Brenda Marie LeBlanc

For nearly three decades, she was a woman without a name, her story silenced and her fate unknown. She was originally from New Brunswick, a province on Canada's east coast, but had made her way to Ontario, living in the Niagara region in the 1990s when she was in her 30s. Her name was Brenda Marie LeBlanc, a female born in 1963, and her life was cut short in a mystery that is only now beginning to unfold.

The first chapter of this long-dormant story began on November 8, 2023, in Niagara Falls, Ontario. A demolition crew was at work at 7081 Stanley Avenue, tearing down a vacant house. The property had once been a multi-unit rental home from the late 1970s until about 2018. After that, it sat empty for years, a target for unlawful entry by unhoused individuals. As the structure came down, a shocking discovery was made: human remains were hidden within.

The Niagara Regional Police Service (NRPS) Homicide Unit launched an extensive investigation. Forensic and anthropological examinations determined the remains belonged to an adult female. The analysis also revealed a chilling timeline, suggesting the body had been at the location for many years, likely since the mid-1990s. Despite exhaustive efforts using traditional methods like fingerprint and dental record comparisons, her identity remained a mystery. For almost two years, she was a Jane Doe, her case growing cold.

In 2025, investigators turned to a cutting-edge technique called Investigative Genetic Genealogy (IGG). In a collaborative effort with the Toronto Police Service, the Ontario Forensic Pathology Service, and Othram, a private lab in Texas, forensic specialists developed a comprehensive DNA profile from the remains. By comparing this profile against genealogy databases, researchers were able to build a family tree, generating new leads that pointed toward a possible identity. Traditional police work confirmed the findings, and the Jane Doe of Stanley Avenue was finally identified as Brenda Marie LeBlanc.

In August 2026, the Niagara Regional Police publicly announced Brenda's name, officially classifying her death as a homicide. Investigators have determined that Brenda lived in both Niagara Falls and St. Catharines during the 1990s, but they have not yet established how she came to be at the Stanley Avenue address or what her connection was to the residence. The owners of the property have been cooperative throughout the investigation.

Police believe that even after decades have passed, there are people who remember Brenda. Someone may have known her, been her friend, or recalled her associates, her activities, or where she lived during that time. "Although decades have passed, investigators believe that there are individuals who may have known Brenda or have information that could assist in determining the circumstances surrounding her death," police stated. They emphasize that any piece of information, no matter how small it might seem, could be the key to understanding what happened to her.

The investigation into who killed Brenda Marie LeBlanc is active and ongoing as of August 2026. The Niagara Regional Police Service is appealing to the public for help in piecing together the last years of her life. Detectives are asking anyone who knew Brenda during the 1990s or has any information about her whereabouts or associates to come forward. A dedicated hotline has been established for tips at (289) 248-1058.
