Police in Canada are seeking the final suspect in a mass stabbing that resulted in the deaths of ten people after one of the suspects' brothers was found dead.

On Monday, the body of Damien Sanderson, 31, was discovered near where he was stabbed in the rural prairie region of Saskatchewan's James Smith Cree Nation.

His injuries were not self-inflicted, although the official cause of death has not yet been determined.

His brother, Myles Sanderson, 30, remains on the run and is believed to be in Regina, the provincial capital of Saskatchewan.

Rhonda Blackmore, Assistant Commanding Officer of the Royal Canadian Mounted Police, stated that Damien Sanderson's body was discovered "located outdoors in a heavily grassed area in proximity to a house that was being examined."

We can establish that he has visible wounds.

The police are examining whether or not Damien Sanderson caused the death.

He is believed to be in Regina, which is more than a three-hour drive from the James Smith Cree Nation. Alerts have been sent throughout Alberta, Manitoba, and the United States.

The stabbings have stunned Canada, as 18 people were injured during the September 4 spree.

Locals in the James Smith Cree Nation have attributed the killings to drug and alcohol misuse. This social issue has been attributed to the impact of colonization on North American indigenous peoples, while authorities work to put together what transpired and track down the final brother.

Gloria Burns, a member of a crisis response team that responded to the stabbings and was slain, was the sister of Darryl Burns, who told the Associated Press: "We had a murder-suicide here three years ago. My granddaughter and her boyfriend.

Last year there were two homicides. This year, ten more people have died due to the effects of drugs and alcohol."
