The Professional Standards Division offices are open for complaints during normal business hours 8:00 a.m. to 5:00 p.m., Monday through Friday. A complaint may also be called in by telephone or by going to any of the nine troop headquarters located around the state. You can reach the Professional Standards Division by calling telephone number (573) 751-8801 or the General Headquarters switchboard at (573) 751-3313. Complaints may also be mailed to the Professional Standards Division at: 1510 East Elm Street, Jefferson City, MO 65102-0568. Letters of complaint should contain your name, address, and telephone number along with the involved employee’s name and/or badge number (if known), and the date of the incident.

When a citizen lodges a complaint against a Patrol employee the complaint is forwarded to the Professional Standards Division even if it is lodged at a troop headquarters. Once the complaint is received in the Professional Standards Division an investigator assesses the complaint. After this review, the complaint is assigned for investigation. An investigator will contact you in order to obtain any additional information that is needed.
