| Field | Why it matters |
|---|---|
| Booking Number | Use this identifier for mail, deposits and jail-related transactions. |
| Arrest Date / Time | Helps establish when the current custody event began. |
| Arresting Agency | Shows which law-enforcement agency made the arrest. |
| Booked Date / Time | Shows when Riverside County completed the booking entry. |
| Case Number | Useful for matching the jail record with the court case. |
| Bail Amount | Shows the bail value currently displayed for the listed charge or case. |
| Current Facility | Confirms whether the person is currently listed at this jail. |
| Housing Unit | Important because Cois Byrd visitation schedules vary by assigned room/housing area. |
| Next Court Date | Shows the next displayed court event when one is available. |
| Court Name | Often identifies where the related criminal proceeding is scheduled. |
| Release Date | May show a release event, but the live custody status should still be confirmed if timing matters. |
Jail information can change as charges, bail, court orders or custody status are updated.
