Police asking for help in LaSalle homicide investigation

LaSalle Police are appealing for security camera footage to assist with the Nancy Grewal murder investigation. CTV Windsor’s Kate Otterbein has more.

Police are asking for the public’s help in an ongoing homicide investigation into the death of a Windsor woman in LaSalle.

On March 3 at 9:30 p.m., LaSalle police officers responded to reports of an individual in medical distress at a residence on Todd Lane.

When they got there, officers say they found a woman with serious injuries consistent with a stabbing. The victim was taken to hospital where she died from her injuries. The victim has been identified as 45-year-old Nancy Grewal of Windsor.

Upon further investigation, police say they learned Grewal went to the home on Todd Lane earlier that evening. Shortly before 9:30 p.m., as she was leaving the residence, police say she was confronted by an individual who stabbed her multiple times before fleeing the scene. Investigators believe the individual fled in a vehicle that was parked in a laneway on the extension of 10th Street, north of Todd Lane.

LaSalle police secured the residence and asked for help from the OPP Canine Unit to track the suspect.

In the days that followed, LaSalle police executed search warrants at the residence on Todd Lane and the victim’s home in Windsor. The occupants of the home on Todd Lane are not persons of interest.

Investigators believe this is an isolated incident but urge community members to remain vigilant and promptly report suspicious activity to police.

On Wednesday, March 11, LaSalle police requested assistance from the OPP. This remains an active investigation by the LaSalle Police Service, under the direction of the OPP Criminal Investigation Branch, in conjunction with the Office of the Chief Coroner and the Ontario Forensic Pathology Service.
