CHICAGO — A onetime Chicago cop is suing his old bosses for defamation, alleging they bad-mouthed him after he sought post-retirement work as a federal court security officer.
Donald J. Petersen Jr. was a nearly 40-year veteran of the Chicago Police Department, retiring from the force in 2009 and shortly after applying for a position with the U.S. Marshal's office in Chicago's Dirksen Federal Building, according to the lawsuit filed Monday in Cook County Circuit Court.
