The Criminal Investigation Division (C.I.D.) is the investigative arm of the police department, consisting of major case investigations, narcotics investigations, the Property and Evidence Unit, criminal investigations, and crime analysis. The Division is lead by Captain Nathan Anderson
The primary function of the Criminal Investigation Division is to review and investigate reports of felony and misdemeanor criminal acts, identify suspects, both adult and juvenile, and prepare cases for prosecution with the U.S., District, County, and City Attorneys' offices. Investigative work is re-active, from reports with the identification, arrest and prosecution of suspects, and also pro-active, through the prevention of criminal acts in their identification of suspects.
C.I.D. also provides support to victims of crimes during the course of an investigation. Crime victims and the community both benefit from the prosecution and punishment of criminals. Many investigations can be completed in a matter of weeks, whereas other investigations may take years before they are solved. Every attempt is made to prioritize their work so that cases involving injured persons, threats to personal safety, and significant property loss receive the most immediate attention. C.I.D. has at least one detective designated as being "on call" at all times, but all detectives may be called in to work major crime scenes when needed.
