How the Jail System Works for Warren

When someone is arrested in Warren, they may be held briefly at the Warren City Jail for processing before transfer to the Macomb County Jail. The county jail is the main detention facility for pre-trial detainees and those serving short sentences in Macomb County. People serving sentences of more than a year after a felony conviction are sent to a Michigan Department of Corrections facility and won't appear in the county system.

If you're not sure which system to check, start with the Macomb County inmate locator. If no record appears, check Michigan OTIS. If still nothing shows up, the person may have been released or transferred to federal custody. Federal detainees appear in the Federal Bureau of Prisons locator, which operates separately from state systems.

Michigan OTIS for State Prison Inmates

The Michigan Department of Corrections Offender Tracking Information System, known as OTIS, covers all MDOC-supervised offenders statewide. You can search by name or MDOC number at mdocweb.state.mi.us. Results include the person's current facility, offense details, and projected release dates where applicable. OTIS also shows people under parole or probation supervision in the community, so not every result means the person is currently incarcerated. Check the custody field in the results to confirm placement. The MDOC website at michigan.gov/corrections has further information on the state corrections system.

VINELink Victim Notification

Macomb County is connected to the VINELink statewide victim notification system. You can register at vinelink.com or call 1-800-770-7657 to get alerts when an inmate's status changes. The service is free and sends notifications by phone, text, or email. You don't need to be a crime victim to register. The service is open to anyone who needs to track a specific inmate's release, transfer, or bond change. Alerts go out automatically when a change is recorded in the system.

Requesting Records Under MCL 15.231

Michigan's Freedom of Information Act at MCL 15.231 lets you request records from public agencies. You can submit a FOIA request to the Macomb County Sheriff's Office or the Warren Police Department for booking logs, incident reports, and jail records. Requests must be in writing. Agencies have five business days to respond. Fees may apply based on the volume of records requested. Basic inmate status information is available for free through the online locator without a formal request.

MiCOURT Case Records

Court cases filed after an arrest in Warren appear in Michigan's court case search system at courts.michigan.gov/case-search. MiCOURT covers courts statewide. Warren cases are heard in Macomb County's 16th Circuit Court for felonies and the 37th District Court for misdemeanors and civil matters. You can search by name or case number to find charges, hearing dates, bond amounts, and case outcomes. Court records are separate from jail records but provide important context about why someone is in custody and what stage their case is at.

Michigan State Police Tools

The Michigan State Police Internet Criminal History Access Tool (ICHAT) at michigan.gov/msp/services/ichat provides statewide criminal conviction records for a small fee. It's separate from the jail lookup and is useful when you need a more complete criminal history rather than just current custody status. The Michigan Sex Offender Registry at michigan.gov/msp/services/sex-offender-registry is free and searchable by name or location. Neither tool confirms whether someone is currently in jail. For current custody, use the Macomb County inmate locator or OTIS.

Visiting Inmates at Macomb County Jail

Visitation at the Macomb County Jail requires prior scheduling. The facility uses a video visitation format. Call the Macomb County Sheriff at 586-469-5151 to get the current schedule and to find out how to get on an approved visitor list. All visitors must show valid ID. Remote video visits may be available through a third-party provider for an additional fee. Walk-in visits without prior approval are generally not permitted. Policies are subject to change, so it's worth confirming details by phone before making a trip.

County Jail vs. State Prison

Knowing the difference saves time in your search. County jails, like the Macomb County Jail, hold people who are newly arrested, waiting for trial, or serving short sentences. People convicted of felonies with sentences over one year are sent to state prisons run by MDOC and won't appear in county systems. Under MCL 801.1, county jails fall under the county sheriff. Under MCL 800.31, state prisons are managed by MDOC. Each has its own lookup tool. Check both if you're not sure where to find someone.

The screenshot below shows the Michigan OTIS interface, which provides statewide inmate population data for individuals serving time in state prisons, including those from Warren and Macomb County.

OTIS is the official state tool for searching Michigan prison inmates from Warren and across Macomb County. Use it when county records don't show the person you're searching for.
