Mississippi Code Title 41. Public Health § 41-61-67

(1) In any case of death where the body is or has been buried without investigation by a medical examiner as to the cause and manner of death, or where sufficient cause develops for further investigation after a body has been buried as determined by a medical examiner, the State Medical Examiner shall authorize an investigation and send a report of the investigation with recommendations to the appropriate district attorney. The district attorney may forward the report to the circuit court having jurisdiction of the matter and petition the court for disinterment. The circuit judge may order that the body be exhumed and that an autopsy be performed by the State Medical Examiner. A report of the autopsy and other pathological studies shall be delivered to the judge. However, in cases of suspected homicide, the State Medical Examiner shall be able to authorize disinterment for the purposes of autopsy. The cost of the exhumation, autopsy, transportation and disposition of the body shall be paid by the county for which the service is provided.

(2) Any person may petition the circuit court for an order of exhumation. Upon a showing of sufficient cause, the court may order the body exhumed. The cost incurred shall be assigned to the petitioner.
