In the early morning hours of Aug. 26, 2022, gunshots rang out in front of a home on Kidd Crescent in Alliston.

A 38-year-old woman, later identified as Sibel Duzguner, was located on the front lawn when OPP and other emergency services responded to calls just before 6:30 a.m. Duzguner was pronounced dead shortly after being transported to the hospital.

At the time, police confirmed her death was a firearms-related murder.

The shooting and murder stunned residents on this quiet Alliston Street. Neighbours said Duzguner was the mother of three children. This was also announced on a Twitter feed that lists victims of domestic violence in Ontario. No other personal information about Duzguner has been made available.

The shooting is being investigated by the OPP Criminal Investigation Branch, OPP Identification Services, and the Chief Coroner of Ontario.

It appears to be a targeted shooting, and at the time, OPP said there was no threat to the public.

Investigators were searching for a silver or grey coloured, 2011 to 2014, Volkswagen Jetta that was seen in the area around the time the shooting occurred.

When contacted, OPP investigators said they can provide no additional information regarding this case.

Police said the investigation is ongoing, and OPP is still seeking assistance from the public with respect to the vehicle and any other information or video related to this occurrence.

If anyone has information regarding this case, they are encouraged to call Nottawasaga OPP at
