Following an inquest, there is no such thing as a "coroner's report", in the sense of a structured narrative setting out what happened.Under the Home Office Circular 250/1967, a schedule of destruction of coroners records is laid down. While they are within the definition of public records and open to the public after 75 years many will not have survived those 75 years. Once 15 years old the records can be weeded,' that is destroyed or sampled by the individual coroner concerned.See http://www.kcl.ac.uk/depsta/law/research/coroners/records.html about coroner's recordsA newspaper report is the best bet.Stan
