AI-generated summary
Matthew Keith Constantine, aged 33, died from hypoxic-ischaemic encephalopathy following a hanging attempt while under home detention. He was released from prison in December 2021 with parole conditions including electronic monitoring and curfew. Following relationship difficulties, arrest of his girlfriend, and a miscarriage, he experienced acute emotional distress. On 18 March 2022, after his girlfriend blocked contact, he posted suicide threats on social media and hanged himself. Police attended within 28 minutes and initiated resuscitation, achieving return of spontaneous circulation. However, he suffered severe hypoxic brain injury and was declared brain dead on 20 March 2022. The coroner made no recommendations. Key clinical lesson: early identification and intervention for acute suicidal ideation in recently released prisoners with substance use disorders and relationship crises may improve outcomes.
