Criminal Investigation Section

The O’Fallon Criminal Investigation Section, or Detective Bureau as it is commonly known, is staffed by 18 commissioned personnel and one civilian employee. In addition to three supervisors, nine criminal investigators act as general assignment detectives when it comes to day-to-day investigations.

Several of the nine detectives also have sub-specialties such as fraud, identity theft and sex crimes.

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

When should I call the Criminal Investigation Section?

  • When you have questions about the status of a case that is assigned to the Criminal Investigation Section.
  • When you have new or additional information about a case assigned to the Criminal Investigation Section, 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 Criminal Investigation Section during regular business hours (Mon – Fri, 7 a.m. to 6 p.m.) your call will be directed to the appropriate detective or supervisor. If that person is not available, messages can be left on the detectives' voicemail for a return call when they are available. In emergencies or during situations that are in progress, please dial 9-1-1.
