The Long Island serial killer's dump site at Gilgo Beach.

This is the location where the Long Island serial killer (LISK) dumped the remains of at least eight of his victims.

It is situated on Jones Beach Island—off Ocean Parkway in Gilgo Beach.

On May 1st, 2010, a sex worker called Shannan Gilbert disappeared after leaving a client's house in Oak Beach.

When a month passed by and there was still no trace of the missing woman, canine police officer John Mallia and his cadaver dog "Blue" were tasked with finding her body.

For more than six months, Mallia and "Blue" persistently searched through fields, swamps, and overgrown terrain.

On December 11th, 2010, Officer Mallia was walking along this stretch of Ocean Parkway when Blue suddenly picked up a scent. 

At that point, the dog led Officer Mallia into the thick brambles by the side of the road, where he uncovered a skeleton that was wrapped in decaying burlap.

Following the discovery, a forensic team was called in to comb the area for evidence. During their investigation of the site, they happened across the remains of three further victims.

Because all four of the victims were wrapped in burlap and dumped in the same location, the authorities quickly realized that they were dealing with a serial killer.

The victims were identified as Maureen Brainard-Barnes (25), Melissa Barthelemy (24), Megan Waterman (22) and Amber Lynn Costello (27). The four women were all sex workers who had previously advertised their services on Craiglist. As a result, the media started to refer to the perpetrator as "the Craigslist Ripper".

In the months that followed, the police widened their search of the area. This led to the discovery of six more victims at multiple sites along Ocean Parkway.

Because all of the victims were found within 4.5 miles of each other, it became apparent that an unidentified killer had been using the area as a dumping ground.

This aerial image pinpoints the four dump sites that were discovered along Ocean Parkway in Gilgo Beach.

As you can see, the offender chose areas that were relatively close to the road. This is consistent with the behavior of other killers.

Carrying a dead body across an uneven terrain that contains thick vegetation would be physically taxing. Furthermore, the perpetrator will typically try to minimize the amount of time that he spends at the site. The longer he stays, the more likely it is that a passerby will spot him or his vehicle.

It is probable that the Long Island serial killer lives relatively close to this location. That or he has visited the area on multiple occasions.

Serial killers typically operate within "comfort zones". These are places that they feel familiar with.

From their perspective, using an unfamiliar area as a dump site is risky because it introduces far too many unknown variables.

The Gilgo Four.

The Gilgo Four

The Gilgo Four were discovered in December of 2010.

Although these were the first victims to be found, they were not the first victims to go missing. In fact, this was his "freshest" burial site.

One of the victims, Amber Lynn Costello, went missing in September of 2010. That was only two months before Officer Mallia and Blue uncovered the first burlap sack.

This means that the Long Island serial killer was using this site just before its discovery.

His decision to dump the remains of four victims in the exact same area seems to be a deviation from his earlier behavior. 

Originally, it seems as though his M.O. was to keep his dump sites apart. By doing this, he could impede any future investigations.

However, in the late 2000s, he had essentially run out of space and could not go further west without increasing his exposure (the median strip narrows and there are houses further down the road).

The Gilgo Four consisted of four women who went missing between 2007 and 2010. All of the victims had been asphyxiated. 

The first victim to be placed at this site was 25-year-old Maureen Brainard-Barnes. She disappeared on July 9th, 2007 after indicating to her friends that she was going to meet a client outside of her motel in New York City.

The second victim to be dumped here was 24-year-old Craigslist escort Melissa Barthelemy, who was last seen on July 12th, 2009. In the weeks following Melissa's disappearance, an unidentified man used her cellphone to make a series of taunting calls to her younger sister Amanda. In one of these calls, the man stated that Melissa was dead and that he was going to "watch her rot".

All of these phone calls were intentionally short and made from crowded areas.

Asian Male.

Asian Male LISK

On April 4th, 2011, police discovered the remains of an unidentified Asian male. He was found just 750 yards east of the Gilgo Four.

Authorities believe that "John Doe" died between 2000 and 2005 and that he may have been transgender. This is because he was wearing women's clothes.

Jessica Taylor.

Jessica Taylor LISK

On March 29th, 2011, investigators discovered a skull, a forearm and two hands in this area off Ocean Parkway. The killer had deposited the remains about 1,100 yards away from the site where the "Asian Male" was found.

DNA analysis proved that the victim was a sex worker named Jessica Taylor, who went missing in July of 2003. Shortly after her disappearance, Jessica's torso was found close to Halsey Manor Road in Manorville, New York.

In this case, it seems as though LISK went to great lengths to try and conceal her identity. Not only did he dismember her and dump her remains in two different places, he also attempted to remove a tattoo from her torso.

Valerie Mack and Baby Doe.

Valerie Mack and Baby Doe

On April 4th, 2011, police discovered the remains of 20-year-old Valerie Mack and an unidentified female toddler at this site near Overlook Beach.

The site in question is about a mile and a half away from the location where Jessica Taylor was dumped.

Valerie and the toddler were found 250 feet apart. However, DNA testing confirmed that they were not related to each other.

Although Valerie Mack's skull, hands, and right foot were all discovered at this site in 2011, her torso was found eleven years earlier - in a wooded area near Halsey Manor Road.

The similarities between the cases of Valeria Mack and Jessica Taylor are striking. The killer dismembered the two women in the early 2000s and dumped their torsos near Halsey Manor Road in Manorville. He then tossed their skulls and hands into the thicket beside Ocean Parkway in Gilgo Beach.

This was most likely done in order to conceal their identities and impede any investigation.

In another twist, DNA testing revealed that the toddler belonged to an unidentified African-American woman called Peaches, whose torso was discovered in Hempstead Lake State Park in June of 1997.

Gilgo Beach.

Gilgo Beach

LISK dumped his victims' remains in the thicket beside Ocean Parkway.

Because the victims were discovered in December of 2010, most photographs of the site show bare brambles and branches.

However, LISK operated during the warmer months. As a result, the roadside thicket on Gilgo Beach would have looked much greener and "thicker" while he was using it.

This would have helped to conceal his victims' remains.

Ocean Parkway.

Ocean Parkway

This section of the road along Ocean Parkway provided him with the "perfect" dumping ground.

Not only is it a straight 1.5-mile stretch, it is also one-way, heading from east to west.

If he dumped his victims' remains at night, then there was almost no chance of another vehicle creeping up on him.

Judging by Google Street View and comments from locals, this area is pretty desolate, especially after dark.

It is likely that LISK checked his rearview mirror for headlights before pulling over to the side.

If there were no lights in the distance, then he had more than enough time to drop off his victim and leave.

Judging by Google Maps, he had roughly 60 seconds to make the drop and then leave before another motorist got too close for comfort.

If another vehicle was too close behind, then it would have taken him less than 10 minutes to circle around and try again.

Median strip.

Median strip

It seems as though he deliberately chose the section of Ocean Parkway where the median strip between the two lanes is at its widest.

There was a 50-meter (55-yard) distance between him and motorists traveling in the opposite direction. The strip also contained trees and shrubbery.

If his headlights were off, it would have been extremely difficult to see him or his vehicle, as there were no streetlights in the area.

The median strip narrows to 6 meters if you drive slightly west of this location. This might explain why he decided to place the Gilgo Four in one area. In other words, he ran out of space. If he had continued any further, he would have increased his risk by exposing himself to oncoming traffic.


LISK Gilgo Beach

If you compare the locations with the dates that the victims went missing, a pattern seems to emerge.

Here, you can see that he started on the eastern side of the island and then worked his way west, spacing out his victims along the way.

However, by the late 2000s, he was hesitant to continue any further. The narrowing of the median strip and the presence of houses left him with no other option but to stick with the one stretch of road that he felt comfortable with.

This "pattern" is also interesting because it suggests that the unidentified victim, "Asian Male", probably went missing between 2004 and 2006 (the police believe that he was murdered at some point between 2000 and 2005).

From what we know, there is only one example of the Long Island serial killer striking more than once in the same year (Waterman and Costello in 2010, at the very end of his spree).

If this east-to-west pattern isn't a coincidence and he was deliberately trying to "space out" his dump sites, then it would mean that "Asian Male" (John Doe) disappeared at some point between the murders of Jessica Taylor (2003) and Maureen Brainard-Barnes (2007).

He couldn't progress further west.

Gilgo Beach

This west-facing aerial image illustrates why the killer was hesitant to progress further west.

As you can see, the median strip on Ocean Parkway narrows. This would have exposed him to traffic heading eastward. There were also a number of residential properties up ahead.
