The question of what happens with a hung jury has gained fresh attention as jurors in the Lindsay Clancy murder trial told a Massachusetts judge they could not reach a unanimous decision. Rather than immediately ending the trial, the judge instructed the jury to continue deliberating.
That development highlights an important point about American criminal trials: a jury reaching an impasse does not automatically mean the case is finished. A judge may give jurors additional time, provide further instructions and determine whether continued deliberations could produce a verdict. Only after the court concludes that the jury cannot reach the required decision can a mistrial become the next step.
A deadlocked jury also does not equal an acquittal. The defendant has not been convicted, but the prosecution may still have the ability to pursue the unresolved charges in another trial.
What Is a Hung Jury?
A hung jury occurs when jurors cannot reach the agreement required to issue a verdict. In many serious criminal cases, that means the jurors cannot unanimously decide whether the defendant is guilty or not guilty.
Jurors can disagree for many reasons. They may interpret testimony differently, have conflicting views about physical evidence or reach different conclusions about whether prosecutors proved an essential element of a crime.
The disagreement itself does not determine the outcome.
A jury may initially report that it is struggling but later reach a verdict. For that reason, courts generally distinguish between a jury that is having difficulty and one that is genuinely unable to reach a decision.
The judge ultimately determines whether the deliberations should continue or whether the jury has reached an impasse.
Why a Jury Deadlock Does Not Immediately End a Trial
When jurors say they cannot agree, the judge does not necessarily declare a mistrial immediately.
The court can ask jurors to continue deliberating. This gives them additional time to review testimony, examine admitted evidence and discuss the legal instructions governing the case.
Judges have discretion over how long deliberations should continue. There is no universal number of hours or days that automatically creates a deadlock.
A complicated trial may require extensive deliberation because jurors must consider numerous witnesses, documents, exhibits and legal questions.
A shorter trial may reach a decision much faster.
The key issue is whether there remains a reasonable possibility that further discussion will result in a lawful verdict.
What Happens When Jurors Say They Are Deadlocked?
The first major step is usually continued deliberation.
Jurors may be asked whether they believe additional discussion could help. The judge can also remind them of their duty to consider the evidence fairly and listen to the views of their fellow jurors.
In some jurisdictions, a judge may issue an additional instruction encouraging jurors to make a genuine effort to reach a verdict. Such instructions are often associated with the term “Allen charge,” although the wording and procedures vary among courts.
The instruction cannot properly require jurors to abandon an honestly held position simply to produce a verdict.
A juror remains responsible for making an independent decision based on the evidence and law.
If additional deliberation succeeds, the jury can return a verdict.
If it does not, the judge can eventually conclude that the jury is deadlocked.
When Does a Hung Jury Become a Mistrial?
The terms describe two different parts of the process.
A hung jury describes the jury’s inability to reach the required verdict. A mistrial describes the court’s decision to end the trial without a final verdict on the unresolved matter.
For example, jurors may tell the judge that they are split and do not believe they can reach agreement. The judge may still send them back to deliberate.
If the disagreement continues, the court can determine that additional deliberation is unlikely to help. The judge can then discharge the jury and declare a mistrial.
The distinction is important because the first report of disagreement does not necessarily mean a mistrial has already occurred.
What Happens After a Mistrial?
Once a mistrial results from a genuine jury deadlock, several outcomes are possible.
The prosecution may decide to seek another trial. Prosecutors may also negotiate a plea agreement or decide not to proceed with some or all of the unresolved charges.
The defense can also evaluate its position after seeing how the first trial unfolded.
A mistrial therefore creates a new decision point rather than a guaranteed ending.
There is no rule requiring prosecutors to retry every case that ends with a deadlocked jury.
The strength of the evidence, seriousness of the charges, availability of witnesses and circumstances surrounding the first trial can all influence what happens next.
Can a Defendant Be Tried Again?
In many cases, yes.
A genuine jury deadlock generally does not prevent the government from conducting another trial. The U.S. Supreme Court has recognized that a mistrial caused by a genuinely deadlocked jury can permit a retrial without violating the constitutional protection against double jeopardy.
That principle is important because an acquittal and a deadlock are legally different.
An acquittal represents a final determination that the prosecution did not establish guilt. A deadlocked jury has not reached that determination.
Because there was no final verdict, prosecutors can generally seek another opportunity to present the unresolved case to a new jury.
The rules governing retrial can vary depending on the circumstances, particularly if the mistrial resulted from something other than a genuine jury deadlock.
Does Double Jeopardy Prevent a Second Trial?
Usually, not when the first trial ended because the jury genuinely could not agree.
Double jeopardy protections are a fundamental part of American criminal procedure. They generally prevent the government from repeatedly prosecuting someone after an acquittal or certain other final outcomes.
A hung jury is treated differently because the first jury failed to complete the decision-making process.
The legal system recognizes that a defendant should not automatically receive an acquittal merely because jurors could not reach the required agreement.
At the same time, prosecutors cannot simply declare any unfavorable situation a deadlock and assume a retrial will always be allowed. Courts examine whether the circumstances legally justified ending the first trial.
What If the Jury Acquits the Defendant?
An acquittal is very different from a deadlock.
If jurors return a valid not-guilty verdict, the prosecution generally cannot retry the defendant for the same offense. Double jeopardy protections are especially strong after an acquittal.
That means the prosecution cannot normally respond to an unfavorable verdict by simply selecting another jury and trying again.
The distinction between an acquittal and an unresolved case is therefore critical.
A hung jury means there was no final verdict. An acquittal means the jury reached a final decision in the defendant’s favor.
What If the Jury Convicts the Defendant?
A guilty verdict also ends the jury’s deliberation on the charges that received the conviction, although the case then moves into sentencing and potentially appellate proceedings.
A conviction is not the same as a deadlock.
If a jury finds the defendant guilty beyond the required standard, the judge can proceed according to the applicable law. The defendant may have the right to challenge the conviction through the appellate system.
A later legal reversal can raise separate questions about whether another trial is permitted.
Those circumstances differ from a simple jury deadlock because the first jury actually reached a verdict.
Can a Jury Reach a Partial Verdict?
Yes, depending on the charges and applicable court procedures.
A defendant may face multiple counts. Jurors can sometimes reach a verdict on certain counts while remaining unable to agree on others.
For instance, a jury could reach a not-guilty verdict on one charge while remaining deadlocked on another.
The resolved counts and unresolved counts are treated differently.
An acquittal on one count generally receives double jeopardy protection. A charge that remains unresolved because of a deadlock may potentially be retried.
The precise procedure depends on the jurisdiction and the court’s instructions.
How Long Can Jurors Deliberate?
There is no nationwide deadline.
Some juries reach a verdict after a few hours. Others spend several days reviewing complicated evidence.
The length of deliberation alone does not prove that a jury is deadlocked.
A jury could deliberate for many hours and eventually reach a unanimous verdict. Conversely, jurors can become convinced relatively quickly that they cannot reach agreement.
Judges consider the complexity of the trial, the amount of evidence, the number of charges and the jury’s communications with the court.
That is why courts generally avoid creating a rigid time limit for deliberations.
The Lindsay Clancy Trial Shows How the Process Works
The current Lindsay Clancy case provides a high-profile example of the issue.
Clancy is on trial in Plymouth, Massachusetts, over the deaths of her three children in January 2023. The central dispute has focused on her mental state and whether she should be held criminally responsible.
The trial included testimony from more than 80 witnesses and hundreds of exhibits. The jury began deliberating after weeks of evidence.
On September 1, 2026, jurors told Judge William Sullivan that they were unable to reach a unanimous decision.
The judge did not immediately declare a mistrial.
Instead, he directed the jurors to continue deliberating.
That distinction is significant. The jury had indicated that it was struggling to reach a decision, but the court had not yet ended the trial because of a formal deadlock.
The jury remained able to return a verdict if its members ultimately reached the required agreement.
Why the Judge Can Ask Jurors to Keep Deliberating
A jury’s first report of disagreement does not necessarily prove that no agreement is possible.
Jurors can reconsider arguments and evidence during further discussion. One member may raise a question that changes how another juror understands the case.
Additional deliberation can also help jurors separate factual disagreements from misunderstandings about the legal instructions.
The judge’s role is not to tell jurors which verdict to choose.
Instead, the court must protect the integrity of the deliberation process while determining whether the jury can still reach a lawful decision.
That is why judges may allow additional time before declaring a mistrial.
Can Prosecutors Force a Retrial?
Not automatically.
A prosecutor can seek another trial after a legally valid mistrial caused by jury deadlock, but the decision to proceed still involves practical and legal considerations.
The prosecution must evaluate the evidence again.
Attorneys may also consider whether witnesses remain available and whether another trial would be appropriate under the circumstances.
A defendant may also pursue negotiations after a mistrial.
The existence of a deadlock can change the balance between the two sides. Prosecutors know that the first jury did not reach a conviction, while defense attorneys know that the prosecution was unable to secure a final acquittal either.
That uncertainty can sometimes create an opening for a negotiated resolution.
What Happens to the Defendant During the Next Stage?
A mistrial does not automatically determine whether a defendant remains in custody or is released.
The court can consider applicable bail, detention and release conditions.
The defendant’s legal status depends on the charges, previous court orders and applicable law.
If prosecutors pursue a second trial, the defendant generally continues through the criminal process. A new jury would eventually hear the case if the matter proceeds to another trial.
The first jury’s inability to agree does not itself create a conviction or sentence.
Does a Second Trial Use the Same Jury?
Generally, no.
Once the court discharges a jury after a mistrial, a new trial ordinarily requires a new jury.
The second jury has its own responsibility to evaluate the evidence presented in court.
Jurors from the first trial generally do not return to decide the case again.
This means the outcome of a second trial can differ from the first.
A new group of jurors may view testimony, evidence and legal arguments differently.
Can the Outcome Change in a Retrial?
Absolutely.
A retrial does not guarantee the same result.
The prosecution could win a conviction, the defense could obtain an acquittal, or the jury could again fail to reach a verdict.
Attorneys may also change their strategies.
The first trial can reveal which evidence created disagreements or which issues were difficult for jurors to understand. Both sides can use that experience when preparing for another proceeding.
However, the second jury must make its decision based on the evidence and instructions presented during the retrial.
It does not simply adopt the position of the earlier jury.
Does a Hung Jury Mean the Defendant Is Innocent?
No.
A deadlocked jury does not establish innocence.
It also does not establish guilt.
The most accurate description is that the jury did not reach the required verdict.
This distinction can be particularly important in high-profile cases where public discussion quickly turns a jury disagreement into claims that one side has won.
Legally, the unresolved charges remain unresolved until they receive a final disposition.
The prosecution may have another opportunity if the law permits a retrial.
Does a Hung Jury Mean the Prosecutor Lost?
Not necessarily.
The prosecution did not obtain a conviction in the first trial, but a deadlock is not the same as an acquittal.
The government may still be able to retry the unresolved charges.
At the same time, a deadlock can reveal difficulties in the prosecution’s case. If jurors were divided over a central issue, prosecutors may need to decide whether another trial is worthwhile.
The defense faces a similar calculation.
Neither side automatically wins simply because jurors failed to agree.
What Are the Most Likely Next Steps?
Once a jury becomes genuinely deadlocked, the case can move in several directions:
- The judge can allow more deliberations.
- The jury can eventually reach a verdict.
- The judge can declare a mistrial.
- Prosecutors can seek a retrial.
- The parties can negotiate a plea.
- Prosecutors can dismiss unresolved charges.
- The court can address separate counts that already received verdicts.
Which path follows depends on the individual case.
There is no automatic rule that says every deadlocked jury must lead to a second trial.
Why the Distinction Matters in High-Profile Cases
High-profile trials often generate immediate public reactions when jurors report difficulty reaching a verdict.
However, a jury note saying that members cannot agree is only one stage of the process.
The court still has to determine whether additional deliberations could be productive.
That is particularly important in complex cases involving multiple charges, extensive evidence or difficult legal questions.
The Lindsay Clancy proceedings demonstrate this point. Even after jurors indicated that they could not reach unanimity, the judge instructed them to continue deliberating.
As of September 1, 2026, the case had not been resolved by a final verdict or a completed mistrial.
The Bottom Line
A deadlocked jury creates uncertainty, but it does not automatically end a criminal case. The judge can give jurors additional time to deliberate and may provide further instructions before deciding whether the impasse is permanent.
If a mistrial is ultimately declared because the jury cannot agree, prosecutors may be able to bring the unresolved charges before a new jury. Double jeopardy generally does not bar that type of retrial.
The most important distinction is between a deadlock and a final verdict. An acquittal normally ends the government’s ability to retry the same offense, while a genuine jury deadlock can leave the door open for another trial.
