Several shooting incidents occurred on 22 October 2014 around Parliament Hill and in the Centre Block, primarily in the Hall of Honour. Michael Zehaf-Bibeau, after fatally shooting Corporal Nathan Cirillo, a soldier mounting the guard of honour at the National War Memorial, made his way to Parliament Hill and to the Centre Block. There, he engaged in a firefight with Sergeant-at-Arms of the House of Commons Kevin Vickers and members of the Royal Canadian Mounted Police, which ended when he was killed by RCMP Constable Curtis Barrett.
