WINNIPEG - A Manitoba review panel says in the interests of assessing whether Vince Li could ever be reintegrated into society, he should be allowed to take short, supervised walks around the grounds of the Selkirk Mental Health Centre.

That's part of a detailed explanation released by the Criminal Review Board of Manitoba into why they are backing the walks for Li, who beheaded a fellow passenger two years ago on a Greyhound bus.

The board says such small measures are necessary in order to assess Li's progress.

Panel members also say they believe Li's risk of "elopement" is low, as he hasn't expressed any desire to escape custody.

They also say that although Li has continued to report having auditory hallucinations in the last year, "these were greatly reduced in frequency and intensity."

The decision to grant the walks has been opposed by relatives of the victim and the attorney general's office, but supported by the Canadian Psychiatric Association.
