Emergency alerts relating to the incidents were issued throughout the province of Saskatchewan and later extended to Manitoba and Alberta.[4] Police quickly identified Myles and sought him and his brother Damien as suspects in the killing spree. On September 5, Damien was found dead with multiple wounds.[5] At 3:28 p.m. on September 7, after his vehicle was PIT-manoeuvred off the road by police, Myles surrendered and was arrested in Rosthern, Saskatchewan; he entered medical distress shortly afterward, and died in police custody later that day.[6][7][8] On October 6, the RCMP said there was evidence that Myles was solely responsible for all eleven homicides, including that of Damien.[9] On April 27, 2023, the RCMP issued a preliminary timeline of events before, during and after the attack.[10]
