Shannan Gilbert became an unintended hero in the Gilgo Beach murder case after her disappearance in May 2010 inadvertently led police to discover the remains of other women along Ocean Parkway in Long Island. Gilbert, a 24-year-old escort who vanished after visiting a client in the gated Oak Beach community, placed a frantic 911 call claiming someone was trying to kill her. Her disappearance triggered a wide search operation, and although she wasn’t found initially, investigators uncovered the remains of four other women—Melissa Barthelemy, Megan Waterman, Amber Lynn Costello, and Maureen Brainard-Barnes—wrapped in burlap and buried in close proximity. These victims would later be known as the “Gilgo Four.”
While Gilbert herself was not initially considered part of the same series of killings, her case is widely credited with drawing law enforcement’s attention to what would become one of the most infamous serial killer investigations in modern American history. Although police later claimed Gilbert’s death was accidental, her family and supporters rejected that conclusion, believing she was murdered and deserved justice. Her mother, Mari Gilbert, became a fierce advocate for Shannan and the other victims, pushing law enforcement and media to continue investigating the broader pattern of disappearances and murders. In this way, Shannan Gilbert—whose case began as a single missing persons report—unwittingly became the spark that exposed a serial predator stalking women along Long Island’s dark coastal highways.
