AI-generated summary

Robert Hamish Duncan, a 78-year-old man with a long history of schizophrenia, disappeared on 12 April 2021 from Oxford Street, Sydney. He was last seen at a bus stop at 9:40pm. Despite extensive police investigation including CCTV review, media appeals, and inquiries across multiple jurisdictions, his whereabouts could not be established. The coroner determined on the balance of probabilities that he is deceased, but insufficient evidence exists to determine the date, place, cause, or manner of death. Clinical lessons include the importance of recognising cognitive decline (possible early dementia noted by associates) and ensuring adequate social support systems for vulnerable individuals with chronic mental illness living in the community.
