AI-generated summary

Two Aboriginal teenagers, Trisjack Simpson (17) and Christopher Drage (16), drowned in the Swan River while attempting to swim across to evade police pursuit on 10 September 2018. Both had recently ingested cannabis. The youths made a dangerous and spontaneous decision to enter the water when they reached the riverbank during a foot pursuit by two junior police officers investigating suspected trespassing/burglary. Though the police officers' actions in commencing and continuing the pursuit were lawful and appropriate, the coroner found systemic issues: inadequate supervision of junior officers partnering together, insufficient induction regarding significant geographical features of operational areas, and poor relationships between police and Aboriginal youth. The tragic outcome reflects broader marginalisation of Aboriginal youth and historical distrust of police. Tactical operators who attempted rescue demonstrated extraordinary bravery in treacherous conditions but could not prevent the drowning. The cannabis may have marginally increased drowning risk through impaired judgement, but the primary cause was the dangerous decision to swim during high-risk water conditions while fleeing police.

Coroner's recommendations

  1. Western Australian Police Force should introduce a policy that, whenever possible, probationary constables performing operational duties should be partnered with a police officer with at least one year post-probationary operational experience
  2. All police officers with operational duties in a defined area should receive an induction upon being posted to the area that includes identification of boundaries and significant physical, demographic, cultural and socioeconomic features of that area
  3. Newly promoted 1st class constables and senior constables at metropolitan and regional police stations should undertake immersive, face-to-face cultural awareness training to enhance relationships between police and Aboriginal people
