Scott William Martin, aged 40, was fatally stabbed in his apartment in Halls Head, Western Australia in January 2017 by Damian Maxfield, who was experiencing a methamphetamine-induced psychotic episode. Maxfield had been apprehended by police following a violent incident at another address approximately 1.5 hours before the murder. Police released him without charge, and he proceeded directly to Martin's residence where he attacked both Martin and his partner. Key clinical lessons: police officers failed to adequately recognise and act on clear signs of acute mental illness (delusions, hallucinations, disordered thought, impulsivity, unregulated emotions). They did not utilise Mental Health Act 2014 powers to apprehend him for assessment. Police communications failures meant attending officers lacked critical safety information about the knife brandished at the earlier address. Supervision of junior constables during the initial investigation was inadequate. Whilst the decision to release from custody may have been legally defensible, the case highlights failures in mental health recognition, risk assessment, and information-sharing systems.
