CROGHAN — The village mayor has decided to step down, and his successor likely will be determined by write-in votes.

Mayor Glen A. Gagnier decided not to run for re-election after six years at the village helm.

And, since no other village residents filed a nominating petition, voters in Tuesday's village election will have to write in their favored candidates for the four-year mayoral seat.

At least one trustee slot also will be determined through write-in votes. Trustee William Shambo is the lone candidate on the ballot for two open four-year trustee seats, since Trustee David Nuffer did not file a nominating petition for re-election.

Victorious candidates may decline their positions. If so, village trustees could fill any vacancies by appointment, said Elaine McLear, Lewis County's Democratic election commissioner.

Mr. Gagnier, a past trustee, was appointed mayor in January 2002 after Mayor James A. Zehr stepped down to accept a job as maintenance director of the village's water and sewer systems. He ran unopposed in 2004.

Constableville voters will have a contested race. Robert Greene, Carol Czajka and Zack Wilton are running for two open trustee seats.

Six other Lewis County villages have uncontested races:
