In 2019, Wisconsin Watch received a tip about a case. It alleged that the prosecutor, Outagamie County District Attorney Vince Biskupic, had withheld information about a key witness — a young woman who got some help, monetary and otherwise, from the police. That assistance was never disclosed to the defense. It’s part of a pattern seen in some other high-profile cases prosecuted by Biskupic, according to an investigation by Wisconsin Watch and WPR.
