Amber Lynn Costello's house.

This is the house where sex worker Amber Lynn Costello was last seen.

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

On September 2nd, 2010, the 27-year-old received a number of phone calls from a client who was willing to pay $1,500 for an overnight outcall.

Notably, this figure was much higher than the usual rate.

Unbeknownst to her, the man in question was using a cheap disposable burner phone that couldn't be traced back to him.

At around 10.30 p.m., Amber left this small house in West Babylon and was never seen again.

Three months later, the remains of Amber and three other sex workers were discovered at the Long Island serial killer's dump site on Gilgo Beach.

The four women had been asphyxiated, wrapped in burlap and then dumped in the thicket beside Ocean Parkway.

At the time of her disappearance, Amber was living at this house with her roommate, Dave Schaller. Both Amber and Dave were heroin addicts.

That day, Costello used her roommate's phone to negotiate a price with a client. According to Dave, she seemed to be familiar with the man. So much so, in fact, that she was willing to drop all of her normal precautions.

For safety reasons, most escorts are unwilling to do overnight stays with men that they have never met before.

Although this might suggest that LISK was a previous client, we also can't rule out the possibility that she decided to risk it.

Amber was desperate for money because of her drug addiction. At the time, she was reportedly going through multiple bags of heroin per day.

As a result, the promise of such an unusually high fee might have been far too tempting for her to turn down.

Notably, the killer did not park outside of her house. Furthermore, when Amber told him that she did not have a phone, he assured her that she could use his one.

Sadly, she had no way of knowing that the voice on the other side of the line belonged to a serial killer who had been successfully luring sex workers into his web since the 1990s.

Shortly after 10.30 p.m., she exited this house on America Avenue and turned right. According to Dave, the killer's car was just around the corner, at a crossroads that is visible from the front porch.

By parking at this location, LISK was able to hide his vehicle from Amber's roommate and anyone else that might have been inside her house.

The following morning, Dave started to worry because his roommate was still gone.

Fearing that something might have happened to her, he decided to raise the alarm with her sister, Kimberly Overstreet.

Unfortunately, Kimberly did not file a missing persons report. In her opinion, her sister was probably off getting high with someone else.

Because Amber was a drug addict and a sex worker, she did not believe that the police would take her sister's case seriously.

Three months later, on December 13th, 2010, investigators found her remains wrapped in burlap on Gilgo Beach.

Dave Schaller

Amber Costello and Dave Schaller lived at this 753 sq ft house on America Avenue in West Babylon, Long Island.

At the time, they were both drug addicts. According to Kimberly Overstreet, her sister was a heavy heroin user who went through 10 bags per day.

When the 27-year-old's remains were discovered on Gilgo Beach, Dave was able to identify her body after seeing a small tattoo on her arm.

The Long Island serial killer picked Amber up on Hampton Road.

This aerial image shows the location where the Long Island serial killer picked up Amber Costello. Note that this image is facing south.

On September 2nd, 2010, LISK parked his vehicle on Hampton Road, which is just around the corner from Amber's house.

Because it was just after 10.30 p.m., it was dark out. By that stage, most residents would have been settled in for the night.

Once LISK was parked up, he called Amber using an untraceable burner phone and told her that he was outside, just around the block.

Judging by Dave Schaller's account, she seemingly trusted this man enough to drop all of her normal rules of operation. This raises the possibility that he was a former client.

However, we also can't ignore the fact that Amber was heavily addicted to heroin. When you consider the large sum of money that was being offered, it's easy to see why she might have decided to risk it.

LISK erred on the side of caution by parking out of view of the house. That way, he could prevent her roommate (and any other occupants inside the house) from getting a good look at his vehicle.

While he was waiting, it is likely that he remained vigilant. He would have been checking his mirrors and paying close attention to nearby properties.

If Dave had accompanied Amber to the corner that night, it is extremely likely that the killer would have spotted him. At that point, he would have used Amber's services as normal.

It is the author's opinion that LISK's vehicle was facing south at the time. That way, he could continue on south and avoid exposing his vehicle at the crossroads.

This aerial photograph of America Avenue was taken on April 1st, 2010, roughly five months before Amber disappeared. We have circled the house in red.

According to her roommate, she walked east along America Avenue until she came to the crossroads. At that point, she looked up and down Hampton Road before turning right.

Hampton Road

That night, LISK parked his vehicle on Hampton Road.

Once he was confident that he had picked up Amber Costello without being seen, it is likely that he drove southbound. At that point, he either circled around the block and headed north or he continued towards Sunrise Highway.

It is important to note that the killer's decision to park away from the house wasn't overly suspicious. This is because Dave didn't like clients pulling up in front of their residence.

In other words, he didn't want their neighbors to realize that Amber was working in the sex trade.

Therefore, it is possible that she specifically told him not to park in front of the house.
