Hearing gunshots, Vickers grabbed his side arm, an automatic pistol, and immediately ran out. His security team, who had been chasing Bibeau, yelled to Vickers that the suspect was hiding in the alcove.

Vickers immediately ran behind the other side of the pillar. That put him an arm's-length away from Bibeau.

According to guards, 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 clip.

As soon as Bibeau dropped, the rest of the security team sprinted forward and opened fire.

Nine bullet holes in the walls in the alcove give a sense of the numbers of rounds fired, and many more hit Bibeau.

One bullet passed right through the wooden library doors, hitting the librarians' desk deep inside.

But no one else was injured in that final exchange of gunfire.
