The average case in St. Louis County is 2 1/2 days. If you are selected to serve, you will stay until that case is finished. If you are called to begin service on a Monday or Wednesday, and you are not selected by the end of the second day of service, you will be dismissed. If you are called to begin service on a Tuesday, you are usually required to serve 3 days. Occasionally, the jurors are dismissed after 1 day if the jury supervisor finds that all the courts have disposed of their cases and there will no longer be a need for any jurors. As you can see, it is hard to say exactly how many days will be required, but we ask that you plan on being present for at least 2 days.
