The beach where Karen Vergata was found
Fire Island, New York
On April 20th, 1996, two men discovered a woman's severed legs floating in the water by Blue Point Beach on Fire Island.
Although nobody knew it at the time, this was the first sign of the existence of the Long Island serial killer.
The victim remained unidentified for 26 years, during which she was known as Fire Island Jane Doe.
She finally got her name back in August 2023, when the authorities publicly announced that she had been identified as Karen Vergata.
The location where Tanya Denise Jackson was found
Lakeview, New York
Roughly fourteen months later, on June 28th, 1997, the torso of an unidentified woman was discovered next to a trail at Hempstead Lake State Park.
She was nicknamed "Peaches Jane Doe" due to a tattoo of a peach that she had on her chest.
In April 2025, she was identified as 26-year-old Tanya Denise Jackson.
The site where Valerie Mack was found
Manorville, New York
Following the murder of Peaches, LISK seemingly went dormant for three years.
Then, in November 2000, three hunters discovered the torso of Valerie Mack at this site near Halsey Manor Road in Manorville.
The site where Jessica Taylor was found
Manorville, New York
In July 2003, he placed Jessica Taylor's torso at the end of this access road in Manorville.
The 20-year-old was found just half a mile away from the wooded area where Mack's remains had been discovered three years prior.
Although there was speculation that the two murders were related, it wasn't long before the case went cold.
The motel where Maureen Brainard-Barnes was last seen
Manhattan, New York
The Long Island serial killer struck again following a four-year hiatus. However, by this stage, he had changed his M.O.
Instead of picking up girls off the street, he began contacting escorts on Craigslist using a burner phone.
On the night of July 9th, 2007, Maureen Brainard-Barnes left this motel in Midtown Manhattan to meet a client for an outcall and was never seen again.
Notably, Brainard-Barnes was the first of the Gilgo Four to go missing.
Melissa Barthelemy's apartment
The Bronx, New York
Two years later, on July 10th, 2009, sex worker Melissa Barthelemy disappeared after she left this house on Underhill Avenue in the Bronx.
The police believe that she took a taxi to Manhattan to meet a client.
Later that night, her phone pinged off a number of cell towers on the South Shore of Long Island.
The hotel where Megan Waterman was last seen
Hauppauge, New York
Roughly one year after Barthelemy's disappearance, a sex worker named Megan Waterman left this hotel in Hauppauge to meet a client and never returned.
Surveillance footage from the early hours of June 6th, 2010, showed her walking out of the lobby and turning to her right.
Amber Lynn Costello's house
West Babylon, New York
On September 2nd, 2010, Amber Lynn Costello vanished after a client picked her up outside this house in West Babylon.
The client in question had offered her $1,500 for an overnight outcall.
Although Costello was the fourth victim to go missing in three years, nobody had connected the dots between their disappearances.
Furthermore, the media had long forgotten about the murders of "Fire Island Jane Doe", Peaches, Valerie Mack, and Jessica Taylor.
The Gilgo Four dumpsite
Gilgo Beach, New York
Everything changed in December 2010, when the police discovered the remains of Brainard-Barnes, Barthelemy, Waterman, and Costello at this location near Gilgo Beach.
The four women had been asphyxiated and dumped in the thicket off Ocean Parkway. Three of the remains were wrapped in duck-blind camouflage burlap.
The discovery of the "Gilgo Four" made it painfully obvious that an unidentified serial killer had been operating on Long Island for quite some time.
In the months that followed, the authorities broadened their search and discovered the remains of six more victims.
The site where Jessica Taylor's identifying remains were found
Gilgo Beach, New York
On March 29th, 2011, the police discovered a woman's skull, hands, and forearm at this section of Ocean Parkway near Gilgo Beach.
DNA testing proved that the remains belonged to Jessica Taylor, whose torso had been dumped in Manorville eight years earlier.
This discovery was significant, as it indicated that the Long Island serial killer had been operating in both Manorville and Jones Beach Island.
The site where Asian Doe was found
Gilgo Beach, New York
On April 4th, 2011, the skeleton of a young Asian male was discovered roughly 0.3 miles east of the Gilgo Four.
The victim remains unidentified to this day.
The site where Valerie Mack and Tatiana Dykes were found
Gilgo Beach, New York
On April 4th, 2011, a police search team discovered two sets of human remains at this section of Ocean Parkway near Gilgo Beach.
The first set included the skull, hands, and foot of Valerie Mack, whose torso was discovered in Manorville in November 2001.
The second was the skeleton of a female toddler called "Baby Doe", who was later determined to be the daughter of Peaches. In April 2025, Baby Doe was publicly identified as two-year-old Tatiana Dykes.
The location where Karen Vergata's skull was found
Massapequa, New York
On April 11th, 2011, the police discovered the skull of an unidentified woman at this site near Tobay Beach.
DNA testing later proved that it belonged to the same woman whose legs had washed ashore on Fire Island in 1996.
In 2023, the authorities revealed that the victim had been identified as Karen Vergata.
The site where Tanya Jackson's extremities were found
Hempstead, New York
On April 11th, 2011, the police discovered the arms and legs of a female at this site in Jones Beach State Park.
DNA tests later confirmed that the remains belonged to Tanya Jackson, whose torso had been dumped at Hempstead Lake State Park in 1997.
The location where Shannan Gilbert was found
Babylon, New York
In December 2011, the remains of missing sex worker Shannan Gilbert were found in this marsh near Oak Beach on Jones Beach Island.
Although her disappearance eventually led to the discovery of the Gilgo Four, neither the SCPD nor the FBI believe that she was a victim of the Long Island serial killer.
Rex Heuermann's house
Massapequa Park, New York
In July 2023, the police arrested an architect named Rex Heuermann at this house in Massapequa Park.
The 59-year-old is currently the prime suspect in the case.
The street where Heuermann was arrested
Manhattan, New York
On the evening of July 13th, 2023, Heuermann was arrested near the corner of 5th Avenue and 35th Street in Manhattan—just 100 feet from his workplace.
The following day, he was charged with three of the murders.
The woods where Sandra Costilla was found murdered
Southampton, New York
On November 21st, 1993, two hunters discovered the remains of Sandra Costilla at this location in North Sea, Southampton. The 28-year-old had been strangled to death.
Initially, the authorities presumed that a local carpenter and convicted murderer named John Bittrolff was responsible. However, in June 2024, Rex Heuermann was indicted for the killing.
Rex Heuermann's storage unit
Amityville, New York
Following his arrest, the authorities raided a storage unit that Heuermann had been renting at Omega Self Storage on Sunrise Highway.
During the search, investigators found thousands of documents.
One of the documents was a Bank of America credit card statement from July 2007, which proved that his wife and children had been out of town when Maureen Brainard-Barnes went missing.
Tanya Denise Jackson's apartment
Brooklyn, New York
In April 2025, the Nassau County Police Department announced that it had identified "Peaches" and "Baby Doe" as Tanya Denise Jackson (26) and her two-year-old daughter, Tatiana Dykes.
They also stated that she was living in an apartment at 230 54th Street in Brooklyn, New York, in 1997—the same year as her murder.
