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 last quarter. We saw a 15.8% decrease in crime in the 4th quarter of 2014 compared to the 3rd quarter of 2014. 


I would also like to acknowledge the residents and business owners in the Affton Southwest Precinct for their continued support of the Police Department during this challenging time. The outpouring of support and well wishes reinforces why we chose this profession. This support from the community is instrumental in helping the officers to strive to maintain the highest level of professionalism and commitment that the citizens and businesses of the precinct deserve. 

Even though the Holiday Season has come to an end we want to still remind residents to secure their vehicles and belongings. Our largest number of larcenies in the precinct comes from unsecured vehicles with valuable items in plain view. One of our main goals is to try and inform/remind residents not to leave anything of value in their vehicles and lock your doors. Many thieves see the valuables inside the car and will then try the door handles to see if they are unlocked. If they can't see anything of value and the vehicle is locked chances are they will move on without disturbing your vehicle. If you see any suspicious activity in your neighborhood or anywhere in the precinct please call 911 to report it. 

I, along with all the men and women of the Affton Southwest Precinct, want to wish everyone a happy and safe 2015!

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.
