I’m guessing he was a Muslim convert who wanted to join ISIS.

Federal sources have identified the suspected shooter as Michael Zehef-Bibeau, a man in his early 30s who was known to Canadian authorities.

Sources told The Globe and Mail that he was recently designated a “high-risk traveller” by the Canadian government and that his passport had been seized – the same circumstances surrounding the case of Martin Rouleau-Couture, the Quebecker who was shot Monday after running down two Canadian Forces soldiers with his car.

This is the picture the Islamic State Media accounts are purporting to be Michael

(Reuters) – Canadian police are investigating a man identified as Michael Zehaf-Bibeau as a possible suspect in the shootings on Wednesday around parliament in Ottawa, a source familiar with the matter said.

Police said the male suspect in the attacks was dead but did not confirm he was Zehaf-Bibeau. Some U.S. government sources said the shooter was born Michael Joseph Hall but changed his name to Zehaf-Bibeau.

Two U.S. officials said that U.S. agencies have been advised that the shooter was a Canadian convert to Islam. One of the officials said the man was from Quebec.

The Canadian Security Intelligence Service declined to comment on the gunman’s identity.

Canada’s capital was jolted by the fatal shooting of a soldier and an attack on the parliament building on Wednesday, with gunshots fired outside a room where Prime Minister Stephen Harper was speaking.

The shooting was the second attack on Canadian soldiers in a week.
