Investigations conducts both criminal and administrative investigations of allegations of corruption, misconduct, waste, or substandard performance by governmental officers, employees, contractors, vendors, and licensees, among others. It conducts these investigations either in response to complaints from City employees or other citizens, or on the Inspector General’s own initiative. In the event of wrongdoing in administrative cases, OIG will issue recommendations for disciplinary action that require a response or final action from the affected City department. In criminal cases, OIG will work with the United States Attorney’s Office or the Cook County State’s Attorney’s Office, which may prosecute these matters. If an investigation reveals misconduct or inefficiencies that are not being addressed by City policy or procedure, OIG may also recommend program or policy changes.
