Four years ago in Manitou Canada, a Chinese immigrant named Vince Li was riding on a Greyhound bus. His neighbor was asleep beside him. Suddenly Li leapt up and began stabbing his victim. Horrified passengers ran from the bus while Li proceded to carve up and eat his victim, at one point showing the severed head to the passengers outside the bus. Arresting officers found several baggies with body parts strewn about the bus and the victim’s tongue in Li’s pocket. Li claimed that he thought the passenger was an alien demon and destroyed him to protect the passengers.
