A gunman killed an officer and injured another cop and a civilian before being gunned down during a shooting at a Montreal grocery store on Monday. Residents in the city’s Côte-des-Neiges neighborhood were told to take shelter at around 12:30 p.m. after a gunman was spotted prowling the area, the Montreal Gazette reported. Harrowing footage of the shooting shows a pair of officers engaging the gunman, who rushes at them with a rifle and camouflage clothing.
