Sec. 9. AUTOPSY. (a) If the cause of death shall be determined beyond a reasonable doubt as a result of the investigation, the medical examiner shall file a report thereof setting forth specifically the cause of death with the district attorney or criminal district attorney, or in a county in which there is no district attorney or criminal district attorney with the county attorney, of the county in which the death occurred. If in the opinion of the medical examiner an autopsy is necessary, or if such is requested by the district attorney or criminal district attorney, or county attorney where there is no district attorney or criminal district attorney, the autopsy shall be immediately performed by the medical examiner or a duly authorized deputy. In those cases where a complete autopsy is deemed unnecessary by the medical examiner to ascertain the cause of death, the medical examiner may perform a limited autopsy involving the taking of blood samples or any other samples of body fluids, tissues or organs, in order to ascertain the cause of death or whether a crime has been committed. In the case of a body of a human being whose identity is unknown, the medical examiner may authorize such investigative and laboratory tests and processes as are required to determine its identity as well as the cause of death. In performing an autopsy the medical examiner or authorized deputy may use the facilities of any city or county hospital within the county or such other facilities as are made available. Upon completion of the autopsy, the medical examiner shall file a report setting forth the findings in detail with the office of the district attorney or criminal district attorney of the county, or if there is no district attorney or criminal district attorney, with the county attorney of the county.
