Top 10 Documentaries About Mysterious Disappearances

#10: “Gone Girls: The Long Island Serial Killer” (2025)

Long before human remains were found along Gilgo beach in 2010, many women had already gone missing across New York and Long Island. This three-episode documentary dives into the chilling Long Island Serial Killer case, but refuses to treat victims as mere headlines. Instead, Liz Garbus brings the same human-centered approach that made her film “Lost Girls” so powerful. It moves beyond Shannan Gilbert (whose disappearance drew national attention), widening the lens to include other overlooked victims. The result is a narrative that’s both gripping and heavy. More than just the mystery, it exposes botched investigations, corruptions and systemic neglect that allowed Rex Heuermann to evade capture for years. By the end, you’re left asking “why were these women ignored for so long?”

#9: “MH370: The Plane That Disappeared” (2023)

In March 2014, Malaysia Airlines Flight 370 vanished while flying from Kuala Lumpur to Beijing with 239 people aboard. To this day, no one can definitively explain what happened to the aircraft or its passengers. If you’re new to the mystery, this three-part documentary is a solid starting point. It reconstructs the night the plane disappeared and the global investigation that followed. Each episode offers different theories—some grounded, others more speculative. You won’t walk away with clear answers, but it’s undeniably entertaining. But then again, not everyone was satisfied. The first episode was pulled in Vietnam over concerns about inaccuracies in its portrayal of events.

#8: “The Imposter” (2012)

We still can’t make sense of it. Why would anyone pretend to be someone’s missing son? We’re talking about French trickster, Frédéric Bourdin. In 1997, he convinced a Texas family that he was their teenaged missing son, Nicholas Barclay—even though he was 23 at the time. This wasn’t a one-off deception. Bourdin had a history of impersonation, and might’ve continued to fool everyone if a private investigator and FBI agent hadn’t exposed him. This documentary doesn’t end there. Through interviews, including the imposter himself, it raises unsettling questions about the Barclay family. Why did they choose to believe Bourdin? Was there something they didn’t want uncovered? The deeper the documentary digs, the stranger and wilder it becomes.

#7: “Cropsey” (2009)

From Joshua Zeman and Barbara Brancaccio comes this haunting documentary. It opens like a folktale about a boogeyman named Cropsey, a faceless figure said to snatch children and vanish deep within the forest. But instead of dwelling on myth, the film pivots into something far more disturbing—the true story of Andre Rand, a man suspected of abducting and killing several minors - a living, breathing boogeyman. The filmmakers trace his history, profile the lost victims, bring in experts along with those connected to the case, weaving it all together with moving archival footage. The film’s conclusion strongly implies Rand’s guilt—a bold move that stirred controversy and leaves you unsettled long after the credits roll. That risk is what makes “Cropsey” so powerful.

#6: “The Disappearance of Maura Murray” (2017)

To this day, no one really knows what happened to Maura Murray. In 2004, after crashing her car on a rural New Hampshire road, she vanished. No clear answers, no confirmed sightings. Her disappearance became one of the first major cases to gain traction in the early social media age. This 2017 documentary dives deep, following investigators as they retrace their steps and uncover overlooked details. It brings together family members, witnesses, close friends and law enforcement in a thorough examination of the case. Exploring theories from voluntary disappearance to foul play, it exposes the gaps in timelines and police response. Sadly, it builds a mystery that refuses to be solved.

#5: “Crime Scene:The Vanishing at the Cecil Hotel” (2021)

The facts surrounding the death of Elisa Lam are truly sad. She vanished in 2013 while staying at the Cecil Hotel Los Angeles and was later found dead. This Netflix documentary revisits the case, casting chilling light on the infamous hotel while exploring the themes of mental illness and online obsession. It will honestly creep you out and leave you feeling sorry for Lam. The series is at its best in the final episode, where it turns the lens on internet detectives – people who confidently dissected the case and falsely accused an innocent musician. Still, the film was criticized for prioritizing conspiracy over hard evidence. But for crime junkies willing to overlook that, the series offers a haunting experience.

#4: “Who Took Johnny” (2014)

The mysterious disappearance of Johnny Gosch is no new case, especially for true crime fans. But whether you know the story well or are coming to it fresh, “Who Took Johnny” has something to offer. It provides an absorbing look at how the young boy vanished in 1982 while walking his paper route. But beyond the mystery, the film forces viewers to confront the unbearable, ongoing pain of a family who never got closure. Most harrowing of all, the film pieces together with sobering confidence what likely happened to Johnny—and it’s honestly too dark to imagine. But as nothing is certain, it leaves you wondering how much of it is evidence and how much is belief.

#3: “Girl in the Picture” (2022)

This one’s a true bombshell. At first, it begins as a tragic but straightforward story about a woman found dying at the roadside. But the real mystery is yet to begin. As investigators dig deeper, they unravel something far more disturbing—the true story of Suzanne Sevakis, a girl who went by many names. Abducted as a minor by Franklin Delano Floyd, a convicted murderer, she was raised as his daughter, sexually abused and robbed of her identity. Well-constructed and stomach-churning, “Girl in the Picture” follows how Suzanne’s story was uncovered decades after her suspicious death. As disturbing as it is, it’s a story that deserves to be told. It pays tribute to a young woman whose entire life was stolen from her.

#2: “The Disappearance of Madeleine McCann” (2019)

Bold and controversial, this docu-series takes a deep, almost exhaustive dive into the disappearance of Madeleine McCann. In 2007, McCann disappeared from a holiday apartment in Portugal while her parents dined at a nearby restaurant—and was never seen again. There have been investigations, speculations and media frenzy ever since. This series examines all of it with the case at its center. Though it may come off as repetitive at times, it clarifies misconceptions and adds new information, particularly through what private detectives uncovered. Thanks to that, you might begin to see the McCanns in a different light. Unfortunately, the McCann family wanted nothing to do with the documentary for fear it may hinder active police investigation.

#1: “The Keepers” (2017)

Catherine Cesnik was a nun and teacher at a Catholic high school in Baltimore who vanished in 1969. Months later, in 1970, her body was discovered near a garbage dump on the outskirts of the city. Despite decades of investigations, her case remains unsolved. This seven-part documentary will give you so much to think about. It examines the victims’ experiences, the church’s cover-up and the damage done by Joseph Maskell and other priests. It will leave you sickened with how they got away with abuse for years and genuinely heartbroken for the victims. But there’s a powerful thread of hope running through it, driven by Cesnik’s former students who refused to let the truth stay buried. That determination is the soul of the series.
