In the case of Tim McLean, a young man dismembered and cannibalized while riding home on a Greyhound bus bound for Winnipeg, the details are beyond words. They would leave an indelible mark on witnesses and put the normally tame Canadian justice system to the test. This bus ride gone horribly wrong would not only cost the 22-year-old victim his life, but it exposed the frightening reality of mental illness run rampant.

When Vincent Li, a diagnosed schizophrenic, randomly boarded the bus that day, no one could have ever anticipated the depth of his depravity or the severity of the voices in his head. Later dubbed the Canadian Cannibal, Li committed one of the most shocking and unbelievable offenses of the decade that night, reminding anyone who heard the tale that humans are, indeed, the real monsters. What makes the case truly stunning, however, are not the grisly details but the fact that Vince Li is now a free man.
