Waltham Jail Roster Database

Waltham is a Middlesex County city, and anyone arrested there who is kept in custody goes to the Middlesex County jail in Billerica. Waltham does not have its own jail. The city police make arrests, and the county sheriff runs the detention facility. This page explains how to look up the Waltham jail roster through the Middlesex County system, how to request records from the police department, what to expect from the online inmate locator, and where to turn if county records don't have what you need.

Waltham Police Department

The Waltham Police Department is located at 155 Lexington Street, Waltham, MA 02452. The main number is (781) 314-3600. The department's website is at city.waltham.ma.us. Waltham Police handle all law enforcement matters within the city, including arrests that may lead to county detention.

When an officer in Waltham arrests someone and the person does not get released on the scene, they are processed locally and then transferred to the Middlesex County facility in Billerica. The city police keep their own copy of the arrest report, field notes, and any associated documentation. That record does not follow the person to the county jail. It stays with the Waltham Police Department.

If you need an arrest report or an incident report tied to a Waltham arrest, contact the police department's records office. A written public records request under M.G.L. c. 66, § 10 is the standard route. Include the person's name, the date of the incident, and your contact information. The department has ten business days to respond under state law.

The Waltham Police Department site includes department resources and contact details for public inquiries. Use the site to find guidance on records requests and department contacts.

Middlesex County Jail Search

The Middlesex County Sheriff's Office operates the facility at 269 Treble Cove Road, Billerica, MA 01862. This is where Waltham arrests end up when someone is held in custody. The sheriff's main phone is (978) 667-0700. The website is at middlesheriff.com.

Use the Middlesex County inmate locator to search the jail roster by name. Results show current custody status, booking date, charges, bail amount, and next court date. The data reflects real-time status, so if someone was released recently, they may not appear. In that case, call the main line at (978) 667-0700 to ask directly. Staff can look up custody status by name or booking number.

The sheriff's site also has information on visiting procedures, inmate phone access, and how to send mail to the Billerica facility. Review those policies before visiting, as hours and rules can change.

Note: If a search returns no results, it may mean the person was never held, was quickly released, or has been transferred to state custody. Each of these situations calls for a different next step.

What the Waltham Roster Includes

The Middlesex County inmate locator pulls from the jail's booking database. For anyone arrested in Waltham and held, the online record will typically show their full name, the date they were booked into the facility, the charges they are being held on, any bail amount set at arraignment, and the date of their next court appearance. This is a useful starting point for anyone trying to locate a person or understand their legal situation.

The roster does not include the full narrative of what happened during the arrest. It does not have the officer's field notes, the names of complainants, or documentation from the scene. Those details are in the arrest report, which lives with Waltham Police. The jail record is about custody, not the underlying incident.

Court records that flesh out the charges and case history are available through MassCourts. Waltham cases are handled in Waltham District Court and Middlesex Superior Court for more serious charges. MassCourts lets you search by name and find all related case filings and hearing dates.

State Custody and DOC Records

The Middlesex County jail holds people who are awaiting trial or serving sentences of two and a half years or less. If someone is convicted and sentenced to a longer term, they leave the county system and move to a state prison. Once that happens, they no longer appear in the Middlesex County roster.

To find someone in state custody, use the Massachusetts DOC Inmate Search. The Department of Correction maintains this database and updates it separately from county records. You can search by name and see what facility someone is in, what they were convicted of, and their projected release date where available.

Between the county inmate locator and the DOC database, you can account for virtually anyone in custody in Massachusetts. Start with the county search. If nothing comes up, check the DOC. If neither returns results, the person may have been released or may be in federal custody rather than state or county.

Public Records in Massachusetts

Both the Waltham Police Department and the Middlesex County Sheriff's Office are government agencies subject to the Massachusetts public records law. Under M.G.L. c. 66, § 10, any person can request to inspect or copy public records held by a government agency. Jail rosters and arrest logs are generally public records. Some items may be withheld under specific exemptions, but routine booking information is typically available.

If your request is denied, the Massachusetts Public Records office can help. They provide guidance on appealing a denial and can mediate disputes. Most standard jail roster and arrest record requests do not get to that point, but it is an option if needed.
