Coroner

n. official examiner that investigates unnatural deaths

A coroner is either the presiding officer of a special court, a medical officer, or an officer of law responsible for investigating deaths, particularly those happening under unusual circumstances.In some countries, coroners have additional investigatory roles. For example, in the United Kingdom under the Treasure Act 1996 a coroner will determine the most likely manner in which treasure came to be in the place where it was found (whether it was lost or hidden) which will determine the legal entitlements to the treasure trove.
