STUNNING DEVELOPMENT — JUDGE DROPS BOMBSHELL IN LINDSAY CLANCY CASE
Clancy Defense Seeks Inquiry Into Lone Holdout Juror—But No Juror Misconduct Has Been Found and a Retrial Remains Possible
The Lindsay Clancy case has entered a new phase after her murder trial ended without a verdict.
Defense attorney Kevin Reddington is asking Plymouth Superior Court Judge William Sullivan to conduct a limited inquiry into Michael Péguy Desronvil, the lone juror who favored conviction while the other 11 jurors were prepared to find Clancy not guilty by reason of lack of criminal responsibility.
The request is significant.
But it is not yet a judicial finding that Desronvil committed misconduct.
It is a defense motion asking the court to investigate several unresolved questions: whether he was truthful during jury selection, whether his prior legal history should have been disclosed or discovered, and whether he improperly used a cellphone during deliberations.
Judge Sullivan has preserved or impounded relevant jury materials but has not yet granted the broader investigation requested by the defense.
That distinction matters because some accounts are describing the filing as a “judge bombshell.”
The judge has not ruled that Desronvil was unqualified.
He has not found that the juror lied.
He has not found that outside information affected the deliberations.
And he has not dismissed the charges against Clancy.
The next major court date is September 29.
The background to the motion is the mistrial declared on September 4, 2026.
Clancy, 36, is charged with three counts of first-degree murder in the January 24, 2023 deaths of her children Cora, 5, Dawson, 3, and Callan, 8 months, at the family’s home in Duxbury, Massachusetts.
Clancy does not dispute that she killed the children.
Her defense has argued that she was suffering from severe postpartum psychiatric illness, including postpartum psychosis, and lacked criminal responsibility at the time.
Prosecutors have argued that she understood what she was doing and knew it was wrong.
After a lengthy trial and seven days of deliberations, the jury could not reach a unanimous verdict.
Jurors who later spoke publicly described an 11-1 split.
Eleven were prepared to find Clancy not criminally responsible.
Desronvil disagreed and favored conviction.
Massachusetts requires unanimity for a criminal verdict.
Judge Sullivan ultimately declared a mistrial after the jury repeatedly reported that it was deadlocked.
The defense’s new motion does not challenge Desronvil merely because he voted differently from the other jurors.
A holdout juror is allowed to disagree.
The constitutional jury system does not require a minority juror to surrender an honestly held view simply because the rest of the panel disagrees.
The defense is instead trying to determine whether something separate from Desronvil’s vote affected his qualification or conduct.
One issue is his juror questionnaire and answers during jury selection.
Reddington has asked the court to preserve the confidential questionnaires completed by the 12 jurors and six alternates.
He also wants to know what background checks were performed before Desronvil was seated.
The request follows reporting that Desronvil had previously been charged in a domestic-violence case and was subject to a civil restraining order during part of the Clancy trial.
NBC10 Boston reported that in 2021, Desronvil’s then-13-year-old nephew called 911 and alleged that Desronvil grabbed his wife by the throat and threw her into a dresser.
Desronvil was charged with assault and battery on a family or household member.
That criminal charge was later dismissed.
A dismissed charge is not a conviction.
It cannot responsibly be described as proof that the alleged conduct occurred.
A separate civil dispute involving the nephew is also part of the defense’s inquiry.
Court records reported by NBC10 Boston and The Boston Globe show that a restraining order was issued against Desronvil in 2025 after the nephew alleged another confrontation.
The order required Desronvil to stay away from the nephew and remained active through August 11, 2026, during the Clancy trial.
The allegations underlying that order have not been established as criminal convictions.
The existence of the order is nevertheless relevant to the defense’s current question: whether Desronvil was required to disclose that history during jury selection and, if so, whether his answers were accurate.
That question cannot be resolved merely by finding the court records.
The court would have to compare the actual juror questionnaire, the questions asked during voir dire, Desronvil’s answers and any instructions about what prospective jurors were required to disclose.
Reddington has therefore asked Sullivan to preserve and examine those materials rather than simply assume misconduct occurred.
The defense has also asked whether Desronvil had been involved, as either a defendant or complainant, in matters handled by the Plymouth County District Attorney’s Office since 2021.
The theory appears to be that prior interactions with the prosecuting office could have been relevant to bias or disclosure.
Again, the existence of prior contact would not automatically prove bias.
The court would have to determine whether the contact existed, whether it was material and whether the juror answered relevant selection questions truthfully.
The second major issue is cellphone use.
Fellow juror Nick Dargie told ABC News that Desronvil sometimes appeared disengaged from the discussion and scrolled on his phone while other jurors were speaking to him.
“There was times he wouldn’t engage, like he’d be scrolling on his phone while people are talking to him,” Dargie said.
That allegation is important because Massachusetts court policy restricts jurors’ use of electronic devices.
The Massachusetts Trial Court instructs jurors not to use cellphones, computers or other communication devices while attending trial or during jury deliberations.
The policy is intended both to protect the deliberative process and to prevent jurors from receiving or seeking outside information about a case.
Massachusetts jury instructions specifically warn that cellphones during deliberations can disrupt deliberations or allow improper extraneous information into the jury room.
Reddington therefore wants more than witness recollections.
His motion seeks records showing calls, text messages and data activity on Desronvil’s phone between 8 a.m. and 4:30 p.m. on each day of deliberations.
He has also asked that the phone itself be preserved and examined by a neutral forensic expert.
The defense wants mobile-device sign-in sheets, court-officer records and video from the corridor outside the jury room as well.
Those requests are aimed at establishing objective facts.
Was the phone present?
Was it being used?
Was it connected to the internet?
Was any outside information received?
Those questions are different from asking what Desronvil thought about the evidence.
The secrecy of jury deliberations remains an important legal boundary.
Courts are generally reluctant to conduct broad post-verdict or post-mistrial investigations into a juror’s reasoning because jurors must be able to deliberate without fear that their votes will later subject them to interrogation.
That protection is especially important for a lone holdout.
If every dissenting juror could be investigated simply because the majority disliked the result, independent deliberation would be weakened.
Reddington’s motion therefore describes the requested process as a limited inquiry.
The stated focus is alleged external conduct: phone use, possible outside information and the accuracy of jury-selection answers.
The defense says it is not seeking disclosure of the substance of confidential jury discussions.
Desronvil’s attorney, Edward Paltzik, strongly disputes the defense’s effort.
He has described the motion as dangerous and an attack on the independence of jurors.
His position is that Desronvil acted as a conscientious juror and should not face a retrospective investigation simply for refusing to join the majority.
Desronvil has also rejected the suggestion that he was uncertain about Clancy’s criminal responsibility.
“I didn’t have any doubts,” he said in a statement released through his lawyer.
He said the prosecution’s physical evidence and witnesses convinced him that Clancy knew what she was doing and planned her actions.
That statement conflicts with accounts from some of the other jurors.
They have said Desronvil expressed reasonable doubt during deliberations or failed to meaningfully engage with arguments supporting a lack-of-criminal-responsibility verdict.
Those competing recollections are part of why the post-trial dispute has become so intense.
But disagreement about what one juror meant during deliberations does not itself establish misconduct.
The central legal questions concern whether he violated court rules or concealed material information.
Another defense filing raises an even larger issue: whether Clancy can be retried at all.
Her lawyers have asked the court to dismiss the case on double-jeopardy grounds.
They argue that Judge Sullivan should not have declared a mistrial without first resolving concerns surrounding the holdout juror, potentially including whether an alternate could have been substituted if there were legally sufficient grounds to remove Desronvil.
The defense says the mistrial lacked the “manifest necessity” required to permit another prosecution after jeopardy had attached.
That argument is contested.
The ordinary rule is that a hung jury can constitute manifest necessity for a mistrial, allowing prosecutors to retry the defendant.
The defense is arguing that this particular mistrial was different because questions about the holdout juror should have been addressed before the jury was discharged.
Judge Sullivan has not accepted that argument.
No court has ruled that a second trial would violate double jeopardy.
Former Suffolk County District Attorney Daniel Conley told The Boston Globe that the juror investigation is unusual and that even proof of phone use or incomplete disclosure would not necessarily lead to dismissal of the charges.
That is an important caution.
Juror misconduct can have serious consequences.
But the remedy depends on what happened, when it happened, whether it affected the proceedings and what legal options were available to the trial judge.
There is no automatic rule that alleged juror misconduct after a mistrial converts into an acquittal.
The prosecutor’s next move is also unresolved.
Plymouth County District Attorney Timothy Cruz has not publicly announced whether the Commonwealth will retry Clancy.
A mistrial ordinarily leaves the charges pending.
Clancy therefore remains charged with murder.
She has not been acquitted.
She has not been convicted.
And the 11-1 split reported by jurors is not itself a verdict.
That is another distinction worth preserving.
Eleven jurors may have favored a lack-of-criminal-responsibility finding, but Massachusetts criminal verdicts must be unanimous.
Their position does not become a legal acquittal simply because it represented the overwhelming majority of the panel.
Likewise, Desronvil’s vote for conviction did not establish guilt.
The jury reached no verdict at all.
The case remains unresolved.
The September 29 hearing could therefore become important for several different reasons.
The judge may address the defense request for a limited juror inquiry.
The court may consider arguments related to dismissal or double jeopardy.
Prosecutors may provide more information about whether they intend to seek a retrial.
And the court may establish how the case proceeds if the charges remain active.
What the hearing will not do automatically is validate every allegation now being made about Desronvil.
His dismissed domestic-violence charge remains a dismissed charge.
The civil restraining order is a real court record, but the underlying allegations are not criminal convictions.
The cellphone allegation comes from another juror and has not yet been established through phone records or forensic examination.
The defense’s questions about Desronvil’s jury questionnaire are exactly that: questions that require comparison with the confidential form and voir-dire record.
The judge’s preservation orders do not amount to findings of wrongdoing.
Preserving records protects evidence so that the court can decide later whether further inquiry is appropriate.
That procedural step is significant, but it should not be confused with a ruling on the merits.
The broader public dispute surrounding Desronvil also deserves caution.
He has faced substantial online criticism since his identity became public.
His attorney says he has received threats and has moved to an undisclosed location.
A fundraiser established in his name has also attracted significant attention.
Whatever people think of his vote, jurors are entitled to personal safety.
The legitimacy of an investigation must therefore turn on evidence of possible misconduct, not public anger over the outcome.
The same restraint applies to Clancy.
The facts of the case are extraordinarily painful.
Three children died.
Their mother admits causing their deaths.
The central dispute at trial was whether, because of her mental condition, Massachusetts law holds her criminally responsible for those acts.
The defense presented postpartum psychosis and other psychiatric evidence.
The prosecution presented evidence that it says showed planning, awareness and knowledge of wrongfulness.
The first jury did not resolve that conflict.
The new juror motion does not resolve it either.
It concerns the integrity of the process that produced the deadlock.
That makes the development genuinely important without requiring a sensational headline.
The defense has identified specific issues capable of objective investigation.
There was a prior dismissed criminal charge.
There was an active civil restraining order during part of the trial.
There are allegations of phone use during deliberations.
There are questions about what was disclosed during jury selection.
And Massachusetts rules do prohibit jurors from using cellphones during deliberations.
Those facts justify scrutiny.
But the next steps belong to Judge Sullivan.
As of now, he has not found that Michael Desronvil lied during jury selection.
He has not found that Desronvil violated the phone rule.
He has not found that the juror obtained outside information.
He has not ruled that the mistrial was improper.
And he has not barred prosecutors from trying Lindsay Clancy again.
The strongest accurate headline is therefore narrower than a “judge bombshell.”
The Clancy defense is seeking a judicial inquiry into the lone holdout juror after an 11-1 mistrial.
The motion raises serious questions about juror disclosure and cellphone use.

They have not yet been answered.
