MADISON, Wis. (AP) — An Illinois man has filed a federal lawsuit alleging an off-duty police officer improperly put his knee into his 12-year-old daughter’s neck during a fight in a Wisconsin middle school last year. Jerrel Perez, of Zion, Illinois, filed the lawsuit Monday in federal court in Milwaukee against the officer, Shawn Guetschow, the city of Kenosha and its school district. Perez alleges that Guetschow used excessive force when he broke up a fight between his daughter and another student last March and restrained his daughter by putting his knee on her neck. The city attorney said the city hadn’t been served yet. An attorney for Guetschow and the school district promised to mount a vigorous defense.
