An Alberta man charged with the murder of his girlfriend was found not criminally responsible of two violent acts in this province.

B.C. Supreme Court justice Dev Dley ruled Friday that Mark Lindsay is not criminally responsible by reason of a mental disorder for attacks against an undercover Mountie as well as a prisoner at Kamloops Regional Correctional Centre.

Despite the finding, Dley added in non-prepared remarks that he considers Lindsay to be “an exceptionally dangerous man.”

Lindsay is now in the hands of the B.C. Review Board and will be returned to the forensic psychiatric hospital in Coquitlam for another psychiatric review.

The son of a former Edmonton police chief was found guilty in August last year of robbery, aggravated assault and possession of a weapon for a dangerous purpose for attacking an undercover RCMP member in September 2011, in Barriere. The undercover officer was investigating the death of Dana Turner, Lindsay’s girlfriend.

Lindsay was also found guilty of aggravated assault for an October 20, 2011, attack on Michel Fougere, his cellmate at KRCC. Lindsay stabbed a pencil in Fougere’s eye during a game of Scrabble.

He also admitted to killing Turner, 31, during his trial. He is charged with second-degree murder in her death.

A psychiatrist found Lindsay is a paranoid schizophrenic. He told the psychiatrist he thought the undercover Mountie was part of a gang of serial killers who were stalking him.

Lindsay also told doctors he also believed his cellmate was part of a conspiracy to kill him.

The Crown opposed the finding of not criminally responsible.

But Dley said Lindsay’s delusions rendered him incapable of making rational decisions.

“Mr. Lindsay was deluded into thinking he had no choice but to kill.”

The psychiatrist also ruled out that Lindsay faked the story, in part because he was admitted three times in Alberta to a mental hospital.

Dley said Lindsay’s mental illness delusions “rendered him incapable of the capacity to know.”

The review board will determine Lindsay’s mental state and fitness to return to the community one day. He must also return to Alberta to face the murder charge. He was under the watch of two sheriffs and bound at the ankles and wrists.
