S.C. Code Ann. § 17-21-20: Venue where person causes injury in one county and death occurs in another.

When any person shall be struck, wounded, poisoned or otherwise injured in one county and dies thereof in another any inquisition or indictment thereon found by jurors of either county shall be as good and effectual in law as if the stroke, wound, poisoning or other injury had been committed and done in the county in which the party shall die. And the person guilty of such striking, wounding, poisoning or other injury and every accessory thereto, either before or after the fact, shall be tried in the county in which such indictment shall be found and, if convicted, punished in the same mode, manner and form as if the deceased had suffered such striking, wounding, poisoning or other injury and death in the county in which such indictment shall be found.
