Find Cass Jail Booking Records Online
A booking record is created each time someone is processed into the Cass County Jail. During booking, jail staff record key details about the arrest and the individual being held. A typical booking record includes:
- Booking number
- Date and time of booking
- Charges at the time of intake
- Arresting agency (e.g., Cass County Sheriff's Office, local police department, Missouri State Highway Patrol)
- Personal identifiers such as name and date of birth
The most straightforward way to view current booking records is through the online inmate roster. This list reflects individuals currently in custody and includes the information generated at booking.
If you need booking records for someone who has already been released, those records may not appear on the live roster. In that case, contact the Cass County Sheriff's Office at (816) 380-5200 to ask about a records request. For individuals who were transferred to state custody, the Missouri Department of Corrections Offender Search may have additional information. Arrest records from state troopers can also be looked up through the Missouri State Highway Patrol arrest reports page.
Search the Cass Jail Roster by Last Name or Booking Number
The Cass County Sheriff's online roster supports two practical approaches to finding an inmate:
By Last Name
- Use your browser's find function (Ctrl+F or Cmd+F) on the inmate roster page and type the person's last name.
- If you're unsure of the exact spelling, try a partial name — entering the first several letters can help narrow results.
- Adding a first name can help if the last name is common.
By Booking Number
- If you already have a booking number, use the browser find function to search for it directly on the roster page.
- Booking numbers are unique identifiers, so this method returns an exact match when the person is still in custody.
If Your Search Returns No Results
- Double-check the spelling of the name.
- The individual may have been released, transferred, or booked under a different name (legal name vs. alias).
- Call the jail at (816) 380-5200 to verify whether the person was recently released or is held at another facility.
- If the person may be in state prison rather than county jail, try the MODOC Offender Search.
Jail Roster Updates and Search Limitations in Cass
The Cass County Sheriff's Office updates its online inmate roster on a regular basis, but there can be a delay between when someone is booked and when their name appears on the website. Processing, data entry, and system synchronization all take time — especially during overnight hours or weekends when staffing levels may differ.
Key Limitations to Keep in Mind
- Booking-to-posting delay: A newly arrested person may not show up on the roster for several hours after intake.
- Releases: Once an inmate is released — whether on bond, by court order, or after serving a sentence — their record is typically removed from the roster. The online list reflects current custody only.
- Not an archive: The roster is not a historical database of all past bookings. If you need records for someone who is no longer in custody, you will need to contact the Sheriff's Office directly.
- Data accuracy: The roster is labeled as informational only. Charges listed may be preliminary and can change as a case moves through the Missouri court system.
- Transfers: Inmates transferred to state facilities or other jurisdictions will no longer appear on the Cass County roster.
For the most current and reliable custody status, call the Cass County Jail at (816) 380-5200.
