Detective Bureau



The O’Fallon Detective Bureau, or Criminal Investigations Division as it’s officially known, is staffed by 17 detectives, two full-time evidence custodians and one civilian clerk. In addition to two supervisors, eight criminal investigators act as general assignment detectives when it comes to day to day investigations.


Several of the eight detectives also have sub-specialties such as fraud, identity theft, and sex crimes. Two detectives are also assigned to the Warrant Office, which works with O’Fallon’s Municipal Court in tracking down municipal fugitives.


The Bureau is responsible for conducting follow-up investigations initiated by the Patrol Division and maintaining a case load of self-initiated complaints.


When should I call the Detective Bureau?

  • When you have questions about the status of a case.
  • When you have new or additional information about a case which has already been reported to the Police Department.
  • When you are looking for advice on matters which may be criminal in nature.

If you call the Detective Bureau during regular business hours (7:00A to 9:00P) your call will be directed to the appropriate detective or supervisor. If the person is not available, messages can be left on the detectives' voice mail for a return call when they're available.

In emergencies or during situations that are in progress, dial 9-1-1.
