Case Assignment

Once a case is received by the Criminal Investigations Division, it is assigned to one of 3 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.
