person conceding that it has now left him questioning consuming over-the-counter drugs.

"#TheTylenolMurders on Netflix really make you question taking medication," they wrote.

While another typed: "As someone who takes pain meds at the littlest of inconvenience, the Tylenol Murders documentary on netflix was like a horror movie."

With a third penning: "The tylenol murders doc on netflix is crazy actually."

"The Tylenol Murders on Netflix was really well done. I’d listened to podcasts about the case but learned new information. What a scary case," added another viewer.

Among the victims of the killings, which has still not been solved, was 12-year-old Mary Kellerman, as well as Adam Janus, 27, Stanley Janus, 25, Theresa Janus, 20, Mary McFarland, 31, Paula Prince, 35, and Mary Reiner, 27.
