Larry Massey was sentenced to five years in Benton County Circuit Court Tuesday, but had three years suspended. He will also serve two years on probation.
Attorney General Jim Hood says Massey had entered into a plea deal in return for testifying against his co-defendants, but then changed his testimony while on the stand. A grand jury indicted him in March on two counts of perjury.
He had pleaded guilty in 2008 to his role in an alleged vote-buying scheme. He was among 16 people arrested in the case involving 2007 elections.
So far, two defendants have been convicted by a jury and sentenced. Seven others have pleaded guilty, but are awaiting sentencing. The remaining seven are awaiting trial.
