Criminal Investigations Division

The Criminal Investigations Division includes multiple units that complement not only each other, but also serve to complement, assist, and support the Patrol Division of the Department. The units within the Division include the following:

  • Detective Commander
  • General Assignment Detectives
  • School Resource Officer/Juvenile Detectives
  • Detective assigned to the North Central Narcotics Task Force
  • Inventory/Evidence/Property Custodian
  • Administrative Assistant.

    In addition to normal tasks and caseloads assigned to the General Assignment Detectives, each is assigned an alternate specialty in the area of criminal investigations. These specialties include Criminal Intelligence, Computer Crimes and Child Exploitation/Pornography, Sex Offender Registration and compliance, Gang Crime Specialist, and Problem Oriented Policing and Technology.

    The Sex Offender Registration Program is aggressively monitored and controlled. This has led to several arrests of St. Charles sex offenders for non-compliance, and with the implementation of new and improved State laws, each offender is now required to register up to four times per year.

    The Evidence/Property Custodian function is a multi-facetted one; the responsibility for maintaining integrity of all found items or submitted evidence is combined with the coordination of future investigative, crime lab submission or court related needs. Given all variables involved, we continually strive in advance to be prepared to deal with an unlimited array of items. Utilizing our own small crime laboratory, equipped with specialized equipment, we are able to process many different types of submitted evidence here locally.
