A 22-year-old university student with recent substance use presented to ED following violent behaviour. He had facial trauma with mild head injury and abnormal metabolic parameters. Initial management appropriately prioritized medical assessment and resuscitation before mental health evaluation. He was sedated and restrained for acute agitation, with restraints removed after 3 hours when settled. During morning shift, he appeared compliant and cooperative. Two code greys were called after he attempted to leave; during the second incident, he became physically aggressive and left ED before additional security arrived. He was found drowned shortly after. The coroner found management reasonable despite delayed mental health assessment—medical stabilization was necessary first. Key lessons: ensure early mental health referral once patient is coherent, provide sufficient security resources in ED, and avoid delayed assessments waiting for family presence when safety risks are present.
