Oelwein residents will head to the polls next week to vote for a new mayor. Four candidates are running for mayor, including Ryan DeHaven, June Griffith, Brandon Kieffert and Peggy Sherrets. The Oelwein City Council had appointed Sherrets as acting mayor last month to replace Mayor Jason Manus. Manus resigned in August after he was chargd with sexually abusing two girls several years ago. The candidates participated in a forum at Oelwein Middle School Wednesday night. The special election will take place Tuesday from noon to 8 pm at the Oelwein Community Plaza.
