Authorities have identified the shooter at the Canadian Parliament building as 32-year-old Michael Zehaf-Bibeau.

A government official confirms to Fox News that investigators believe Zehaf-Bibeau changed his name from Michael Joseph Hall.  U.S. agencies have been advised that the shooter was believed to be a Canadian convert to Islam, and they think he was from Quebec.

Local reports say Canadian authorities knew he was designated a high-risk traveler and that his passport had recently been confiscated.

Authorities still do not know the motive behind the attack, which left one soldier dead.
