DNA Solves 40-Year Mystery: Long Island Teen’s Suspected Killer Identified

The 1980s saw tragic events that haunted the Long Island community for decades. Particularly, the disappearances of two teenagers, Kelly Morrissey and Theresa Fusco, captured the attention of local authorities and families alike.
The Disappearances of Kelly Morrissey and Theresa Fusco
On June 12, 1984, 15-year-old Kelly Morrissey left her Lynbrook home after dinner. She never returned. Just five months later, on November 10, 1984, 16-year-old Theresa Fusco vanished after leaving her job at Hot Skates, a local roller rink.
At the time, Long Island was vastly different. There were no cell phones or social media. Children roamed freely, and safety was often taken for granted. Kelly, who had moved to Lynbrook a year earlier, had quickly made friends, including Theresa, and often communicated by letter.
The Investigation and Initial Response
Initially, police treated Kelly’s disappearance as a runaway case. After Kelly was reported missing, her family’s search began. Iris Olmstead, Kelly’s mother, recalled the moment she realized her daughter was truly missing. “It was horrible,” she remembered, expressing the confusion and fear that swept through her family.
Months passed without any sign of Kelly. When Theresa was reported missing, investigators revisited Kelly’s case, realizing a pattern of disappearances among young girls. Investigators launched extensive searches for Theresa following her disappearance, but it took nearly a month to find her body. Her remains were discovered near the Long Island Rail Road tracks, revealing a shocking truth—she had been murdered.
The Arrest and Legal Battles
In 2005, after prolonged investigations and trials, John Kogut and his accomplices were convicted for Theresa’s murder. Kogut had confessed to the crime, laying out a gruesome account of events on videotape. However, Kogut later recanted, leading to further legal implications.
After almost two decades, advancements in DNA testing prompted a reexamination of the case. In 2003, new DNA evidence led to the exoneration of Kogut and his co-defendants. The DNA matched an unknown male, reigniting the search for the true killer.
Recent Breakthrough in the Case
In October 2025, significant advancements in genetic genealogy finally yielded results. Authorities identified Richard Bilodeau as the suspect in Theresa’s murder. Bilodeau, then 63 years old and living in Center Moriches, was arrested after DNA connected him to the crime scene. He was working at Walmart at the time of his arrest.
Despite the arrest, Bilodeau’s defense team expressed skepticism about the evidence, questioning its reliability and drawing attention to previous erroneous convictions in the case. The court proceedings are anticipated to unfold as both families seek closure after more than 40 years.
Unsolved Cases and Ongoing Legacy
While justice may be served for Theresa, the cases of Kelly Morrissey and Jackie Martarella—another teenager who disappeared in March 1985—remain unsolved. Families affected by these tragedies continue to seek answers and justice for their loved ones.
The developments in the ongoing investigation underscore the enduring impact of these cases on the Long Island community. As the legal process unfolds, many hope to see a resolution that honors the memories of these young girls and provides their families the closure they desperately need.
