DNA Breakthrough: Killer of Theresa Fusco Finally Identified After 41 Years
26 Apr
Summary
- Theresa Fusco was murdered in 1984; her killer was identified 41 years later using DNA.
- An initial conviction of three men was overturned due to new DNA evidence.
- Richard Bilodeau, 63, was arrested in October 2025, identified by genetic genealogy.

In 1984, 16-year-old Theresa Fusco was murdered in Lynbrook, New York. Her case remained unsolved for decades, marked by initial convictions that were later overturned in 2003 due to advancements in DNA technology. This new evidence exonerated John Kogut, John Restivo, and Dennis Halstead, who had been imprisoned for her rape and murder.
In October 2025, a significant breakthrough occurred when 63-year-old Richard Bilodeau was arrested. Authorities utilized genetic genealogy to match an unidentified DNA sample from the crime scene to Bilodeau, who lived near the location of Fusco's murder in 1984. This new scientific evidence has brought renewed hope for justice.
The original investigation faced challenges, including a coerced confession from John Kogut, which was later deemed inadmissible. The overturned convictions led to lawsuits against Nassau County. The current District Attorney, Anne Donnelly, stated that the scientific evidence is now irrefutable.
While Bilodeau faces charges for Fusco's murder, the disappearances of Kelly Morrissey and Jackie Martarella, which occurred around the same time, remain unsolved. Fusco's family and friends anticipate a trial, hoping for final closure after a 41-year ordeal.
