More than 11 victims, a killer on the loose, and a mystery unsolved for over ten years in the Long Island area (New York). “Gone Girls: The Long Island Serial Killer” tells the chilling story of the Long Island serial killer, a mystery that haunted the quiet suburbs of Long Island for more than a decade, now brought to life in the gripping Netflix docuseries “Gone Girls: The Long Island Serial Killer.” This three-part series delves into the heartbreaking investigation and the systemic failures that allowed the killer to evade justice for so long.
A Decade of Mystery
In 2010, a woman named Shannan Gilbert disappeared under strange circumstances after calling the police while being pursued by a man and terrified during a service. But Shannan’s case was not the only one. Between 2007 and 2009, four women—Maureen Brainard-Barnes, Megan Waterman, Melissa Barthelemy, and Amber Costello—disappeared, and their bodies were discovered near Gilgo Beach. These women, known as the “Gilgo Four,” were all sex workers, a fact that contributed to the initial dismissive attitude of law enforcement and the media. Were we facing a new Jack the Ripper? The police seemed to downplay all the cases, which initially appeared isolated and unconnected.
But there was much more, as there was a serial killer on the loose in the Long Island area. One case led to another—all victims, all women, and all sex workers. It is estimated that there were more than 11 victims.

The Breakthrough
The docuseries captures the spectacular breakthrough in the case when, in 2023, an arrest is finally made. Rex Heuermann, an apparently normal architect from Massapequa, was identified as the alleged killer. This revelation was a shock to many, including those who had tirelessly advocated for justice.
Liz Garbus, Creator of the Series and Director of a Previous Film on the Subject
Liz Garbus, who had already chronicled the popular efforts to solve these cases in her 2020 film “Lost Girls,” revisits the story, focusing again on the families and the systemic problems that plagued the investigation. The film starred Amy Ryan and featured Gabriel Byrne in its cast.
Systemic Failures and Family Struggles
“Gone Girls: The Long Island Serial Killer” not only recounts the investigation; it also exposes the corruption and administrative failures within Suffolk County law enforcement. The series presents a vivid picture of how bureaucratic procedures and a lack of urgency allowed the killer to remain free for so long. Through interviews and archival footage, the series gives voice to the families who fought against a system that seemed indifferent to their plight.
A Hope for Resolution
As the series progresses, it becomes clear that the families’ hope is not only to find the killer but also to receive answers and closure. The series poignantly captures their ongoing struggle and the emotional burden of the long wait for justice.
