S.C. Code Ann. § 23-3-625: DNA samples of missing persons.

Family members of a missing person may submit DNA samples to the State Law Enforcement Division (SLED). If the person is missing thirty days after a missing person report has been submitted to the Missing Person Information Center, SLED must conduct DNA identification, typing, and testing on the family members' samples. SLED may, within its discretion, conduct DNA identification, typing, and testing on the family members' samples prior to thirty days if SLED determines that such DNA identification, typing, and testing is necessary. If SLED does not have the technology necessary for a particular method of DNA identification, typing, or testing, SLED may submit the DNA samples to a Combined DNA Indexing System (CODIS) laboratory that has the appropriate technology. The results of the identification, typing, and testing must be entered into CODIS.
