Niagara Falls police have launched a homicide investigation after identifying the remains of a woman found during a 2023 home demolition. The deceased, Brenda Marie LeBlanc, may have been at the site since the 1990s.

The role of Othram Laboratories in identifying Brenda Marie LeBlanc

The identification of the deceased was made possible through the use of genetic genealogy, a process that merges DNA analysis with family tree tracing. As The Canadian Press reported, this effort involved a multi-agency collaboration between the Toronto Police Service, the Ontario Forensic Pathology Service, and Othram Laboratories, a specialized firm based in Texas.

By utilizing these advanced forennsic tools, investigators were able to confirm that the remains belonged to Brenda Marie LeBlanc, who was born in 1963. This technological leap allowed police to move from an "unknown" status to a named victim, transforming a discovery of remains into a targeted criminal investigation.

The Stanley Avenue property's transition from residence to shelter

The site where the remains were discovered was a vacant property located on Stanley Avenue in Niagara Falls, Ontario. According to The Canadian Press, the building served as a multi-unit residence from the 1970s until 2018, after which it became a frequent site of shelter for individuals experiencing homelessness.

The fact that the property remained in use—first as a formal residence and later as an informal shelter—adds a layer of complexity to the investigation. The transition of the Stanley Avenue home suggests that the remains may have been hidden or overlooked for decades despite the building's continued occupancy by various groups.

A decades-long silence since the 1990s

Investigators believe the death of Brenda Marie LeBlanc likely occurred many years ago, potentially dating back to the 1990s. During that decade, LeBlanc, a native of New Brunswick, resided within the Niagara Region while in her 30s.

This timeline places the crime in a broader trend of "cold case" resolutions currently sweeping through North American law enforcement. As forensic genealogy becomes more accessible, police departments are increasingly able to identify victims who disappeared decades ago, often revealing that individuals who were presumed missing or had simply "moved on" were actually victims of foul play.

The unknown connection between LeBlanc and the Niagara Falls home

Despite the identification of the victim, a critical piece of the puzzle remains missing: why Brenda Marie LeBlanc was at the Stanley Avenue property. Niagara Falls police have explicitly stated that her connection to the house is currently unknown.

Police are now urging anyone who knew LeBlanc or has information regarding her disappearance to come forward. The central question for investigators is whether LeBlanc lived at the property , was visiting someone there, or was brought to the location by a third party.. Because the remains were found during a November 2023 demolition, the physical evidence at the scene has been significantly altered, making witness testimony the primary path toward a suspect.
