According to the suit, which was filed last week, Officer Allyson Bogdalek confessed to Cook County State's Attorneys that she committed perjury, destroyed evidence, and conspired with her partner, Officer Dominick Catinella, in the criminal case of State of Illinois v. Ranceallen Hankerson.

Despite the confession of perjury, a felony punishable by a maximum of five years in prison, the Cook County State's Attorneys' office refused to prosecute Bogdalek.

Catinella, who admitted to intentionally destroyed evidence, a felony punishable by up to eight years in prison, was also not prosecuted.

The lawsuit says prosecutors from the Cook County State's Attorney's Office sought to prosecute in connection with this incident, but Cook County State's Attorney Anita Alvarez personally intervened and prevented any charges from moving forward.
