Introduction
Netflix’s latest true crime sensation, Gone Girls: The Long Island Serial Killer, has gripped audiences with its harrowing exploration of the Gilgo Beach murders, a case that haunted New York for over a decade. Directed by Oscar-nominated filmmaker Liz Garbus (Lost Girls, I’ll Be Gone in the Dark), this three-part docuseries premiered on March 31, 2025, and delves into the systemic failures, police corruption, and relentless advocacy that defined the hunt for one of America’s most elusive serial killers. Here’s why this documentary is a must-watch — and how it reframes the narrative around victims often dismissed by society.
The Gilgo Beach Murders: A Case Shrouded in Neglect
The series opens with the 2010 disappearance of Shannan Gilbert, a 24-year-old sex worker whose frantic 911 call — “they’re trying to kill me” — sparked a search that uncovered 10 sets of remains along Ocean Parkway, including the “Gilgo Four”: Melissa Barthelemy, Megan Waterman, Amber Costello, and Maureen Brainard-Barnes . These women, all marginalized due to their involvement in sex work, became symbols of institutional apathy. For years, their families fought for answers while law enforcement downplayed their disappearances. As Garbus notes, the victims were “daughters, sisters, and mothers” whose lives were reduced to stereotypes .
The documentary highlights how systemic misogyny and bias delayed justice. Suffolk County police initially dismissed Shannan’s case, with officers reportedly laughing off her mother’s pleas: “She’s a prostitute. She’ll turn up” . This indifference persisted even after the Gilgo Four’s remains were found, as authorities failed to follow critical leads, including eyewitness accounts of a hulking suspect driving a green Chevrolet Avalanche — details that later matched accused killer Rex Heuermann .
Police Corruption: The Scandal That Buried the Case
A central theme of Gone Girls is the rampant corruption within Suffolk County’s law enforcement. Former Police Chief James Burke and District Attorney Thomas Spota, both convicted of obstruction of justice, prioritized covering up their own crimes over solving the murders . Burke, who once allegedly referred to the killings as “misdemeanor murders,” blocked FBI involvement and intimidated whistleblowers .
The series reveals how Burke’s reign of intimidation — including assaulting a suspect who stole porn from his car — diverted resources from the Gilgo Beach investigation. It wasn’t until 2022, after Burke and Spota were imprisoned, that a new task force identified Rex Heuermann as a suspect in just six weeks . “The system wasn’t just broken — it was weaponized against these women,” Garbus explains .
Rex Heuermann: The Architect of Terror
In July 2023, Rex Heuermann, a 61-year-old architect from Massapequa, was arrested and charged with seven murders, including the Gilgo Four. The documentary details the evidence that finally linked him to the crimes:
- DNA Match: A hair from a victim matched Heuermann’s DNA, obtained from a discarded pizza crust .
- Vehicle Link: His green Chevrolet Avalanche matched descriptions provided by witnesses years earlier .
- Burner Phones: Surveillance caught him refilling minutes on burner phones tied to the victims .
Despite his arrest, questions linger. Heuermann has not been charged in Shannan Gilbert’s death, and investigators suspect more victims await identification .
A Victim-Centric Approach: Why This Docuseries Stands Out
Gone Girls distinguishes itself by centering the victims’ humanity. Through interviews with families, friends, and surviving sex workers, Garbus reconstructs the women’s lives beyond headlines. Amber Costello’s roommate, Dave Schaller, recounts her final days, describing the “ogre-like” client who stalked her — a chilling foreshadowing of Heuermann’s arrest . Reenactments and personal photos further counter dehumanizing media narratives that reduced the women to “prostitutes” .
The series also critiques societal complicity. As Garbus states, “Their voices had been overlooked for so long because sex workers couldn’t safely report crimes without fear of arrest” . By amplifying these voices, Gone Girls challenges viewers to confront biases that enable predators to target vulnerable populations.
The Legacy of Advocacy: Families Who Refused to Stay Silent
At its core, Gone Girls is a tribute to grassroots activism. Mari Gilbert, Shannan’s mother, became a relentless advocate, pushing for media coverage and pressuring authorities to act. Her efforts not only uncovered the Gilgo Four but also inspired a wave of accountability. “These family members were never going to give up,” Garbus emphasizes .
The documentary serves as a cautionary tale about justice delayed — and a rallying cry for systemic reform. As Suffolk County reckons with its past, the series urges audiences to consider: How many more victims might have been saved if the system had cared?
Conclusion: A Must-Watch for True Crime Enthusiasts
Gone Girls: The Long Island Serial Killer is more than a true crime spectacle; it’s a searing indictment of institutional failure and a moving portrait of resilience. With its meticulous storytelling and unflinching focus on marginalized voices, the series sets a new standard for the genre. Now streaming on Netflix, it’s a haunting reminder that justice, though delayed, can still prevail — but only if we demand it.
