After the medical examiner's inquiry and inquest have been completed, the dead body shall be delivered to the person legally entitled thereto for burial. If no person claims the body, it shall be turned over to the coroner of the county where death occurred for disposition as provided by law. If the deceased has an estate out of which burial expenses can be paid, either in whole or in part, such estate shall be taken for such purpose before any expense under this Code section is imposed upon any county.
