Mississippi Code Title 41. Public Health § 41-37-9

A circuit judge, chancellor or county judge of the county or district where a person died or where the body of such deceased person may be or where the mortal stroke or other cause of death occurred, may, in his discretion, either in term time or in vacation, order an autopsy to be performed upon the body of such deceased person (1) upon the petition of a county prosecuting attorney of the county where the person died, or where the body of such deceased person may be at the time or where the mortal stroke or other cause of death occurred, or (2) upon petition of the district attorney of the district where the person died, or where the body of such deceased person may be at the time or where the mortal stroke or other cause of death occurred. In the event that said petition is filed by the county prosecuting attorney or district attorney, it shall contain allegations that the petitioner believes, has reason to believe, or suspects that such deceased person came to his death by some criminal means or agency, or that the cause of justice would be promoted by having an autopsy performed upon the body of such deceased person. Said petition shall be sworn to and shall be filed in the court of the judge or chancellor who makes the order, and shall be docketed by the clerk as are other cases or suits. If the body of such deceased person has already been interred, the petition shall so state, and if an autopsy is ordered, the order shall order the disinterment of such body for such autopsy and shall order any lawful officer of the county where said body may be buried to employ suitable help to disinter said body and to keep it in a suitable place until said autopsy shall have been performed. If there has been no interment of the body of such deceased person, a copy of the order ordering an autopsy upon said deceased shall be served by the sheriff of the county, or any other person authorized to serve process, upon any person who may be found in charge of any funeral home where said body may be, and such funeral home shall hold said body for autopsy. If the body of such deceased person be not found in any funeral home the sheriff of the county where it may be found shall take said body and keep it in a suitable place until said autopsy shall have been performed. If an autopsy is ordered as provided in this section, the petitioner shall immediately secure the services of a qualified person to perform such autopsy.
