S.C. Code Ann. § 20-7-650
(C) Within twenty-four hours of the receipt of a report of suspected child abuse or neglect or within twenty-four hours after the department has assumed legal custody of a child pursuant to Section 20-7-610(F) or (G) or within twenty-four hours after being notified that a child has been taken into emergency protective custody, the department must begin an appropriate and thorough investigation to determine whether a report of suspected child abuse or neglect is "indicated" or "unfounded". The finding must be made no later than forty-five days from the receipt of the report. A single extension of no more than fifteen days may be granted by the director of the department, or the director's designee, for good cause shown, pursuant to guidelines adopted by the department. If the investigation cannot be completed because the department is unable to locate the child or family or for other compelling reason, the investigation may be reopened at a later date if the child or family is located or the compelling reason for failure to complete the investigation is removed. The department shall make a finding within forty-five days after the investigation is reopened.
This section does not require the department to investigate reports of child abuse or neglect which resulted in the death of the child unless there are other children residing in the home, or a resident of the home is pregnant, or the subject of the report is the parent, guardian, or person responsible for the welfare of another child regardless of whether that child resides in the home.
(G) All reports that are not indicated must be classified as "unfounded". Unfounded reports must be further classified as either Category I, Category II, or Category III.
(H) Reports of child abuse and neglect must be entered immediately into the department's centralized data system in one of four categories: Suspected, Unfounded, Indicated, or Affirmative Determination. If the report is categorized as unfounded, the entry must further state the classification of unfounded report as set forth in subsection (G). All initial reports must be considered suspected. Reports of suspected child abuse and neglect must be maintained for no more than sixty days after the report was received by the department. On or before the expiration of that time, reports must be converted into either unfounded or indicated reports pursuant to the agency's investigation. Upon an affirmative determination, indicated reports must be converted to the category of "affirmative determination".
(I) The names, addresses, and all other identifying characteristics of persons named in all unfounded reports in Category I maintained in department files may be used only for auditing and statistical purposes. All identifying information contained in unfounded reports in Category I must be destroyed immediately after use of the information for auditing and statistical purposes, and in no case later than one year from the date that the last report has been determined to be unfounded; however, all information in the report which is unnecessary for auditing and statistical purposes must be destroyed immediately upon a determination that the report is unfounded, and the remaining information must be kept strictly confidential except for auditing and statistical purposes. If an unfounded report is in Category II or Category III, the report and related information may be retained by the department in its records for one year for use by department staff or law enforcement agencies in relation to child abuse and neglect investigations or proceedings involving the subject of the report or the same child. The department may not use the information in records or entries of Category II or III unfounded reports for any purpose other than child abuse and neglect proceedings involving the same subject or the same child and auditing and statistical purposes. Notwithstanding Section 20-7-690 or any other provision of law, no information contained in unfounded reports may be disclosed under any circumstances, except that:
(2) information in records concerning Category II or III unfounded reports may be disclosed to a law enforcement agency investigating a child abuse or neglect case involving the subject of the report or the same child.
If an unfounded report is in Category I, only information necessary for auditing and statistical purposes may be retained in department records or in the database. As soon as the record has been used for auditing or statistical purposes, it must be destroyed. All identifying information must be deleted from the database immediately upon use of the entry for auditing or statistical purposes. In no case may the record or entry be kept for more than one year from the date that the report was determined to be unfounded. The department may not use the information contained in records or entries of Category I unfounded cases for any purpose other than auditing or statistical purposes. No information contained in the record or the database concerning a Category I unfounded case may be disclosed to any person or entity other than the Department of Child Fatalities pursuant to Section 20-7-5930.
(K) At a hearing pursuant to Section 20-7-736 or 20-7-738, at which the court orders that a child be taken or retained in custody or finds that the child was abused or neglected, the court:
