New Information On Gilgo Beach Victims Released: PD

GILGO BEACH, NY — Suffolk County Police have released new information on four Gilgo Beach homicide victims.

On Thursday, Commissioner Rodney K. Harrison announced previously unreleased information regarding Maureen Brainard Barnes, Melissa Barthelemy, Megan Waterman and Amber Lynn Costello.

Known as the "Gilgo Four", the victims were located within a quarter mile of one another near Gilgo Beach in December, 2010.

“As the homicide squad continues its tireless work on this investigation, we believe now is the right time to disseminate this previously unreleased information in hopes of eliciting tips from the public and providing greater transparency about the victims,” Harrison said.

Last month, police also released surveillance video of victim Megan Waterman, as she checked into a Hauppauge hotel between June 4, 2010 and June 6, 2010.

“Through our recent partnership with Crime Stoppers increasing the reward in this case to $50,000, our hope is that the public will review this information and come forward with any additional tips about the victims or a potential suspect or suspects,” said Harrison.

The newly released information can be found below and has also been updated on the Gilgo News website:

Maureen Brainard-Barnes

Maureen Brainard-Barnes was 25 years old when she went missing and was living at 180 Prospect St. in Norwich, Connecticut. She is believed to have taken an Amtrak train from New London, CT to Grand Central Terminal in Manhattan on July 6, 2007.

While in Manhattan, she was staying at the Super 8 Motel, located at 59 West 46th St. At the time, Brainard-Barnes, who was 4-feet, 11 inches tall, was working as a sex worker, advertising on Craigslist, Backpage and other websites, police said. She was known to advertise under the names Juliana or Marie. Her routine was to travel to Manhattan for a few days to work as an escort, and then return home to Connecticut, authorities said. While in Manhattan, she was known to stay at The Super 8, The Red Roof Inn on West 32nd Street, the Carter Hotel on West 43rd St. and the Manhattan Hotel on 8th Avenue.

On occasion, Brainard-Barnes would travel with another female who worked out of a different room at the same location, police said. They both may have used a male friend, who they would refer to as their cousin, to accompany them and offer a level of safety and protection. Brainard-Barnes traveled with her female friend the weekend she went missing, however her friend returned home early and Brainard-Barnes stayed behind, officials said. Brainard-Barnes was last heard from on July 9, 2007 at 11:43 p.m. when she called a friend in Connecticut, police said. Although she was known to work out of motel rooms, on the night of July 9, 2007, she told her friend she would be going to meet someone outside of the motel on an “out-call," authorities added.

Brainard-Barnes was reported missing by a friend to the Norwich Police Department on July 14, 2007, police said. The NYPD assisted the Norwich Police Department in the missing person investigation, eventually taking it over. Brainard-Barnes was found on December 13, 2010 on the north side of Ocean Parkway, near Gilgo Beach, during the search for Shannan Gilbert, who had gone missing from Oak Beach, police said.

She is believed to be the first victim in what is known as the “Gilgo Four.”

Melissa Barthelemy

Melissa Barthelemy was last seen at her residence, a basement apartment at 1149 Underhill Ave, police said, in the Unionport section of the Bronx, on July 12, 2009. She was 4-feet, 1- inches tall and was 24 years old when she was last seen.

Barthelemy was a sex worker who advertised on Adult Friend Finder as well as other sites. She used the aliases Chloe and VerySexyChloe, police said. She had tattoos of the words “Blaze” and “Focus” on her back, and letters on her chest. She was also known to meet clients at bars, restaurants and hotels on the West Side of Manhattan.

On July 12, 2009, the night she was last seen, Barthelemy told a friend she was going to see a man and would be back in the morning. This friend was aware she was a sex worker, but Barthelemy offered no other details. Her cellphone records show she traveled from the Bronx to Manhattan, most likely via taxi, police said.

Barthelemy’s mother had not heard from her or been able to contact her for a few days so she reported her missing to the NYPD on July 18, 2009, police said. The investigation showed cellphone activity in Manhattan, Freeport, Massapequa and Lindenhurst. Motels in and near these neighborhoods were investigated.

After Barthelemy had been reported missing, her younger sister received a series of "taunting" phone calls from someone using Barthelemy’s phone. These calls are believed to have come from the killer and were made from the area near the Port Authority Bus Terminal on 8th Avenue, and also from near Penn Station. These areas were thoroughly canvassed immediately following the calls, however, due to the large amount of pedestrian and vehicular traffic, no leads were developed, police said.

On December 11, 2010, Barthelemy’s body was found on the north side of Ocean Parkway, near Gilgo Beach, during the search for Shannan Gilbert, police said.

Although she was the first victim found, she is believed to be the second of the "Gilgo Four" to be killed, police said.

Megan Waterman

Megan Waterman was 22 when she was last seen on June 6, 2010, police said. Waterman was a resident of Scarborough, Maine and was a sex worker who advertised on Craigslist and Backpage. She used the names Lexxy and Sexy Lexi. She was last seen by her family boarding a New York-bound Concord Trailways bus in Maine, possibly with her pimp, authorities said.

Waterman was staying at the Holiday Inn Express, located at 2050 Express Drive South in Hauppauge. Waterman was known to stay at other hotels and motels on Long Island, including the Extended Stay America in Bethpage. Waterman left the Holiday Inn Express at 1:30 a.m. on June 6, 2010 to meet a client. Waterman called her pimp, who was in Brooklyn at the time, to tell him she was going to a convenience store near the hotel, police said.

Waterman was reported missing to the Scarborough Maine Police Department on June 8, 2010, police said. Family members felt it was unlike her not to call them to check on her then-3-year-old daughter. The Scarborough Maine Police Department contacted the Suffolk County Police to assist in the missing person investigation.

Waterman’s body was found on December 13, 2010 on the north side of Ocean Parkway, near Gilgo Beach, during the search for missing person Shannan Gilbert, police said.

She is believed to be the third victim in what is known as the “Gilgo Four.”

Waterman’s pimp was arrested on federal charges of interstate trafficking of prostitutes on April 11, 2012 and was sentenced to three years in federal prison in January, 2013, police said. There is no information to suggest he had any knowledge or participated in any way in Waterman's murder, police said.

Amber Lynn Costello

Amber Lynn Costello was 27 and lived at 1112 America Ave. in West Babylon when she was last seen by acquaintances. Costello was a heroin addict who lived at the house with another female and two men, who were also heroin addicts, police said. Costello, who was 4-feet, 11-inches tall, and was a sex worker who advertised on Craigslist and Backpage to support her and her roommates’ heroin addiction, authorities said. Costello used the names Carolina or Mia and had tattoos of “Kaos” on her neck, a butterfly on her lower back and the word “Margeret” on her leg, police said.

Costello had moved to New York from Clearwater, Florida and had completed a 28-day drug rehab, but had relapsed not long before her disappearance, police said.

Costello and her roommates shared a cellphone. The other female roommate was also a sex worker supporting a heroin addiction and the two male roommates would arrange dates with clients for the women, authorities said. Costello did “in-calls” at her home, as well as “out-calls.”

When Costello would meet clients at her home, the two male roommates would often arrange a scam, during which, once a client had paid money, and before any sex acts occurred, they would confront the client saying Costello was their girlfriend and the client would flee, police said.

Costello was last seen leaving her residence on foot on September 2, 2010 to meet a client who was picking her up at her house, police said. Costello did not have her cellphone with her at the time and she was never reported missing, police said.

Costello was found on December 13, 2010 on the north side of Ocean Parkway, near Gilgo Beach, during the search for missing person Shannan Gilbert, police said.

She is believed to be the fourth victim in what is known as the “Gilgo Four.”

Audio recordings of a 911 call made by victim Shannan Gilbert are also to be released, police announced last month.

Gilbert's remains were found in 2011 in Oak Beach. She was a New Jersey escort who disappeared 10 years ago after meeting a client for sex on Oak Beach, leading to the discoveries of the 10 sets of human remains.

The search for Gilbert first led to the bodies of four other prostitutes, all of whom were strangled and stuffed in burlap bags. A total of 11 sets of human remains, including Gilbert's, were found along Ocean Parkway. Police have been searching for a serial killer ever since.

Mari Gilbert, Shannan's mother, was later murdered by another daughter.

A Netflix movie, "Lost Girls," was made about the case; the movie was filmed on the North Fork in 2018.
