Toronto police are working with international law enforcement agencies to track down a man who was found not criminally responsible in the death of his roommate.
They say 47-year-old Zhebin Cong was reported missing on July 3 and has since left the country.
The Centre for Addiction and Mental Health says Cong is one of their patients.
Records from the Ontario Review Board, which evaluates the status of anyone found not criminally responsible, show Cong had been detained at CAMH and in June 2018 was allowed to live in the community in approved, 24-hour-supervised accommodation.
Documents from the board show Cong killed his roommate with a meat cleaver in 2014 and was found non-criminally responsible for his actions.
Toronto Mayor John Tory called the entire situation troubling and said he had many questions about Cong's disappearance.
