True crime specialist Peninsula Television has delivered a gripping new 3 x 60’ documentary series for Sky Crime, exploring one of the most notorious serial killer cases in recent American history.

Commissioned by Sky Crime, Terror on Long Island examines the investigation into the Long Island serial killings, a case that shocked communities and remained unsolved for more than a decade. Beginning with the disappearance of Shannan Gilbert in 2010, the series traces how the search for a missing woman led to the discovery of multiple victims along Gilgo Beach, exposing a chilling pattern of violence. Through exclusive interviews with investigators, forensic experts and the victims’ families, the series explores the challenges, controversies and breakthroughs that shaped the investigation.

Culminating in 2026 with the sentencing of Rex Heuermann, Terror on Long Island reveals how advances in forensic technology and years of determined investigative work brought renewed hope for justice while giving voice to the victims and those who never stopped seeking answers.

David Harvey, Executive Producer of Terror on Long Island, said, “This series delivers a gripping, immersive look at a case that captured global attention. Featuring unexpected twists and compelling investigative storytelling, Terror on Long Island is set to be essential viewing for true crime audiences.”
