A coroner is a government official who is empowered to conduct or order an inquest into the manner or cause of death, and to investigate or confirm the identity of an unknown person who has been found dead within the coroner's jurisdiction. In medieval times, English coroners were Crown officials who held financial powers and conducted some judicial investigations in order to counterbalance the power of sheriffs. The word coroner derives from the same source as the word crown, and it is believed to denote an officer of the Crown.
