When someone is accused of a violent crime in Arizona, the case may begin through one of two legal processes — a grand jury indictment or a direct complaint. Understanding how grand jury indictments work is critical because the process occurs behind closed doors and often determines whether a person will face felony prosecution in court.
At Guardian Law, our criminal defense attorneys represent individuals in Peoria and across Arizona who are being investigated or have already been indicted by a grand jury. We help clients understand the process, protect their rights, and begin building a strong defense from day one.
What Is a Grand Jury Indictment?
A grand jury indictment is a formal charge issued by a panel of citizens who determine whether enough evidence exists to proceed with a criminal case. In Arizona, a grand jury typically consists of 12 to 16 people selected from the community.
Unlike a trial, a grand jury does not decide guilt or innocence. Instead, it decides whether there is probable cause to believe a crime occurred and that the accused person committed it. If the jury finds probable cause, they issue an indictment, which officially begins the felony case in Superior Court.
How the Grand Jury Process Works
The grand jury process happens privately, without the presence of the defendant or their attorney. Prosecutors present evidence, question witnesses, and summarize their theory of the case. Because this process is one-sided, it can heavily influence the direction of the case from the very start.
Key Steps Include
- Prosecutor’s Presentation: The state presents police reports, witness testimony, and other evidence to the jurors.
- Witness Testimony: Law enforcement officers or other witnesses may testify under oath.
- Legal Instructions: The prosecutor explains relevant Arizona laws and possible charges to the jurors.
- Deliberation and Vote: After hearing the evidence, the jurors deliberate privately. If at least nine jurors agree that probable cause exists, an indictment is issued.
Once the indictment is returned, the case moves to the arraignment stage, where the defendant enters a plea and the court sets further hearings.
Why Prosecutors Use Grand Jury Indictments
Prosecutors in Maricopa County and across Arizona often prefer grand jury indictments for violent crime cases because the process is faster and gives them more control.
Common Reasons Include
- The evidence is strong, and they want to move the case forward quickly.
- They prefer to avoid cross-examination of witnesses at a preliminary hearing.
- The case involves complex or sensitive evidence, such as homicide or aggravated assault.
- They want to protect witnesses or victims from testifying early in the case.
Because the defense cannot participate directly, indictments can be difficult to challenge later. However, skilled attorneys can file motions to correct or dismiss an unfair indictment under Arizona law.
Violent Crimes Commonly Presented to a Grand Jury
Grand juries are commonly used for serious or high-profile violent crimes that carry long prison sentences. These include:
- Aggravated assault or assault with a deadly weapon
- Armed robbery
- Kidnapping
- Homicide or manslaughter
- Drive-by shooting
- Home invasion
- Weapons misconduct connected to violent offenses
Because these charges often include firearm enhancements or dangerous offense designations, an indictment can expose defendants to mandatory prison time if convicted.
How a Grand Jury Differs from a Preliminary Hearing
Both grand jury proceedings and preliminary hearings serve the same purpose — to determine whether there is probable cause to move a case forward. However, the key difference lies in who participates.
- In a preliminary hearing, the defense can attend, cross-examine witnesses, and challenge the evidence in open court.
- In a grand jury, the process is closed, and the defense has no right to participate or present evidence.
Because of this, prosecutors often choose a grand jury when they want to secure an indictment without exposing their witnesses or evidence to early scrutiny.
Can a Grand Jury Indictment Be Challenged?
Yes. Although the process is secret, your attorney can review the grand jury transcript and determine whether the proceeding was unfair or legally improper. If the prosecutor gave misleading legal instructions or withheld key evidence, your lawyer can file a motion to remand — a request for the court to send the case back for a new grand jury review.
These challenges are time-sensitive and must be filed promptly after the indictment. Therefore, hiring an attorney as soon as you learn about an indictment or investigation is essential.
What to Do If You Are Under Investigation
If law enforcement contacts you about a violent crime investigation, assume that prosecutors may be preparing to present your case to a grand jury. Do not speak to police or investigators without legal counsel. Anything you say can be used before the grand jury as evidence.
Instead, contact an experienced defense lawyer immediately. Your attorney can communicate with prosecutors on your behalf, gather information about the investigation, and start building your defense early — before charges are even filed.

Frequently Asked Questions (FAQ)
Can I testify before the grand jury?
In most cases, defendants do not testify. However, your attorney may request that you be allowed to present limited testimony. The decision ultimately rests with the prosecutor and the jurors.
Will I be notified before the grand jury meets?
Not always. Many defendants learn about their indictment only after the jury returns it. That is why seeking counsel early in an investigation is so important.
What happens after an indictment?
Once you are indicted, you will be scheduled for an arraignment. At that hearing, you enter a plea, and the court sets future dates for discovery, motions, and trial.
