A disgraced former Rock County jailer is seeing what its like on the other side of the law. 22-year-old Mitchell R. Wellnitz Monday morning waived his right to a preliminary hearing on charges of theft and misconduct in public office. Court Commissioner Larry Barton also entered a not guilty plea for Wellnitz, who stood mute. A criminal complaint accuses Wellnitz of pawning a ring and necklace for $700. Wellnitz was fired from the sheriff’s office, and is free on a signature bond.
