48 Hours “The Killing of Theresa Fusco” April 25 2026 Preview

CBS’s 48 Hours presents a powerful new episode titled The Killing of Theresa Fusco, airing Saturday, April 25, 2026, at 10:00 PM ET/PT. Correspondent Erin Moriarty reports on a decades-old Long Island mystery that finally sees movement after nearly 41 years, offering long-awaited answers to families who never stopped searching.

The case dates back to 1984, when a series of disappearances shook a quiet Long Island community. Fifteen-year-old Kelly Morrissey vanished first, followed months later by her friend Theresa Fusco, who disappeared after leaving her job at a local roller rink. Not long after, 19-year-old Jackie Martarella also went missing. The cases remained unsolved for decades, leaving families in a painful state of uncertainty.

In Theresa Fusco’s case, a breakthrough finally came through modern forensic technology. Investigators were able to extract DNA from a seemingly ordinary item, a discarded smoothie straw, which helped identify a suspect and breathe new life into the investigation. The development marked a turning point in a case that had long gone cold.

The episode features interviews with Theresa’s father Thomas Fusco and her brother John Fusco, along with friends and family members of the other victims. Their accounts reflect the lasting impact of the disappearances and the emotional weight carried for decades. Law enforcement officials, including former detectives and prosecutors, explain how advancements in DNA analysis made it possible to revisit the evidence and pursue justice.

The Killing of Theresa Fusco explores the persistence of investigators and families, and how one small piece of evidence can unlock the truth after decades. The episode airs Saturday night on CBS, with streaming available on Paramount+.
