Video Details Canada Killer's Moves

80 seconds from shooting soldier to hitting Parliament.

A compilation of security videos has revealed the clearest picture yet of how gunman Michael Zehaf-Bibeau carried out his attack in Ottawa. According to the video it took just 80 seconds for Zehaf-Bibeau to go from fatally wounding Cpl. Nathan Cirillo to finding himself one unlocked door away from Canadian Prime Minister Stephen Harper and the entire Conservative caucus. The video, released by the Royal Canadian Mounted Police, reveals that after shooting Cirillo at the National War Memorial, Zehaf-Bibeau got in his car and made a U-turn in the direction of Parliament and entered the building, where he eventually was shot to death. Authorities said Zehaf-Bibeau was "radicalized,' and they are investigating possible links between him and jihadists.
