The murder of Tim McLean (born 1985) 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 (simplified Chinese: 李伟光; traditional Chinese: 李偉光; pinyin: Lǐ Wěiguāng), was found to be not criminally responsible for the murder.
The incident took place near Portage la Prairie, Manitoba, during a trip from Edmonton to McLean's hometown of Winnipeg.
At 12:01 a.m. on July 30, 2008, Tim McLean, a carnival worker, was returning home to Manitoba after working at a fair in Alberta. He departed Edmonton on board Greyhound bus 1170 to Winnipeg, via the Yellowhead Highway through Saskatchewan. He sat at the rear, one row ahead of the washroom. At 6:55 p.m., the bus departed from a stop in Erickson, Manitoba with a new passenger, Vince Weiguang Li. Li, described as a tall man in his 40s, with a shaved head and sunglasses, originally sat near the front of the bus, but moved to sit next to McLean following a scheduled rest stop. McLean "barely acknowledged" Li, then fell asleep against the window pane, headphones covering his ears.
