The site where Valerie Mack was found.

On the morning of November 19th, 2000, three pheasant hunters discovered the torso of Valerie Mack at this site near Halsey Manor Road in Manorville, New York.

The remains of the 24-year-old sex worker were wrapped in several layers of garbage bags and then dumped in a wooded area beside an access road.

The gruesome discovery was made after the group's hunting dog ventured into the thicket and located the bags.

Valerie's killer dismembered her corpse in an attempt to conceal her identity. By removing Valerie's head and hands, he was able to prevent the authorities from using her dental records or fingerprints to identify her.

This strategy largely worked, as the 24-year-old remained unidentified for more than two decades. During this period, Valerie Mack was referred to as "Manorville Jane Doe" and "Jane Doe No. 6".

The rest of her remains are discovered at Gilgo Beach.

On April 4th, 2011, Valerie's skull, right foot and hands were discovered at Gilgo Beach. Using DNA technology, investigators were able to determine that the remains belonged to the same woman whose torso had been found at this site in Manorville in November of 2000.

Because of her proximity to the other victims at Gilgo Beach, it quickly became clear that "Manorville Jane Doe" had been murdered by the Long Island serial killer.

In this case, LISK had dismembered his victim's remains and then dumped them at two different locations that were 45 miles apart.

Despite finding Manorville Jane Doe's skull at Gilgo Beach, another decade would pass by before the authorities were finally able to identify her.

Manorville Jane Doe is identified as Valerie Mack.

On May 29th, 2020, it was announced that "Manorville Jane Doe" had been identified as missing 24-year-old Valerie Mack from Port Republic in New Jersey.

Investigators uncovered her identify by using genetic genealogy testing, which enabled them to track down her son Benjamin.

Benjamin's DNA had been entered into the system after he was incarcerated for an unstated crime.

Mack was an escort who lost contact with her family in the spring of 2000. Growing up, she spent most of her childhood in the foster system - moving from home to home. As she grew older, she started to develop a drug addiction.

Although Valerie's family attempted to report her missing, the police at the time were under the impression that the young sex worker had left on her own accord.

At the time of her disappearance, Valerie Mack's last known address was in Philadelphia. As a result, her family were shocked to discover that her torso had been discovered 170 miles away at this location in Manorville.

This aerial image shows the general location where three hunters discovered the torso of Valerie Mack. It is approximately 0.6 miles west of Halsey Manor Road.

The site in question sits adjacent to a powerline access road that runs alongside the Peconic River. On maps such as Bing, this access road is called "Hertz Avenue".

Other online maps erroneously place Mack's remains at the southern side of the intersection between Mill Road and Halsey Manor Road. This is because most newspaper articles tend to provide a very general description of the area.

Interestingly, accessing this powerline road does not seem to be a straightforward endeavor. Judging by Google Street View, the main access point for vehicles is a narrow and obscure entrance that leads through a wooded area.

This suggests that the Long Island serial killer has an intimate knowledge of the woods around Manorville.

This theory is further strengthened by the fact that he decided to reuse Halsey Manor Road as a dump site following the murder of Jessica Taylor in 2003.



This "Birds Eye" view shows the access point to "Hertz Avenue".

It is likely that the killer drove his vehicle through this entrance, as carrying human remains for half a mile across an uneven terrain would be physically taxing.

From the killer's perspective, it would also be quite risky. Hauling the body over such a distance would require him to remain in the area for a much longer period of time.

This would undoubtedly increase his exposure.

Other cases have shown us that murderers tend to dump their victim's bodies as quickly as they can. They do not like to stick around at the dump site for too long.

In other words, they like to "get in and get out". This is because they are extremely conscious of the fact that someone might happen across them or their vehicle at any given moment.

This explains why most killers dump their victim's bodies at roadsides.

As you can see, it is relatively obscure and off the beaten track.

It is difficult to imagine someone choosing to drive through this narrow wooded pathway with Valerie Mack's remains in their vehicle unless they knew where it led. Especially if it was dark out.

Google Street View shows that there are no street lights along this stretch of road.

We know from previous cases that serial killers prefer to operate in places where they feel comfortable. This is because operating in an "unknown territory" is risky and unpredictable.

All of this suggests that the Long Island serial killer is someone who is familiar with this area of Manorville.

Judging by the terrain involved, it also stands to reason that he was driving a truck or another 4x4 vehicle. Although the road is accessible by car, it doesn't seem like the best place to drive one.

Note that the southbound pathway is not visible in modern-day aerial images. It is likely that the path has become overgrown or obscured by trees.

The distance between the entrance to the pathway and the main entrance on Halsey Manor Road is exactly 0.6 miles / 1069 yards.
