The victims of Long Island's real-life serial killer, commonly called the Gilgo Beach Killer, are the focus of Netflix's 2020 film Lost Girls. Starring The Office's Amy Ryan as panic-stricken mother Mari Gilbert, Liz Garbus' film follows Mari's desperate 2010 mission to locate her missing daughter, Shannan.

The frantic search for her daughter leads police to the remains of several missing female sex workers. In real life, the now-late Mari Gilbert was the one who urged the Suffolk County Police Department to investigate whether Shannan's case was connected to the discovered bodies.
