The beach where Fire Island Jane Doe was found
Fire Island, New York, United States
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.
To this day, she remains unidentified.
The location where LISK dumped the body of Peaches
Lakeview, New York, United States
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.
The site where Valerie Mack was found
Manorville, New York, United States
Following the murder of Peaches, LISK seemingly went dormant for three years.
Then, in November of 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, United States
In July of 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.
Understandably, there was a lot of speculation that the two murders were related. However, it wasn't long before the case went cold.
The motel where Maureen Brainard-Barnes was last seen
Manhattan, New York, United States
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, United States
Two years later, on July 12th, 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, United States
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, United States
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 Beach dumpsite
Gilgo Beach, New York, United States
Everything changed in December of 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, wrapped in burlap, and then dumped in the thicket off Ocean Parkway.
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.
Among the remains were the skulls and hands of Valerie Mack and Jessica Taylor, whose torsos had been dumped in Manorville during the early 2000s. This discovery indicated that the Long Island serial killer had been operating in both locations.
The location where Fire Island Jane Doe's skull was found
Massapequa, New York, United States
On April 11th, 2011, the police discovered the skull of an unidentified woman at this site in Massapequa.
DNA testing later revealed that it belonged to the same woman whose legs had washed ashore on Fire Island in 1996.
The site where Peaches' extremities were found
Hempstead, New York, United States
On the exact same day, the police also 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 Peaches, whose torso had been dumped at Hempstead Lake State Park in 1997.
The location where Shannan Gilbert was found
Babylon, New York, United States
In December of 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.
John Bittrolff's house
Manorville, New York, United States
This is the former home of the convicted murderer, John Bittrolff. Notably, it is just three miles away from the location where Mack and Taylor were found.
In 2017, Bittrolff was sentenced to life in prison for the murders of Rita Tangredi and Colleen McNamee, two sex workers who were brutally killed during the early 1990s.
He is also the prime suspect in the murder of Sandra Costilla.
Two months after his conviction, the District Attorney named him as a potential suspect in the Long Island serial killer case.
