Two patients who fled from an Ontario psychiatric hospital are in police custody after crashing their car in Quebec.

Joseph Pepin and Cara Duval were the subject of a nearly two-week police search after the pair were spotted several times in New Brunswick and Nova Scotia.

Now, Duval is in custody and Pepin is in hospital after their car crashed head-on into another vehicle in southeastern Quebec Wednesday.

Police believe Pepin, who was driving, may have crossed the centre line intentionally.

“It could be volunteer, maybe, that the driver tried to suicide on the road,” said Sgt. Claude Doiron of the Sûreté du Québec police.

The crash occurred on Wednesday in Saint-Simon-de-Rimouski, Que.

The couple were considered a significant threat to public safety after fleeing from a supervised unit of a North Bay, Ont. psychiatric hospital on Jan. 22, though police would not explain why.

Now, documents from the Ontario Review Board reveal that, separately, both Duval and Pepin were found not criminally responsible for charges including breaching court orders, uttering threats, mischief, and assault causing bodily harm.

The documents state that Pepin “suffers from Schizophrenia, Paranoid Type and Polysubstance and Cannabis Abuse.”

Duval, meanwhile, suffers from a delusional disorder, with symptoms that involve “delusions and paranoia which have given rise to violent, aggressive and threatening behaviour toward others,” the documents state.

North Bay police will now travel to Quebec to collect the couple.

The driver in the other vehicle involved in the crash received minor injuries.

Quebec police say charges related to dangerous driving offences are pending, while Ontario police have yet to say whether officers will lay additional charges.
