Understanding Johnson County Jail’s Online Roster: What Each Column Means

If someone you know is at the Johnson County Jail, the online roster can help you confirm you're looking at the right person and make sense of their current status. This guide walks through what each roster column means, what you'll typically see on a detail page (charges, bond, and detainers), and what to do if something looks outdated or confusing.

Each row on the Johnson County online jail roster is organized into the same columns: Date Booked, Name, Age, Date Released, Housing, and Facility Details. Date Booked shows when the person was processed into the jail. Name and Age help you identify the right person. Date Released gets filled in once a release date is on record. Housing tells you where the person is being held, and Facility Details shows which facility listing is tied to their roster entry.

• ✓ Check Date Booked to see when the person was booked into the jail
• ✓ Use Name and Age together to help confirm you have the right person
• ✓ Look at Date Released for a listed release date when it appears
• ✓ Read Housing to see the roster’s housing location label for that person
• ✓ Use Facility Details for the roster’s facility information tied to that entry

Click into an individual's detail page and you'll see a charge list with the offense name and a statute citation. For example, one roster detail page shows "OWI 3RD OFFENSE" with the citation "321J.2(2c)." On that same charge line, bond information appears too: in this case, a cash bond for $35,000.00 with a status of PENDING.

Charges can also appear with their own separate bond lines. One detail page lists "Intimidation with a Dangerous Weapon" with the citation "708.6(2)," showing a cash bond of $20,000.00 and a PENDING status. When scanning multiple charges, start with the charge name and citation, then match each to its bond type, bond amount, and status on the same line.

Some detail pages include a detainer section. A detainer is a hold placed by another agency, and it can prevent someone from being released even if their bond situation changes. For example, one Johnson County roster detail page lists ICE as the detainer agency, with the status shown as "Not Released."

More than one detainer can appear on the same page, and each may have a different status. One detail page shows a Johnson County detainer with "Detainer Released: Yes," while a separate GPS detainer on the same page is listed as "Not Released." If you see multiple detainer entries, read each line individually. Don't assume they all share the same status.

Johnson County Jail has a capacity of 92 inmates. With a limited number of beds, housing assignments can shift, and space constraints may affect where someone is held at any given time.

All arrests made in Johnson County are brought to the Johnson County Jail, including those made by other agencies in the county. That steady flow through intake is one reason the roster changes quickly, and why housing and placement can shift as the jail manages its population.
