The Gilgo Beach serial killings were part of a series of murders spanning from the early s until Many of the victims' remains were found over a period of months in and during a police search of the area along Ocean Parkway , a road near the remote beach town of Gilgo on Long Island in Suffolk County, New York.
The search was prompted by the disappearance of Shannan Gilbert, who, like many of the known victims, worked as an escort and advertised on Craigslist. The remains of four victims designated "The Gilgo Four" were found within a quarter of a mile of each other near Gilgo Beach in December Six more sets of remains were found in March and April in Suffolk and Nassau counties.
Authorities believe Gilbert became lost in the marsh land and died either from exposure or accidental drowning.
In July , Rex Andrew Heuermann, a year-old Nassau County resident, was arrested in Midtown Manhattan and subsequently charged with three counts of first-degree murder, as well as three counts of the lesser charge of second-degree murder, related to the deaths of Melissa Barthelemy, Megan Waterman, and Amber Costello. Costilla's murder had not previously been linked to the Gilgo Beach serial killings. Heuermann has pleaded not guilty on all counts. Heuermann is an architect and has lived much of his life in Massapequa Park on the south shore of Long Island.
In an interview on YouTube, Heuermann stated he has worked in Manhattan since Court records also indicated that he had searched the internet for "sadistic materials, child pornography, [and] images of the victims and their relatives.
