Investigations Division
The Investigations Division of the West Chicago Police Department has the responsibility of investigating all criminal activity for the arrest and prosecution of the offenders responsible for the crime.
Some of these crimes include but are not limited to: homicides, assaults, robberies, burglaries, thefts, frauds, sexual assaults, sexual related crimes, white collar crimes, missing persons, suspicious deaths, and drug investigations.
Evidence is gathered through witness interviews, interrogations, and physical evidence. An investigation begins the minute the detective steps onto the crime scene. An investigation has the potential of requiring literally hundreds and even thousands of investigative hours. The Investigations Division Commander reviews the daily police reports submitted by the Patrol Officers. The Investigation Division handles over 500 cases per year.

Crime Analysis Unit (CAU)
Crime Analysis is a set of systematic, analytical processes directed at providing timely and pertinent information relative to crime patterns and trend correlations. This information assists operational and administrative personnel in planning the deployment of resources for the prevention and suppression of criminal activities, aiding the investigative process, and increasing apprehensions and the clearance of cases.
There are three analytical functions in a Crime Analysis Unit: Administrative, Strategic, and Tactical.
- Administrative Crime Analysis - deals with long-range comparisons. Examples of administrative crime analysis tasks include providing economic, geographic, and law enforcement information to police management, city hall, city council, and neighborhood/citizen groups.
- Strategic Crime Analysis - is primarily concerned with operational strategies and seeks solutions to on-going problems (weeks, months, quarters or years). The purpose of strategic crime analysis is to perform police service more effectively and efficiently by matching service delivery to demands for service.
- Tactical Crime Analysis - deals with immediate criminal offenses (immediate, hours, days, weeks). It promotes a quick response to recent offenses such as burglaries and robberies. The tactical crime analyst provides information to assist operational personnel in the identification of specific crime trends and in the arrest of criminal offenders.
