Cause of death

Cardiac arrest in a person with cardiac hypertrophy and generalised atherosclerosis whilst exhibiting features of excited delirium syndrome and self-harm who died following being placed under physical restraint by AFP officers and the application of an electrical current from a conducted electrical weapon when under the influence of very high and potentially lethal levels of methamphetamine

AI-generated summary

Anthony Caristo died from cardiac arrest on 31 October 2017 following police deployment of a taser during a mental health crisis. He had consumed a lethal dose of methamphetamine, was actively self-harming with knives, and exhibited psychotic behaviour. Police reasonably believed immediate action was required to prevent further self-harm and enable medical treatment. The taser was justified and deployed appropriately. Cardiac arrest resulted from multiple combined factors: methamphetamine toxicity, excited delirium syndrome, underlying cardiac disease, physical restraint, and taser use—no single cause identified. The coroner found no negligence by attending officers. Key clinical lesson: enhanced training on excited delirium syndrome risks, post-taser medical observation protocols, and taser restrictions for vulnerable populations (psychotic, intoxicated, mentally unwell) should be implemented to guide future police responses.

Contributing factors

  • conducted electrical weapon (taser) use
  • possible delayed breathing observation post-taser

Coroner's recommendations

  1. AFP governance and training in relation to tasers should be reviewed to enhance identifying and understanding: (a) inherent risk of taser use in vulnerable groups (psychotic, intoxicated, mentally unwell, pregnant women, children); (b) criterion for taser use; (c) use of negotiators; (d) taser use restrictions; (e) post-use medical care; (f) post-use observation; (g) positional asphyxia risk; (h) post-use rough handling; (i) excited delirium syndrome (EDS) recognition and associated vulnerabilities; (j) communication strategies in all above situations
  2. AFP to report back within 12 months on changes made to taser governance and training
  3. Standard reporting should occur in all cases involving use of force with no ad hoc exceptions
  4. AFP to conduct review or audit of communications response on 31 October 2017 to identify systemic issues regarding failure to provide available intelligence to attending officers and report back within 12 months
  5. Family submissions on CO 3 review and use of tasers should be considered by AFP
