Tough, No Nonsense Agency

The St. Charles County Prosecuting Attorney's Office has a rich tradition of excellence as a tough, no nonsense law enforcement agency that pursues community safety and justice with professionalism, integrity and fairness. Today, your Prosecuting Attorney's Office remains deeply committed to these values even as we face extraordinary challenges and new crimes that were never imagined a half century ago.

Thankfully, our community is one of the safest in the nation and boasts several cities that regularly rank among most desirable places to live in the United States. Yet we are not untouched by crime. Each year my office works with several hundred crime victims who are seeking help and justice for a wide variety of offenses.

Our prosecutors file thousands of criminal cases annually in a persistent battle against illicit drugs, child abuse, domestic violence, theft and many other threats to the well-being of our communities. We also confront dramatic changes in science and technology that affect both the nature of crime and our approach to solving and prosecuting cases.


While we celebrate the dedication and commitment of the members of this office, we also gratefully acknowledge the outstanding work of local law enforcement, the financial stewardship of the St. Charles County Council, and, above all, the longstanding support of the community we serve.

Please know that as your Prosecuting Attorney, I will continue to do my very best to keep our community safe, our justice system fair, and to pursue that is true and just every case, every day.

Very truly yours,

Tim Lohmar
Prosecuting Attorney
