Tyler Cassidy, a 15-year-old boy, was fatally shot by Victoria Police on 11 December 2008 during a mental health crisis. He had stolen two large kitchen knives from Kmart and made threatening statements, explicitly demanding police shoot him. Police attempted verbal commands, OC foam spray, warning shots, and leg shots before LSC Dods fired lethal shots at Tyler's chest as Tyler continued advancing with knives after multiple failed de-escalation attempts. Tyler had a history of oppositional defiant disorder, anger management issues, recent grief over his father's death, and alcohol use that evening. The coroner found no single preventable failure but noted shortfalls in operational safety training, communication between responders, and investigation procedures. Key lessons include improved recognition of mental health crises in young people, better police training on vulnerable youth, and more robust investigation models for police-involved deaths.
