Jail Roster Search Through IDOC
The Illinois Department of Corrections runs a statewide inmate search tool. It covers people who serve state felony sentences in Illinois prisons.

You can use the IDOC offender search portal to look up anyone in state custody. Search by name or IDOC number. Results show the person's full name, date of birth, current facility, admission date, and projected discharge date. The tool also lists race, sex, height, weight, and other physical details. For people who were arrested in Rock Island County and later sentenced to state prison, this is where you will find them. The county jail roster only holds those still at the local level in Rock Island County.
The IDOC search portal below shows the state-level tool used across all of Illinois, including for inmates who were originally booked in Rock Island County.
IDOC also keeps a wanted fugitives list with photos and last known addresses.

How Rock Island County Jail Works
The jail in Rock Island County holds three main groups. First, people who have been arrested and are waiting for bond or trial. Second, those who have been sentenced to serve county time for misdemeanors or short felony terms. Third, people held for other agencies like the U.S. Marshals or immigration authorities.
After an arrest in Rock Island County, the person goes through booking at the jail. This creates the jail roster entry. Booking includes taking photos, fingerprints, and personal details. Charges are listed and a bond amount may be set by the court. The person stays on the Rock Island County jail roster until they post bond, get released, or get transferred somewhere else. Under 730 ILCS 5, the Unified Code of Corrections governs how inmate records are maintained at both the state and county level in Illinois. The Rock Island County jail follows these same rules for record keeping.
