How Warren County Processes Arrests
After someone gets arrested in Warren County, they are taken to the county jail in Warrenton for booking. The booking process generates the arrest record. Staff log the person's name, date of birth, physical description, charges, and arresting officer. Fingerprints and a photo are taken. Those fingerprints go to the state criminal history repository as required by Chapter 43.
The Warren County Prosecuting Attorney reviews the arrest and decides on charges. If formal charges are filed, the case enters the 12th Circuit Court. Bond is set based on the charges. The arrest record exists from the moment of booking whether charges are filed or not.
Warren County's proximity to the St. Louis metro area means its jail sometimes handles higher volumes than more rural counties of similar size. The booking and record-keeping process remains the same regardless of volume.
