AS 12.65.020 provides that the state medical examiner may perform a post-mortem examination, including an autopsy, necessary to make a proper determination of the cause of death and to complete the death certificate, when a death occurs in any of a variety of enumerated circumstances, or when the medical examiner feels the circumstances warrant investigation. The medical examiner must prepare a report of findings and conclusions to the coroner, to assist in determining whether to order an inquest. The medical examiner's investigative report is privileged and confidential, and not subject to disclosure pursuant to AS 40.25.
