BUFFALO -- The Wright County Attorney's Office has completed its investigation of 30 people suspected of voter fraud.

Wright County Attorney Tom Kelly says five of the 30 have been formally charged with fraud for voting while on felony probation.

Three people were charged with fraud from the the 2008 election and two were charged from the 2010 election.

No charges will be filed against the remaining 25 people because the allegations were proven to be unfounded.
