(725 ILCS 5/115-5.1) (from Ch. 38, par. 115-5.1)
    Sec. 115-5.1. In any civil or criminal action the records of the coroner's medical or laboratory examiner summarizing and detailing the performance of his or her official duties in performing medical examinations upon deceased persons or autopsies, or both, and kept in the ordinary course of business of the coroner's office, duly certified by the county coroner or chief supervisory coroner's pathologist or medical examiner, shall be received as competent evidence in any court of this State, to the extent permitted by this Section. These reports, specifically including but not limited to the pathologist's protocol, autopsy reports and toxicological reports, shall be public documents and thereby may be admissible as prima facie evidence of the facts, findings, opinions, diagnoses and conditions stated therein.
    A duly certified coroner's protocol or autopsy report, or both, complying with the requirements of this Section may be duly admitted into evidence as an exception to the hearsay rule as prima facie proof of the cause of death of the person to whom it relates. The records referred to in this Section shall be limited to the records of the results of post-mortem examinations of the findings of autopsy and toxicological laboratory examinations.
    Persons who prepare reports or records offered in evidence hereunder may be subpoenaed as witnesses in civil or criminal cases upon the request of either party to the cause. However, if such person is dead, the county coroner or a duly authorized official of the coroner's office may testify to the fact that the examining pathologist, toxicologist or other medical or laboratory examiner is deceased and that the offered report or record was prepared by such deceased person. The witness must further attest that the medical report or record was prepared in the ordinary and usual course of the deceased person's duty or employment in conformity with the provisions of this Section.
