Netflix’s Unbelievable: The Quiet Revolution in Rape Investigations That Started with Two Cops Who Actually Listened

DENVER — Six years after its 2019 premiere, Netflix’s Unbelievable remains the gold standard for true-crime storytelling that refuses to exploit trauma. The eight-episode limited series, created by Susannah Grant, Michael Chabon, and Ayelet Waldman, is not a whodunit. It’s a how-to manual disguised as a gut-wrenching drama—one that exposes the catastrophic cost of disbelief and celebrates the rare, life-altering power of being believed.

At its core are two parallel investigations separated by three years and 30 miles of Colorado asphalt. One ends in betrayal. The other ends in justice. Both are true.

2008: The Case That Broke Marie

Lynnwood, Washington. Eighteen-year-old Marie Adler reports being raped at knifepoint in her apartment. The details are horrific: a masked intruder bound her with her own shoelaces, photographed her, and threatened to post the images online if she called police. She did anyway.

What followed was a textbook failure. Detectives fixated on inconsistencies—normal in trauma survivors—pressuring Marie until she recanted. Her foster mothers, already skeptical, turned on her. Police charged her with false reporting. The real rapist, Marc Patrick O’Leary, walked free to strike again.

Marie’s story, first told in the Pulitzer-winning 2015 ProPublica/Marshall Project article An Unbelievable Story of Rape by T. Christian Miller and Ken Armstrong, became the series’ emotional spine. Played with devastating restraint by Kaitlyn Dever, Marie is not a victim archetype. She’s a kid who liked Foster the People, worked at Costco, and just wanted to be normal—until the system decided her truth was inconvenient.

2011: The Detectives Who Changed Everything

Golden, Colorado. Detective Stacy Galbraith—renamed Karen Duvall in the series and played by Merritt Wever—responds to a rape call at an apartment complex. The victim, college student Amber Stevenson, describes a nightmare eerily similar to Marie’s: masked intruder, shoelaces, hours of assault, photos.

Galbraith’s first move? She asks if Amber wants her in the room. “Take your time,” she says, voice soft but steady. No judgment. No rush. Just space.

In Episode 2, this 11-minute interview scene—filmed in one continuous take—functions like a masterclass. Duvall checks comfort levels, uses open-ended questions, and never interrupts. When Amber struggles to recall the rapist’s smell, Duvall doesn’t flinch. “That’s okay,” she says. “Memory does that.”

Across town in Westminster, Detective Edna Hendershot (renamed Grace Rasmussen, played by Toni Collette) is working a similar case. The two connect the dots: same pink yoga mat used as a blindfold, same threats, same meticulous evidence collection by the perpetrator. O’Leary wasn’t just a rapist—he was a collector, storing trophies in a garage shrine.

The series intercuts their dogged investigation—late-night stakeouts, cross-referencing 1990s rape kits, analyzing tire treads—with Marie’s unraveling life. The contrast is brutal. While Duvall and Rasmussen treat victims like humans, Marie’s original detectives treated her like a suspect.

The Real Heroes Behind the Badges

Stacy Galbraith and Edna Hendershot are not TV inventions. They’re the real deal.

Galbraith, then 32, had been with Golden PD for five years. Her husband, David—a sergeant in nearby Westminster—was the one who suggested she call Hendershot after hearing about a similar case at a domestic violence conference. “It was like puzzle pieces,” Galbraith recalled in a 2024 Zoom interview from her home in Grand Junction, where she now trains new detectives. “You just knew.”

Hendershot, a 28-year veteran with a smoker’s rasp and zero patience for bullshit, brought the grit. She’d seen too many rape cases go cold. “I wasn’t going to let this guy disappear,” she said. Their partnership—two women from different departments, different generations—was unprecedented. No ego. Just results.

Their breakthrough came from a surveillance photo: a white Mazda pickup with a unique tire tread. Hendershot ran the plates. The owner? Marc O’Leary, 32, a former Army medic with a spotless record. Inside his home, police found the pink yoga mat, Marie’s driver’s license photo, and DNA from five victims across two states.

O’Leary pleaded guilty in 2012. He’s serving 327½ years in Colorado—effectively a life sentence.

The Aftermath: A Reckoning That Never Fully Came

Marie received a $150,000 settlement from Lynnwood in 2014. The detectives who coerced her recantation faced no discipline. One later promoted.

But Unbelievable didn’t let that stand. The series ends with Duvall and Rasmussen visiting Marie—not to gloat, but to apologize on behalf of a system that failed her. In real life, Galbraith and Hendershot did exactly that. Marie, now in her 30s and living under a new name, told ProPublica in 2019: “They gave me my life back.”

The show’s impact was immediate. Rape report rates spiked 20% in some jurisdictions post-premiere, per a 2020 DOJ study. Police departments from Seattle to Sydney adopted “trauma-informed interviewing” protocols based on Duvall’s techniques. The National Sexual Violence Resource Center now uses Episode 2 in trainings.

Yet gaps remain. Only 31% of rapes are reported, per RAINN. Conviction rates hover below 1%. And “Stand Your Ground” laws—highlighted in other recent true-crime docs—continue to shield predators who claim fear.

Why Unbelievable Still Matters in 2025

In an era of Dahmer shockumentaries and Quiet on Set trauma porn, Unbelievable refuses to sensationalize. The rapes are never shown—only their aftermath. The camera lingers on Marie’s trembling hands, Amber’s hospital gown, the detectives’ tired eyes. It’s not about the violence. It’s about the work—the quiet, grinding, human work of justice.

Critics called it “anti-outrage.” Creator Susannah Grant told Variety in 2019: “We didn’t need to scream. The facts scream for themselves.”

Viewers agree. On X, #Unbelievable trends annually on its premiere date. One viral thread from 2024: “Watched Unbelievable in police academy. Cried in my car. Changed how I take statements forever.”

The Final Verdict

Unbelievable isn’t just a series. It’s a blueprint.

It proves that empathy isn’t soft—it’s strategic. That listening isn’t passive—it’s investigative. That two cops who treated victims like people caught a serial rapist who evaded entire task forces.

Marc O’Leary is in prison. Marie is healing. Stacy Galbraith and Edna Hendershot are training the next generation.

And somewhere, a detective is watching Episode 2—learning how to ask, “Are you comfortable?” before changing a life.

Unbelievable is streaming on Netflix. If you watch one true-crime series this year, make it this one.
