AI-generated summary

Luke Donaghey, a 26-year-old man with untreated psychotic illness, was shot by police after threatening his parents with a knife. Critical clinical lesson: his general practitioner failed to utilize available mental health services despite clear evidence of florid psychosis. The GP refused detention under the Mental Health Act, believing the patient would deny symptoms to others, and instead advised the parents to withdraw support—advice described as 'poor' by expert psychiatric testimony. The GP had prescribed benzodiazepines which may have disinhibited behavior when combined with cannabis use. A maintenance antipsychotic regimen should have been established earlier when the pattern of recurrent psychotic episodes became evident. The approach prioritized maintaining a therapeutic relationship over therapeutic intervention, resulting in a preventable psychiatric crisis that escalated to a fatal police encounter.

Contributing factors

  • failure to utilize mental health crisis services despite clear psychotic symptoms
  • general practitioner's refusal to detain patient under Mental Health Act
  • advice to withdraw parental support precipitating crisis
  • patient non-adherence with antipsychotic medication
  • ongoing cannabis use exacerbating psychotic illness
  • benzodiazepine prescription possibly disinhibiting behavior
  • lack of maintenance antipsychotic therapy despite established pattern of recurrent psychosis
  • police entry into home without high-risk tactical protocols
  • police lack of specialized mental health training

Coroner's recommendations

  1. Minister for Human Services and Attorney-General to consider amending Mental Health Act 1993 to read 'health or safety' (disjunctive) rather than 'health and safety' in Sections 12 and 20, to clarify that deterioration in health alone may justify detention
  2. Commissioner of Police to continue implementing IMOST (Incident Management and Operational Safety Training) program with rigorous annual follow-up training
  3. Department of Human Services to continue providing information and training to general practitioners about mental illness and the mental health system
  4. Commissioner of Police to review General Orders wording to ensure accessibility and clear guidance to operational officers
