S.C. Code § 14-7-1680
The clerk of the state grand jury, upon the request of the Attorney General or his designee, shall issue subpoenas or subpoenas duces tecum to compel individuals, documents, or other materials to be brought from anywhere in this State to a state grand jury. In addition, a state grand jury may proceed in the same manner as provided by the subpoena rules of the South Carolina Rules of Civil Procedure and Sections 19-9-10 through 19-9-130, except where either is inconsistent with the provisions of this article; provided the subpoena rules of the South Carolina Rules of Civil Procedure and Sections 19-9-10 through 19-9-130 are not considered a limitation upon this section, but supplemental thereto. The subpoenas and subpoenas duces tecum may be for investigative purposes and for the retention of documents or other materials so subpoenaed for proper criminal proceedings. Any law enforcement officer with appropriate jurisdiction is empowered to serve these subpoenas and subpoenas duces tecum and receive these documents and other materials for return to a state grand jury. Any person violating a subpoena or subpoena duces tecum issued pursuant to this article, or who fails to fully answer all questions put to him before proceedings of a state grand jury where the response thereto is not privileged or otherwise protected by law, including the granting of immunity as authorized by Section 14-7-1760, may be punished by the presiding judge for contempt. To this end, where the violation or failure to answer is alleged to have occurred, the Attorney General or his designee may petition the presiding judge to compel compliance by the person alleged to have committed the violation or who has failed to answer. If the presiding judge considers compliance is warranted, he may order this compliance and may punish the individual for contempt where the compliance does not occur.
The clerk of the state grand jury also may issue subpoenas and subpoenas duces tecum to compel individuals, documents, or other materials to be brought from anywhere in this State to the trial of any indictment returned by a state grand jury or the trial of any civil forfeiture action arising out of an investigation conducted by a state grand jury.
