What title does the person who investigates the cause of death?

Answer 1

A coroner or forensics examiner is an official chiefly responsible for investigating deaths, particularly some of those happening under unusual circumstances, and determining the cause of death. Depending on the jurisdiction, the coroner may adjudge the cause himself, or act as the presiding officer of a special court (a "coroner's jury") To become a coroner in England and Wales the applicant must be a lawyer or doctor of at least five years standing. This reflects the role of a coroner, to determine the cause of death of a deceased in cases where the death was sudden, unexpected, occurred abroad, was suspicious in any way or happened while the person was under the control of central authority (e.g., in police cells). Aside from the usual coroners, certain persons are ex officio coroners in limited circumstances-for example the Lord Chancellor has been historically allowed to certify the death of someone killed in rebellion.
