WINNIPEG, Manitoba - A man who witnesses said stabbed, beheaded and cannibalized a fellow traveler on a Greyhound bus immigrated to Canada from China four years ago and worked for a time as a church custodian, the pastor who employed him said.

Passengers on the bus described a horrific scene that began late Wednesday as they shuttled through the darkness along a desolate stretch of the TransCanada Highway about 12 miles from Portage La Prairie, Manitoba.

Thirty-seven passengers were abroad the Greyhound, some napping and others watching "The Legend of Zorro," when Li suddenly attacked his seat mate, 22-year-old Tim McLean.

Li allegedly stabbed McLean several dozen times as others fled the bus, witnesses said. He then severed McLean's head, displayed it to the frightened passengers gathered outside the bus and began hacking at the body. A police officer at the scene reported seeing the attacker hacking off pieces of the victim's body and eating them, according to a police tape leaked on the Internet.
