ASIRT clears police in death of Calgary man during mental health call

Alberta's police watchdog says it found no grounds to believe Calgary officers had committed an offence when a man died after being restrained during a mental health call three years ago. 

In its report released Friday about the April 2020 incident, the Alberta Serious Incident Response Team said the man's mother called 911 for medical assistance as the man was having a psychotic episode. He had schizophrenia and thought he was on fire. 

Two paramedics arrived and waited for police officer backup due to safety concerns, ASIRT said. The agency said the man was lying face down when one officer and the two paramedics arrived and helped him to his feet. 

"They tried to speak with [the man] but he took an apparent aggressive posture and lunged forward," the report said. 

A review of video footage from a body-worn camera described the man's movement as "steps or stumbles forward" toward one of the paramedics. 

The report said a police officer used the man's forward momentum and took him to the ground. It said the officer "laid on [him] for a relatively short period of time," in a semi-face down position, until a second officer arrived. 

The second officer used his baton to pry the man's arm out from under his body and he was handcuffed. 

One of the paramedics realized the man had vomited and they placed him in a recovery position, ASIRT said. He was brought to an ambulance and paramedics started trying to resuscitate him as he wasn't breathing. 

The man was brought to hospital and was pronounced dead, ASIRT said. 

Following an autopsy, the medical examiner initially determined the immediate cause of death to be excited delirium, with schizophrenia and the struggle during police restraint as significant conditions contributing to death but not causally related, ASIRT said. 

Excited delirium is a highly contentious term that describes a state of agitation, aggression and distress generally linked to drug use or mental illness. It's been used as an explanation for sudden, unexpected deaths during interactions with police.

"Excited delirium as a stand-alone cause of death has been questioned by some in the medical field," the report said.

"The medical examiner who conducted this autopsy was subsequently consulted about his report, and he advised that his findings during the autopsy remain the same, but he would now describe the immediate cause of death to be complications of schizophrenia and struggle during police restraint." 

The report also details bruises and scrapes to the man's arms and legs.
