Her Majesty's Coroner announced on September 12 that "The cause of death is not natural. However, we wish to reserve the cause of death at this time pending the toxicologist examination and report for confirmation of cause of death. Friday is the likely release date for the autopsy and toxicology report." "The inquest would happen late October or early November to determine how, when and by what manner Daniel came to his death. All persons who are relevant witnesses, like his mother and hospital staff and airline personnel who had contact with him, would have to testify."
