The Criminal Investigation Division is responsible for the investigation of major crimes that require more attention and detail than patrol officers can provide. Oversight is provided by the Lieutenant and the Detectives and School Resource Officers are under the direct supervision of the Sergeant. Crimes investigated by detectives include homicide, aggravated assault, sexual assault, robbery, burglary, arson, auto theft, felony theft, and other significant frauds. Detectives are responsible for conducting interviews, gathering evidence, and identifying and apprehending suspects. Detectives also prepare assigned cases for court according to the rules of law and evidence.

Detectives are assigned cases for investigation according to their severity and solvability. Citizens can contact the Lieutenant or the Sergeant if they have questions about the status of a particular case, or when they wish to provide a tip about criminal activity. Citizens should contact the assigned detective when they wish to report additional information about a case that's already under investigation. Citizens who wish to provide anonymous information can also contact Winnebago County Crime Stoppers and may be eligible for a cash reward.
