After 23-year-old escort Shannan Gilbert disappeared in 2010, police stumbled upon a serial killer's graveyard in Gilgo Beach, Long Island — which held the human remains of four other missing sex workers. Shortly after, authorities discovered six more bodies along the same stretch of road. "Truth and Lies: The Hunted" chronicles the twists and turns in the decade-long investigation to find the Long Island serial killer, uncovering allegations of corruption and police biases that slowed the investigation and enraged the victims' family members. This episode takes viewers inside the task force that used new technology that led to the July 2023 arrest of the man now accused of murdering those four sex workers: Rex Heuermann, a husband and father who police claim was leading a dark double life. Heuermann has pleaded not guilty to these charges. "Truth and Lies: The Hunted" explores the police's ongoing investigation of this notorious case.
