Finding arrest logs or criminal history data in the Commonwealth requires navigating a strict legal framework rather than simply running a casual online search. Unlike states where local police blotters and arrest records are openly searchable online via public databases, Massachusetts handles criminal data through a centralized system known as CORI (Criminal Offender Record Information).
If you're trying to look up someone's background, understand your own rights, or find police logs, you won't find a single free website hosting every historical arrest. Instead, public access is heavily regulated by state statutes managed through the Department of Criminal Justice Information Services (DCJIS).
How Massachusetts Arrest Records Differ From Other States
In many jurisdictions, a local police department publishes every booking photo and arrest report directly to a public web portal. Massachusetts operates differently. Standing alone, an arrest record or booking log is not automatically a matter of permanent public record in the state's centralized criminal database.
Under Massachusetts law, criminal history information compiled by justice agencies is restricted to court-generated material stemming from an arraignment. If someone is arrested by the police but released without charges ever being filed, or if a case is dismissed prior to arraignment, it generally does not enter the standard CORI system. Further journalism by Bloomberg highlights comparable perspectives on this issue.
Police departments do maintain local daily logs of calls and arrests, which are public under the state’s Public Records Law. However, these logs are typically restricted to recent events, often kept available only for a brief window at the local station house rather than archived in a permanent, searchable statewide digital index.
The Role of iCORI and Public Access Levels
The primary gateway for checking criminal history in the state is the Massachusetts iCORI system managed by the DCJIS. However, general public access—known legally as Open Access—is heavily restricted compared to what employers, housing providers, or law enforcement agencies can see.
Under Open Access rules available to everyday residents, you cannot simply look up any person's complete history. Instead, public lookups are limited to specific, recent conviction data:
- Misdemeanor convictions for up to one year following the date of disposition or release.
- Felony convictions punishable by less than five years in prison for up to two years post-disposition.
- Serious felony convictions (punishable by five or more years) or specific homicide and sex offenses for up to ten years, unless sealed.
- Pending criminal charges do not appear under basic public open access.
If you need deeper background checks for employment, housing, or licensing, you must qualify for Standard Access or Required Access levels under state regulations, which require registration, approved justifications, and user fees.
Requesting Your Own Record or Police Logs
If you are looking up your own history or dealing with a specific local incident, the process changes entirely.
Accessing Your Personal CORI
You have an absolute right to inspect and copy your own complete criminal record. A personal request has no lookback restrictions and displays all unsealed convictions, non-convictions, and pending cases.
- Create an account on the official DCJIS iCORI Portal.
- Verify your identity using a valid Massachusetts driver's license or state ID.
- Pay the standard processing fee (currently $25), unless you qualify for an indigency waiver based on public assistance or low income.
Obtaining Local Police Logs
If you need information about a recent arrest handled by a specific municipality, you can submit a public records request directly to that city or town's police department. Under the Massachusetts Public Records Division guidelines, municipal records access officers must respond to requests within ten business days. Keep in mind that active, ongoing police investigations may be legally withheld from public logs until the investigative process concludes.
Privacy Rights and Sealing Criminal Records
Because past arrests and charges can disrupt employment and housing opportunities, Massachusetts provides legal mechanisms to shield old records from public view. This process is called sealing.
Once a record is sealed, it is hidden from standard public and employer background checks, and you can legally answer "no record" on most job applications. Waiting periods depend on the disposition of the case:
- Dismissals and Non-Convictions: Can often be sealed immediately or relatively quickly through a petition to the court.
- Misdemeanor Convictions: Generally eligible for sealing after five years of clean history following the completion of any sentence or probation.
- Felony Convictions: Generally eligible for sealing after ten years of clean history.
Petitions must be filed through the specific court where the original matter was adjudicated. For detailed legal aid resources on navigating this process, consult organizations like Massachusetts Legal Help.
Frequently Asked Questions
Can I look up someone's arrest records online for free in Massachusetts?
No comprehensive, free public database exists for instant arrest lookups in the state. While local police departments maintain daily blotters, statewide history requires going through the paid iCORI system, which restricts general public viewing to recent convictions.
Do dropped charges or dismissed cases show up on a CORI check?
They do not appear for standard public users or ordinary employers. However, criminal justice agencies, law enforcement, and certain specialized positions requiring Required Access can view non-convictions.
How long do convictions stay on your record before they can be sealed?
Misdemeanors require a five-year waiting period, while felonies require a ten-year waiting period following the completion of all sentencing, probation, or parole terms. Certain offenses, such as specific sex crimes or murder convictions, cannot be sealed.
What is the difference between sealing and expunging a record?
Sealing hides the record from public view and standard employers, though law enforcement can still see it. Expungement completely destroys and erases the record as if it never happened, though it is only available in very narrow circumstances, such as government error, identity theft, or specific minor offenses impacted by recent cannabis legalization reforms.
