So this story is a few years old but I came across this tonight..
The murder of Tim McLean (October 3, 1985[1] – July 30, 2008) occurred on the evening of July 30, 2008. McLean, a 22-year-old Canadian man, was stabbed, beheaded and cannibalized while riding a Greyhound Canada bus about 18 miles (29 km) west of Portage La Prairie, Manitoba traveling the Trans Canada Highway. On March 5, 2009, McLean's killer, 40-year-old Vince Weiguang Li (born April 30, 1968), was found to be not criminally responsible for the murder and was remanded to a high-security mental health facility where he remains to this day.[2]
