The Supreme Court of Canada ruled Thursday it will not hear an appeal from Matthew de Grood to acquire more freedoms while under psychiatric care.

De Grood(opens in a new tab) fatally stabbed five people at a Calgary house party in 2014 during a schizophrenic episode.

He was found not criminally responsible (NCR) for the deaths in 2016.

De Grood’s lawyer, Jacqueline Petrie, has been fighting to get him more freedoms while under psychiatric care.
