gilgo beach long island serial killer remains

Between 2010 and 2011, investigators discovered the remains of nearly a dozen individuals off Ocean Parkway in Long Island, New York. Four of the identified victims were sex workers who advertised themselves on Craigslist. They were all strangled and wrapped in burlap sacks before being dumped near Gilgo Beach. All four women were reported missing between 2007 and 2010. It was clear that this was the work of one man. The media dubbed him the Long Island Serial Killer.

There were six other sets of remains that were found months later and within five miles of the four victims pictured above. They included four women, a man and a toddler. The young male was later determined to be of Asian decent and was wearing female clothing at the time of his death. He died from blunt force trauma. DNA tests revealed that one of the female victims was the mother of the toddler whose remains were also discovered. Investigators believe the remains had been there between 5 – 15 years at the time of discovery.

Police believe all 10 victims are linked to the same killer, who may have been killing in the area for nearly 20 years.

So, Who Is the Long Island Serial Killer?

FBI profilers and criminologist have tried to put together a profile of the killer based off what little evidence they have. Here is what they believe:

  • He is a white male in his mid-30s to mid-40s.
  • He has a reliable job and may own a large car or truck.
  • He may be married or have a girlfriend.
  • He may be charming with great social skills (this assumption is based off the evidence that the women felt comfortable enough to meet the killer on his terms).
  • He is an organized killer with possible knowledge of police work or forensic techniques. He may have even worked in law enforcement.
  • He lives or used to live on or near Ocean Parkway on the South Shore of Long Island.
  • The four identified victims were reported missing between Memorial Day and Labor Day. This could mean that there is a seasonal nature to the killer’s connection to the area. For example, it may be the time when his wife or children are away for the summer.
  • After the disappearance of Melissa Barthelemy, her sister received a series of vulgar, mocking calls from an unidentified male using Melissa’s cell phone. Police believe the calls came from Manhattan. The killer may work or live in the area.
