MITCHELL, S.D. (AP) - A 54-year-old Mitchell resident accused of voting twice in last month's school board election has pleaded not guilty.

KORN radio reports that a trial date was set for the week of Aug. 20.

Craig Guymon was arrested on voter fraud charges a day after the June 4 election. Guymon is known in the South Dakota town for being a vocal critic of school officials.

Authorities said Guymon voted that morning at the Mitchell Career and Technical Education Academy and later returned an absentee ballot to the Davison Auditor's Office at the county courthouse.

The charge is a felony carrying a maximum penalty of two years in prison and a $4,000 fine.

Guymon had previously run for the school board on multiple occasions but was not a candidate in the election.
