The Marshall County Inmate Population
Marshall County runs one detention facility. The Marshall County Jail at 520 Sixth Street in Lacon is the only confirmed lockup in the county, and the Sheriff's Department houses and maintains it. Jail officers stay on duty around the clock to book, process, and hold people who are arrested locally. Because the jail is small, the inmate population on any given day is small too, and it is made up of adults only. The county states that juveniles are not housed at the jail and must be taken to a juvenile detention facility instead.
The number of people in the Marshall County inmate population changes with the legal process, not with a fixed schedule. A new arrest adds someone to the jail. A bond ruling, a dismissal, a transfer, or a release takes someone out. When a person is convicted and sentenced to prison, custody shifts away from the county to the Illinois Department of Corrections (IDOC), so that individual leaves the county count and joins the state prison count. The official figures the public can verify come from the Marshall County Sheriff and from IDOC jail inspections, not from a live online dashboard.
The official county government page is a good first orientation point for the offices that touch the inmate population, from the sheriff to the courthouse. A look at the Marshall County government home page shows the courthouse and sheriff blocks that anchor every arrest, jail, and court question.

From that county hub, the sheriff page leads to jail capacity and visitation details, while the circuit clerk page leads to court records. Both matter, because a Marshall County inmate question almost always splits into a custody side and a court side.
Marshall County Inmate Population Statistics
The hard numbers for Marshall County come from two public sources: the Sheriff's Department page and the annual IDOC jail inspection reports. Those sources confirm a rated capacity of 16 beds and a physical plant of 8 double cells. They do not publish an average daily population, an annual booking total, or a demographic dashboard, so those figures are left out here rather than guessed at.
The table below gathers the sourced measures that public records actually support. Each row carries the office and year it came from, so a reader can check it.
| Measure | Figure | Source / Year |
|---|---|---|
| Rated bed capacity | 16 beds | Sheriff page; IDOC 2024 inspection |
| Male / female capacity | 12 male, 4 female | IDOC 2024 inspection |
| Cells | 8 double cells, 0 single | IDOC 2024 inspection |
| 2024 inspection-date count | 0 total | IDOC inspection, July 30, 2024 |
| County population baseline | about 14,000 | Illinois Sheriffs' Association profile |
These figures describe a tiny operation. A 16-bed jail with eight double cells is closer to a holding facility than a regional detention center, and that shapes how the public should search for someone held there.
Marshall County Inmate Population Trends
IDOC inspects the Marshall County Jail each year and records the population on the day of the visit. Those inspection-date counts are point-in-time snapshots, not yearly averages, so they cannot be read as a smooth trend line. They do show that the jail ran well below its 16-bed capacity on every inspection date reviewed, from 2020 through 2024.
The IDOC jail inspection archive holds the reports these counts come from. The IDOC county jail inspection reports index lists the annual files by year for facilities across the state.

Reading the snapshots in order shows how much a small jail can swing from one inspection to the next. The count moved from seven people in 2020 to zero on the 2024 inspection date.
| Year | Inspection-Date Count | Notes |
|---|---|---|
| 2024 | 0 | IDOC inspection July 30, 2024; capacity 16 |
| 2023 | 8 | 6 male, 2 female; capacity 16 |
| 2022 | 3 | 2 male, 1 female; capacity 16 |
| 2021 | 6 | 5 male, 1 female; capacity 16 |
| 2020 | 7 | 7 male, 0 female; capacity 16 |
Note: The yearly figures above are single-day inspection counts, so they show occupancy on one date and should not be read as an average daily population.
Who Makes Up the Marshall County Inmate Population
The makeup of the Marshall County inmate population is documented only in the parts that official sources actually report. The jail holds adults, both male and female. It does not hold juveniles, who must be moved to a juvenile detention facility. The 2023 IDOC inspection also states that the jail does not house detainees for other jurisdictions, which means the count is local people, not federal or out-of-county holds.
- Adults only - the jail has adult male and female capacity and no juvenile capacity.
- Sex breakdown by inspection - the 2023 count was 6 male and 2 female, while 2020 was 7 male and 0 female.
- Capacity split - the 2024 report lists 12 male beds and 4 female beds within the 16-bed total.
- No other-jurisdiction holds - the 2023 inspection says the facility does not house detainees for other agencies.
Race, ethnicity, charge level, and the split between pretrial and sentenced detainees are not published for Marshall County in the sources reviewed. Rather than invent those breakdowns, the safe statement is that public records give capacity and inspection-day counts, not a full demographic profile.
Marshall County Jail Capacity and Cell Layout
The Marshall County Jail was built in 1905, which makes it an unusually old small jail compared with modern regional centers. IDOC lists its capacity as 16 beds across 8 double cells, with no single cells and no detention rooms. The 2023 inspection adds the block layout: a Lower East, Lower West, Upper East, and Upper West block, each with two double-occupancy cells over two floors.
Capacity utilization on the inspection dates stayed below the rated limit every year reviewed. The point-in-time figures work out to 0 percent in 2024, 50 percent in 2023, about 19 percent in 2022, about 38 percent in 2021, and about 44 percent in 2020. No overcrowding order, consent decree, or capacity lawsuit was located in official sources, so the accurate picture is a small jail operating under its bed limit on the dates inspected.
Laws Governing the Marshall County Inmate Population
Several Illinois laws explain why jail population and booking information exists, who inspects the jail, and what the public can request. They are the reason an old county jail still files capacity and population figures every year, and the reason a resident can ask the sheriff for an arrest record. Each statute below is paired with a plain-English note.
Key Statutes:
Illinois FOIA, 5 ILCS 140 - makes records held by the sheriff and jail public, so booking and arrest information can be requested, subject to exemptions.
5 ILCS 140/2.15 - requires set arrest-report information to be furnished as soon as practical and within 72 hours of an arrest.
730 ILCS 5/3-15-2 - gives IDOC the authority to set minimum county jail standards and inspect the jail for compliance each year.
20 Ill. Admin. Code Part 701 - the County Jail Standards rules covering admission, records, classification, release, and population reporting.
Together these rules also require unusual-occurrence reporting and annual inspection. They do not, however, force a small county to publish a live online roster, which is why a Marshall County custody check leans on the phone and on records requests rather than a search box.
Marshall County and the Illinois Prison Population
Marshall County does not contain a state prison. No IDOC correctional center or work camp sits inside the county in the official IDOC facilities listing. That means the state share of the county inmate population is a transfer story, not a local facility story. When a Marshall County case ends in a felony prison sentence, the person leaves the county jail and enters IDOC custody somewhere else in Illinois.
For the public, the practical effect is that a sentenced person disappears from the local picture and reappears in the statewide Individual in Custody Search. The state system controls their current prison, custody identifier, and parole or release dates from that point on. The county jail may know that a transfer happened, but it is no longer the office that holds the record.
How to Search the Marshall County Inmate Population
Marshall County does not publish an official online jail roster, inmate search portal, or booking feed in the county sources reviewed. So a Marshall County inmate search is a decision tree, not a single web form. The fastest path depends on the custody stage of the person being sought, and the steps below run from a fresh local arrest outward to the state and federal systems.
Before starting, gather the person's full legal name, an age or date of birth, and the approximate arrest date and arresting agency. Common names are the main reason a search stalls, so a birth date matters more than it would at a large county.
- Decide the custody stage. A fresh local arrest points to the county jail; a prison sentence points to IDOC; a federal or immigration case points to BOP, the U.S. Marshals, or ICE.
- Call the Marshall County Sheriff and jail at 309-246-2115 for a same-day custody answer, since there is no roster to refresh.
- Search court records through the circuit clerk's Judici link once a case is filed, to see charges and court dates.
- File a written FOIA request with the sheriff for booking records, arrest reports, or a booking photo that is not given by phone.
- Check IDOC, the federal BOP, or ICE if the person has moved past the county jail or the jail cannot locate them.
Current Custody Lookup in Marshall County
Because the county does not run a public roster, a current-custody lookup uses people and paperwork rather than a search field. The jail is small and staffed at all hours, which makes the phone the most reliable real-time channel. The table below lists each access channel the research documents, what kind of request it is, and what it can do.
| Channel | Type | What It Does |
|---|---|---|
| Sheriff / jail phone (309-246-2115) | Verbal request | Best for same-day custody status; give name, age or date of birth, and arrest date. |
| In-person sheriff counter | Visit | 520 Sixth Street, Lacon, during office hours; bring ID and identifying details. |
| Written FOIA request | Records request | For booking records, arrest reports, and booking photos; direct in writing to the sheriff FOIA officer. |
| Court-record search (Judici) | Web search | Shows the filed case, charges, and hearings, not live jail custody. |
| IDOC, BOP, ICE locators | Web locators | For sentenced state, federal, and immigration custody after the county stage. |
| VINELink notifications | Web sign-up | Custody and case alerts where the agency reports data. |
Note: A booking may not be complete in the first hours after an arrest, so a same-day call to the jail can confirm whether someone is still in intake or already released.
Past and Released Inmate Records
Finding a person who is no longer in the Marshall County Jail follows a different path than a current-custody check. There is no public roster that keeps released names listed, so a past-custody question usually becomes a records request or a court-record search. A written FOIA request to the sheriff is the route for a historical booking record, an arrest report, or a release or transfer record.
If the arrest led to a filed case, the court docket is often the most durable public trail, since it survives long after the person leaves the jail. A docket can show the charges, the hearings, and the disposition even when the individual was released days earlier. For someone who was sentenced to prison, the record moves to the IDOC locator rather than any county archive.
What a Marshall County Inmate Record Shows
It helps to know what each booking field means even when it is not posted on a public profile. The jail keeps booking and personal records under Illinois jail standards, and a records request can ask for these fields by name. The table pairs each common field with what it would show and where the public route to it runs.
| Field | What It Shows |
|---|---|
| Booking Number | Internal intake identifier; not posted on a public county roster located in this review. |
| Booking Date | When intake happened; available in internal records, confirmed by phone or FOIA. |
| Charges | Early arrest charges; the court docket at Judici is the cleaner public route once a case is filed. |
| Bond / Pretrial Release | Set by the court under Illinois pretrial rules; the docket and court orders are the authoritative source. |
| Housing Unit | One of four two-cell blocks; not publicly posted. |
| Custody Status | In custody, released, or transferred; confirm by phone, VINELink, or the court docket. |
County Jail vs. State Prison: Where to Look
Readers mix up the county jail and the state prison system constantly, and in Marshall County the difference decides which tool to use. Pretrial detainees and short-term holds sit in the county jail, run by the sheriff. Sentenced felons move to IDOC, a separate system with its own locator. The comparison below keeps the two straight.
| County Jail | State Prison (DOC) | |
|---|---|---|
| Who Is Held | Pretrial plus short local holds | Sentenced felons |
| Run By | Marshall County Sheriff | Illinois Department of Corrections (IDOC) |
| Where to Look | Sheriff phone, in person, FOIA | IDOC Individual in Custody Search |
| How to Confirm | Call 309-246-2115; no public roster | Statewide online locator |
A useful glossary keeps the terms behind that table clear, since words like detainer and pretrial release shape who stays in custody and who does not.
- Pretrial release
- Release from custody before trial under court-set conditions; Illinois no longer uses cash bail for this.
- Detainer
- A hold or notice from another authority; the Marshall County Jail reported no other-jurisdiction holds in 2023.
- Remand
- A court order returning or keeping a person in custody.
- Classification
- The jail's decision about where and how to house a detainee.
- IDOC
- The Illinois Department of Corrections, the statewide prison system for sentenced felons.
- VINELink
- A public notification service for custody and case updates where agencies report data.
State and Federal Inmate Search
When the person has moved past the county jail, the search shifts to the statewide and federal locators. The IDOC Individual in Custody Search covers people sentenced to Illinois prison. The federal BOP inmate locator covers federal sentenced inmates from 1982 forward, and the ICE detainee locator covers adults in immigration custody.
The state locator is the one most Marshall County families will reach for, since a county felony case that ends in prison lands there. A quick look at the IDOC search page shows the statewide tool that replaces the county channels after sentencing.

For federal pretrial questions, the U.S. Marshals Service covers the Central District of Illinois, which includes Marshall County. Keep in mind that the 2023 jail inspection says the county jail does not house detainees for other jurisdictions, so a federal or immigration hold is searched in the federal systems rather than at the local jail.
Marshall County Detention Facilities
The county's detention map is short. One facility holds the local inmate population, and every other custody path leads to a system based outside the county. The list below names the local jail and what it holds.
- Marshall County Jail - the county's only jail, holding adult pretrial detainees and short local holds; no juveniles and no other-jurisdiction detainees.
Sentenced state prisoners are searched through IDOC, federal prisoners through the BOP, and immigration detainees through ICE, none of which operate a facility inside Marshall County.
Marshall County Inmate Population FAQ
How big is the Marshall County inmate population?
The Marshall County Jail has a rated capacity of 16 beds across 8 double cells. The actual count is usually well below that. IDOC inspection-date counts from 2020 through 2024 ranged from 7 down to 0, and the jail was under capacity on every inspection date reviewed. No average daily population is published, so the capacity and the inspection snapshots are the most reliable public figures.
How do I search the Marshall County inmate population?
There is no official online county roster. Start by calling the Marshall County Sheriff and jail at 309-246-2115 for a current custody answer. For charges and court dates, search the circuit clerk's Judici link after a case is filed. For booking records or a booking photo, file a written FOIA request with the sheriff. For sentenced or federal custody, use the IDOC, BOP, or ICE locators.
Is there a Marshall County jail roster online?
No official county roster, booking report, or mugshot gallery was located on the Marshall County sheriff or county pages. Search results that look like a Marshall County roster often belong to same-named counties in other states and should not be used. The reliable channels are the sheriff phone, the in-person counter, written FOIA requests, and the court-record search.
Where do sentenced inmates from Marshall County go?
When a county case ends in a prison sentence, custody moves from the county jail to the Illinois Department of Corrections. From that point the person is searched through the IDOC Individual in Custody Search, which holds their current prison, custody number, and release information. The county jail no longer keeps that record once the transfer happens.
Does the Marshall County Jail hold juveniles or federal detainees?
No. The county states that juveniles are not housed at the jail and must be transported to a juvenile detention facility. The 2023 IDOC inspection also says the facility does not house detainees for other jurisdictions, so federal and immigration detainees are searched through the federal BOP and ICE systems rather than the county jail.
How fast does a new booking show up?
No official source states a posting time, because there is no online roster to update. A person arrested within the last few hours may still be in intake. The practical answer is to call the jail directly, since there is no public refresh cycle to wait on and staff are on duty at all hours.
