Finding into death of Anthony Laurence Parisi

39y · Male·Multidrug toxicity (GHB, methylamphetamine, ketamine) in a setting of restraint and moderate coronary artery atherosclerosis

Anthony Parisi, 39, died from multidrug toxicity (GHB, methamphetamine, ketamine) in a setting of police restraint and moderate coronary artery atherosclerosis. He consumed large quantities of GHB and methamphetamine on 8 March 2025, presented with acute behavioural disturbance requiring police care and control under mental health legislation. Paramedics appropriately administered ketamine sedation following clinical guidelines, but shortly after, Anthony developed respiratory arrest and cardiac dysrhythmias requiring prolonged resuscitation. The coroner found police restraint was lawful, proportionate and reasonable; paramedics followed appropriate clinical protocols; and no actionable prevention opportunities were identified as Anthony repeatedly declined drug treatment despite multiple hospitalisations.
