The Division of Criminal Investigation (DCI) is charged with investigating crimes of statewide nature, importance or influence. DCI employs sworn law enforcement officers with statewide jurisdiction. DCI Special Agents and criminal analysts work closely with local, county, tribal, state, and federal law enforcement officials to investigate and prosecute a broad array of crimes, including homicide, arson, financial crimes, illegal gaming, multi-jurisdictional crimes, drug trafficking, internet crimes against children, human trafficking, sexual assault, cybercrimes, homeland security, public integrity, and government corruption. DCI also provides focused management of officer-involved death investigations, bringing extensive experience and added confidence to investigations involving use of force by law enforcement that results in death. In addition, DCI provides extensive training to local, state and federal officers on current issues in law enforcement.
DCI has regional field offices in the areas of Madison, Milwaukee, Appleton, Eau Claire, and Wausau. Additionally, DCI works in partnership with other law enforcement agencies at the North Central High Intensity Drug Trafficking Area (HIDTA) office in Milwaukee, the Lake Winnebago Area Metropolitan Enforcement Group – Drug Unit, the Native American Drug and Gang Initiative, as well as other state and federal task forces.
The
Wisconsin Statewide Intelligence Center (WSIC) is one of two fusion centers in Wisconsin. WSIC serves as the primary focal point for threat information sharing among federal, state, local and tribal law enforcement, emergency management, fire service, public health, corrections, military and private sector partners for the state. WSIC criminal intelligence analysts provide analysis and specialized investigative and tactical intelligence support to enhance the efforts of DCI and other law enforcement agencies in Wisconsin. Analysts provide investigative support by identifying suspects, developing investigative leads, examining patterns of criminal activity, gathering and examining records, and defining the roles of participants in criminal organizations to support prosecutions.
DCI manages the Wisconsin Anti-Human Trafficking Task Force, which combines law enforcement with victim advocate groups to combat human trafficking using a victim-centered approach. Human trafficking investigations involve cases of sexual exploitation and/or labor trafficking.
Wisconsin's
ICAC (Internet Crimes Against Children) Task Force formed in 1999 and is a partnership with local law enforcement agencies. DCI ICAC personnel provide investigative and prosecutorial assistance statewide, as well as training to law enforcement, prosecutors, and the public.
The
State Fire Marshal's Office conducts investigations of fires and explosions to determine origin and cause. As Deputy State Fire Marshals, Special Agents use scientific methods to conduct investigations of fires and explosions and classify these events as accidental, natural, incendiary, or undetermined.
Digital Evidence Unit (DEU) staff aid department investigators and local law enforcement agencies by analyzing electronic media and devices using complex forensic and analytical software systems to identify and present evidence of crimes.
DCI manages Wisconsin's AMBER, Silver, and Green Alert programs, the Wisconsin Clearinghouse for Missing and Exploited Children and Adults, and Wisconsin Crime Alert Network.
