Vickers actually could see the barrel of Bibeau’s gun pointing out, a foot away. Vickers did not hesitate. In one motion, sources told CBC News he dove to the floor around the pillar, at the feet of Bibeau, turning on his back as he landed and simultaneously firing his weapon upwards at Bibeau.

Bibeau was hit multiple times and fell to the ground. Vickers kept firing, emptying his entire magazine. As soon as Bibeau dropped, the rest of the security team sprinted forward and opened fire. …

According to sources, Vickers calmly got up after the firing was over and went back to his office to reload his gun in case a threat remained.
