A former county elections administrator in North Carolina faces charges that he altered the number of votes cast during a primary election last year.

A Durham County grand jury on Monday indicted 59-year-old Richard Rawling of Cary for felony obstruction of justice and a misdemeanor charge of failure to discharge his official duties. Calls to his home were not answered.

The Durham County elections board said last fall more than 1,000 provisional ballots were likely mishandled during the March 2016 primary election, but the miscount didn't affect the primary's outcome.

State elections board officials said Monday there was no evidence Rawling altered ballot counts to support a particular political party or candidate. The state board's investigation of last November's general election results found no other examples of administrative fraud.
