W. Va. Code § 3-1-51

(a) The clerk of the county commission shall cause a letter to be mailed by first class mail to each voter who executed a voter identity affidavit pursuant to section thirty-four of this article. The letter shall be mailed within sixty days after the election. The clerk shall mark the envelope with instructions to the United States Post Office not to forward the letter and to provide address correction information. The letter shall notify the addressee that a person who did not present a valid identifying document voted using his or her name and address and instruct the addressee to contact the clerk immediately if he or she did not vote. The letter shall also inform the addressee of the procedure for obtaining an identification card from the Division of Motor Vehicles for voting purposes.

(b) The clerk of the county commission shall cause letters mailed pursuant to subsection (a) of this section that are returned as undeliverable by the United States Post Office to be referred to the Secretary of State. The clerk shall also prepare and forward to the Secretary of State a list of all persons who were mailed letters under subsection (a) of this section and who notified the clerk that they did not vote. Upon receipt of notice from a person who receives a letter mailed pursuant to subsection (a) of this section that the person did not vote, or upon receipt of a referral from the clerk, the Secretary of State shall cause an investigation to be made to determine whether fraudulent voting occurred. Beginning July 1, 2019 and each year thereafter, the Secretary of State shall submit a report to the Joint Committee on the Judiciary and the Joint Committee on Government and Finance detailing the results of all investigations of voter identity affidavits, including, but not limited to, the number of investigations, the number of ballots cast, and the number and results of any determinations made regarding fraudulent voting.
