S.C. Code Ann. § 17-7-530

If the body has been so long dead and buried or so injured by improper keeping as that the causes of the death cannot be ascertained upon the examination the coroner shall make a record of the fact, stating its condition, by whom and how long it had been kept or buried, the circumstances of the burial, and the identity, if discovered. Such record shall be entered in his book and returned, as any other inquisition, to the clerk of the court of general sessions for the county.
