The Afternoon Edition - Sask13:01Public coroner's inquest into Myles Sanderson's death underway

CBC's Dan Zakreski has been at the coroner's inquest into the death of Myles Sanderson all week. He joins host Peter Mills to talk about what happened before and after Sanderson was caught by police. 

Earlier this week, the inquestheard from Saskatchewan's chief forensic pathologist that Sanderson haddied of "acute cocaine overdose," and that his arrest by the RCMP did not cause or contribute to his death.

Jurors at the inquest also provided four recommendations for police services, includingthat the Saskatoon Police Service consider establishing a dedicated team tasked with arresting individuals who are subject to outstanding warrants.

The three other recommendations were directed to the RCMP:

• Consider implementing mandatory enhanced driver training, includinga specific tacticused in pursuits to force another vehicle to abruptly turn.
• Consider a policy review ofcriteria in high-speed pursuits in the interest of the safety of all involved.
• Consideradditional training in the form of enhanced extraction techniques for arrest takedowns.

Eddie Head, Sanderson's uncle, said the inquest brought closure to the community and his family.

"What was the last days of his life? Where he was, what did he do?" said Head, whohad standing at the inquest, meaning hecould ask questions of the witnesses on behalf of Sanderson's family.

Eddie Head, uncle of Myles Sanderson, represented the family at a coroner's inquest. He says Myles's mother, Beverly, who felt she failed her son, can move forward with her family and community after the inquest.

He still wonderswhat Sanderson did between the killingson Sept. 4 and his arrest on Sept. 7.

Inquest testimony confirmed some reported sightings of Sanderson, and that he was stealing from a home near Wakaw and camping nearby, but did not delve into a specific timeline.

Sanderson had a plan:forensic psychologist

The jury heard from the last two inquest witnesses Thursday morning.

Forensic psychologist Dr. Matthew Logan testifiedthat Sanderson was found to be "mission-oriented" in his killings and had developed somewhat of a plan before he killed 10 people in his home community of James Smith Cree Nationand one person in Weldon.

At the time of his arrest, Sanderson was likely on his way to Saskatoon to kill his former common-law partner, Logan said.

Sanderson "pumped himself up with cocaine, stole a vehicle and moved toward other potential targets,"Logan said, quoting from his report.

The psychologist had never met Sanderson, but co-authored a post-mortem behavioural analysis based on his investigation.

Logan said Sanderson targeted people who he felt had wronged himand those connected with the Terror Squad gang, describing him as a mission-oriented offender.

He said those types of offenders typically do not kill people who aren't their specific targets like the woman whose truck Sanderson stole near Wakaw, Sask., on Sept. 7 unless they get in their way.

Coroner's counsel Timothy Hawryluk says the gift of a painting from James Smith Cree Nation Chief Wally Burns and Eddie Head, who represented the Myles Sanderson's family at the inquest, means "the world" to him. The artwork is by Jerry Whitehead, a famed James Smith Cree Nation artist.

After stealing the truck, Sanderson led police into oncoming traffic southbound on Highway 11, toward Saskatoon, as they chased after him.

While he could have been searching for refuge with his father in Saskatoon, Logan believes Sanderson was on his way to kill Vanessa Burns, his former common-law partner and the mother of his children.

Logan testified that Sanderson's recent violence toward Burns likely triggered his plan to massacre people at James Smith Cree Nation.

As he drove into oncoming traffic on Highway 11 at breakneck speeds, forcing dozens of vehicles to the shoulder or the ditch, Sanderson was ambivalent to death, Logan testified.

"It's really a voluntary self-killing where you're doing so knowingly, recklessly but not purposefully," Logan said.

Sanderson showed severe psychopathic traits, Logan testified. Compared to other inmates scored at Canadian institutions, he ranked in the 94th percentile.

Delving into Sanderson's past

Logan noted a report from the Saskatchewan Penitentiary that said Sanderson had thought of suicide.

He testified that he believes Sanderson likely didn't mean to overdose on cocaine referencing the testimony of the forensic pathologist given on Tuesday that marked an overdose as his cause of death but that he could have taken the substance with reckless regard.

Logan's behavioural analysis included examining photos of the crime scenes, Sanderson's past and interviews with family members of those killed and others impacted.

Coroner's counsel Tim Hawryluk said the behavioural analysis report Logan co-authored is an "extremely rare" request among public inquests.

Logan testified that Sanderson's childhood was "rife with abuse and instability." He also started using drugs when he was 13 and, in recent years, used cocaine "considerably."

Week-long inquest

The inquest also heard from the physician, Dr. William Papenfus, who called Sanderson's time of death at Royal University Hospital at 4:39 p.m. CST on Sept. 7, 2022.

He testified that when Sanderson arrived at the hospital while flatlining for the journey from the scene off Highway 11 between Rosthern and Hague, Sask. a trauma room was waiting for him.

Papenfus said doctors continued life-saving measures.

Doctors were told Sanderson may have ingested some sort of white powder and that he had rapidly deteriorated from an excited state before his cardiac arrest. He said doctors confirmed with an ultrasound that Sanderson had no heart activity.

Since Monday, jurors heard testimony from Saskatchewan Mounties recounting the harrowing police pursuit, paramedics who testified about their life-saving efforts, and opinions from a forensic pathologist and toxicologist.
