In a video posted to YouTube Friday, RCMP Assistant Commissioner Rhonda Blackmore said police spotted an abandoned black Nissan Rogue about four kilometers east of Crystal Springs, Sask. The vehicle matched the original description and license plate of the SUV Myles Sanderson was believed to be traveling in. “The vehicle had driven off the dirt road behind trees and was not visible from the main road,” Blackmore said in the video. RCMP said the vehicle was removed from the area and will be processed as part of the investigation. The area remains closed for ongoing investigations. Police began investigating the area after a tip from a member of the public on Thursday who said he saw an unknown man walking south on a crosswalk near the intersection of Range Road 2235 and Township Road 440 on Sunday, Sept. 4 in 7:40 p.m “While it has not been confirmed to be Miles Sanderson, given the time frame and associated clothing description, we want to share this information with the public to let them know he may have been in the area,” Blackmore said. RCMP are encouraging residents to check their properties for suspicious activity as Sanderson may have been in the area. Residents in the Wakaw, Crystal Springs, Weldon and James Smith Cree Nation communities and surrounding areas are also asked to report any information about previous sightings and suspicious activity or thefts to their local police station. “When we get tips like this, investigators compare and validate them with other information we’ve already received,” Blackmore said. “It may result in the discovery of evidence, the identification of further crime scenes or even changes in potential search locations.” Crystal Springs, Sask. is about 132 kilometers northeast of Saskatoon and about 82 kilometers east of Rosthern, Sask., near where Sanderson was arrested Wednesday afternoon. Shortly after being taken into custody, Sanderson experienced a medical problem and was then taken by paramedics to hospital, according to RCMP. Speaking during a press conference in Regina on Wednesday afternoon, Blackmore said Sanderson was pronounced dead at the hospital. Before paramedics arrived, Blackmore said the Mounties were on scene rendering medical aid. Sanderson was located near Rostern, Sask., around 3:30 a.m. Wednesday after a public alert said a person allegedly armed with a knife was spotted in Wakaw, Sask. Rosthern is located 65 kilometers northeast of Saskatoon – the province’s largest city – and about 45 kilometers west of Wakaw. In an update issued Friday afternoon, the Saskatchewan Health Authority (SHA) said of the 17 people admitted with stab-related injuries, eight remain in hospital in stable condition. Nine patients were released. According to police, 11 people died, including one of the suspected attackers, and 19 were injured as a result of Sunday’s stabbing. Sanderson was charged with three counts of first degree murder, one count of attempted murder and one count of breaking and entering. Police expected to lay more charges. Police were also initially looking for Sanderson’s brother Damien, 31, in connection with the stabbings. He was found dead in a grassy area of the James Smith Cree Nation on Monday. Due to the in-custody death of Myles Sanderson, the Saskatchewan RCMP has asked the Saskatoon Police Service and the Saskatchewan Independent Response Team to conduct an external investigation into the incident. It is routine practice in Saskatchewan for an outside police agency to investigate serious police-related incidents. The RCMP also asked the Department of Justice to appoint an independent monitor as required by the province’s policing legislation. With files from CTV News Saskatoon’s Josh Lynn
