Middlesex County Jail Roster

The Middlesex County jail roster is managed by the Middlesex County Sheriff's Office and gives the public a way to search for people currently held at the county's correctional facilities. As the most populous county in Massachusetts, Middlesex holds a large daily inmate population across its facilities in Billerica. You can search by name, leave fields blank to view all current inmates, or use partial names to narrow results. This page covers how to use the online inmate locator, how to contact the Sheriff's Office, and what steps to take if you need official records from Middlesex County.

Online Inmate Search for Middlesex County

The Middlesex County Sheriff's Office runs a real-time inmate locator at middlesheriff.com/services/inmate-locator. The system updates continuously as bookings, transfers, and releases happen. You do not need to create an account or pay any fee to use it. The search is not case-sensitive, so you can type a name in any format.

If you only know part of a name, partial name searches work. You can also leave all fields blank and submit the form to see every person currently in Middlesex County custody. This is useful when you are not sure of the exact spelling. Results come back sorted by name and include a full set of details for each person found.

Each record in the roster shows the full name, date of birth, current housing facility and unit, booking date, commitment date, charges, bail or bond amount, court of jurisdiction, next court date, projected release date, and any hold status. That level of detail makes this one of the more complete inmate search tools available through a Massachusetts county sheriff. If the person you are looking for does not appear, they may be housed in a different facility, held federally, or may have already been released.

Sheriff's Office Contact and Location

The Middlesex County Sheriff's Office is located at 269 Treble Cove Road, Billerica, MA 01862. The main phone number is (978) 667-0700. You can reach the office through the contact page at middlesheriff.com/contact. The office handles all bookings, holds, and transfers for people in Middlesex County custody.

Sheriff Peter J. Koutoujian leads the department. His office oversees the correctional facilities, inmate services, and public records access. If you have a question that the online locator does not answer, calling the main line is the fastest way to get help. Staff can confirm whether someone is in custody, what facility they are at, and whether they have a scheduled court date.

Visiting Inmates at Middlesex County Facilities

Visits to Middlesex County correctional facilities are by appointment. To schedule a visit, call the main number at (978) 667-0700 and ask for extension 2200. Walk-in visits are not accepted. All visitors must be approved in advance, and there are rules about what you can bring and how long a visit lasts.

Full visiting information, including approved items, dress code, and scheduling details, is posted at middlesheriff.com/services/visiting-information. Check this page before you go, since visiting hours and procedures can change. Children who visit must be accompanied by an approved adult. The inmate services section of the website at middlesheriff.com/services/inmate-services also covers programs, commissary, and communication options for people in custody.

Not all facilities have the same visiting hours. Confirm which facility your contact is assigned to before scheduling. The online inmate locator will show the current housing facility and unit, which helps you get the right information when you call to book a visit.

Requesting Records from Middlesex County

Public records from the Middlesex County Sheriff's Office fall under M.G.L. c. 66, § 10, which is the Massachusetts public records law. This statute gives any person the right to request records held by a public agency, including a county sheriff's office. Requests must be made in writing, and the agency has 10 business days to respond.

The Records Access Officer for Middlesex County is Megan McLatchey. You can reach her at 781-960-2830. When you submit a request, be as specific as possible about the records you want. Include dates, names, and any case or booking numbers you have. Vague requests take longer to fulfill and may result in a response asking for clarification.

Records you might request include booking records, incident reports, classification records, and release records. Some records may be withheld if they fall under an exemption in the public records law, such as records that could interfere with an active investigation or records that contain personal information protected by law. The agency must tell you the reason if they withhold or redact any records.

The Massachusetts Public Records Division at mass.gov/public-records can help if your request is denied or if you believe the agency is not responding properly. They offer guidance on how to appeal a denial.

The Massachusetts public records portal gives an overview of your rights under state law.

Using that portal, you can find forms, instructions, and contact information for the Public Records Division, which oversees compliance across all state and county agencies including the Middlesex County Sheriff's Office.

State Sentences and DOC Inmates

The Middlesex County jail roster only covers people held at county facilities. People sentenced to more than two and a half years are typically sent to a state prison run by the Massachusetts Department of Correction, not the county jail. County facilities hold people who are awaiting trial, serving shorter sentences, or being held on a detainer or warrant.

If someone you are looking for is not in the Middlesex County roster, they may be in state custody. The DOC runs a separate inmate search at publicsearch.doc.state.ma.us. This tool covers all state prison facilities across Massachusetts. The Massachusetts DOC is governed by M.G.L. c. 127, which sets out rules for state correctional institutions, inmate rights, and release procedures.

County correctional facilities in Massachusetts operate under M.G.L. c. 126. This statute covers how county jails and houses of correction are run, who has oversight, and what standards they must meet. Understanding the difference between county and state custody helps you look in the right place when searching for someone.

For victim notification, the VINELink system at vinelink.com lets you register to get alerts when an inmate's status changes. This service is free and covers both county and state facilities in Massachusetts.
