Suspect in Drummondville deaths kills himself in standoff

Montreal police are taking over two investigations after a suspect in a double homicide in Drummondville turned the gun on himself during a standoff with Quebec provincial police.

Police said a man, 49, and a woman, 46, were found dead of bullet wounds Monday evening in a home on Edison Street in Drummondville, 100 kilometres northeast of Montreal.

La Sûreté du Québec received a 911 call at around 8:30 p.m. Monday.

Later, investigators were led to the town of Asbestos, 70 kilometres southeast of Drummondville, where they found a 63-year-old male suspect in the parking lot of a local bar at about 10:30 p.m.

Police said they attempted to negotiate with the man for close to four hours.

"The man had with him a weapon," said Montreal police spokesperson Simon Delorme. "During the negotiation, the man committed suicide."

The man was pronounced dead in a nearby hospital early Tuesday morning.

Under Quebec law, when a death or injuries occur in the course of a police investigation, that investigation is turned over to another designated police force — in this case, the Montreal police service.

Montreal police are investigating both incidents.
