NEW WESTMINSTER, B.C. - A man who confessed to killing the house manager at an addiction treatment centre New Westminster, B.C., has been found not criminally responsible for the death because of a mental disorder.

Steven Rogers was charged with second-degree murder shortly after 38-year-old Jason Collett was killed with a hammer and knife on Sept. 16, 2014.

Three psychiatrists gave evidence at his B.C. Supreme Court trial in New Westminster in February that Rogers was in a state of psychosis when he killed Collett because of underlying mental disorder.

The trial heard that Rogers told police days after the murder that he believed he was guided by something and in order to save Collett's soul and the souls of everyone else, he had until 2:26 a.m. that morning to kill the man.

A Crown attorney told the trial Rogers didn't like Collett, and several residents at the Last Door treatment centre where Rogers was being treated for addiction gave evidence of heated discussions between the two men.

But Justice Elliot Myers ruled in a decision published Friday that Rogers was not criminally responsible because he was in a state of psychosis as a result of schizophrenia.
