A 33-year-old suspect, who was injured in a car crash after the incident, is in custody.
Two women are dead after being attacked Monday night in the Laurentian town of Ste-Sophie.
The Sûreté du Québec on Tuesday reported that the murder victims were related and aged 60 and 28.
The SQ learned of the attacks after a 911 call was made at about 9:15 p.m. The victims were found soon after in a residence on Samson St. and taken to a hospital. The older victim was declared dead Tuesday morning; the death of the second victim was confirmed Tuesday afternoon.
At about the same time the incident was reported, a car driven by a motorist believed by police to be the suspect collided with another vehicle in St-Jérôme, a few kilometres away from the crime scene.
The 33-year-old man was seriously injured in the crash and taken to a hospital, as was the other driver involved in the collision. Police said their injuries are not life-threatening.
Two crime scenes — one in Ste-Sophie, the other in St-Jérôme — have been set up and the investigation has been assigned to the SQ’s major crimes squad.
