MONTREAL - Police interrogated a 12-year-old boy in Montreal for several hours early Tuesday morning in the shooting death of his teenage brother.
It's believed the younger boy unintentionally discharged a pistol and that the older boy was fatally shot in the head.
It happened early Monday evening in a suburban neighbourhood near Trudeau Airport west of Montreal, and police questioned the boy until 5:30 Tuesday morning.
Investigators have ruled out murder but the boy could still face charges.
"It could be charges associated with the use of a weapon, or ... manslaughter," police spokesman Simon Delorme told QMI Agency.
The boys were by themselves in their home when a handgun went off around 6 p.m.
The 16-year-old was pronounced dead in hospital. His mother arrived home and was also taken to hospital to be treated for shock.
It was not immediately clear if the weapon was easily accessible to the brothers.
Asked if the firearm was registered, Delorme said the information would be kept secret "so as not to influence potential witnesses who will be met during the day."
Quebec's public security minister, Stephane Bergeron, said Tuesday that the killing highlights the need for gun registration.
"Obviously this is a very sad story, and it indicates to me that it is absolutely imperative to move forward with our plan to control firearms," he said.
The province plans to create a provincial gun registry after successfully persuading a judge to block the federal Conservatives from destroying data on Quebec gun owners.
