Jefferson County's jail handles a significant number of bookings each year. The county sits in the St. Louis metro area and has a suburban and rural mix.

Jefferson County Arrest Records and the Sunshine Law
Missouri's Sunshine Law in Chapter 610 RSMo governs all Jefferson County arrest records. The 30-day open period applies to every law enforcement agency in the county. During that window, records must be provided on request. No reason is needed. Copy fees can be charged but must be reasonable and based on actual costs.
After 30 days, the arrest record closes if charges were not filed. If the Jefferson County Prosecuting Attorney charged the person, court records remain open on Case.net. This two-tier system means the arrest report may become inaccessible while the court case file stays public. For most practical purposes, the court record contains the key information people want: what someone was charged with, what happened in court, and how the case ended.
Juvenile records are sealed in Jefferson County. Expunged records are removed from databases. If a Jefferson County agency improperly denies your request, the attorney general's office investigates Sunshine Law complaints.
