The Marshall County Inmate Population
The official local custody map is narrow. Marshall County Jail is the only detention facility found in local official sources, and it is run by the Marshall County Sheriff's Office. The jail holds adults booked by the sheriff, Marshalltown Police, courts, warrants, state or federal agencies, and other held-for agencies when the person is physically housed in the county jail. Iowa Code Chapter 356 is the key jail statute because it places charge and custody of county jail prisoners with the sheriff until they are discharged by law.
The Marshall County inmate population should not be read as one single database. A person may start in the sheriff's roster, appear later in Iowa Courts Online after charges are filed, and move to Iowa Offender Search after a state sentence. Federal pretrial custody, sentenced federal prison, and immigration custody have separate lookup paths. The local roster can still show Federal or ICE/Immigration held-for-agency values when the person is housed in Marshall County Jail, but a transfer may move the public trail away from the county system.
Marshall County Inmate Population Statistics
The strongest current local number in the research is the rated jail capacity. The Marshall County Sheriff's Office jail page describes the facility as a direct-supervision jail with 182 beds. The same page states that the jail opened in July 2000 at the former Marshall County Care Facility site. A live roster exists, but the research did not capture a reliable published average daily population, annual booking count, or demographic report from an official static county source.
| Measure | Figure | Source / Year |
|---|---|---|
| Marshall County Jail capacity | 182 beds | Sheriff jail page, inspected June 2026 |
| Jail opening | July 2000 | Sheriff jail page |
| Facility design | Direct supervision | Sheriff jail page |
| Current ADP | Not published in official local static sources | Research gap |
| Historical ICE bed capacity | 60 ICE beds within 182 total beds | ICE ODO inspection, 2015 |
Marshall County Inmate Population Trends
Marshall County has a live jail roster, not a public population dashboard. That matters because a roster can answer who is in custody today, while an average daily population report would show long-term use of jail beds. The research found statewide context from Vera and Prison Policy Initiative, but no official county trend table for bookings, length of stay, or pretrial share. Those statewide sources are useful context, not a substitute for a Marshall County figure.
| Year | Population marker | What it means |
|---|---|---|
| 2000 | 182-bed jail opened | Facility capacity marker, not an ADP count |
| 2015 | 182 total beds and 60 historical ICE beds | Federal inspection context, not proof of a current contract |
| 2026 | Live Zuercher roster exists | Current custody can be searched, but no official ADP was posted |
The safest reading is conservative: use the 182-bed figure as the official local capacity and use the roster only as a current-custody search. If a published population count is needed for legal, media, or policy work, ask the sheriff's office for the date-specific count or a public-record copy rather than estimating from older reports.
Who Makes Up Marshall County Inmates
The public roster has individual fields that can describe a person in custody, but the research did not find an official aggregate demographic dashboard for Marshall County Jail. The roster configuration includes race, sex, age format, arrest date, held-for agency, in-custody status, release-date fields, and cell-block values. Those fields help a user search and read an inmate entry. They do not prove the makeup of the whole jail population unless the county publishes totals or a date-specific roster count is captured and described that way.
- Held-for agency
- The agency connected to the custody hold, such as Marshall County, DOC, Federal, or ICE/Immigration.
- Cell block
- A housing or classification label. Marshall County values include Booking, Female General, Male General, Special Status, Trustee Dorm, and others.
- Pretrial detainee
- A person held before final case disposition, often because of bond, warrant, court order, or another hold.
- Sentenced state prisoner
- A person moved into Iowa DOC custody after a state prison sentence, searched through Iowa Offender Search.
Marshall County Jail Capacity
The Marshall County Jail capacity number is clear, but the current overcrowding picture is not published in the static official materials captured for this build. The sheriff's page identifies a modern direct-supervision design with 182 beds. Research did not locate an official current overcrowding dashboard, consent decree, construction plan, or recent death-in-custody report for the jail. The PREA page, however, does publish recent annual summaries and audit material for jail conditions and reporting.
Because no local ADP was located, the capacity section should be read as a facility fact rather than a claim about crowding. A live roster count can change by booking, release, bond, court transfer, or transport to another agency. For a formal count on a given date, the sheriff's records route is the more precise channel.
Marshall County Inmate Population Law
Iowa law gives the public broad access to records, while also protecting investigative, juvenile, privacy, and safety-sensitive material. Jail roster facts such as current and prior arrest data are different from a full investigative file. A booking record may be public in part, while witness statements, evidence, juvenile data, and some law-enforcement intelligence may be withheld or redacted.
Key Iowa sources:
Iowa Code Chapter 22 governs public records and the right to examine records unless an exception applies.
Iowa Code 22.7 lists confidential-record exceptions, including limits that often matter for law-enforcement files.
Iowa Code Chapter 356 covers county jails and the sheriff's custody of prisoners.
Iowa Code Chapter 804 covers arrest and disposition of prisoners, including initial court appearance rules.
Marshall County and State Prison
After a state prison sentence, the lookup path changes from Marshall County Jail to the Iowa Offender Search. The DOC search is a statewide system for prison and community-corrections records. It is not the county roster and does not serve the same population. DOC material says offender data is public information under Iowa Code 904.601(1), updates weekly, and may change quickly.
No Iowa DOC prison was found inside Marshall County. The DOC location list still matters because people convicted in Marshall County can be assigned to state institutions elsewhere or to Second Judicial District supervision. The county jail roster is the first place to check for a recent booking, but Iowa Offender Search is the better path after sentencing and transfer.
Search Marshall County Inmates
The primary online lookup channel is the Marshall County Zuercher inmate list. It is linked from the sheriff's website and is configured for public jail roster searches. The roster is strongest for current and very recent county jail custody. It is weaker for complete case history, old booking records, court filings, or records after a transfer.
- Open the Marshall County inmate list and start with a name search.
- Use race, sex, arrest date, held-for agency, or in-custody fields only when a broad name search returns too many results.
- Read the public columns for mugshot, name, race, sex, arrest date, age, and held-for agency.
- Check hold reasons for warrants, charges, bond text, or agency holds when visible.
- If no county result appears, check Iowa Courts Online, Iowa Offender Search, BOP, ICE, or call the jail.
Marshall County Roster Fields
The Zuercher portal exposes a specific search setup. The name field is optional in the configuration, race and sex are dropdowns, and the in-custody date is limited to a recent window. The public roster does not require a login. It also does not show juveniles in the same way as adult records, because the public configuration has juvenile display turned off for normal adult roster use.
| Field | Type | Required | Notes |
|---|---|---|---|
| Name | Text | Optional | Search by inmate name; exact wildcard rules were not posted. |
| Race | Dropdown | Optional | Includes White, Black or African American, Asian, American Indian or Alaska Native, Native Hawaiian or Other Pacific Islander, and Unknown. |
| Sex | Dropdown | Optional | Female, Male, or Unknown. |
| Cell Block | Dropdown | Optional | Includes Booking, Female General, Male General, Trustee Dorm, Special Status, Out of County, and other jail categories. |
| Arrest Date | Date picker | Optional | Controlled by the portal date picker. |
| Held For Agency | Dropdown | Optional | Includes local, DOC, Federal, ICE/Immigration, and many other agency values. |
| In Custody | Date/status | Optional | Default behavior uses the current date with a seven-day limit in configuration. |
The official county directory screenshot captured in the image set shows the sheriff divisions, address, phone numbers, hours, and links from the county source. The county sheriff directory is the source page for that contact context.
Past Marshall County Inmate Records
A released person may disappear from the roster when the live custody record no longer fits the portal's filters. The research did not find a separate official archive, daily booking report, or recent-bookings gallery. For older sheriff records, the records route is by mail: send the request, a self-addressed stamped envelope, and the posted report-copy fee to Marshall County Sheriff's Office, ATTN: Records, 2369 Jessup Avenue, Marshalltown, IA 50158.
Court records after an arrest are searched through Iowa Courts Online and the Marshall County Clerk of Court. That system is the better source for case numbers, charging documents, hearings, dispositions, and court debt. Jail custody and court filing are linked in time, but they are not the same record.
Marshall County Inmate Record Fields
A typical public row can answer basic custody questions. It may show a mugshot, the person's name, race, sex, age, arrest date, held-for agency, hold reasons, cell block, and release date field if applicable. The portal uses age instead of a full date of birth, and booking number, height, weight, eye color, hair color, and court date were not confirmed in the public row sample.
| Field | What it shows |
|---|---|
| Mugshot | Booking photo when the public roster displays it. |
| Name | Full public name string. |
| Age | Age format, not full date of birth. |
| Arrest date | The booking or arrest date shown by the roster. |
| Held-for agency | The agency connected to the hold or custody reason. |
| Hold reasons | Charge, warrant, bond, judge, or setter-style text when visible. |
| Release date | A field exists, but current-custody samples may be blank. |
Marshall County Jail vs Prison
County jail, state prison, federal prison, and immigration detention are different custody systems. A Marshall County arrest can begin at the jail, but a sentence or detainer can move the person elsewhere. Searchers often fail because they keep checking one system after the person has moved.
| Custody type | Who it covers | Where to search |
|---|---|---|
| Marshall County Jail | Current jail detainees, local sentences, warrants, holds, and recent bookings | County Zuercher roster |
| Iowa DOC | Sentenced state prisoners and community-corrections records | Iowa Offender Search |
| Federal BOP | Sentenced federal inmates from 1982 forward | BOP inmate locator |
| ICE | Current ICE custody or CBP custody after more than 48 hours | ICE Online Detainee Locator |
Marshall County Detention Facilities
Only one local detention facility was found in official Marshall County sources. The primary jail is the local hub for adult county custody. State, federal, and immigration searches are still important, but they are outside the county facility map unless the person is physically housed in the county jail on another agency's hold.
- Marshall County Jail holds adult county jail detainees, local sentences, court commitments, warrants, and other agency holds when housed locally.
The Iowa Offender Search screenshot captured for the project shows the statewide DOC fields used after a person leaves the county jail for state custody. The Iowa Offender Search source is separate from the Marshall County roster.
Marshall County Inmate Population FAQ
How big is the Marshall County inmate population?
The official local capacity figure is 182 beds at Marshall County Jail. The research did not find a current official average daily population or annual booking total in static county sources. Use the live roster for a current custody search and ask the sheriff's office for a date-specific count.
How do I search the Marshall County inmate population?
Start with the sheriff's Zuercher inmate list. If no current jail result appears, check Iowa Courts Online for the court case, Iowa Offender Search for a state sentence, BOP for sentenced federal custody, ICE for immigration custody, or call the jail.
Are mugshots part of the roster?
Yes, the public roster configuration includes a mugshot column, and sample public data included booking-photo image data. Juvenile display is restricted, and a photo may no longer show after release or record removal from the live roster.
Can VINELink tell me about release?
The sheriff FAQ points users to Iowa VINELink from the inmate record while the person is in custody. VINELink is a notification channel for release or transfer, not the full jail roster.
