Criminal Investigations Division

Detective Section
Detectives follow up on crimes, especially violent felonies, where the offender was not apprehended by first responders. Detectives bring coordinated plainclothes resources to bear on difficult problems like homicides, death investigations, auto theft rings, burglaries, robberies, arsons, sex crimes, threats to public officials, and crimes against vulnerable persons (such as financial exploitation of the elderly).

Crime Scene Investigators / Crime Scene Processing
Investigators from the Crime Scene Investigator (CSI) Unit process crime scenes; collect and submit evidence for testing, such as fingerprints and DNA; and perform morgue runs for death investigations.

Crime Scene Investigators produce high-precision crime scene reconstructions (such as murder scenes) using the new FARO high-precision 3-D laser scanning equipment.

Crime scene investigator (CSI) services are provided to dozens of Cook County suburban municipalities.

Specialized Services
The various components of the Criminal Investigations Division assist a wide variety of outside agencies, including the provision of polygraph operators, police sketch artists, and accident reconstructionists.
