Criminal Investigation

The Criminal Investigation Division (CID) is the investigative arm of the Police Department. CID handles:

  • Development of information contributing to offense prevention
  • Followup investigations of criminal offenses and internal investigations
  • Management of physical evidence and property
  • Victim assistance

Primary Functions

The primary functions of the Criminal Investigations Division are:

  • Review and investigate reports of felony and misdemeanor criminal acts
  • Identify suspects, both adult and juvenile
  • Prepare cases for prosecution with the District and County Attorney’s Offices

Investigative Work

Investigative work is reactive from reports with the identification, arrest, and prosecution of suspects and also proactive through the prevention of criminal acts in their identification of suspects.

Victim Support

The Investigations Division also provides support to victims of crimes during the course of an investigation. The crime victims and the community both benefit from the prosecution and punishment of criminals.

Investigation Length & Priorities

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.


The Investigation Division has at least one detective designated as being “on call” at all times, but all detectives can be called in to work major crime scenes, when needed. The detectives are available Monday through Friday, 8 a.m. to 5 p.m., and can be contacted by phone, at 214-521-5000.
