Who Was Theresa Fusco & What Happened to Her? 2026 Update & Profile

by · April 24, 2026

CBS’s 48 Hours episode The Killing of Theresa Fusco brings renewed attention to the life and death of a Long Island teenager whose case has spanned more than four decades. The program centers not only on the investigation, but on Theresa Fusco herself, a 16-year-old whose disappearance in 1984 left a lasting impact on her family and community.

Theresa Fusco: A Teenager With Plans for the Future

Theresa Fusco was a high school student in Lynbrook, New York, known by family and friends as responsible and close to home. She had interests in dance, including ballet and tap, and hoped to build a future connected to that passion. Those who knew her described a teenager who maintained strong ties with her family and kept in regular contact, even during routine outings.

Her home life reflected a typical upbringing. Despite her parents being divorced, she remained closely connected to them and to extended family members. She was not considered a runaway risk, and her routines were predictable. That sense of normalcy is what made her sudden disappearance deeply alarming.

The Night Theresa Disappeared

On November 10, 1984, Theresa was working at the snack bar at the Hot Skates roller rink in Lynbrook. That evening, she was fired from her job and left the rink at around 9:45 p.m. Witnesses saw her walking home, a short distance of only a few blocks.

She never arrived. When Theresa failed to return home, concern escalated quickly. Her disappearance came just months after her friend Kelly Morrissey had vanished, which added a layer of fear within the community. Families in the area began to question whether the cases were connected.

The Discovery That Confirmed Fears

Nearly a month later, on December 5, 1984, Theresa’s body was discovered in a wooded area near railroad tracks, not far from where she had last been seen. She had been covered with leaves and debris, indicating an attempt to conceal the crime.

The medical examination determined that Theresa had been sexually assaulted and killed by ligature strangulation. The details confirmed the worst fears of her family and marked the beginning of a long and complicated investigation. Her death became a major case for Nassau County authorities, who faced growing pressure to find answers.

A Community Gripped by Fear

Theresa’s murder did not occur in isolation. Earlier that year, 15-year-old Kelly Morrissey had disappeared and was never found. In March 1985, another young woman, 19-year-old Jacqueline Martarella, also went missing and was later found dead.

These cases created a sense of panic in the Lynbrook area. Residents began referring to the situation as a pattern of unexplained disappearances. Parents feared for their children’s safety, and the pressure on law enforcement intensified as the community searched for reassurance.

The Investigation and Early Conclusions

In 1985, police arrested three men in connection with Theresa’s murder. Investigators said one of the men, John Kogut, confessed and implicated two others, John Restivo and Dennis Halstead. All three were later convicted in 1986.

The case appeared resolved at the time, but questions persisted. The convictions relied heavily on confessions and forensic methods that would later be challenged. Theresa’s family, like many others, believed justice had been achieved, though the full truth of what happened remained uncertain.

DNA Evidence Reopens the Case

Years later, advances in DNA testing changed the direction of the case. Testing on evidence collected during the original investigation showed that none of the three convicted men matched the DNA profile recovered from Theresa’s body.

In 2003, their convictions were vacated, and they were released from prison. A retrial for John Kogut ended in acquittal in 2005, and charges against the other two men were dismissed. The case returned to an unsolved status, leaving Theresa’s family once again without clear answers.

A Breakthrough Decades Later

The investigation remained open for decades until new forensic methods allowed investigators to reexamine the DNA evidence. Using advanced techniques and investigative genealogy, authorities identified a new suspect.

In 2024, investigators recovered a discarded smoothie cup and straw linked to the suspect. DNA from that straw matched the profile taken from Theresa’s body. This development marked the first time the DNA evidence had been connected to a specific individual.

Where the Case Stands Today

In October 2025, Richard Bilodeau was arrested and charged with Theresa Fusco’s murder. He has pleaded not guilty, and the case is ongoing. Prosecutors allege that the DNA evidence establishes a direct link, while the legal process will determine the outcome.

For Theresa Fusco’s family, the developments represent a shift in a case that has remained unresolved for most of their lives. The story of Theresa Fusco is one of loss, prolonged uncertainty, and the evolving role of forensic science in seeking justice many years after a crime.
