Vince Weiguang Li

On February 10, 2017, the Manitoba Criminal Code Review Board ordered Li be discharged. Li was granted an absolute discharge. There will be no legal obligations or restrictions pertaining to Li's independent living.

In February 2016, it was reported that Li had legally changed his name and was seeking to leave his group home to live independently. He won the right to live alone in February 26 upon the recommendation of the Criminal Code Review Board.

On February 27, 2015, CBC News reported that Li was given unsupervised day passes to visit Winnipeg so long as he carried a functioning cellular telephone while using them.

On May 8, 2015, CTV News reported that Li would be granted passes to group homes in the community.

Vincent (Cider Press, 2015), a book-length poem by American poet Joseph Fasano, is a fictionalized work based loosely on the event.

On February 27, 2014, the CBC reported that on March 6, Li would be allowed to have unsupervised visits to Selkirk, starting at 30 minutes and expanding to full-day trips. Since 2013, he had been allowed to have supervised visits to Lockport, Winnipeg, and nearby beaches. Those visits were then relaxed.

On July 17, 2014, the Toronto Sun reported that one of the first officers on the scene, Corporal Ken Barker of the RCMP, had committed suicide. The family stated in his obituary that he was suffering from posttraumatic stress disorder.

On May 17, 2012, the National Post reported that Li had been granted temporary passes that would allow him out of the Selkirk Mental Health Centre for visits to the town of Selkirk, supervised by a nurse and peace officer. In an interview, Li spoke for the first time, saying that he began hearing "the voice of God" in 2004 and that he wanted to save the people from an alien attack.

On February 16, 2011, two passengers, Debra Tucker, of Port Colborne, Ontario and Kayli Shaw, of London, Ontario filed a lawsuit against Li, Greyhound, the RCMP, and the Government of Canada for being exposed to the beheading. They were each seeking $3 million in damages. On July 14, 2015, the two women dropped their lawsuit.

On May 30, 2011, the CBC reported that Li was responding well to his psychiatric treatment and that his doctor had recommended that he receive more freedoms, phased in over several months.

On June 3, 2010, Li was granted supervised outdoor walks within his mental health facility as voted by the provincial review board.

Li's trial commenced on March 3, 2009, with Li pleading not criminally responsible on account of mental disorder (NCRMD) (aka insanity defense). This means he accepted that the offence occurred but claimed that he was unable to form the necessary mental element or mens rea. The psychiatrist said that Li performed the attack because God's voice told him McLean was a force of evil and was about to execute him. The presiding judge, John Scurfield, accepted the diagnosis, and ruled that Li was not criminally responsible for the killing. Li was remanded to the Selkirk Mental Health Centre.

The killing of Tim McLean 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 30 km (19 mi) west of Portage la Prairie, Manitoba, travelling the Trans-Canada Highway. On March 5, 2009, McLean's killer, the 40-year-old Chinese-Canadian Vincent Weiguang Li (simplified Chinese: 李伟光 ; traditional Chinese: 李偉光 ; pinyin: Lǐ Wěiguāng , commonly just called Vince Li) (born April 30, 1968) was found not to be criminally responsible for murder and was remanded to a high-security mental health facility in Selkirk, Manitoba, where he was detained until his release on May 8, 2015.

The incident took place near Portage la Prairie, Manitoba, during a trip from Edmonton to McLean's hometown of Winnipeg. At 12:01 p.m. on July 30, 2008, Tim McLean, a carnival barker, 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 toilet. 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.

On July 31, 2008, at 1:30 a.m., the suspect attempted to escape from the bus by breaking through a window. The RCMP arrested Li soon afterward. He was shot with a Taser twice, handcuffed and placed in the back of a police cruiser. Parts of the victim's body, placed in plastic bags, were retrieved from the bus, while his ear, nose and tongue were found in Li's pockets. The victim's eyes and a part of his heart were never recovered and are presumed to have been eaten by Li.

Li first moved to Edmonton in 2006, abruptly leaving his wife alone in Winnipeg until she joined him later. His jobs included service at a Wal-Mart, at a fast-food restaurant, and newspaper delivery. His delivery boss, Vincent Augert, described Li as reliable, hard-working and not showing any signs of trouble.

"I think he would occasionally feel frustrated with not being able to communicate or understand," Castor told CTV Winnipeg. "But we have very patient staff members and he seemed to respond well." Castor also said Li did not show any signs of anger issues or any other trouble before he quit in the spring of 2005. He worked as a forklift operator in Winnipeg while his wife worked as a waitress.

Timothy Richard McLean, Jr., was born on October 3, 1985, in British Columbia, Canada. He grew up both in Winnipeg and Elie, in Manitoba. He was 22 years old when he was killed on July 30, 2008. At the time of his death, McLean had been working as a carnival barker ("carnie").

Vincent Weiguang Li, commonly known as Vince Li, was born in Dandong, Liaoning, China, on April 30, 1968. In 1992, Li graduated from Wuhan Institute of Technology with a Bachelor of Science degree in computers. From 1994–1998, Li worked in Beijing as a computer software engineer. Li immigrated to Canada from China on June 11, 2001 (though some newspapers mistakenly reported 2004), and became a Canadian citizen on November 7, 2006. The psychiatrist Stanley Yaren, who later examined Li, said Li was hospitalized in 2003 or 2004 after an incident with the Ontario Provincial Police.
