WINNIPEG, Manitoba - A man who beheaded and cannibalized a fellow passenger on a Greyhound bus in Canada won his bid to leave the grounds of the mental hospital where he is being kept, a criminal review board ruled Thursday.

The Criminal Code review board said Vince Li’s treatment team may grant him short escorted trips into the central Canadian city of Selkirk, Manitoba.

The review board said the passes will start at 30 minutes and increase incrementally to a maximum of full days. Li will have to be escorted at all times by a staff member and a security officer.

Li was found not criminally responsible for the July 2008 death of Tim McLean, a young carnival worker who was sitting next to Li on a bus near Portage la Prairie. According to testimony at his trial, Li was an untreated schizophrenic.

As part of the review, Li’s psychiatrist, Dr. Steven Kremer, described Li as a model patient, who has shown no security risks and who has participated in treatment programs.
