Election officials say more than a dozen people in Fairfax County voted in both Virginia and Maryland in 2012.
The Virginia Attorney General's Office is investigating allegations of voter fraud in the county, The Richmond Times-Dispatch reported.
The Virginia Voters Alliance identified 17 people who voted in both Fairfax County and various localities in Maryland during the 2012 general election. Fairfax electoral board secretary Brian W. Schoeneman tells the newspaper that in some cases, individuals voted in both states in elections dating back to 2004.
State Board of Elections chairman Charles E. Judd tells the newspaper that election officials have also found dual registration in other localities. But he says officials haven't yet determined whether these individuals voted in both locations.
