Wisconsin Dept. of Justice
Division of Criminal Investigation
The Division of Criminal Investigation (DCI) investigates crimes that are statewide in nature or importance. DCI special agents work closely with local officials to investigate and prosecute crimes involving arson, financial crimes, illegal gaming, computer crimes, drug trafficking, government corruption, and crimes against children. Upon request, the Division assists local law enforcement agencies in cases involving homicides and multi‑jurisdictional theft or fraud. The Division also performs special investigations requested by the Governor or the Legislature. The Division is organized into bureaus and units, based on specialized investigative needs: the Arson Bureau and Special Assignments Bureau; the Gaming Bureau; the Investigative Services Bureau (which includes the Technical Services Unit, the Analytical Services Unit, the Wisconsin Clearinghouse for Missing and Exploited Children and Adults and the Wisconsin Statewide Information Center); the Narcotics Bureau; and the Public Integrity Bureau (which includes the Computer Crimes Unit, the Financial Crimes Unit and the Internet Crimes Against Children (ICAC) Task Force Unit.)
