More than 3,700 early votes cast in a southwestern Indiana county during the 2012 general election went uncounted because of an error by an electronic voting machine technician, officials said Monday.
The Warrick County Election Board reported the error resulted in 3,791 votes going uncounted.
County Clerk Sarah Redmon told the Evansville Courier & Press the error resulted in only 10 percent of in-person, early votes.
Kevin Derr, Democratic chairman for the county east of Evansville, said the problem was discovered by a Democratic precinct leader who recently was cross-referencing precinct summary reports with a state voter history report.
The precinct leader found precinct summary reports of tallied machine and paper votes for Warrick County were 3,700 votes less than the state report, compiled by manually entered voting records, Derr said.
Indianapolis-based MicroVote General Corp., which services the county's electronic voting machines, found that one of their technicians incorrectly uploaded early votes, Derr said.
