I Watched Cold Case: The Tylenol Murders and Now I’m Side-Eyeing Every Capsule—Review

Lose Weight

I thought I was just pressing play on another Netflix true crime binge. Then Cold Case: The Tylenol Murders kicked down the door of my assumptions. I didn’t expect it to rattle my sense of safety, corporate trust, or the entire concept of consumer protection. But here we are—decades after cyanide-laced Tylenol killed seven people in 1982—and I’m wondering if we ever wanted this case solved at all. Cold Case: The Tylenol Murders isn’t just a documentary; it’s a scalpel carving through myth, media, and the mythology of justice. If you're searching for clarity, brace yourself—because what this series delivers is far murkier, and far more disturbing, than a smoking gun.

I Let Cold Case: The Tylenol Murders Ruin My Faith in Safety Seals—Review

The 1982 Chicago Tylenol murders: A nation’s nightmare in pill form

If you ever doubted that everyday objects could become instruments of terror, let me reintroduce you to the fall of 1982. One morning in the Chicago suburbs, 12-year-old Mary Kellerman takes Extra Strength Tylenol for a cold. Hours later, she’s dead. By sundown, two more are gone. Before anyone figures out what’s happening, the 1982 Chicago Tylenol poisonings claim seven lives—killed not by overdose, but by cyanide.

The scariest part? No one saw it coming. This wasn’t a targeted hit. It was the kind of horror that slipped through your front door inside a bottle you trusted. The randomness is what rattled America to its core. This wasn’t just a crime—it was a psychological gut-punch that ruptured the illusion of safety in the most mundane of rituals: taking painkillers.

From panic to packaging reform: What changed forever

Once the cyanide-laced capsules were traced to store shelves, chaos erupted. Parents flushed pills down toilets. Drugstores pulled Tylenol en masse. Johnson & Johnson’s Tylenol recall escalated from a corporate crisis to a nationwide emergency response. Their brand had gone from household staple to public enemy number one.

The chaos wasn’t just PR. It cracked open a national debate on corporate responsibility and the illusion of product safety. So how did Tylenol murders change packaging? With seals, tamper-evident tape, and the now-ubiquitous child-proof caps. Safety features we treat as background noise today were born in direct response to the fear that one madman with a toolkit and a grudge could hack the system.

This wasn’t just a pivot in pharmacy logistics—it was a cultural inflection point. Every safety seal you’ve broken since is a ghost of that panic.

Why this case remains unsolved after 40 years

The trail of errors, assumptions, and wrong turns

You’d think a case this high-profile, with seven bodies, national press, and full-blown FBI involvement, would have wrapped neatly by now. But no—the Tylenol murders remain unsolved, and not for lack of attention. Instead, they’ve become a case study in how investigations collapse under their own weight.

Let’s start with the Tylenol murders timeline. The deaths happened fast—over three days. But connecting them took time, and by then, crucial evidence had already evaporated. Capsules were discarded, bottles tossed, scenes cleaned. It took the clustering of three deaths in the Janus family to even register that this was a coordinated attack.

And once the scope became clear, the panic did what panic always does—it made people sloppy. Leads flooded in. None panned out. And the few suspects that did emerge? More on that circus in a second.

The suspect that sucked all the oxygen out of the room

Every crime story needs a villain—or at least a likely one. James Lewis, who sent an extortion letter to Johnson & Johnson demanding a million dollars to halt the killings, became the prime suspect. But here’s the twist: despite being the obvious Tylenol murders suspect, Lewis was never charged with the murders themselves.

Instead, he served time for extortion, and then… nothing. He remained the focal point of the investigation, drawing resources and attention despite only circumstantial evidence. Focusing on Lewis prematurely narrowed the investigation’s scope. And the result? A deadlock.

The FBI’s case file on the Tylenol murders remains a classified archive filled with missed opportunities and uninvestigated leads. Rumors persist about other suspects, including a paranoid dockworker with a chemistry hobby. But the system had already committed to its theory, and in true bureaucratic fashion, never pivoted.

So here we are, four decades later, with a story that feels frozen in time. A story where the victims are real, the terror was widespread, and the killer—whoever they were—vanished like vapor.

Cold Case The Tylenol Murders

Cold Case on Netflix: A franchise built on unfinished justice

True crime, now with sequel potential

Netflix has transformed unsolved crimes into serialized existential dread, and that is meant as a compliment. Their Cold Case series is less about closure and more about poking holes in official narratives. The Tylenol murders are a perfect fit. No resolution? Even better. Netflix loves a mystery that refuses to be solved.

This isn’t just about murder—it’s about America’s inability to deal with uncertainty. Think of this entry as the spiritual cousin to the JonBenét Ramsey episode: haunting, open-ended, full of dead eyes and unanswered questions. The series features a polished aesthetic, tight pacing, and delivers moral outrage wrapped in stylish dread.

Berlinger’s fingerprints and the Netflix signature

Of course, this wouldn’t be a proper Netflix docuseries without Joe Berlinger’s involvement. The man behind Conversations with a Killer and the Ted Bundy Tapes brings the same sleek, haunting editorial flair to this series. His involvement in Joe Berlinger’s Cold Case series guarantees we see a slow, detailed examination of systemic failure rather than a simple rehash of old news.

This installment hits hard by fitting seamlessly into the larger Netflix Cold Case franchise. It’s less “Who did it?” and more “Why didn’t anyone figure it out?”—a subtle shift in focus that turns the spotlight away from the killer and onto the institutions that let them slip through. This is not a crime drama; it is a high-quality indictment of institutional failures.

So yes, Netflix’s Cold Case is compelling viewing. But it’s also frustrating, unresolved, and quietly furious. And that’s exactly what makes it great. It dares to ask a question Netflix seems increasingly obsessed with: What if we never get the ending we want?

Breaking down the series: Episode-by-episode deconstruction

Episode 1 – “Pain Killer”: When horror went over the counter

The first episode opens with clinical calm—and then detonates. Twelve-year-old Mary Kellerman takes Tylenol for a cold. By the end of the day, she’s dead. And she’s not alone. The Janus family, just trying to manage a headache, ends up losing three members in a matter of hours. It’s not just tragic—it’s cinematic in the worst possible way. The horror creeps in not from a killer’s face, but from a bottle on your bathroom shelf.

This is where the series gets its claws in. The editing smartly mirrors the creeping dread of the real-life moment—slow realizations, disconnected deaths, then the revelation that they’re linked. The horror isn’t in gore. It’s in silence, in the fact that the victims had no idea they were swallowing poison. And the audience? We’re right there, watching as the puzzle forms and the dread deepens.

Building dread without a villain

Here’s where the first episode distinguishes itself from the dime-a-dozen true crime assembly line. There’s no lurking killer. No sketch artist composite. Instead, we get a hauntingly precise approach that roots us in the everyday details—who bought what, when, and where.

The victims aren’t footnotes. They’re given space—especially Mary Kellerman, whose story embodies the chilling randomness of cyanide poisoning through Tylenol. And the show doesn’t milk their grief; it honors it. There’s no gore porn here—just fear, precision, and a creeping unease that’s more Hitchcock than headline.

This episode doesn’t just start the story—it detonates it. And by the end, you’re not just watching a documentary. You’re side-eyeing your own medicine cabinet.

Episode 2 – “The Bitter Pill”: The case against James Lewis

The extortion that hijacked the investigation

Enter James Lewis: the man who couldn’t resist writing himself into the narrative. The second episode goes full procedural, retracing the bizarre trail that led law enforcement to their prime suspect—not because of forensic evidence, but because Lewis mailed a letter to Johnson & Johnson demanding $1 million to stop the deaths. Lewis’s extortion letter wasn’t just a red flag—it was a hand grenade lobbed into the middle of an already panicked investigation.

The doc drills into Lewis’s past with the obsession of a profiler. His criminal record, his aliases, even his DIY print shop vibes—all of it is treated like damning context. But here’s the thing: evidence of guilt? Still missing. The FBI had no smoking gun, just a man with a flair for theatrical threats and a deeply suspicious timeline.

And that’s the push-pull tension this episode handles so well. You want to believe he’s guilty—he practically volunteers for the role. But the further the doc digs into the allegations against Lewis in the Tylenol murders, the more you realize how little hard evidence there actually is.

The suspect who wouldn’t go away

Lewis’s presence in this episode is part ghost, part narcissist. He dominates screen time, even when he’s not talking. The interviews are chilling in that uncanny way where someone gives you all the right facial expressions but none of the emotional weight. It’s here that the documentary lays out the most bizarre contradiction: Lewis is simultaneously the most obvious suspect in the Tylenol murders and the least provable.

As investigators explain their obsession with him, you can feel the frustration mounting. No confession. No DNA. No one saw him near the crime scenes. But still—he wrote that letter. And now, decades later, we get the unsettling bonus of watching Lewis’s final interview before his death, a surreal coda to what became his last media appearance.

The episode plays fair, but also sharp. It lets you sit in the discomfort of ambiguity, knowing that the man who might’ve done it also might’ve just loved the attention too much to resist.

Cold Case The Tylenol Murders

Episode 3 – “Sealed for Your Protection”: Tampering theories and corporate shadows

The contamination theory they didn’t want to hear

By the time we hit episode three, the doc shifts gears—from whodunnit to whodidn’t. This chapter is less about suspects and more about systems. Specifically, it explores whether Johnson & Johnson’s Tylenol recall was reactive enough—or if it covered up a more damning truth: that the poisonings might’ve originated inside the supply chain, not from random tampering at stores.

The theory? That cyanide entered the capsules before the bottles ever reached shelves. It’s a narrative that’s mostly been sidestepped in official investigations, but the doc doesn’t shy away. Interviews with skeptical experts and authors build the case. And while it never outright accuses, it raises deeply uncomfortable questions about Johnson & Johnson’s corporate responsibility.

The most compelling moments here aren’t dramatic—they’re logistical. You start thinking about how many people touch a product before you do. And suddenly, the documentary is less about crime and more about trust.

How safety became a marketing strategy

The final section of the episode connects the dots to modern-day consumer behavior. Remember those triple-seal caps, shrink wraps, and tamper-proof bottles? Yeah, they didn’t exist before 1982. The Tylenol case didn’t just inspire reform—it forced it. And it turned corporate panic into a new industry standard.

This is where the doc lands its final thematic punch. The history of tamper-evident packaging isn’t a safety innovation. It’s a reaction to fear. And that shift—from trusting products to distrusting them by default—is framed as one of the most significant cultural aftershocks of the case.

This episode isn’t out to prove who did it. It’s out to prove that the system, from production lines to public messaging, was fundamentally changed. And whether or not we know who slipped cyanide into those capsules, we all live in the aftermath.

By the end, the killer is still a question mark. But the consequences? Those are written on every safety seal you’ve ever cracked open.

Casting the crime: Real people, raw emotions

The families who never stopped grieving

It’s one thing to be the subject of a headline. It’s another to keep living after the world moves on. Michelle Rosen’s connection to the Tylenol murders isn’t just a chapter in a documentary—it’s the unhealed center of the whole case. Her mother was murdered by a product trusted in millions of households, and decades later, Michelle’s pursuit of answers still simmers with quiet rage and bottomless grief.

She’s not a plot device, not a “talking head.” She’s the connective tissue between what happened and what refuses to fade. And if you’re thinking, “Surely the authorities gave her closure,” welcome to the circus. Michelle has become something like a citizen detective, a reluctant advocate forced into that role by institutional shrugging and bureaucratic fog. You hear her speak and immediately realize that stories from Tylenol murder survivors don’t end—they just get quieter, more complicated, and more determined.

The Janus family and the anatomy of grief in motion

Then there’s how the Tylenol murders devastated the Janus family—a tragedy so absurdly cruel it feels like a bad rewrite. Three family members, gone in a blink, all from the same poison bottle. If Michelle’s grief feels surgical and precise, the Janus story lands like a gut punch with no warning. Their presence in the documentary doesn’t just serve as emotional ballast—it forces the viewer to stop thinking like a crime buff and start feeling like a human being.

There’s no melodrama in how they speak. Just exhaustion and a gnawing sense that justice ghosted them somewhere around 1982. These victims of the Tylenol murders aren’t statistics. They’re the ongoing consequence of a system that lost the plot and never quite picked it back up. And that’s the genius of this part of the doc—it doesn’t push emotion, it lets it haunt the frame.

James Lewis: The enigma behind the camera

Showman or sociopath? Reading James Lewis’s face

Let’s talk about the guy who hijacks the room without even showing up on time: James Lewis, the alleged mastermind—or theatrical red herring—behind the poison panic. The doc knows how to shoot him: low light, high tension, close enough to see the twitch. But it doesn’t tell you what to think. That’s your mess to sort out.

Watching Lewis is like watching a man perform sincerity with subtitles turned off. He doesn’t sweat. He poses. He answers questions the way a magician misdirects—just enough sleight of hand to keep you guessing. Is he the prime suspect in the Tylenol murders or just someone who read too many true crime novels and wanted a cameo? The ambiguity is intentional. The doc presents him less like a villain and more like a question mark with a mailing address.

And here’s where it gets good: if you’re wondering who killed the Tylenol murder victims, this isn’t the show that hands you an answer wrapped in red string. Lewis isn’t a confession away from closure—he’s a decades-long itch the case can’t stop scratching.

How Cold Case tackles the Tylenol murders—through a lens of discomfort

So how does the documentary frame all this uncertainty? By leaning into it. It doesn’t try to force a conclusion. Instead, the Cold Case approach to the Tylenol murders becomes an exercise in psychological interrogation. Every scene with Lewis builds tension without payoff, and that’s the point. The unease isn’t just about whether he did it—it’s about the way he smirks like a man who enjoys being almost-believed.

He’s not innocent. He’s not proven guilty. He’s a walking PR nightmare who knows exactly how to bend narrative gravity around himself. The doc doesn’t overplay its hand—it just hands you the deck and lets you sit in the discomfort of watching a man both too obvious and too slippery to nail down.

Lawmen, reporters, and rogue pharmacists: A documentary cast worth bingeing

Suits, scopes, and suspicious scripts—meet the supporting cast

Look, true crime lives and dies by its side characters. And this one’s stacked like a prestige HBO series. You’ve got veteran FBI agents who look like they walked out of Zodiac, forensic analysts who treat every pill like a murder weapon, and rogue pharmacists who make you wonder what else is hiding behind the counter.

These aren’t filler interviews. They’re the scaffolding that holds up the narrative maze. One moment, you’re staring at crime scene photos from the Tylenol murders, the next you’re watching a criminologist explain cyanide absorption rates like it’s dinner conversation. The effect? You’re constantly ping-ponging between “I’ve got it figured out” and “Nope, I’m lost again.”

When the press becomes part of the puzzle

And then there’s the media. Not the TMZ-style circus, but the real boots-on-the-ground journalism. The Chicago Tribune’s Tylenol coverage at the time wasn’t just reactive—it shaped how the public processed the horror. The doc gives these reporters space to reflect, and it’s a reminder that journalism, at its best, doesn’t just chase headlines—it drags truth into the light, kicking and screaming.

One segment in particular highlights how forensic evidence from the Tylenol murders was interpreted (and misinterpreted) under media pressure. Turns out, the story isn’t just what happened—it’s who told it, how loudly, and whether anyone was really listening. The result? A rare moment where the press isn’t just covering the mystery. They’re part of it.

This is true crime’s unsolved mysteries done right: not by playing Clue with real bodies, but by showing just how many people are still trying to answer questions that should’ve been settled 40 years ago. The killer might be unknown, but the impact? Very much still present.

Truth in the Edit: The Directors’ Lens and Legacy

From “Shadow of Truth” to Cyanide Capsules: Guendelman and Pines Evolve the Genre

If you’ve seen Shadow of Truth, you know what Yotam Guendelman and Ari Pines excel at in their documentaries: they build a moral labyrinth that keeps you on edge. These filmmakers reject tidy conclusions. They thrive on controlled chaos—editing choices that spark more questions than they answer.

When they turned to Netflix’s Cold Case: The Tylenol Murders, their aim wasn’t to unmask a culprit. It was to ask, “How far are we willing to go before we hit our limits?” And they deliver exactly that. They lean into their strengths—exploring grief with thriller pacing and weaving ambiguity into the narrative as a deliberate device.

Visually, they still favor long takes, ambient unease, and news clips used for tension rather than simple exposition. What’s new is their confidence. They’ve moved beyond just proving themselves in the true crime arena; they’re redefining it.

Defying genre conventions in Netflix’s true crime lineup

Had this been another Netflix documentary chasing views, you’d see title cards every minute and moody lighting spelling out “unsolved = spooky.” Instead, Guendelman and Pines embrace negative space—pauses loaded with tension, incomplete thoughts, scenes steeped in moral murk. They never manufacture urgency; they let it build naturally. This method trusts the audience and treats justice as an organic narrative, not a prebuilt plot.

By rejecting formulaic templates, they’ve crafted something that transcends a mere mystery. Their work reads as an indictment of institutional breakdown, wrapped in the guise of entertainment. It stands out as one of the most quietly revolutionary entries in Netflix’s expanding catalog of true crime.

Method over drama: Securing James Lewis’s final word

The production strategy behind that last Lewis interview

The trickiest move here was landing James Lewis’s final interview without turning it into a spectacle of guilt or grandstanding. They succeeded—without ever staging a mock courtroom.

We don’t know exactly how they secured access (presumably through strict NDAs), but it was no grab for headlines. It was a tactical operation: patient preparation, precise framing, and the refusal to treat Lewis as the story’s ultimate reveal. Instead, he becomes the final thorn in a narrative already full of them.

Many documentaries fumble big interviews by being too soft or veering into sensationalism. Not this one. Lewis isn’t lionized or goaded into a confession. He stands as the unreliable narrator of his own story, making the result haunting and oddly administrative—like hearing someone fact-check his own legend.

A review defined by restraint, not spectacle

This distinction separates a solid documentary from one with something meaningful to say. A typical review of Cold Case: The Tylenol Murders might lean on breathless conjecture or scattered clues that lead nowhere. Here, the directors avoid cheap theatrics. They trust the inherent eeriness of the events.

Their restraint is deliberate. Lewis speaks, but it’s the silences that carry the weight. The editing never shouts “gotcha”—it slips around any impulse to dramatize. The result provides what most Netflix true crime coverage overlooks: clear-eyed context without sensational spin.

This isn’t another clickbait addition to Netflix’s 2025 true crime roster. It’s a masterclass in treating a villainous mystery as a question mark, not a smoke alarm.

Product safety, public trust, and the cost of negligence

When regulation rewrote itself in real time

This isn’t merely a tale of cyanide-laced capsules; it’s a story of supermarket panic. Before 1982, the idea that store-bought Tylenol could kill you was unthinkable—like someone tampering with your toaster. Then the poisonings happened, and suddenly product safety and true crime were inseparable.

That crisis didn’t just shock the FDA—it transformed it. Regulations weren’t simply amended; they were reborn. Tamper-evident packaging went from novel idea to necessity overnight. The basic trust between consumer and commodity was shattered and rebuilt.

The film keeps that history front and center, framing the 1982 tampering legislation not as overkill but as a vital survival mechanism. Safety seals stop feeling like a nuisance and start feeling like scars no one notices until they’re gone.

Johnson & Johnson’s PR crucible

Then there’s Johnson & Johnson’s emergency response. The company pulled Tylenol from shelves, took the financial hit, and set a new standard for preemptive crisis management.

But the documentary sidesteps the corporate-hero narrative. It asks tougher questions: Did J&J move fast enough? Was there any cover-up? How much of their response was genuine accountability, and how much was brand triage?

Here, the directors play historian. They trace how the Tylenol case reshaped packaging norms, altered consumer behavior, and changed our default assumptions every time we crack open a pill bottle. The murderer was never caught, but their legacy endures. Every seal you break is a tiny act of trust restored.

What the ending really reveals (and what it deliberately withholds)

Misdirection in the finale: What we see—and what’s conspicuously absent

If you prefer stories with neat wrap-ups, the finale of Netflix’s Cold Case: The Tylenol Murders was designed to leave you unsatisfied. This isn’t like Mare of Easttown, where a big reveal brings catharsis. It plays more like Zodiac—a slow-burn descent into uncertainty with no clear exit ramp.

When viewers search for explanations of the series’ ending, they’re really seeking the closure the directors never intended to grant. Guendelman and Pines treat ambiguity as a character. Instead of tying up loose ends, they scatter them like mines and step back. We see fragments—archival clips, voiceovers, a slow zoom into emptiness—because certainty isn’t their goal. Doubt is.

This isn’t lazy storytelling; it’s intentional withholding. The directors play their cards like Fincher: the facts may be out there, but they’re more interested in how we cope with their absence. It’s not about unanswered questions so much as unmet needs.

Fan theories and the conspiracy deep dive

When a story leaves gaps, speculation rushes in—often via Reddit threads that read like an ’80s conspiracy zine. Skimming theories about the Tylenol poisonings shows how quickly fans fill the void.

Some zero in on corporate sabotage; others revive the copycat scenario. A few even suspect that Johnson & Johnson planted an insider on the packaging line. These theories range from plausible to wildly far-fetched, but they all serve one purpose: they let viewers feel like active investigators.

And the series invites it. Suggestive edits and clipped interviews drop breadcrumbs—but when it comes to whether the case was ever solved, the show simply shrugs. It offers a firm no wrapped in a gentle maybe.

The ending isn’t closure. It’s a provocation—a final act of viewer manipulation that leaves the lights on, the door ajar, and your mind racing.

After James Lewis: Confronting a dead end

Post-mortem frustration: A case left open

With James Lewis gone—dead, silent, and still a mystery—the Tylenol poisonings case becomes unsolvable by definition. Lewis was the perfect true-crime suspect: theatrical, ambiguous, strangely camera-ready. Now that we can no longer question him, investigators lose their main thread. No trial. No confession. Just decades-old FBI files missing their final chapter.

The documentary leans into that void. There’s no last-minute twist, no fresh evidence, no post-credits revelation. It acknowledges that closure might be the one thing this story will never provide.

That choice shows rare restraint. The film doesn’t guess at what Lewis might have said. It doesn’t dramatize his death. It lets the silence speak—and in true crime, that quiet honesty can cut deeper than any sensational headline.

An unforgiving legacy for families

For the victims’ families, that silence is brutal. When people seek answers about the Tylenol poisonings, they echo the voices of loved ones—Michelle Rosen’s family, the Janus relatives—still waiting, still grieving. Lewis’s death brings them nothing but fresh pain.

So the narrative remains suspended—deliberately, maddeningly, permanently. The story of James Lewis and the Tylenol murders ends without a period. It’s the missing piece at the heart of the mystery.

Perhaps that unresolved ending is the most honest way to tell this tale. The documentary doesn’t pretend justice was served or imply it ever could be. Instead, it turns the camera on us and dares us to live with our discomfort.

No killer brought to account. No final reveal. Just the lingering echo of one of America’s most unsettling unsolved cases.

Season 2? What we know and what’s circulating

Netflix’s sequel calculus: ratings first, then the buzz

Netflix isn’t in the business of neat endings—it thrives on binge-worthy suspense and social-media fervor. So when whispers of a Cold Case comeback surface, it’s not idle gossip but pattern recognition. Recall how Making a Murderer scored a second season after igniting Netflix’s algorithm, or how Tiger King clawed its way back even after its story lost momentum.

The real question isn’t whether Netflix wants to renew Cold Case, but whether the series delivered the numbers. Early data suggest Cold Case: The Tylenol Murders ranked among Netflix’s top true-crime hits of 2025. Audiences clearly crave revisiting historic wounds through slick reenactments and suspenseful narration.

What might a follow-up season explore? It won’t rehash the Tylenol case. Expect a fresh mystery with the same narrative DNA—an unsolved, morally fraught crime, perhaps from the ’90s or even an international case with geopolitical intrigue. If Netflix aims to retain its crown as the home of compelling true crime, it must serve up something equally dark and addictive.

And yes, if the original team reunites for another 2025 Netflix documentary, we’ll be back at the crime scene once more.

Cold cases as content gold: the economics of unresolved crime

Here’s a secret few admit: cold cases make irresistible television. Their open-ended nature allows for endless serialization. Their unresolved mysteries spark outrage, which drives engagement. And they leave room for timed “revelations” just when the hype starts to fade.

Netflix knows this well. They’ve turned unsolved trauma into prestige TV. While it may sound cynical, it mirrors a cultural shift: viewers prefer stories without tidy conclusions. Wrapped-up endings feel contrived; cliffhangers feel authentic.

So yes, if there’s profit to be made and a passionate fan base, renewal odds are high—especially if the Tylenol story delivered on the metrics. In 2025, unresolved justice isn’t just a storytelling tool; it’s a business strategy.

New leads, sealed files, and mounting public pressure

The documentary’s real-world wake: what’s shifted

On screen, Cold Case remains clinical and measured. Off screen, it’s stirred a storm. Since the series premiered, journalists have scoured old records, and online sleuths have been dissecting the Tylenol murders’ FBI files like it’s a full-time pursuit.

It’s not just armchair detectives at work. Requests for unreleased documents under FOIA have surged, and whispers of overlooked copycat cases are circulating. That’s the strange power of true crime in the streaming era: it turns viewers into amateur investigators, and sometimes that collective noise forces action.

Whether it yields genuine breakthroughs is another question. But the fact that FOIA clerks are scrambling speaks to the show’s real-world impact.
