AI-generated summary

Stacey Docherty, a 38-year-old woman with complex post-traumatic stress disorder and borderline personality disorder resulting from childhood sexual abuse, killed her 3-year-old son Seth before taking her own life in March 2017. Key clinical lessons include: inadequate communication between Stacey's psychiatrist and general practitioner regarding medication (Alprazolam dose increasing above authorized limits, concurrent Tramadol prescription not discussed); suboptimal prescribing practices with minimal structured review; insufficient engagement with substance use disorder despite clear indicators; and failure to recognize escalating risk despite multiple concerning incidents. The Department of Communities and Justice failed to maintain adequate contact during a critical period, particularly during a poorly managed caseworker handover. While the homicide-suicide could not have been predicted, earlier multidisciplinary coordination, more robust psychiatric oversight including consideration of specialist referral, and better child protection engagement might have provided opportunity for intervention.

Contributing factors

  • inadequate communication between treating psychiatrist and general practitioner
  • suboptimal psychiatric prescribing practices with incremental dose increases without structured review
  • benzodiazepine dependence on Alprazolam at toxic levels
  • concurrent opioid prescription (Tramadol) without specialist coordination
  • substance use disorder not adequately addressed in psychiatric treatment
  • failure of child protection services to maintain close contact during critical escalation period
  • poorly managed caseworker handover without proper transfer of critical concerns
  • failure to engage Seth's father as protective factor
  • inadequate engagement with mental health provider in child safety planning
  • multiple precipitating stressors in final weeks: housing instability, eviction, family court proceedings, relationship trauma
  • sexual assault by intimate partner precipitating trauma reaction
  • acute intoxication on final day
  • fear of child removal driving concealment of problems from authorities

Coroner's recommendations

  1. Review practice advice for DCJ staff including Mental Health Practice Kit and guidance for funded providers to enhance collaboration skills with mental health providers
  2. Develop standardised after-hours voicemail message on caseworkers' mobile phones with emergency contact information
  3. Incorporate practice guidance about mobile phone use into orientation of new caseworkers
  4. Review existing mandate for transfer of cases between teams to enhance best practice principles, including identifying urgent and high-risk concerns and timescales for new caseworker meeting families
  5. Lifeline to consider technological response options to short/incomplete calls (callback, text message, or automatic welfare check referral)
