A murder mystery spanning three decades has finally been solved. What began as a missing persons case in Long Island quickly unraveled into a serial killer investigation when police discovered 10 sets of human remains scattered along the coast, several wrapped in burlap.
Known as The Gilgo Beach Killings, police have described the case as “one of the most consequential homicide investigations” in Long Island history. Prime suspect Rex Heuermann has finally confessed to murders dating back to 1993, bringing the case to a final close.
About the Case
The case began when 23-year-old Shannan Gilbert called 911 in the early morning hours of May 1, 2010, afraid someone was going to kill her. Gilbert, who had been hired as an escort on Long Island, went missing shortly after this phone call.
After conducting a search, investigators discovered remains of four other women near Gilgo Beach, Long Island. Three of them were wrapped in burlap. Identified as Maureen Brainard-Barnes, Amber Costello, Megan Waterman and Melissa Barthelem, the women earned the nickname “The Gilgo Four.”
A larger search in 2011 discovered six more bodies across Long Island, bringing the total to 10 bodies. Police believed this was the act of a serial killer and identified a pattern amongst the victims. Each woman was in their 20s and involved in online escorting.
The remains of Gilbert, the original woman who went missing, were also found in 2011. However, the cause of her death is often debated. Medical examiners ruled it an accidental drowning, but the official autopsy lists the cause of death as “undetermined.”
Gathering Evidence
In 2022, after the case had stalled for over a decade, Suffolk County Police began analyzing evidence. A roommate of one victim told investigators the victim was last seen entering a Chevrolet Avalanche before she went missing.
The roommate also revealed that a person was calling the victim incessantly before she disappeared. Using phone records, police discovered that these calls were coming from a burner phone near Massapequa Park, Long Island.
Police then narrowed down the residents who owned a Chevrolet Avalanche in this small radius. Their prime suspect was Long Island resident Rex Heuermann.
Catching the Culprit
Police began tailing Heuermann and obtained DNA from a pizza box he threw out in Manhattan. The DNA matched male hair found on one of the victims’ bodies.
On July 13, 2023, Heuermann was arrested and charged with the murders of three of the “Gilgo Four.” He pleaded not guilty to every charge.
The following year, he was charged with four more murders. Similar to the original four, these women were also escorts.
Prosecutors revealed in a court hearing that they found a “planning” document on his computer that outlined his strategies for future killings, body disposal tactics and ways to avoid leaving DNA evidence at the scene.
On April 8, 2026, Heuermann pleaded guilty to the seven murders and admitted to an eighth murder that was not previously charged. The murders occurred between 1993 and 2011.
He will be sentenced in June without the possibility of parole.
The Case in the Media
Attracting significant attention over the years, the case has been the subject of many documentaries, films and books.
Most recently, streaming platform Peacock released a three-part documentary series titled “The Gilgo Beach Killer: House of Secrets.” In 2020, Netflix released a film based on the case titled “Lost Girls.” It centered on a woman trying to find her missing daughter, who was one of several escorts killed across Long Island.
After Heuermann was arrested, the director of the film released a new documentary on Netflix titled “Gone Girls: The Long Island Serial Killer.” The documentary examined the case on a deeper level following Heuermann’s arrest and the police’s investigation process.

The following time I read a blog, I hope that it doesnt disappoint me as a lot as this one. I mean, I do know it was my option to learn, but I truly thought youd have one thing fascinating to say. All I hear is a bunch of whining about something that you might repair if you werent too busy in search of attention.
