Correction to my initial post...
CBC News is now saying that Cst. Gignac was only hit once. Three shots were fired from a .338 calibre rifle. The round that struck Cst. Gignac went through a door, her front ballistic panel, her body, her back ballistic panel, and then a wall. The accused was prohibited from owning firearms, but had been granted an exception through the courts to allow him to possess a firearm when hunting.
