The partner of a Canadian man who killed 22 people in a two-day shooting rampage from a fake police car was charged Friday with providing him ammunition. Lisa Banfield is accused of illegally getting Gabriel Wortman .223-calibre Remington and .40 Smith & Wesson cartridges ahead of the killings in April. Police shot Wortman dead after a 12-hour manhunt across the eastern province of Nova Scotia, with investigators focusing on the hunt for accomplices in Canada's worst-ever mass shooting. Banfield's brother James Banfield and brother-in-law Brian Brewster were indicted on the same charges. "In light of the evidence gathered during the course of the investigation, today we have charged three people in relation to providing the gunman with ammunition," the Royal Canadian Mounted Police said in a statement. The force added however that the trio had no prior knowledge of the gunman's killing spree, which Wortmon, 51, began after attacking and tying up Banfield. She escaped and hid for hours in the woods surrounding a cottage they shared in Portapique, Nova Scotia. Police also would not confirm if the cartridges supplied by the suspects was the ammunition used in the killings. amc/ft
