A Miramichi man, who believed he was killing Satan when he fatally stabbed his mother twice in the chest, has been found not criminally responsible.

Christian Jason Godin, 41, attacked Marie Geraldine Godin, 62, with a steak knife inside the apartment they shared on April 9, 2013, and she later died, the Court of Queen's Bench heard.

He was charged with second-degree murder, but the evidence showed he was not aware of his actions that night, said Justice Fred Ferguson.

Godin was suffering from delusions at the time and believed he was the reincarnation of Jesus Christ, court documents state.

The judge said he accepted the diagnosis of two psychiatrists who found Godin suffers from "schizophrenia paranoid sub-type" and did not have "knowledge of the wrongfulness" of his actions.

Schizophrenia paranoid sub-type is considered one of the most serious of psychiatric illnesses, according to Dr. Scott Theriault, a renowned forensic psychiatrist from the East Coast Forensic Psychiatric Hospital in Dartmouth, N.S., Ferguson said.

A hearing will be held within 45 days to determine what treatment Godin will receive.

Meanwhile, Godin remains in custody in Dalhousie.

Ferguson has also ordered Godin to submit a DNA sample for the national data bank.

"Ms. Godin’s death was, and continues to be, a deeply tragic event for all of the members of this family," the judge stated in his 63-page decision.

He said it appears Godin and his mother had a "distant relationship, at least in later years."

"Regardless of the outcome of this trial, he will have to live with what he has done for the rest of his life. No outcome could likely ever surpass that sad reality," Ferguson said.
