DNA Breakthrough Solves 1984 Long Island Teen Murder Case

Nearly 41 years after Theresa Fusco vanished on her way home from work in Lynbrook, Nassau County investigators say a discarded smoothie straw and cup helped identify the man they believe killed the 16-year-old. The case, one of Long Island’s most notorious cold cases, has now become a study in how forensic science can rewrite a decades-old homicide file.

Fusco was last seen on November 10, 1984, after leaving her shift at Hot Skates roller rink at 9:47 p.m. Her body was found on December 5, 1984, in a wooded area near the rink. Prosecutors say she had been raped and strangled to death. For years, the murder remained tangled in one of the region’s most damaging investigative failures.

In the 1980s, John Kogut, John Restivo and Dennis Halstead were prosecuted and convicted in the case. Those convictions were later overturned, and all three men were exonerated in 2003 after DNA testing showed they were not the killers. The case became a cautionary example of how faulty evidence handling and tunnel vision can send the wrong men to prison while the actual suspect remains free.

Authorities now say the breakthrough came in February 2024, when investigators recovered DNA from a discarded smoothie straw and cup. Prosecutors said that genetic material matched forensic evidence from the original 1984 case. That led investigators to Richard Bilodeau, 63, of Center Moriches, who was indicted in October 2025 on two counts of murder.

The result carries two meanings at once. It gives Nassau County prosecutors a new path toward accountability in a killing that haunted Lynbrook for four decades, and it closes one chapter of a wrongful-conviction saga that exposed the costs of bad forensics and rushed prosecutions. Nassau County District Attorney Anne T. Donnelly has framed the arrest as a long-awaited step toward justice for Fusco and her family.

The case is now reaching a broader audience through 48 Hours, which aired The Killing of Theresa Fusco on Saturday, April 25, 2026. Hosted by Erin Moriarty, the episode revisits how a 16-year-old’s disappearance from a suburban roller rink on Long Island became both a murder case and a test of whether modern DNA science can correct the errors of an earlier era.

Theresa Fusco’s killing showed how quickly a case can become frozen in time. Its revival shows how persistence, preserved evidence and better science can still bring movement to a file that once looked beyond repair.
