S.C. Code § 17-5-280
The medical examiner's office must keep complete indexed records of all deaths investigated, containing all relevant information concerning the death and the autopsy report, if made. Any prosecuting attorney or law enforcement officer may secure copies of these records or information necessary for the performance of his official duties. Copies of such records or information must be furnished upon request to any party to whom the cause of death is a material issue.
Reports of post-mortem examinations, autopsies, copies of records, photographs, laboratory findings, and reports in the office of the county medical examiner when duly attested by the medical examiner or his assistant must be received as evidence in any court or other proceedings for any purpose for which the original could be received without any proof of the official character of the person whose name is signed thereto.
