How Are Inmate Records in Illinois Created and Stored?

Illinois inmate records are first created when someone is arrested and held in custody. The initial paperwork, called a RAP sheet, contains the person's name, address, physical description, and information about the crime they committed. After that, whenever the person is moved to another facility, has a hearing or trial, it is noted in the file. The Illinois Department of Corrections is the government agency that collects, manages, and stores all inmate records in a centralized database. This repository is helpful so that anyone can find an Illinois prison inmate quickly and easily.

How to Find if Someone is in Jail or Prison in Illinois?

The Department of Corrections has a handy Illinois inmate locator feature on their website, and they allow any non-law enforcement individuals to perform an Illinois inmate search online to find someone locked up in prison. When searching, it's helpful to know the offender's IDOC (inmate ID), but if not, searchers can use the person's last name or birthdate instead. The results show a relatively simple list with only the IDOC number, birthdate, and name. By clicking to highlight an entry and hitting the "Query a Highlighted Inmate" button, the visitor can see additional details. When performing an official Illinois inmate search, always contact the state DOC to find an inmate. Infotracer’s search tool provides a good alternative for finding inmate records for private searches.

How to Search for Federal Prison Inmates

When conducting an Illinois inmate search for someone in federal prison, the process will be different than for someone in state prison. All federal prisons are under the jurisdiction and management of the Federal Bureau of Prisons (FOB). Therefore, anyone wanting to look up a federal Illinois inmate must contact the FOB directly, call the facility where they are being held or use the offender search feature on the FOB website.

Illinois County Jails

Illinois has 102 counties throughout the state. Each county has a local Sheriff's Office, and they operate and maintain their own county jail. Inmates held in the county jail are those who were just arrested and are awaiting either a hearing or trial or those who were sentenced and are waiting to be moved or will serve their entire short sentence in county jail. Each county Sheriff's Office has jurisdiction and control over the county jails.

How to Perform an Illinois Jail Inmate Search

Since the local Sheriff's Office manages each county jail, the inmate data is not integrated with the Illinois Department of Corrections. Therefore, when someone wants to locate an inmate in an Illinois jail, they must contact the Sheriff's Office directly. Many of the county Sheriff's Offices have websites with an inmate locator feature on them. If they do not, visitors can call to find out if someone is being held there.

Illinois Juvenile Detention Centers

Illinois also keeps five juvenile detention centers active to help and house youth offenders younger than 18 years old. All five are operated and supervised by the Illinois Department of Juvenile Justice (IDJJ). The Illinois detention centers are:

  • IYC Chicago
  • IYC Harrisburg
  • IYC Pere Marquette
  • IYC St. Charles
  • IYC Warrenville

 

Illinois also has some county juvenile detention centers, but they fall outside of the responsibility of the IDJJ.

How to Search for Juvenile Detention Center Inmates

Juvenile criminal records are typically sealed until a person is 18 years old, and then they are often expunged. Generally, only family, friends, and trusted agents are able to get information about someone incarcerated in an Illinois juvenile detention center. However, interested parties can contact the Illinois Department of Juvenile Justice (IDJJ) or the juvenile detention center directly to find out how to visit, how to send gifts or mail, or get more information.

Illinois Transitional Facilities

The state of Illinois is committed to reducing recidivism through its transitional center program. Once an inmate nears their release date, they are moved to a low-security facility to transition back into life by getting a job, secure housing, and other "normal" life activities. The four transitional centers in Illinois are:

  • Crossroads Adult Transition Center.
  • Fox Valley Adult Transition Center.
  • North Lawndale Adult Transition Center.
  • Peoria Adult Transition Center.

Each center holds fewer than 500 inmates.

How to Search for an Inmate in an Illinois Transitional Center

All the facilities in the Illinois prison system fall under the same umbrella of the Department of Corrections. Therefore, all inmates are in the same centralized database. The process for finding an Illinois inmate is identical to finding a state prison inmate. Follow the steps below:

  1. Visit theIllinois Department of Corrections website.
  2. On the main menu, choose "Offender Search" and then "Inmate Search."
  3. Choose your method of searching; your choices are Last Name, Birthdate, and IDOC Number.

  5. Hit the Find button.

  7. Review the details of that inmate.

Why are People Incarcerated in Illinois?

More than 76,000 prisoners are incarcerated in Illinois. Although this figure stands out internationally, it pales in comparison with the national average in the U.S. Most of the inmates are in state prison or local jail because of murder, rape, and drug charges. By far, those are the most common reasons for imprisonment in Illinois. Assault and battery is another top reason that people are incarcerated in Illinois.

Illinois’s Incarceration Rate and Statistics

Illinois’s incarceration rate for year-end 2016 under state prison or local jail jurisdiction per 100,000 population was 341, which is lower than an average incarceration rate by 24%. The number of Illinois prisoners at the year-end of 2016 was 43,657, from which 6% were female prisoners, whereas the number of male prisoners was 41,044 in 2016.

Where Do Illinois Inmates Go When They are Released?

Many Illinois inmates will return home to family and friends after being released from prison. However, for some that qualify, Illinois has a program where they are moved to a transitional center which works much like a halfway-house. Inmates are supervised and stay in a low-security facility where they are assisted in getting jobs, securing housing, and getting reacquainted with family so that their re-entry back into society will be successful.

How Does Parole Work in Illinois?

Parole is when an inmate is released early from prison but must follow strict guidelines, or they will lose this privilege and go back to prison. Part of this supervisory program includes the inmate checking in with a parole officer regularly. Illinois makes this easy with their seven Day Reporting Centers that are open 365 days per year. Only inmates who behave well and are committed to rehabilitation get offered parole in Illinois.

How Does Someone Get Probation in Illinois?

During the sentencing phase of a trial in Illinois, the judge has the option of ordering probation instead of jail or prison. This is usually only offered to first-time or low-risk offenders. The probation program comes with strict rules, including checking in with a probation officer and other court-ordered stipulations. If an offender violates even one of the rules, their probation will be revoked, and they will immediately go to prison.
