Cause of death

Cardiac arrhythmia following violent exertion necessitating physical restraint in a man with methylamphetamine effect, known systemic hypertension and morbid obesity

AI-generated summary

39-year-old Chad Riley died from cardiac arrhythmia following violent exertion during physical restraint. He presented to hospital intoxicated with methylamphetamine, exhibiting drug-induced psychosis with agitation and paranoid thoughts. After leaving the ED without assessment, police encountered him at Officeworks. He made threats to kill officers, lunged at them, and attempted to seize an officer's firearm. During restraint, he was tasered multiple times and violently resisted for approximately 10 minutes. Contributing factors included methylamphetamine intoxication (causing prolonged exertion and metabolic disturbance), pre-existing hypertension and morbid obesity, intense physical struggle, and systemic physiological stress. Police actions were lawful and reasonable. Clinical lessons include recognising drug-induced psychosis as a medical emergency, implementing 'did not wait' policies for ED patients, improving Aboriginal liaison officer availability, expanding mental health co-response team hours, and emphasising risks of positional asphyxia and excited delirium in police training.

Coroner's recommendations

  1. East Metropolitan Health Service should introduce a policy for patients who do not wait for treatment, similar to WA Country Health Service's 'Management and Review of Did Not Wait Patients that Present to Emergency Services Policy'
  2. East Metropolitan Health Service should recruit additional Aboriginal Liaison Officers to ensure availability outside business hours
  3. Western Australian Police Force should make fastrap leg restraints widely available to officers and provide training on their use
  4. Western Australian Police Force should expand Mental Health Operational Response Teams to provide 24-hour coverage
  5. Western Australian Police Force should emphasise in Taser training the importance of avoiding chest and heart activations, risks of repeated activations, and recognition that prolonged resistance may create risk of fatal health events
  6. Western Australian Police Force should ensure officers confronting drug-induced psychosis request priority one ambulances and communicate all relevant patient information to attending paramedics
