Checking St. Louis County Criminal History
No single search supplies a complete St. Louis County criminal history. Begin with the question you need answered. Filed charges, hearing dates, judgments, and sentences belong in Missouri Case.net. Current county custody belongs in the Justice Services inmate locator. A statewide Missouri open-record response comes from MACHS, while a police narrative must be requested from the department that investigated the event. Full names, dates of birth, case numbers, report numbers, and likely agencies help separate people with similar names.
Use the narrowest reliable identifier first. A court case number is stronger than a common surname, and fingerprints are stronger than a name match. St. Louis County has many city departments, so the arresting agency matters just as much as the place of booking.
- Search Case.net and select the 21st Judicial Circuit for filed criminal cases.
- Check the county inmate locator when present custody at the Buzz Westfall Justice Center is the issue.
- Order a MACHS name check for Missouri open-record history, or use fingerprints for your own identity-confirmed review.
- Request the underlying incident or arrest report from the police agency that created it.
- Use MODOC Offender Search if state prison, probation, parole, or conditional release may apply.
Match St. Louis County Record Searches
Three official systems often appear beside each other, yet they answer different questions. Case.net is the judicial file. The county locator is a custody snapshot. MACHS is a statewide repository product built from agency submissions. Their results can differ without any system being wrong because each one records a different point in the process.
Case.net is best for filed charges, docket events, outcomes, and sentences, but it is not the police report or a full rap sheet. The county inmate locator answers current or recent Justice Services custody questions, not lifetime history. MACHS supplies Missouri open-record history, with name results treated as possible matches. MODOC Offender Search covers state prison and supervision status rather than every county arrest.
The official MACHS landing page shows the choice between name and fingerprint channels.
That split is important: a quick name result and a fingerprint-confirmed self-review do not carry the same identity assurance.
Missouri Official Background Checks
The Missouri State Highway Patrol Criminal Justice Information Services Division maintains the Central Repository. Any member of the public may request a name-based check through the Missouri Automated Criminal History Site. The published charge is $15 plus the state payment-processing fee. Its open-record response can include convictions, arrests less than 30 days old, prosecutor-filed charges awaiting final disposition, and an active-probation suspended imposition of sentence. MSHP warns that a name result is only a possible match.
For self-review, the stronger path is MACHS Fingerprint Search through IDEMIA/IdentoGO capture sites. Register in the official portal or call IDEMIA at 844-543-9712. Fingerprints tie the request to identity, and ordinary results generally arrive by mail in seven to ten business days. Statutory authority controls access to closed Missouri and FBI material.
| Product | Identity | Published fee |
|---|---|---|
| MACHS name check | Name and identifiers | $15 plus processing |
| Missouri fingerprint check | Fingerprints | $20 plus $12 vendor fee |
| Authorized Missouri and FBI check | Fingerprints | $20, $13.25, and $12 vendor fee |
| Notarized response | Add-on | $5 |
Inside a St. Louis County MACHS Search
MACHS registration leads to a search form that uses legal name and date of birth, with added identifiers available to narrow the match. Wrong data entered after submission does not bring a refund. Most name searches return to the account at once, but MSHP says a response that needs research can take 10 to 14 business days.
| Field | Required | Use |
|---|---|---|
| Last and first name | Yes | Core legal-name match |
| Middle name | Not stated | Helps narrow a common name |
| Date of birth | Yes | Core identifier |
| Social Security number | Optional when available | Use only in the secure official portal |
| Sex and race | Portal dependent | Additional match details |
| Notarized response | No | Adds certification and a $5 charge |
The official MACHS name-search interface is the source for this statewide option.
Review each identifier before payment because the portal treats the submitted search as final.
Criminal Record Types
St. Louis County criminal records are created at several stages. Police make an incident or arrest report. Justice Services makes a booking record when a person enters county detention. The Prosecuting Attorney and clerk create the filed case trail, while MSHP links reported arrest cycles and dispositions in the Central Repository. MODOC takes over state custody and supervision information.
- Police report: reported facts, officer narrative, people, legal basis, and evidence held by the investigating agency.
- Booking record: intake time, booking identifier, fingerprints, custody charges, holds, bond, and release information.
- Court file: filed charges, motions, hearings, pleas, judgment, sentence, and financial entries held by the clerk.
- Repository record: fingerprint-linked arrest cycles and submitted dispositions across Missouri.
- Corrections record: state prison, probation, parole, and conditional release information maintained by MODOC.
Warrants require their own fallback chain. Check the Case.net docket, ask the issuing court clerk, and contact the agency with jurisdiction. The St. Louis County Sheriff warrant line is 314-615-8899, but sealed or unserved material may not be public.
Three St. Louis County Identifiers
A booking number, an Offense Cycle Number, and a court case number should not be merged. Justice Services assigns the local booking identifier. The fingerprint card sent to MSHP receives an eight-digit OCN that tracks an arrest cycle in the state repository. The circuit or municipal clerk assigns a case number when a matter reaches court. One arrest can therefore produce all three.
- Booking number
- The county detention identifier used for intake, custody, bond, and release records.
- OCN
- The eight-digit state tracking number attached to a fingerprinted arrest cycle and later disposition reports.
- Case number
- The clerk's identifier for filed charges, docket events, documents, judgment, and sentence.
- SIS
- A suspended imposition of sentence, where the court withholds imposing sentence while probation is completed.
- SES
- A suspended execution of sentence, where a sentence exists but is not executed during probation.
When records conflict, compare identifiers and dates before assuming they refer to the same person or event.
Inside a St. Louis County Criminal Record
The contents depend on the custodian. A jail result focuses on custody. A court file focuses on the case. A rap sheet organizes identity and OCN-linked arrest cycles. Reading the label on each field prevents a booking allegation from being mistaken for a filed charge or final conviction.
| Name and identifiers | Names, aliases, birth data, state identifiers, and match details allowed in that product. |
|---|---|
| Arrest and booking | Arrest date, agency, intake charge, booking number, holds, bond, custody, and release. |
| Charges and statutes | Arrest labels or separately filed counts, Missouri code cites, and offense classes. |
| Disposition | Conviction, dismissal, acquittal, nolle prosequi, SIS, or another count-specific result. |
| Sentence | Custody term, probation, fines, restitution, and concurrent or consecutive treatment where public. |
| Supervision | Public prison, probation, parole, conditional-release, and status entries reported by MODOC. |
Read each charge line. One St. Louis County case may contain several counts with different outcomes, so the case status alone cannot establish the result of every charge.
St. Louis County Records in Clayton
The county's key record offices sit close together in Clayton, but proximity does not create one records counter. Court files are at the St. Louis County Courts Building. Charging-office material belongs to the Prosecuting Attorney. Booking and custody records belong to Justice Services across the justice campus. Police reports stay with the police agency that made them.

Request St. Louis County Police Records
Use the county's NextRequest Sunshine portal for an existing record held by county Police, Justice Services, the Prosecuting Attorney, or another county department. Describe the record, date range, event or case number, location, likely custodian, and the exact product requested. An email address links the request to a portal account.
The portal is a fallback, not a substitute for choosing the right office. A Florissant Police report must ordinarily go to Florissant, even when Justice Services later made a county booking.
Central Police Records is open Monday through Friday from 7:30 a.m. to 4:30 p.m. Police and traffic reports are normally available ten days after the incident and cost $6.50. In-person pickup needs photo identification. A mailed request needs the details and notarized statement listed on the county form. The old county Police background-check counter ended service on January 16, 2025, so statewide checks now route to MACHS.
Public Access Laws in Missouri
Missouri Sunshine Law rules apply to many St. Louis County records, but each custodian may close material that fits a lawful exception. A public docket does not make every attachment public. Active investigative details, juvenile files, victim identifiers, sealed warrants, expunged matters, psychiatric evaluations, presentence reports, and probation or parole reports can remain closed or redacted.
Key Missouri rules:
Section 610.011 RSMo directs courts to read the Sunshine Law in favor of openness.
Sections 610.021 and 610.023 RSMo cover permitted closures, custodians, and request responses.
Section 610.100 RSMo sets access and closure rules for arrest and incident records.
Section 43.540 RSMo governs Central Repository dissemination and charges.
Court Operating Rule 2 governs public access to Missouri judicial records.
A county body generally must produce the record or explain a delay by the end of the third business day. That response rule is not a promise that all production will finish in three days.
Keep St. Louis County Records Separate
The independent City of St. Louis is not part of St. Louis County. City police, City courts, and City detention records belong to different custodians. A search limited to the 21st Judicial Circuit should not be read as a search of the City's circuit. This distinction is one of the most common local errors.
County geography is fragmented too. Florissant and Chesterfield operate their own police departments and municipal courts. Wildwood receives police service through St. Louis County Police while keeping a municipal court. One event may lead to a city incident report, a county booking, a 21st Circuit case, and a state OCN record. Track the event through each custodian rather than searching by place name alone.
Sealed, Expunged, and Restricted Records
Missouri closes some non-conviction records and a completed SIS under sections 610.105 through 610.120, subject to exceptions. Expungement under section 610.140 is a separate petition process. Eligibility depends on the offense, history, prior relief, waiting rules, and completion of the sentence, probation, parole, fines, and restitution.
A St. Louis County petition must identify each case and name every agency that holds the record so the order can bind those custodians. Start by comparing Case.net and MACHS, then list the arresting agency, prosecutor, clerk, Central Repository, and corrections office involved. File in a court where the arrest, plea, trial, or conviction occurred. Missouri Courts supplies forms, but staff cannot give legal advice. Verify the current filing and service cost with the circuit clerk.
Closure or expungement limits ordinary public access. It does not erase every past event or guarantee that an old copy held elsewhere will vanish at once.
Track St. Louis County Custody Changes
The Buzz Westfall Justice Center locator answers whether a person is in county detention. It is not a prison search. After a state sentence or release to state supervision, use the MODOC Offender Search instead.
The state locator can show prison or supervision data, but it does not replace the St. Louis County court judgment or the county booking record. A practical flow is: arresting agency to Justice Services, then 21st Judicial Circuit, then MODOC if the sentence or supervision reaches the state system.
Missouri adult probation and parole are state-run. The Division of Probation and Parole serves local cases through St. Louis-area field districts, and the Missouri Parole Board handles parole authority. Public locator data can lag, while officer notes and risk or treatment records are not promised as open records.
Fingerprint St. Louis County Record Review
The MACHS Fingerprint Search Portal starts the identity-confirmed route for reviewing your own Missouri record.
After registration, choose an IDEMIA/IdentoGO capture site, make the appointment, and bring the accepted identification. IDEMIA takes and sends the prints but does not receive the result. MSHP mails the response.
If a name result belongs to someone else, the MSHP Criminal History Identity Challenge process can use fingerprints to separate identities. When an arrest or disposition is wrong, identify the agency or court that sent the data and provide the supporting document. MSHP maintains the repository, but the source agency may have to correct its submission.
St. Louis County Criminal Records by City
The three largest incorporated cities in the county are Florissant, Chesterfield, and Wildwood based on the common July 1, 2024 Census estimate. Their local channels differ. Florissant and Chesterfield keep their own police reports. Wildwood Police services route through St. Louis County Police. Each city also has a municipal court for local ordinance and traffic matters.
Florissant Criminal Records
51,290 residents · City Police and Municipal Court channels
Chesterfield Criminal Records
49,465 residents · City Police and Municipal Court channels
Wildwood Criminal Records
35,082 residents · County Police service and city Municipal Court
Municipal cases do not replace state criminal cases in the 21st Judicial Circuit. Search the issuing court, then check Case.net and contact the clerk if a citation or filed charge is absent.
St. Louis County Probation Records
MODOC's District EP profile gives local context for the state supervision structure serving St. Louis City and County.
The combined service area is another reason to verify jurisdiction. A St. Louis County circuit judgment, a MODOC locator result, and a field-office record can document separate parts of probation or parole.
Read Case.net for the sentence entered by the court. Use MODOC Offender Search for public supervision status, then contact the assigned field office for a current status question. MODOC's published intervention fee is $30 per month. Records requests for releasable corrections material go to the division's Sunshine custodian, not the county police or circuit clerk.
