If it was suicide then there might be an inquest report.
Official reports of inquests
As inquests are public enquiries, it is possible to obtain a copy of the post-mortem report and any depositions taken at the inquest, including a copy of the verdict. These official reports are only available after the inquest has concluded. There is a small fee for these documents. Inquest papers are not available before the inquest has been held.
You can get copies of official reports of inquests from the local Coroner's office. To get a report, you will need to write to the Coroner's Office requesting this information and include the name of the deceased, the date of death, the hospital involved (if any) and the date of the inquest (if you know this).
