Investigators are learning more about the gunman who killed a soldier at Canada's war memorial in the capital city Ottawa on Wednesday.

The alleged gunman has been identified as Michael Zehalf-Bibeau, who was born Michael Joseph Hall, from Quebec.

Officials say 32-year-old Zehalf-Bibeau had converted to Islam and was planning to fight for ISIS. They say the shooter, who acted alone, already had his passport revoked and had a criminal record dating back 13 years. Officials say the shooter has visited the U.S. at least four times, most recently one year ago.

Cpl. Nathan Cirillo, who was shot in the back while standing at the War Memorial where he was stationed, was the only victim of the attack, which began around 10 a.m.

Officials say within minutes the gunman launched another attack inside parliament that sent lawmakers scrambling, before the shooter was shot and killed.

Canada's Prime Minister spoke Wednesday calling the gunman a "terrorist," and said the country will not be intimidated.
