A criminal profile of the Gilgo Beach serial killer

Over the past decade, there have been hundreds of theories about the identity of the Gilgo Beach serial killer (aka the Long Island serial killer). Criminologists, former FBI agents, and amateur detectives have all published their own criminal profiles of “LISK”.

Unfortunately, profiles can be very hit or miss.

The “Coals to Newcastle” study by British policing strategist and former Detective Chief Inspector Gary Copson found that offender profiling is roughly 66% accurate.

As a result, we must never take a profile as fact. Instead, we should view it as a tool that can guide us in the right direction.

We can use a criminal profile to help us narrow in on a suspect, but we should never use it to rule someone out.

In this article, I will scrutinize some of the most common theories about the Gilgo Beach killer. I will also offer some personal insights and theories.

My goal here is to stick to the facts, weed out any assumptions, and present a grounded “profile” of who the killer is without making any large leaps in logic.

Note that I first published this profile on March 7th, 2022. My last revision was in September 2022. In September 2025, I corrected certain grammar mistakes, condensed parts of the text that were too wordy or repetitious, and removed terms that some might consider insensitive. However, I purposely did not modify the logic of the profile. The Wayback Machine archived this page in March 2023, so feel free to confirm.

He does not have to be a member of law enforcement

The theory that the killer is a member of law enforcement is based on three key facts:

  1. He attempted to conceal some of his victims’ identities by dismembering their remains.
  2. Investigators seemingly failed to find any DNA evidence.
  3. He is aware that the police can trace phone calls.

Although this shows us that he understands certain investigative techniques, it does not prove that he is a member of law enforcement. Detective magazines, documentaries, true crime books, movies, and TV shows have all touched on these subjects in the past.

For example, the documentary series “Forensic Files” aired between 1996 and 2011, while the CSI franchise exploded in popularity during the 2000s.

true crime shows

True crime shows, documentaries, and magazines have been popular for decades.

Most people are aware that the police can trace phone calls and match DNA evidence against bodily fluids and hair. Furthermore, there are plenty of examples of offenders dismembering their victims’ bodies.

For example, Ted Bundy decapitated one of his victims in an attempt to hinder her identification.

All in all, we cannot stubbornly cling to the theory that LISK is a police officer. We must accept the fact that the public is aware of common investigative techniques.

The killer knows Gilgo Beach and Manorville

Serial killers tend to operate in comfort zones. Therefore, there is a very good possibility that the killer is familiar with both Gilgo Beach and Manorville.

These are two areas where the authorities discovered more than one victim.

long island serial killer profile

LISK has dumped his victims’ remains at Gilgo Beach and Manorville.

From the offender’s perspective, operating in an unknown area is risky because it introduces too many unknown variables.

Who will be there? How busy is it at certain times? How likely is it that someone will immediately find the body? If someone does show up while I’m there, what should I do? Is there an alternative exit? If I park my car by that entrance, will someone see it? If a local does see my vehicle, will they think it’s suspicious?

These are just some of the thoughts that will be going through the offender’s mind. An unknown area is risky because he won’t have the required knowledge to answer those questions.

As a result, he will usually only operate in familiar places.

Valerie Mack

In November 2000, a group of hunters discovered the torso of Gilgo Beach victim Valerie Mack at a site in Manorville.

Newspaper articles reported that the remains were found near the intersection of Mill Road and Halsey Manor Road.

However, this is inaccurate, as crime scene photographs show that the dump site was actually much further away from the main road.

In other words, he didn’t just dump her torso at the roadside and then drive away.

valerie mack dump site

The red circle illustrates the general area where the killer dumped Mack’s remains. The blue circle highlights the intersection between Mill Road and Halsey Manor. Most online maps erroneously place her remains close to the blue circle. Inset is a Google Street View image of the entrance to the dump site.

In this case, the killer entered a wooded area and drove along a powerline access road.

According to locals, these woods are not the type of place that a stranger to Manorville would choose to drive through, especially if it was late at night.

Notably, Google Map images show that there are no streetlights in the area.

This suggests that the killer has visited this location in the past. For example, he might be a hunter, a hiker, a utility worker, a wildlife enthusiast, or an environmentalist.

In any case, it seems as though this person is familiar with the woods around Manorville and is no stranger to the great outdoors.

Due to the terrain involved, it is likely that “LISK” was driving a van or a truck.

He targets sex workers because they are accessible and vulnerable

Like many serial killers, the Gilgo Beach killer targets sex workers because they are more vulnerable and easier to access than the average woman.

Furthermore, they tend to move around a lot. When a sex worker goes missing, people will often presume that they have gone elsewhere. She might be in and out of rehab due to a drug addiction, or she might regularly switch between red light districts. She might go back to her hometown for periods of time. There might also be other push factors, such as an abusive relationship with a pimp.

Killing sex workers instead of “regular women” also allows him to rationalize his crimes. This makes it easier for him to compartmentalize his “hobby” from the rest of his life.

The Gilgo Beach killer is a sadist

One week after Melissa Barthelemy went missing, an unidentified man started making a series of short and “descriptive” calls to her younger sister, Amanda.

The man in question made these calls from Barthelemy’s phone.

During the conversations, the man toyed with Amanda and taunted her about her older sister’s disappearance. Then, in the final phone call, he said that Barthelemy was dead and that he was going to “watch her rot.”

Melissa Barthelemy

Barthelemy disappeared on July 10th, 2009.

Unfortunately, the authorities were unable to trace the calls, as he purposely made them from crowded areas in Manhattan.

If the caller was indeed the killer, then he may be a sadist who gets gratification by inflicting pain on others.

In this case, he went out of his way and risked exposing himself just so he could psychologically torture the sister of one of his victims.

He did this over a series of seven phone calls.

In other words, he didn’t just risk it once on a whim. Instead, he launched a sustained psychological attack on a 15-year-old girl.

If this individual is a sadist, then those who know him might find him cruel, short-tempered, controlling, intimidating, and demeaning at times. He might also exhibit harmful behavior toward living creatures.

Friends, family, and coworkers may notice that he has a fascination with weapons and violence. He might also come across as cold-hearted and hostile towards people he deems inferior.

There were signs that he tortured them

The phone calls are not the only indication that he is a sadist.

During an interview with Get Secure on The Daily Blu, former Suffolk County Police Commissioner Richard Dormer said that the killer “spent time with the victims.” In a separate interview with the same host, the former SCPD Chief of Detectives, Dominick Varrone, suggested the victims had been tortured.

If the Gilgo Beach killer is a sadist, then it means that he derives pleasure from physical and psychological suffering.

This is the type of man who would have enjoyed witnessing his victims’ terror when he dropped the nice guy routine and they realized that they were in trouble. In fact, he would have relished it so much that he may have actively thought about ways to let his mask slip.

On top of the taunting and psychological abuse, there may have been elements of physical torture.

As you can imagine, this is one of the worst kinds of serial killers to fall victim to. These offenders prefer to prolong the murder. Some of them like to spend hours, or even days, with their victims, depending on how much spare time they have.

He is socially adept and able to manipulate others

In the case of Amber Lynn Costello, he was seemingly able to manipulate his victim into leaving her house without a phone.

According to her roommate, she seemed “familiar” with him. So much so, in fact, that she was willing to suspend her normal rules of operation.

Notably, he offered Amber $1,500 for an overnight stay, a rate that was much higher than usual.

Amber Lynn Costello

Amber Lynn Costello.

Although he may have availed of their services in the past, we cannot be 100% certain of this.

For example, he may have convinced them to suspend their normal rules of operation by simply offering rates that were much higher than normal.

Costello and Maureen Brainard-Barnes were both vulnerable at the time of their murders. Costello had a heavy heroin addiction, while Brainard-Barnes was facing eviction. This may have influenced them to do an out-call with a client they had never met before.

Regardless of whether he hired them before, it is obvious that the victims did not consider him a threat.

Costello did not express any worries about the client to her roommate. Nor did Maureen say anything of note when she called her friend and said that she was meeting a man outside her hotel.

This tells us that he is socially adept and doesn’t come across as strange. He fits in well with society and appears quite normal. This guy isn’t an unhinged weirdo. Instead, he is reasonably normal, calculating, and manipulative. By the time his victims notice any red flags, it is likely already too late.

He seems to strike during the summer months

Most of the victims went missing between June and the start of September:

  • Maureen Brainard-Barnes: July 2007
  • Melissa Barthelemy: July 2009
  • Megan Waterman: June 2010
  • Amber Lynn Costello: September 2nd, 2010
  • Jessica Taylor: July 2003.
  • Valerie Mack: Last seen in the spring or summer of 2000
  • “Peaches” / Jane Doe No. 3: Murdered in June of 1997
  • Fire Island Jane Doe: March or April of 1996

As you can see, his first known victim “Fire Island Jane Doe” is the only woman who disappeared outside of the summer period.

Why does he only seem to strike during the summer?

There are several possible reasons for this:

  1. He is a seasonal visitor to the area. For example, he owns a holiday home in the area.
  2. He lives in the area. However, his family is away during the summer.
  3. The brighter evenings provide him with an alibi to stay out later than usual.
  4. During the summer months, the roadside bushes where he dumps his victims’ remains are thick with leaves. He knows that months will pass before the branches become bare.
  5. Something happens during these months that stresses him out. For example, his workload increases or a family event occurs.
  6. A hobby or activity that provides him with stress relief is not accessible during these months.
  7. He works in an occupation that gives him a lot of free time during the summer.
  8. There is a seasonal aspect to his sexual fantasy.
  9. He might have a designated “kill site” that is “exposed” or inaccessible in the winter. That, or the ruse he employs isn’t as credible during the colder months.
  10. He has an alibi for being in Gilgo Beach during the summer.

As you can see, there are several possible reasons why he only seems to strike during the summer.

Does LISK have access to burlap?

The “Gilgo Four” victims were reportedly wrapped in burlap.

This has led to the theory that the Gilgo Beach killer works in an occupation that provides him with easy access to burlap. That, or he has a hobby that puts him in regular contact with the material.

Although it is possible, it is important to stress that he only needed access to the material once.

burlap lisk

This is an extremely common material with a wide range of uses. Note that the police did not say that the Gilgo Four were dumped in burlap sacks. They said that they were wrapped in burlap.

Manorville has a well-known illegal dumping problem. Therefore, he may have found the material out in the open and decided to keep it.

Burlap is also a common sight on Gilgo Beach, as the fabric is used to combat beach erosion.

Essentially, it would be foolish to rule out suspects based on whether they had regular access to burlap or not. This is a common material that has a wide range of uses.

He does not have to be well educated

A criminal profile in the New York Times opined that the Long Island serial killer is well educated. However, this seems like a leap of logic.

You do not need to have a high level of education to learn about forensic science and police investigative techniques. All you need is access to information and the motivation to absorb it.

In this case, it is likely that the killer has an interest in true crime material. For example, he might watch detective documentaries or read books about serial killers.

It is important to note that he does not need to have extensive knowledge about these subjects to thwart the investigation.

He does not need to know about the intricacies of DNA profiling. All he needs to know is that the authorities can trace hair, bodily fluids, and fingerprints. Similarly, he does not need to be tech-savvy to understand that investigators can trace cellphones. One movie scene where the fugitive removes a SIM card is enough.

There is no evidence to suggest that the Gilgo Beach killer is “high-up”

A sizable number of people are convinced that the killer is a rich or powerful authority figure from the upper echelons of society. However, the evidence does not support this.

It appears as though certain people want to believe this theory because it would make the case more “exciting” or “dramatic.”

Until there is solid evidence to state otherwise, we must presume that he could be from any social class.

He does not have to be intelligent

Serial killers with below-average IQs have successfully evaded law enforcement for lengthy periods of time. For example, Gary Ridgway’s IQ was in the low eighties, and he managed to escape justice for nearly two decades.

In this case, we shouldn’t interpret the killer’s cautious nature as evidence that he is more intelligent than the average person.

In reality, he may just have better impulse control than other killers. This would explain why he is seemingly able to go for lengthy periods of time without killing anyone.

The assumption that serial killers are unable to stop themselves is a myth. In reality, they can find another outlet for their sexual fantasies. For example, the BTK killer, Dennis Rader, was able to substitute the act of killing with various autoerotic activities.

Having said all of that, the Gilgo Beach killer is certainly no dope. The way in which he operates suggests that he is cautious and methodical.

The killer was a regular “john”

In the past, serial killers who primarily targeted sex workers always turned out to be regular clients.

In other words, they frequently hired escorts, many of whom they didn’t harm.

These men were “normal” customers before they started killing, and they often continued to be “normal” customers in between murders.

Some of the women they let live had no idea that their lives were hanging in the balance.

The odds tell us that the Gilgo Beach killer is almost certainly a regular “john”.

This is a man who has spent a considerable amount of time with escorts. He has hired them, talked to them, driven past them, called them, and pored through their online profiles.

Due to his familiarity with the sex industry, his ability to remain dormant for lengthy periods of time, and his psychological need to inflict physical suffering, it is possible he pays sex workers to engage in activities that satiate his urges.

If this is the case, then there is probably at least one sex worker in the Long Island area who remembers a “reliable” and seemingly nonthreatening client who paid extra money for consensual BDSM activities, rough sex, or other unusual requests.

For example, he may have asked her to act out certain violent scenarios, or he may have been into bondage.

The Gilgo Beach killer is a regular client who only kills when he feels that the conditions are right. If he is unable to pick them up without being seen, then he uses their services as normal.

1112 America Avenue

In Amber Costello’s case, LISK parked around the corner from her house in the hope that no one would accompany her to his vehicle. If her roommate did walk her to the car, or a neighbor exited their house, he probably would have called it off or paid for her services as normal. However, that night, it was dark, no one was around, and Costello turned the corner by herself.

LISK is familiar with Manhattan

The killer seems to be pretty familiar with Midtown Manhattan.

Manhattan Long Island serial killer

Click on the image to view the full version.

Four factors suggest that he is no stranger to the area:

  1. His fourth known victim, Jessica Taylor, was last seen working around the Port Authority bus terminal between July 18th and July 22nd, 2003.
  2. Maureen Brainard-Barnes disappeared on July 9th, 2007, after a client picked her up outside a motel on West 46th Street.
  3. In 2009, Melissa Barthelemy’s sister received multiple anonymous phone calls from a man who was in Manhattan.
  4. His third victim, Valerie Mack, reportedly traveled to New York shortly before her disappearance.

This “familiarity” strengthens the theory that LISK is a regular client, as the area around Times Square has had a long-standing reputation for sex work.

The first victim that went missing from Long Island was Megan Waterman, who was picked up outside of the Holiday Inn Express in Hauppauge on June 6th, 2010.

megan waterman

Waterman’s case is the first known instance of LISK picking up a victim on Long Island.

This suggests that Manhattan was his original hunting ground and that he didn’t start picking up sex workers on Long Island until the late 2000s.

If this is true, then it means that the killer is a Long Islander who has been frequenting Manhattan for sex workers since the 1990s. By using Manhattan, he was able to lower his risk of being spotted by a family member, friend, or coworker.

In other words, he was able to put a safe distance between his “hobby” and his home base.

The anonymity of the big city, its reputation for sex workers, and its proximity to Long Island would have made it an alluring destination for him.

In the offender’s mind, there are two conflicting thought processes at play:

  1. “Operating in a distant place is risky, as I don’t know the lay of the land. It also requires far more effort.”
  2. “Operating too close to home requires less effort. However, it is also risky, as there is an increased chance that someone I know will identify me.”

This internal “tug-of-war” may have led him to the Big Apple, which is just a short drive away from Long Island.

His decision to start picking up victims closer to home may have been influenced by his newfound use of Craigslist, which removed the need for him to approach sex workers in red-light districts.

This gave him far more control over the pickup, thereby lowering his exposure.

It is likely that he is a family man

Consider the following:

  1. He appears to have created a “buffer zone” between his “hobby” and his hometown.
  2. He used disposable burner phones, which were an extremely popular tool among married “johns.”
  3. There is a noticeable hiatus between each kill.

It is likely that his behavior as a serial killer was an extension of his behavior as a “john.”

For example, if he picked up his earlier victims in Manhattan, then it means that he likely picked up other escorts there as well.

As I pointed out above, offenders try to stick to familiar places. Therefore, it is likely that he started using Manhattan to pick up sex workers long before he started using it to pick up victims.

In other words, it was his experience of picking up girls there that gave him the confidence to start utilizing it as a hunting ground.

This means that in the period before he started killing, he deliberately chose to put a sizable distance between his “hobby” and his hometown.

This level of caution suggests that he had a lot to lose, such as a girlfriend or wife.

In his mind, picking up sex workers on Long Island was too risky, as there was a higher chance that he would be spotted near a red light district.

Consequently, he drifted towards Manhattan, a large, bustling city where he could get lost among the crowds.

Burner phones.

This theory is strengthened by his use of burner phones, which were a popular tool among married “johns,” so much so that they regularly discussed the topic on anonymous message boards.

When the sex industry moved online, many of these men quickly realized that using their personal phones to contact escorts was far too risky.

As a result, they resorted to using cheap, prepaid phones that they could register with no identification.

This raises the possibility that the Gilgo Beach serial killer initially used burner phones to hide his “hobby” from his wife or girlfriend. It was only later that he felt confident enough to use them to contact targets.

The hiatus between kills

The noticeable hiatus between each victim is an indication that he had other things going on in his life, such as raising children.

This wasn’t an unemployed loser who had a lot of time on his hands. Instead, he was most likely a busy family man who could only get away at certain points.

Remember that this man was most likely a sadist. This, combined with his cautious nature, meant that he preferred to spend a considerable amount of time with his victims. Not just because of his needs but also because he had to clean up and dispose of the remains in a way that didn’t tie back to him.

He couldn’t just kill someone quickly, dump them on the side of a road, and be home in time for dinner. He wasn’t an impulsive creature like Ted Bundy, who was basically an unemployed, functional alcoholic who had a lot of free time on his hands.

The hiatus between kills is most likely a reflection of his time constraints.

Due to work and family life, he only had certain windows of opportunity.

The killer changed his M.O.

The killer went from dismembering his victims and dumping their remains at separate locations to dumping their entire bodies whole at one location on Gilgo Beach.

He also started to target sex workers who were advertising their services on Craigslist instead of women who worked on the street.

This change in M.O. occurred during the murder of Maureen Brainard-Barnes in July of 2007.

Maureen Brainard-Barnes

Brainard-Barnes went missing on July 9th, 2007.

Brainard-Barnes was the first known victim that LISK did not dismember. Additionally, she appears to be the first victim that he targeted via the Internet.

There are a number of possible reasons why he decided to change his M.O.

Jessica Taylor was the first victim whom the authorities were able to identify

In 2003, the authorities identified one of his dismembered victims as 20-year-old Jessica Taylor.

The discovery of Taylor’s identity would have undoubtedly filled him with worry.

Jessica Taylor

Taylor’s torso was found at the end of an access road in Manorville in July 2003.

Now that investigators had a name, there was a chance they could trace her last known movements and identify him.

Between 2004 and 2005, he probably spent a lot of time worrying if the police were going to show up at his door.

All of this served as a wake-up call.

The fact that DNA testing played a role in her identification may have been a reminder that the world was changing. Law enforcement no longer had to rely on dental records or fingerprints.

At the same time, he may have also started to realize that approaching sex workers in public was a risky move. All it would take was one eagle-eyed bystander to turn his entire world upside down.

The Gilgo Beach dumpsites remained undiscovered

By 2007, the Gilgo Beach dump site had gone undisturbed for more than a decade.

As the years passed, his confidence in the area grew.

At some point, he concluded that he no longer needed to dismember his victims and dump their remains at different locations. Instead, he could just wrap their bodies in burlap and throw them into the bushes off Ocean Parkway.

In his mind, dismemberment was no longer worth the hassle.

LISK had far less exposure with the Gilgo Four

The killer’s earlier victims worked on the street. This meant that he had to publicly approach them in red-light districts.

Although he was probably as discreet as he could be, there was always the possibility that someone would remember a victim getting into his vehicle.

This is why he went to such lengths to conceal their identities.

If the police do not know his victim’s identity, then they can’t trace her last known movements, check security footage, and speak to other sex workers who may have been in the area at the time.

With the Gilgo Four, it was different. In the lead-up to their murders, he was able to keep a safe distance by finding them on Craigslist and contacting them using burner phones.

The pickups were far more discreet, and they took place in inconspicuous places.

This significantly lowered his exposure.

Consequently, he may have no longer felt the need to obscure their identities. In his mind, it didn’t matter because the authorities had no way of connecting him to them.

He pays attention to news coverage of his crimes and adapts his M.O. accordingly

In 1996, he put the legs of “Fire Island Jane Doe” in a plastic bag and threw them into the bay. Later, two men spotted the bag after it washed up on a beach on Fire Island.

After this discovery, it appears as though he stopped using the bay.

In 1997, he dumped the torso of an unidentified woman (Peaches) in Hempstead Lake State Park. To identify the woman, the authorities published a photograph of her tattoo in local newspapers.

From that point on, he started mutilating his victims’ tattoos.

Three years later, in 2000, he removed Valerie Mack’s right foot before dumping her torso. The police believe that he did this because she had a tattoo on her ankle.

In 2003, the torso of Jessica Taylor was found in Manorville. In Taylor’s case, the killer attempted to hide a tattoo on her body by cutting it with a knife.

Following Taylor’s identification, he stopped dumping remains out in the open. He also stopped approaching victims on the street.

As you can see, he seemingly adapted his M.O. with each development in the case.

When a Buffalo news station reported on his phone calls to Melissa Barthelemy’s sister, the calls suddenly stopped.

All of this shows us that he actively pays attention to news coverage about his crimes.

If this is true, then it is likely that he frequently Googles the case, its victims, and the officers who are in charge of it. He might even frequent message boards that discuss it. There’s also a very good possibility that he collects news clippings about the murders.

If he is still out there, then it is likely that he found this article before you did.

The Gilgo Beach killer wanted his victims’ torsos to be found

In the cases of “Peaches”, Valerie Mack, and Jessica Taylor, it seems as though the Gilgo Beach serial killer strategically placed their torsos in areas where he knew someone would find them.

peaches lisk

The killer dumped Peaches’ remains just inside this treeline. It was next to a main road and a walking trail.

Although he dumped Valerie Mack’s remains off the beaten track, it was right beside a trail that is popular among hunters.

  • Peaches (1997): A local man finds her torso just a few feet inside the treeline at Hempstead Lake State Park, close to a main road.
  • Valerie Mack (2000): Three pheasant hunters discover her torso near a powerline access road.
  • Jessica Taylor (2003): A dog walker discovered her remains on top of a pile of branches at the end of an access road.

It is telling that he went to great lengths to dismember their bodies and hide their identifying remains, yet seemingly did the opposite when it came to disposing of their torsos.

This suggests that he wanted some form of attention.

For example, he may have enjoyed seeing his crimes on the news or hearing people talking about them. He might have even wanted people to connect the dots between the murders and realize that a serial killer was among them.

Such behavior is incredibly common among serial killers, as it gives them psychological gratification.

It is an added bonus, so to speak.

For example, the Kansas City Strangler, Lorenzo Gilyard, dumped the body of Sheila Ingold in an old van. He then forced the discovery of her remains by pretending to be an innocent passerby who was interested in buying the vehicle. By pretending to be a prospective buyer, he was able to trick the owner into opening the side door and revealing her body.

A sadistic serial killer named Maury Travis was so desperate for media attention that he sent a local newspaper a map that pinpointed the location of one of his victims’ bodies.

Jessica Taylor location

A woman discovered Taylor’s remains at the end of this access road on Halsey Manor Road while she was walking her dog. Notably, he decided to leave her body out in the open. He could have easily dumped the torso inside the treeline, which was just a couple of feet away.

Above, I mentioned that the killer is likely a sadist.

If this is indeed the case, then this kind of behavior should not come as a surprise.

Sadists in particular get a “kick” out of striking fear into the wider community and playing cat-and-mouse games with the authorities.

While speaking about Taylor’s murder, one Manorville resident remarked:

“If you live here and you know the woods, you wouldn’t pull over and leave [a torso] practically on the side of the road. Unless you want it to be found.”

A police spokesperson made a similar statement:

“It doesn’t really seem like [the killer] was concerned that the body would be found. It certainly would not be a place to put a body if you were looking to hide it.”

He may have started conversations about his crimes

If any of the above is true, then it is possible that “the unsub” was eager to initiate conversations about his crimes with others.

Friends and coworkers may have noticed that he was overly enthusiastic about discussing the case.

The belt

The police discovered a belt with initials on it at the Gilgo Four dumpsite. Recently, I opined that the killer purposely placed the belt there as a misdirection.

This may have been his way of continuing his cat-and-mouse games with the authorities at a much lower risk.

Poison ivy

According to a criminal profile published in the New York Times, LISK may have sought hospital treatment for poison ivy.

The profiler likely proposed this theory because the plant is present in the dense thicket beside Ocean Parkway.

megan waterman long island serial killer

The remains of Megan Waterman were discovered in this section of the thicket on Ocean Parkway.

The logic here is that he would have been unable to avoid exposure unless he took certain precautions.

However, it is worth pointing out that poison ivy affects some people more than others. In fact, 25% of people will experience no reaction at all.

For all we know, he experienced mild symptoms that barely fazed him.

If he is familiar with the outdoors, as I believe he is, then it is likely that he understands the saying, “Leaves of three, let it be.”

Internet usage

Some people believe that his use of the Internet to search for victims indicates he is skilled at using computers.

However, this theory ignores the wider societal changes that were taking place during the 2000s.

During the 2000s, Internet usage in the United States increased rapidly. Furthermore, smartphones with Internet access exploded in popularity in the second half of the decade.

Websites such as MySpace, YouTube, and Craigslist were all gaining millions of new users every year.

Between 2000 and 2010, the number of American adults who used the Internet increased from 52% to 76%. This increase was even more pronounced in older age groups.

Such an increase means that the Gilgo Beach killer does not have to be proficient with computers. For all we know, he is someone who merely followed the wider trend.

Profile summary

If there’s one thing that this “profile” should make obvious, it’s that the Gilgo Beach serial killer case is extremely fluid and that there isn’t a lot of publicly available information about the perpetrator.

All we know is that he is adaptable, relatively cautious, and knowledgeable about investigative techniques. He may also be a sadist who is familiar with Manorville, Gilgo Beach, and Midtown Manhattan.

It is likely that this man has used the services of sex workers in the past without causing them any harm. If he is a sadist, then he has probably paid extra for “unusual” requests.

This opens up the possibility that he has a sizable amount of disposable income. However, it does not necessarily mean that he is rich. For instance, he may own a local business or hold a well-paying job.

The location of Valeria Mack’s torso suggests that he is a hunter or someone else who regularly visits the area around the Long Island State Pine Barrens. Judging by the terrain, he might drive a truck or another 4×4 vehicle.

His habit of dumping his victims’ torsos out in the open suggests that he was seeking some form of attention. If this is true, then he probably initiated conversations about the crimes with others.

Judging by the dates that his victims went missing, it seems as though he prefers operating during the summer months. However, we have no idea if this is because of necessity or choice.

Although he did have access to burlap at one point, there is no way to tell if he had regular access to it or not.

His usage of burner phones and his decision to put a buffer zone between his hometown and his “hobby” indicate that he is a family man. The noticeable hiatus between kills reinforces this theory.

Is the Gilgo Beach serial killer still around?

The Gilgo Beach killer’s last confirmed victim went missing in September 2010.

There are four possibilities here:

  1. He is in prison for another crime.
  2. He is dead or seriously ill.
  3. The find at Gilgo Beach spooked him so much that he went dormant.
