The Long Island Serial Killer case - also known as the Gilgo Beach murders - is back in the spotlight. We’ve learned that Rex Heuermann, accused of seven murders, is expected to plead guilty to these grisly crimes on April 8th, 2026. What began 16 years ago with a missing woman in Long Island, New York led investigators to a chilling discovery along Ocean Parkway: the skeletal remains of multiple women, many of them sex workers, in what would become one of the most disturbing serial killer cases in recent true crime history. 

For years, the suspect known as LISK remained unidentified - until 2023, when police arrested an architect, husband, and father accused of nearly unthinkable acts of violence.

Now, with a potential guilty plea looming, Senior Investigative Reporter Anne Emerson revisits how the Gilgo Beach killings were first uncovered. Joined by Investigative Reporter Kristin Thorne who has covered the case since the initial discoveries, part one of this interview breaks down the origins of the Long Island Serial Killer investigation and what could come next in this shocking case.
