Henry County Inmate Population and Inmate Search

The Henry County inmate population is the count of people held in the county jail in Cambridge and in the state prison that sits inside the county. Most are local. Some are held for outside agencies. This is the hub for the Henry County inmate population in Illinois, both the numbers behind it and the day-to-day question of how to find a single person. You can use it to understand who is counted, how the population has shifted, and how to run a Henry County inmate search when a name is all you have. Pre-trial detainees, sentenced prisoners, and federal holds each live in a different records system, and knowing which one applies saves time.

The Henry County Inmate Population

Two facilities hold the Henry County inmate population. The first is the Henry County Jail, run by the Henry County Sheriff's Office at 311 West Center Street in Cambridge. It holds criminal suspects, people convicted of Henry County crimes who draw jail sentences, and detainees housed for outside agencies. The county Corrections Division also confirms that the jail keeps U.S. Marshals Service detainees, a detail the 2024 state inspection repeats. The second facility is the Kewanee Life Skills Re-Entry Center, an Illinois Department of Corrections prison for sentenced adult men. It is not a county jail and should never be searched as one.

The day-to-day size of that population rises and falls with arrests, release decisions, and transfers. A new arrest adds a person to the jail count. A judge's release order or a transfer to state prison subtracts one. Because Illinois ended cash bail in 2023, pre-trial release now turns on court findings rather than a posted dollar amount, which shapes how long many people stay in the jail. The numbers below come from official Illinois Department of Corrections jail inspections, the only public, dated counts located for the Henry County jail.


Henry County Inmate Population Statistics

The headline figures for the Henry County inmate population come from the state's most recent jail inspection, dated September 25, 2024. The jail carries a rated capacity of 132 beds, split into 116 male and 16 female beds, with no juvenile beds. On the inspection date it held 66 people, which is exactly half of the rated capacity. The county runs two detention facilities in all. Figures with no published source, such as annual bookings or a year-round average daily population, are left out rather than guessed.

The Henry County Corrections page is the official starting point for jail contact details and a plain statement of what the jail does. It sets the scene for every number on this page.

The official Henry County Corrections Division page lays out the jail's address, phone line, and custody role.

That page is where the county describes the jail as the secure home for suspects and sentenced county inmates, which frames the population counts that the state inspection later measures.

Who Makes Up the Henry County Inmate Population

Official sources break the jail population down by sex and by juvenile status, but not much further. On the 2024 inspection date the jail held 56 men and 10 women, or about 85 percent male. No juveniles were held, and the jail carries no juvenile beds. The county has not published a pre-trial versus sentenced split, a race or age breakdown, or an average length of stay, so those are noted here as gaps rather than filled with estimates.

  • Sex - 56 male and 10 female on the September 25, 2024 inspection date.
  • Adult vs. juvenile - all adult; juvenile capacity and count were both zero.
  • Held for other agencies - the jail houses U.S. Marshals Service detainees alongside local inmates.
  • Pre-trial vs. sentenced - not published in the official sources located for Henry County.

The county's Corrections page adds that housing inmates for outside agencies has become a real source of revenue for Henry County, which helps explain why the population is not only local arrests.


Henry County Jail Capacity and Overcrowding

Overcrowding is not the story here. With 132 rated beds and 66 people on the 2024 inspection date, the jail sat at half of capacity. The female side ran near 63 percent of its 16 beds, while the male side held about 48 percent of its 116. The 2024 inspection did flag one compliance issue: documentation of the required 30-minute observation checks appeared complete only about 91 percent of the time, and the state directed the jail to add staff or other measures to bring supervision fully into line. The same report listed real improvements, including a new iris scanner, an updated commissary, reopened outdoor recreation, and new locks and handles.


Laws Governing the Henry County Inmate Population

Several Illinois laws set how jail data is collected, reported, and released. The state's jail-standards authority lets the Illinois Department of Corrections write minimum rules for county jails and inspect them, which is why a public Henry County inspection exists at all. County jail standards require around-the-clock supervision, monthly population reports, and head counts. The Freedom of Information Act makes most jail records presumptively open while still allowing safety and privacy exemptions, and a separate law requires reporting whenever a person dies in custody.

Key Statutes:

730 ILCS 5/3-15-2 - lets IDOC set minimum jail standards, inspect county jails, and seek court enforcement for ongoing noncompliance.

20 Ill. Adm. Code Part 701 - county jail standards covering 24-hour supervision, monthly population reporting, and physical head counts.

5 ILCS 140 (Illinois FOIA) - makes public-body records presumptively open, with the body carrying the burden to justify any exemption.

730 ILCS 210/3-5 - requires law-enforcement and correctional bodies to report deaths of people held in custody.


Henry County and the State Prison Population

Once a person is sentenced to state prison, they leave the county-jail count and join the Illinois Department of Corrections population. Henry County has one IDOC facility inside its borders, the Kewanee Life Skills Re-Entry Center, which opened in 2017 for sentenced adult men preparing to return to the community. The center is rated for 682 and held 192 people as of June 30, 2024. A person can vanish from the local jail path after a transfer to state custody, which is normal; from that point the Illinois Department of Corrections inmate search is the right tool, not the county jail.



Current Inmate Lookup in Henry County

For someone booked into the Henry County Jail right now, the live channels are the jail information line at 309-937-3940 and Illinois VINE for status notifications. VINE interfaces with county jail booking systems, the state corrections department, and circuit court clerks, and it lets you register for custody and court alerts by phone, text, email, or app. It is a notification service rather than a guaranteed full roster, so what it shows depends on the agency feed behind it. When a person has been sentenced and moved to state prison, the IDOC search below takes over. Its fields are simple.

Past and Released Inmate Records

Finding someone no longer in custody takes a different route. Because no public jail roster was located, there is no archive of dropped-off bookings to scroll. For a past Henry County booking, the sheriff's Records unit at 309-937-3616 archives reports generated by office personnel and enters them into an internal database, and a Freedom of Information Act request to the sheriff covers booking records and incident reports that are not handed out by phone. For a person sentenced and released long ago, the state corrections department keeps the locator focused on people currently incarcerated or on parole; completed sentences generally do not display and must be requested through an archived records search.


What a Henry County Inmate Record Shows

Because the county does not publish an online inmate profile, the fields below describe what is confirmed through official non-roster sources rather than what a public web profile would display. The jail itself will not discuss housing, medical, commissary, or disciplinary details with friends and family. Charges, bond, and court dates are best confirmed through the court case rather than the jail.

FieldWhat It Shows
FacilityHenry County Jail, 311 West Center Street, Cambridge, per the county and the state inspection.
Custody typePre-trial suspects, sentenced county inmates, and outside-agency or U.S. Marshals detainees.

County Jail vs. State Prison: Where to Look

Readers mix up the two systems constantly, and the mix-up wastes hours. Pre-trial detainees and people serving short county sentences sit in the Henry County Jail, run by the sheriff. Sentenced felons move to an Illinois Department of Corrections prison, a separate system with its own locator. The county jail covers the front end of a case, while the state locator covers people after a prison sentence. Use the table to match the person to the right search.

Henry County Detention Facilities

Two facilities hold part of the Henry County inmate population, and they serve very different readers. One is a local jail for arrests and short sentences. The other is a state reentry prison for sentenced men. Send a family member of a sentenced prisoner to the wrong one and the search fails before it starts.

  • Henry County Jail - the sheriff's county jail in Cambridge holding pre-trial detainees, short county sentences, and U.S. Marshals detainees.
  • Kewanee Life Skills Re-Entry Center - an Illinois Department of Corrections prison for sentenced adult men in a reentry program, not a booking jail.

Booking photos for current inmates are covered on the Henry County jail mugshots page, while the roster how-to lives on the jail inmate records page.


Henry County Inmate Population FAQ

How big is the Henry County inmate population?

On the most recent state jail inspection, dated September 25, 2024, the Henry County Jail held 66 people against a rated capacity of 132 beds. That is half of capacity. The number is a single-day snapshot from the inspection, not a year-round average. Earlier inspections counted 90 in 2022 and 86 in 2023, so the short trend points down.

How do I search the Henry County inmate population?

No official public online jail roster was located. To check a current inmate, call the jail information line at 309-937-3940. For a court case, search the Circuit Clerk's Judici link by name. For a sentenced state prisoner, use the Illinois Department of Corrections locator. For federal or immigration custody, use the BOP or ICE locators instead.

Can I look up a released or past inmate?

There is no public archive of past bookings on the county site. For an older Henry County booking, contact the sheriff's Records unit at 309-937-3616 or file a Freedom of Information Act request with the sheriff. For a released state prisoner, the IDOC locator shows current inmates and parolees, and completed sentences require an archived records request.

Is the Kewanee center part of the county jail?

No. The Kewanee Life Skills Re-Entry Center is an Illinois Department of Corrections prison for sentenced adult men, not a county jail. People held there are searched through the state locator, never the county jail line. A newly arrested person would be at the Henry County Jail instead.

Directions to the Henry County Jail

The Henry County Jail sits at 311 West Center Street in Cambridge, the county seat, on the same courthouse block as the Circuit Clerk and the State's Attorney. The courthouse and clerk addresses sit next door at 307 West Center Street, so jail, court, and clerk business clusters in one downtown area rather than across separate campuses. Cambridge is in northwestern Illinois, near Interstate 80 and Interstate 74, with the Quad Cities International Airport roughly ten minutes from the county area. The official jail page does not publish turn-by-turn driving directions, so confirm your final route in a maps app before leaving.
