Captain's Message

photo of Captain DierkesGreetings,


 I would like to thank the residents and business owners of the Affton Southwest Precinct for their diligence in helping keep our community a safe and enjoyable place to live and work.  Thanks to the cooperative effort between all of you and the St. Louis County Police Department we have seen an overall decrease in our crime rates here in Affton over the busy summer months.


The mission of the St. Louis County Police Department is to work cooperatively with the citizens we serve, and within the framework of the Constitution to enforce the laws, preserve the peace, reduce fear and provide a safe environment in our neighborhoods.  To accomplish our mission we must build a strong partnership between the police department and the citizens of this community.  In my mind, one of the most effective ways to create this partnership is through programs such as the Citizens Police Academy.


The Affton Southwest and South County Precincts will be hosting a Citizens Police Academy starting on Wednesday, September 3rd, 2014.  The academy will be held every Wednesday evening from 6:30-8:30 p.m. at the Green Park City Hall, 11100 Mueller Rd., suite 5.  If you are interested in participating in this program please contact your local Precinct for an application prior to attending. This academy is open to all residents and is free of charge.  This is an excellent opportunity to learn about the inner workings of some of the specialized units we have available in the St. Louis County Police Department.  I invite you all to attend this worthwhile program.


Affton Southwest Precinct Goals

  • Provide the public with reasonable and efficient access to public services.
  • Be responsive to calls and identified needs for police services within the precinct 24 hours a day.
  • Allocate personnel to obtain maximum utilization of its human resources to meet identified needs.
  • Provide staff services for the traditional line functions of the police.
  • Maintain a proactive approach toward crime and disorder.
  • Identify criminal activity and act to resolve it.
  • Maintain activities to facilitate the orderly flow of people and vehicles within the community.
  • Maintain positive interaction with the public and a high degree of visibility within the community.

Report Crime ... Make the Call

If you see a crime in progress or another emergency situation that requires an immediate police response, call 911. Provide the call-taker with a good description of the incident, the offender, and the exact location.

For non-emergencies, however, do not call 911. Non-emergency calls to 911 can slow the response time to true emergencies. The number to call for non-emergencies is (314) 889-2341.
