A piece of scanner audio recorded late Saturday night is shedding light on the weekend attacks in Edmonton.
That night, a man ran down and then stabbed a police officer with his car, and later barreled through downtown Edmonton in a U-Haul.
The audio, from liveleak.com, reveals the moment police realized the U-Haul was hitting pedestrians.
The audio is intense and dramatic, and some may find it disturbing. It also contains strong language.
