On September 5, the RCMP confirmed one of the two suspects was found dead. Damien Sanderson was found deceased on the James Smith Cree Nation.

As a result of the ongoing investigation into the mass stabbings that occurred on September 4, Saskatchewan RCMP has now charged both men with first-degree murder.

Myles Sanderson is charged with three counts of first-degree murder, one count of attempted murder, and one count of break and enter.

Damien Sanderson is charged with one count of first-degree murder and one count of attempted murder, as well as one count of break and enter.

Warrants have been issued for their arrests. Further charges are anticipated as the investigation progresses.

"To the people of Saskatchewan and beyond – please be assured that we are using every human, and investigational and technological resource we have available to locate and arrest the persons responsible for this tragedy and to ensure your safety," said Saskatchewan RCMP Commander Officer, Assistant Commissioner Rhonda Blackmore.

Blackmore added that hundreds of Saskatchewan RCMP staff are dedicated to this investigation, including operators taking 911 calls and tips, frontline officers patrolling the streets to the on-scene specialized forensic and Major Crime Unit teams who continue to follow up on all information and evidence gathered.

Investigators have confirmed there are ten deceased victims. In addition, there are now 18 individuals reported as injured.

"Yesterday, Saskatchewan RCMP issued a dangerous person alert and several subsequent updates. This alert will be extended and we urge residents to continue to remain vigilant until Myles and Damien Sanderson are located and arrested," an RCMP press release stated. 

Damien Sanderson is described as a 31-year-old male, 5 foot 7, 155 pounds, with black hair and brown eyes. Myles Sanderson is a 30-year-old male, 6 foot 1 and 240 pounds with brown hair and brown eyes. They are armed and dangerous and should not be approached.

Myles and Damien Sanderson were last known to be driving a black Nissan Rogue with Saskatchewan license plate 119 MPI. It is believed they may be in Regina, but this has not been confirmed.

The RCMP is also advising that those returning home after long weekend travels, should look for evidence of suspicious activity at and around their home before entering it and if they notice anything suspicious, to report it to the police.
