Sudbury Police say the 63-year old man who was barricaded in a residence on Sunny Street in Garson has been found dead in the home.

Shortly after 12:30 pm today, members of the Barrie Police Service Tactical Support Unit entered the residence after they could no longer establish communications with the man and officers could no longer see movement.

Officers found the 63-year old man dead inside the home.

The Special Investigations Unit has invoked a mandate prohibiting Sudbury Police from releasing any further information.

The standoff lasted more than 18 hours.

The incident began at 6:15 last night when a 57-year old woman was taken to hospital with serious but non-life threatening injuries from gunshot wounds.

Barrie Police were called as the local tactical unit had been working through the night and their tactical team was the closest available unit not because they had more experience with these situations.

The investigation continues.
