Grillo, Carl Antony

42y · Male·Combined effects of moderately severe physical exertion; a lateral vascular neck restraint and restraint in a prone position; and a high level of amphetamine toxicity on a background of myocardial fibrosis and coronary artery atheroma. Mechanism: cardiac arrhythmia secondary to hypoxic-ischemic injury.

Carl Grillo, a 42-year-old man, died after police detained him during a foot chase in Spring Hill, Brisbane. Following an initial wrestling struggle, a lateral vascular neck restraint was applied by Senior Constable Jakes for approximately three 10-second intervals. The coroner found Mr Grillo was not placed in recovery position as promptly as training dictated, remaining prone for several minutes post-restraint. Medical evidence established that death resulted from combined factors: severe physical exertion, neck restraint, prone restraint positioning, and high amphetamine toxicity (1.2 mg/kg) against background myocardial fibrosis and coronary artery disease. While the officers' force was found justified and reasonably necessary, the coroner identified that prompt placement in recovery position following restraint application, consistent with training on positional asphyxia risks, would have been best practice. The failure to maintain recovery position contributed to an unnecessarily increased risk of hypoxic-ischemic injury.
