The Criminal Investigations Division (CID) is the investigative branch of the police department, performing all criminal investigations and working closely with both the Collin County and Denton County District Attorney's Offices 
to prosecute all criminal cases.
CID is currently authorized at one lieutenant, three sergeants, and 18 detectives. Detectives assigned to the division are police officers who have been specially selected and trained, and who commit to a minimum of two years assigned to the division.
Once a case is received by the Criminal Investigations Division, it is assigned to one of three investigative groups: Crimes Against Persons (CAPERS), Property Crimes, or the Special Investigations Unit (SIU). Cases are assigned based on the elements of the offense and the investigative focus required by the investigators.
