South Carolina's attorney general has notified the U.S. Justice Department of potential voter fraud.

Attorney General Alan Wilson sent details of an analysis by the Department of Motor Vehicles to U.S. Attorney Bill Nettles.

In a letter dated Thursday, Wilson says the analysis found 953 ballots cast by voters listed as dead. In 71 percent of those cases, ballots were cast between two months and 76 months after the people died. That means they "voted" up to 6 1/3 years after their death.

The letter doesn't say in which elections the ballots were cast.

The analysis came out of research for the state's new voter identification law. The U.S. Justice Department denied clearance of that law.

Wilson told Nettles he asked the State Law Enforcement Division to investigate.
