In Edmonton, Alberta there was an incident on a bus where a man suddenly started stabbing another sleeping passenger with a butcher knife. The rest of the passengers started screaming and running to get off the bus. A few of them went back to try and save the victim, but the killer started decapitating him. He then went after the people who had gotten off the bus, but thankfully they closed the door in time and he was only able to get his knife through the door.
The killer was a 40 year old, 6 foot tall asian man.
