Inquest into the passing of Steven Lee Nixon-McKellar

27y · Male·Sudden cardiac arrest in the context of physical and psychological exertion during restraint by police, brief pressure applied to the neck using a Lateral Vascular Neck Restraint, stimulant drug intoxication (methylamphetamine), asthma, bronchopneumonia, and coronary atherosclerosis.

Steven Nixon-McKellar, a 27-year-old First Nations man, died following a physical altercation with Queensland Police officers attempting to arrest him on 7 October 2021. He suffered cardiac arrest during restraint, with the cause determined to be multifactorial: prolonged physical and psychological exertion, police baton pressure across his abdomen, brief lateral vascular neck restraint application, methamphetamine intoxication (1.1mg/L—potentially lethal level), asthma, bronchopneumonia, and coronary atherosclerosis. Medical evidence indicated Steven had extremely compromised physiological reserve. While the LVNR application had temporal proximity to collapse, it was not the sole cause. The coroner found police conduct complied with policies; no criminal charges or disciplinary referrals were warranted. Key clinical lessons: recognise premature chronic disease onset in First Nations populations; understand cardiac vulnerability during stimulant intoxication; appreciate that multifactorial deaths during restraint are often unpredictable and unpreventable.
