This blog post explains how the Massachusetts statewide grand jury works and why it is used in certain criminal cases. It breaks down what makes a statewide grand jury different from a regular county grand jury, the types of cases it handles, and the powers it has during an investigation. It also outlines what defendants and witnesses should know if they become involved, including their rights and what to expect if an indictment is issued.
What Is the Massachusetts Statewide Grand Jury?
The Massachusetts statewide grand jury is a special grand jury that the Attorney General (AG) can convene to investigate and indict crimes across the entire state. Unlike ordinary county grand juries (which only have authority within one county), a statewide grand jury has jurisdiction throughout Massachusetts.
This means the AG can bring evidence and witnesses from multiple counties into one proceeding, before one grand jury, instead of needing separate grand juries in each county.
The Massachusetts AG typically uses the statewide grand jury for cases that span several counties or are too expansive for a single county’s jurisdiction. It serves as a powerful tool to streamline complex investigations under one roof, ensuring a coordinated approach when crimes cross county lines.
Notably, a statewide grand jury can sit for an extended term to allow time for lengthy, multi-jurisdictional investigations, compared to the shorter terms of county grand juries.
In essence, the Massachusetts AG’s statewide grand jury combines the investigative powers of a grand jury with a state-wide reach, making it especially useful for tackling wide-ranging criminal schemes.
When Is the Statewide Grand Jury Used, and What Cases Does It Handle?
The statewide grand jury is reserved for significant or complex crimes that often involve multiple jurisdictions. The AG’s Office often relies on this mechanism for cases such as large-scale conspiracies or crimes affecting multiple communities.
For example, statewide grand juries have been used to prosecute:
- Human trafficking rings operating across several counties
- Drug trafficking networks that span different regions of Massachusetts
- Organized theft or fraud schemes (e.g. theft rings, forgery or financial crimes hitting various counties)
- Complex white-collar crimes and cybercrimes that have victims or evidence in multiple areas
Using a single statewide grand jury for these situations is efficient and ensures consistency. It avoids the need for duplicate presentations to separate county grand juries, and it enables one group of 23 jurors to see the full picture of a widespread crime network.
The statewide grand jury’s indictments are returned in the county where the grand jury sits (Suffolk County) and then the case is transferred to an appropriate county for arraignment and will live there for the remainder of the prosecution.
For trial purposes, venue can be any county where the offense could normally be prosecuted, so defendants are ultimately tried in a proper location tied to the crime.
Powers and Process of the Statewide Grand Jury
In terms of powers, the statewide grand jury operates much like a regular grand jury, but on a broader scale.
It can:
Subpoena witnesses and documents from anywhere in Massachusetts
Compel testimony
Review evidence to determine if probable cause exists to issue criminal indictments
The proceedings are secret, as with any grand jury, to protect the investigation’s integrity and the privacy of those involved.
The AG (represented by Assistant Attorneys General) runs the show, presenting evidence and questioning witnesses, and has the same authority in a statewide grand jury as a District Attorney would in a county grand jury.
The rules of evidence are relaxed in grand jury settings, so hearsay or secondary evidence can be considered, and only the prosecution’s side is presented (defendants and defense lawyers are almost never present during grand jury proceedings).
Ultimately:
If at least 12 of the 23 grand jurors vote in favor, the grand jury returns a “true bill” (indictment)
If the evidence is deemed insufficient, they may return a “no bill,” and no indictment issues
The Massachusetts statewide grand jury thus serves both as an investigative arm and as a screening mechanism to confirm there’s enough evidence to proceed with felony charges.
Key Considerations for Defendants and Witnesses
For individuals caught up in a statewide grand jury investigation, the experience is similar to any grand jury, but with the Attorney General’s involvement and a potentially wider scope.
For Witnesses
Witnesses subpoenaed to testify must appear. Ignoring a grand jury summons can result in the government seeking a warrant for arrest.
However, witnesses do have rights:
A witness may hire an attorney for advice and support
Witnesses can invoke the Fifth Amendment privilege against self-incrimination
If there’s a dispute (for example, a witness refuses to testify citing a privilege), a judge will resolve it at something called a Martin hearing.
Depending on the situation:
The witness could be compelled to testify, or
The government may need to consider a grant of immunity to overcome the privilege
It’s wise for any witness to consult with a lawyer beforehand to understand their rights.
For Defendants or Potential Targets
Defendants or potential targets of a statewide grand jury should be aware that these proceedings are one-sided and secret.
You typically will not be notified of a grand jury investigation against you unless:
The AG’s office issues a target letter, or
You are invited to testify (rare)
The grand jury hears only the prosecution’s evidence, without any defense input.
If you are later indicted, you will receive a transcript of all the testimony and evidence presented (the “grand jury minutes”) as part of discovery. This allows your defense team to review what was said about you behind closed doors.
An indictment is not a conviction. It simply means the grand jurors found probable cause to charge you. You remain innocent unless proven guilty at trial.
However, being indicted by the statewide grand jury often signals that the case is complex or far-reaching, and these cases are usually handled by seasoned prosecutors in the AG’s office. Anyone indicted should seek experienced legal counsel familiar with Massachusetts statewide grand jury practice.
Summary: Why the Massachusetts Statewide Grand Jury Matters
In summary, the statewide grand jury in Massachusetts is a unique grand jury system that strengthens the Attorney General’s ability to tackle multi-county and large-scale crimes.
It differs from county grand juries by its statewide reach and use in specialized situations, but it follows a similar grand jury process.
By presenting evidence to a single grand jury for an entire investigation, the Massachusetts AG’s statewide grand jury aims for efficiency and consistency in charging decisions.
For the public, this means that complex criminal enterprises—whether a drug ring spanning Essex and Middlesex Counties or a fraud scheme hitting victims across the state—can be addressed in a unified way.
For defendants and witnesses, it’s important to understand how this process works: its broad authority, secret proceedings, and the rights you retain if you find yourself involved.
Despite its expansive scope, the statewide grand jury remains grounded in the fundamental concept of probable cause review, serving as both a shield and a sword in the Commonwealth’s justice system.
