MONTREAL – A police officer was killed while responding to a domestic dispute in the Canadian province of Quebec by a suspected gunman who likely committed suicide, authorities said on Sunday. The incident happened in the aboriginal community of Lac Simon in the west of the largely French-speaking province. Two officers were responding to a call about a dispute at a home late on Saturday, when one of them was fatally wounded by at least one shot fired in their direction, Sergeant Benoit Coutu of Quebec’s provincial police told AFP. The suspected shooter was later found dead in the home, after “in all likelihood turning the gun on him,” Coutu said.
