S.C. Code Ann. § 9-9-100
(4) Upon receipt of proof, satisfactory to the board, of the death, after June 30, 1969, of a member of the system then in service as a member of the General Assembly who had completed at least one full year of membership in the system or of the death of an in-service member as a result of an injury arising out of and in the course of the performance of his duties regardless of length of membership, there must be paid to the person he nominated for the refund of his accumulated contributions, unless he has nominated a different beneficiary by written designation filed with the board, pursuant to Section 9-9-90, if the person is living at the time of the member's death, otherwise to the member's estate, a death benefit equal to the annual earnable compensation of the member at the time his death occurs. The death benefit is payable apart and separate from the payment of the lump sum amount, or the allowance in lieu of it, pursuant to subsections (1) and (3). For purposes of this subsection, a member is considered to be in service at the date of his death if his last day of earned service credit as a member of the General Assembly occurred not more than ninety days before the date of his death and he has not retired or withdrawn contributions.
The Board is authorized to take such action as may be necessary to provide the death benefit under this section in the form of group life insurance upon a determination that to do so would guarantee a more favorable tax treatment of the benefit to beneficiaries to whom such benefit is payable.
Upon the death of a retired member on or after July 1, 1985, there must be paid to the designated beneficiary or beneficiaries, if living at the time of the retired member's death, otherwise to the retired member's estate, a death benefit of one thousand dollars if the retired member had ten years of creditable service but less than twenty years, two thousand dollars if the retired member had twenty years of creditable service but less than thirty, and three thousand dollars if the retired member had at least thirty years of creditable service at the time of retirement.
