A domestic abuse victim filed a lawsuit Friday claiming a disgraced Wisconsin prosecutor violated her constitutional rights by sending her text messages seeking to start an affair while prosecuting her ex-boyfriend.

The lawsuit filed on behalf of Stephanie Van Groll, 26, alleges former Calumet County District Attorney Ken Kratz’s behavior was sexually harassing, discriminating and part of a pattern dating back years. It claims her right to equal protection under the U.S. Constitution was violated and seeks unspecified damages.
