Logline: When bodies are found along Long Island's pristine beaches, a hunt for a serial killer begins. Rex Heuermann, architect by day, killer by night, just pled guilty to killing eight women. Go inside the investigation that caught the Gilgo Beach Killer.

Extended Logline:

"IMPACT x Nightline: The Monster at the Beach" unravels the decades-long mystery of bodies discovered along the quiet shores of Long Island, where a string of killings shattered the illusion of a peaceful coastal community. As investigators race to connect the victims - many of whom vanished without a trace - the case grows into one of the most haunting serial killer hunts in recent history. Authorities and insiders reveal how advances in technology, relentless police work, and long-overlooked clues ultimately led to Rex Heuermann, an architect whose double life hid in plain sight. Now, after pleading guilty to the murders of eight women, those closest to the case reflect on the victims, the investigation's turning points, and the chilling reality of a predator who evaded capture for years. As the full scope of the crimes comes into focus, one question remains: Is the story of the Gilgo Beach killings truly complete?
