Melissa Barthelemy's apartment.

On July 12th, 2009, sex worker Melissa Barthelemy left this house on Underhill Avenue in the Bronx and was never seen again.

Roughly fifteen months later, her remains were found among the bodies of three other sex workers on Gilgo Beach.

Barthelemy is believed to be a victim of the Long Island serial killer (LISK).

On the evening of her disappearance, she traveled to Manhattan to meet a client. According to her friend, she was planning on returning the next morning.

Sadly, that was the last time that anyone saw her alive.

Investigators believe that the 24-year-old took a cab to Manhattan. At that point, she either traveled to Long Island by herself or was picked up by LISK and then driven there.

Cellphone records suggest that Melissa was somewhere on the South Shore of Long Island, as her phone pinged cell towers in Freeport, Massapequa, and Lindenhurst.

Notably, these communities are just across the water from where her skeletal remains were discovered 17 months later.

After murdering Melissa, the Long Island serial killer used her phone to make a series of short and disturbing calls to her younger sister, Amanda.

During these calls, he calmly taunted Amanda in a monotone voice and informed her that her sister was dead. He also stated that he was going to watch her rot.

According to former Suffolk Police Commissioner Richard Dormer, these calls were extremely "descriptive."

The calls continued until a TV station in Buffalo reported on them—a sign that he may have been actively listening out for any news about his victims.

The authorities determined that LISK had made the calls from highly populated areas such as the Port Authority Bus Terminal and Penn Station in Manhattan.

Although the police reportedly attempted to trace his location on four separate occasions, they were thwarted by the short nature of the calls.

Before dialing Amanda's number, the killer made sure that he was hidden among the vast crowds and traffic jams of Midtown Manhattan.

Barthelemy was the first of the "Gilgo Four" to be found.

On December 11th, 2010, canine police officer John Mallia and his cadaver dog "Blue" were walking along a desolate stretch of road on Gilgo Beach when "Blue" suddenly became interested in a specific section of the thicket.

At the time, Mallia was searching for a missing sex worker called Shannan Gilbert, who had gone missing from a gated community on the eastern side of the island six months earlier.

When Mallia entered the thicket to investigate, he stumbled upon a skeleton that had been wrapped in burlap.

Although he initially believed that he had finally found the remains of Shannan Gilbert, this was not the case.

Shortly afterwards, it emerged that the victim was actually Melissa Barthelemy.

This gruesome find triggered a large-scale search of the area.

At that point, the police found the bodies of three other women: Maureen Brainard-Barnes, Megan Waterman, and Amber Lynn Costello.

All of the victims were sex workers who had gone missing between 2007 and 2010. Their killer had seemingly picked them up, murdered them, wrapped them in burlap, and then deposited their remains among the thick brambles and branches beside Ocean Parkway.

1149 Underhill Avenue

Melissa Barthelemy lived in a basement apartment at 1149 Underhill Avenue. She was last seen sitting on the curb outside of this house on July 12th, 2009.

That day, she was planning on meeting an unidentified client for an out-call.

The police believe that she took a taxi into Manhattan before eventually traveling to Long Island.

The 24-year-old grew up in the Kensington neighborhood of Buffalo, New York. In 2006, she moved to New York City after a pimp called Johnny "Blaze" Terry reportedly offered her a job "cutting hair."

It was around this time that she started "turning tricks" around Times Square.

By 2009, she had started to advertise her services almost exclusively on websites such as Craigslist, charging $1,000 for an overnight stay. During this period, she frequently met with clients in bars and hotels on the West Side of Manhattan.

At some point in July of 2009, it seems as though the Long Island serial killer saw one of her online profiles and decided to contact her using a cheap disposable cellphone.

After agreeing to pay $1,000 for an out-call, LISK either picked her up in Manhattan or lured her out to a designated location on Long Island.

Barthelemy's phone was active in Freeport, Massapequa and Lindenhurst.

Freeport, Massapequa, and Lindenhurst

According to the police, Barthelemy's phone was "active" in Freeport, Massapequa, and Lindenhurst. This suggests that she was somewhere on the South Shore of Long Island shortly before her death.

Although the motels in those areas were all investigated, no trace of the missing 24-year-old was ever found.

The Port Authority.

The Port Authority

LISK used Barthelemy's phone to make a series of "descriptive" calls to her younger sister, Amanda.

The fact that he went through great efforts to psychologically torture the teenage sister of one of his victims suggests that he is a sadist who derives pleasure from such activities.

This theory is backed up by comments from LE officials, who said that he "spent time" with his victims and possibly tortured them.

The calls in question were all made from areas near the Port Authority on 8th Avenue and Penn Station on 7th Avenue.

It is likely that he purposely chose these areas because of how busy they are.

Melissa's mother, Lynn Barthelemy, and her stepfather, Jeff Martina, were interviewed in the TV series "The Killing Season."

During the interview, they spoke about the phone calls to Melissa's sister.

When Melissa's phone suddenly started calling Amanda, they initially felt a short wave of relief, as she had been missing for a week.

However, when Amanda answered the call, she heard a man's voice.

During the first call, he reportedly asked the teenager, "Are you a wh*re like your sister? I heard you're a half-breed." In the final call, he stated that he had finally killed her sister and that he was going to "watch her body rot." He then said that he might come and show her one day.

All of the calls were kept relatively short, and he refused to speak to anyone other than Amanda. On one occasion, he immediately hung up when Melissa's mother, Lynn, answered the phone.
