The Gilgo Beach serial killings were a series of murders on Long Island, New York, between 1993 and 2010. The case gained national attention in late 2010 and 2011, when police searching for missing woman Shannan Gilbert discovered the remains of ten victims along Ocean Parkway near Gilgo Beach and in nearby areas of Suffolk and Nassau counties. Four victims—Melissa Barthelemy, Maureen Brainard‑Barnes, Megan Waterman, and Amber Lynn Costello—were found in December 2010 in close proximity and became known as the "Gilgo Four." Six additional sets of remains were located in March and April 2011, several of which were later connected to earlier unsolved cases.
