The Long Island serial killer (also referred to as LISK, the Gilgo Beach Killer or the Craigslist Ripper) is an unidentified suspected serial killer who is believed to have murdered 10 to 16 people over a period of nearly 20 years, mostly women who were associated with being sex workers, and left their bodies in areas on the South Shore of Long Island, New York.
The victims were found along the Ocean Parkway, near the remote beach towns of Gilgo and Oak Beach in Suffolk County, and the area of Jones Beach State Park in Nassau County. The remains of four victims were found in December 2010, while six more sets of remains were found in March and April 2011.
On November 29, 2011, the police stated their belief that one person is responsible for all 10 deaths although previously they said it might be the work of multiple suspects.
The attention to the area began when Shannon Gilbert went missing in May 2020 but as of now, despite all efforts by her family, the police claims that she isn’t the victim of the same murderer, rather she just ran into the marshlands.

Identifying Jane Doe #6 – Valerie Mack
Jane Doe #6’s remains were found in two areas of Long Island, more than 40 miles and a decade apart. In 2000 in Manorville they found parts of her body, and in 2011 near Gilgo Beach where they found her head, right foot and hands. The police haven’t released the identity of the victim yet but expected to do so soon.
Her remains aren’t the only ones which were found in two locations – Manorville and Gilgo Beach. Police found the skull of Jessica Taylor, a 20-year-old who disappeared in 2003, near Gilgo Beach and most of the rest of her body in a wooded area of Manorville.
Last year the FBI started to run familiar DNA analysis which led to identifying Jane Doe #6 and also released photographs of a monogrammed belt which can lead to identifying the suspect using the same technic, just as it happened in the case of the Golden State Killer.
The police kept the identity a secret after the announcement, but it’s been revealed that the victim’s name is Valerie Mack. (Pictured below.)
Mack was 24 when she was last seen; she was working as an escort in the Philadelphia area at the time of her disappearance. Family members last saw her in the spring/summer of 2000 near Port Republic, New Jersey. Mack, who also used the name Melissa Taylor, was never reported missing.

Maureen was a struggling mother who worked as a paid escort via Craigslist to pay the mortgage on her house. She had been out of the sex industry for seven months, but she returned to the work in order to pay her bills after receiving an eviction notice. Her body was found in December 2010.

She had been living in the Bronx and working as an escort through Craigslist. On the night she went missing, she met with a client, deposited $900 in her bank account, and attempted to call an old boyfriend, but did not get through.
A week later, and lasting for five weeks, her teenage sister, Amanda, received a series of “vulgar, mocking and insulting” calls from a man, who may have been the killer using Melissa’s cell phone. The calls became increasingly disturbing, and eventually culminated in the caller telling Amanda that Melissa was dead, and that he was going to “watch her rot.”
Police traced some of the calls to Madison Square Garden, midtown Manhattan, and Massapequa, but were unable to determine who was making the calls. Melissa’s mother noted that there were “a lot of calls to Manorville” from Melissa’s phone around the time of her disappearance.

Suspects in the Long Island Serial Killer Case
On December 15, 2016, the attorney for Gilbert’s family said that an escort who had conducted business with former Suffolk County Police Chief James Burke claimed he was connected to the Long Island murders.
In November 2016, Burke had been sentenced to 46 months in federal prison, along with three years of supervised release, for beating a man who stole a duffel bag filled with sex toys and pornography from his vehicle. Gilbert’s attorney said in December that one escort claimed that she had had “rough sex” with Burke during an Oak Beach party and previously saw him dragging someone on the ground during a party.
Burke was reported to have blocked an FBI probe of the LISK case during his time as police chief.
On September 12, 2017, Suffolk County prosecutor Robert Biancavilla said that John Bittrolff, a Suffolk county resident, was a suspect in at least one of the LISK murders. Biancavilla stated that Bittrolff was likely responsible for the deaths of other women, and that there were similarities between the Gilgo Beach crime scenes and Bittrolff’s known murders, for which he was convicted in May 2017 and was sentenced to 25 years for both murders.
Bittrolff was arrested in 2014, linked by DNA found on two prostitute homicide victims, Rita Tangredi and Colleen McNamee, whose bodies were found in 1993 and 1994, respectively.
The Suffolk County police did not comment on the prosecutor’s statement, due to the active homicide investigation of the LISK murders.
Bittrolff was married and had lived in Manorville, three miles from where the torsos of LISK victims Jessica Taylor and “Jane Doe No. 6” were recovered.
The grown daughter of Rita Tangredi, one of Bittrolff’s known victims, was reported to be “best friends” with Melissa Barthelemy, one of the Gilgo Beach victims.Barthelemy’s mother said that her daughter Melissa “had a lot of calls to Manorville from her phone” before her death
Joseph Brewer, an Oak Beach resident, was one of the last people known to have seen Shannan Gilbert alive. He hired her as an escort from Craigslist on the night of her disappearance. Brewer said that shortly after Gilbert arrived at his residence, she began acting erratically and fled into the night. Gilbert was reportedly seen running through Oak Beach, pounding on the doors of homes in Brewer’s neighborhood. Around this time, Gilbert called 9-1-1, saying that “they were trying to kill her”. However, police did not find any evidence of wrongdoing, and Brewer was quickly cleared as a suspect.
Dr. Peter Hackett
Two days after Gilbert’s disappearance, Dr. Peter Hackett, an Oak Beach resident and neighbor of Brewer, called the woman’s mother, Mari Gilbert. He said he was taking care of Gilbert, and that he “ran a home for wayward girls.” Three days later, he called the mother again, denying the phone call or ever being in contact with Gilbert.
The phone calls were confirmed later by the investigators and Gilbert’s remains were found in the marshy area near Hackett’s backyard. Later police revealed that Hackett had a history of inserting himself into, or exaggerating his role in, certain major events. According to records Hackett’s wife and two children were home on the night of Gilbert’s disappearance.
Police later ruled out Hackett as a suspect in the deaths of Gilbert and the LISK victims.
Two days after Shannan Gilbert’s remains were found James Bissett took his own life while in his car at Mattituck park. He ran a nursery which was the main supplier of burlap in the region (some of the victims were found wrapped in burlap)
