One Week Before Trial: The Battle Lines in Commonwealth v. Lindsay Clancy

Seven days before a jury is called, a trial is often already half-decided in a nearly empty courtroom, in the arguments over what the jury will and will not be allowed to hear. That is what happened at the final pretrial hearing in Commonwealth of Massachusetts v. Lindsay Clancy. Over a single session, Judge William F. Sullivan of Plymouth County Superior Court worked through the motions that will govern one of the most closely watched trials in the country, and by the time the session ended the shape of the trial to come was no longer a mystery.

The Commonwealth was represented by Assistant District Attorney Jennifer Sprague, who has been the prosecution's leading courtroom voice since the earliest hearings, joined by Assistant District Attorney Shannon Buckingham. Lindsay Clancy was represented by Kevin Reddington, one of the most experienced criminal defense attorneys in Massachusetts. Clancy herself was present. She is presumed innocent of every charge against her, and nothing that follows changes that. A pretrial hearing decides what evidence a jury may consider. It decides nothing about guilt.

What made this hearing unusual is that the two sides do not disagree about the central events of January 24, 2023. They disagree about what those events mean, and about whether the law can hold Lindsay Clancy responsible for them. Almost every ruling in this session was a skirmish in that one larger war.

What Is Not in Dispute, and What Is

Early in the hearing, discussing a set of proposed stipulations that would spare the jury a long parade of laboratory witnesses, Reddington said the thing that defines this entire case. The mechanics of the deaths, he told the court, and the event itself, the defense is not contesting. He said it plainly, and he tied it to a practical point: the defense is willing to stipulate to so much of the forensic record precisely because it is not fighting over what physically happened. By the Commonwealth's own count, the stipulations under discussion could remove more than thirty largely ministerial witnesses from the trial.

It is essential to be precise about what that concession is, and what it is not. Conceding the mechanics of a death is not the same as pleading guilty. Under the law of the Commonwealth, a person can accept that her own acts caused a death and still stand not guilty, because guilt requires more than an act. It requires a mind the law will hold responsible for that act. That distinction is the hinge of the entire Clancy trial, and it is worth stating in the clearest possible terms: contesting criminal responsibility is not conceding guilt.

Massachusetts does not use the word "insanity" in its jury instructions. The governing standard comes from a case called Commonwealth v. McHoul. Under it, a defendant is not criminally responsible if, at the time of the offense, a mental disease or defect left her without substantial capacity either to appreciate the wrongfulness of her conduct or to conform her conduct to the requirements of the law. Read that carefully, because it is two separate doors, and the defense needs only one. It does not have to prove that Lindsay Clancy did not understand what she was doing. It can prevail by showing that illness destroyed her capacity to control what she was doing, even if some part of her understood it.

And there is a second rule that will sit at the center of this trial, one the hearing kept circling back to. Once a defendant fairly raises lack of criminal responsibility, the burden does not shift to her to prove she was ill. It stays with the Commonwealth, which must prove beyond a reasonable doubt that she was criminally responsible. In this trial the prosecution does not merely have to prove that Lindsay Clancy caused three deaths. It has to prove that her mind, on that night, belonged to her under the law.

The defense theory of that mind is specific. Reddington has said Clancy was suffering from postpartum depression and postpartum psychosis, and that she was involuntarily intoxicated by the numerous prescribed psychiatric medications she had been given in the months before. That combination, illness and medication, is the account the defense will ask the jury to weigh against the Commonwealth's account of a planned crime.

The Contested Statement of the Case

Before a jury hears a word of testimony, it is often read a short, neutral statement of the case so it understands what the dispute is about. In this trial, even that turned into a fight, because a statement of the case forces both sides to say, in a sentence or two, what they claim. Neither side was willing to let the other frame it.

The Commonwealth's proposed statement was blunt. It said that on the relevant date the defendant strangled her three children, named them and their ages, with exercise bands in the basement of the home, murdering them with deliberate premeditation and with extreme atrocity or cruelty. That is the prosecution's theory of first-degree murder distilled to its essence.

Reddington asked the court to add a paragraph of his own. In it, Lindsay Clancy would deny that she is guilty of murdering the children with deliberate premeditation and with extreme atrocity or cruelty, and it would state that she has accepted responsibility for the acts resulting in the deaths of her children, but was lacking criminal responsibility at the time as a result of postpartum depression, psychosis, and involuntary intoxication from the ingestion of numerous prescribed medications. The paragraph closed by saying she is not guilty by reason of a lack of criminal responsibility and will present what is commonly called the insanity defense. Read slowly, that paragraph is the whole defense in miniature: she did the acts; she was not, in law, responsible for them.

The Commonwealth objected to the paragraph as a whole. Prosecutors said they would not object to a spare version, that Lindsay Clancy denies the allegations and alleges she is not guilty by reason of a lack of criminal responsibility, but that the rest had to come in through witnesses and evidence, not be handed to the jury as an agreed fact before any evidence is heard. The prosecution's point cut in a direction worth noting: to say she denies murdering the children with premeditation and cruelty, the Commonwealth argued, sits awkwardly beside the defense's own position that what physically happened is not in dispute. And the assertion that she has "accepted responsibility," the prosecution said, would place a statement before the jury that might never actually be in evidence.

Judge Sullivan indicated he would likely give the jury a short framing of his own: that the question for them is whether Ms. Clancy was criminally responsible, that the Commonwealth carries the burden of proof, and that the prosecution must prove beyond a reasonable doubt that she was criminally responsible. That framing drew its own objection from the Commonwealth, and the objection is instructive. Prosecutors did not argue that the burden was anything other than theirs. They argued about timing, citing Commonwealth v. Santiago, that the Commonwealth is not required to prove criminal responsibility until the defense has actually raised it through evidence, and that instructing the jury on that burden at the very start, before any such evidence is in, risks improper burden-shifting. Reddington, for his part, asked the court to instruct the jury on the burden from the outset. Judge Sullivan said he generally gives the model instruction on the point and would show both sides his language before reading anything to the jury. The dispute was not over who bears the burden. It was over when the jury should be told.

Sixteen Trials Within a Trial

The most searching argument of the hearing came over a defense motion to allow other women to testify about their own experiences of postpartum mental illness. Reddington told the court he had been contacted by many people who described, in moving detail, living with postpartum depression and postpartum psychosis, including the experience of hearing command voices and enduring intrusive thoughts directed at those closest to them. His argument was that a juror's instinctive reaction to a claim of hearing voices is disbelief, and that women who have genuinely lived through it could testify credibly to a reality most jurors have never encountered.

Because the proposed witnesses had been identified only by initials, with no statements disclosed, the motion arrived at the hearing one week before trial with almost nothing attached to it. Reddington framed it as a threshold question: he asked the judge to act as a gatekeeper and decide, in principle, whether such lived-experience testimony could be admissible at all before he disclosed who these women were.

The Commonwealth opposed it on several grounds. Prosecutors argued it violated discovery rules given the timing and the absence of any information about the witnesses, that no rule of evidence permits a layperson to testify that she had an experience so that a jury may infer the defendant must have had it too, and that the battered-woman statute the defense pointed to itself contemplates expert testimony, not lay accounts. Above all, the prosecution argued the testimony would be more prejudicial than probative, because if the defense called a series of such women, the Commonwealth would be entitled to answer with its own: women who suffered postpartum depression and psychosis and did not harm their children, some of whom took deliberate steps to keep themselves from harm. Each side's witnesses would then need to be investigated and cross-examined, and the trial would fracture into a set of self-contained disputes about strangers.

Judge Sullivan captured the problem in a single phrase. This would not be a trial within a trial, he said. It would be sixteen trials within this trial. He denied the motion, reasoning that the reality of postpartum depression and psychosis is not genuinely in dispute between the parties, that experts on both sides are expected to testify to it, and that the properly probative content the defense wanted the jury to hear could come from those experts. He denied it, in his words, "this time," language that leaves a narrow door for the issue to return if the evidence at trial changes the calculus.

The Jury Will Go Home Every Night

Reddington asked the court to sequester the jury. His argument rested on the extraordinary nature of the case: a trial the Commonwealth estimates will run six to eight weeks, and pretrial publicity so heavy that the defense had already sought a change of venue, which was denied and which Reddington signaled he may renew depending on how prospective jurors respond during questioning. Even the possibility of sequestration, he argued, should be flagged for jurors so they could weigh it in judging their own availability.

The Commonwealth objected. Prosecutors argued that sequestration is rare in modern practice and unnecessary here, because the court will instruct jurors not to read about the case or discuss it on social media, will ask each morning whether they have followed those instructions, and is entitled to presume they will obey. Judge Sullivan agreed. He said he would ask jurors at the outset whether they had already heard anything that affected their impartiality, would instruct them daily to avoid coverage and social media, and would check in each day. On that footing, he denied the motion.

The ruling matters more than it may appear. For six to eight weeks, eighteen jurors will return each night to homes, phones, and feeds saturated with this case, held to their oath by nothing stronger than the judge's repeated instruction. Whether that instruction can hold against a case this prominent is one of the quiet tests the trial will run.

A Bus to Duxbury

The court took up the Commonwealth's motion for a jury view, a procedure in which jurors are physically taken to a location central to the case, here the Duxbury home. Judge Sullivan indicated he would allow the view and issue an order along the lines the Commonwealth proposed. The plan discussed at the hearing would bring the jurors, expected to number eighteen with alternates, to the home in small groups, with instructions not to open closets or handle personal belongings. The home is now occupied by a man and his partner and no longer resembles the residence as it was when the Clancy family lived there, a point Reddington noted for the record. The order governing the media would also bar any photographing of the jurors during the view.

Reddington raised one focused objection, and it was not to the view itself. It was to the manner of getting there. He asked the court to limit the police presence around the jury, describing prior cases in which officers on motorcycles rode alongside the jury bus and cruisers ran blue lights in front of and behind it. This case, he argued, involves no danger to jurors, and an overwhelming escort through a residential Duxbury neighborhood was unnecessary and risked coloring the jury's impression before they ever reached the house. The Commonwealth responded that a security plan was already in place. Judge Sullivan acknowledged the concern while noting that some measures, such as briefly closing a road, might be required for safety.

The Questionnaire, and the Stigma Problem

Prospective jurors in this trial will first complete a written questionnaire and review a witness list that, by the count given at the hearing, exceeds two hundred names. The questionnaire itself became a point of contention, and the fight over it was really a fight about how to screen a jury on the most sensitive subject the trial will touch.

The Commonwealth asked for two additions. First, that a question about family or personal history of postpartum depression, depression, or generalized anxiety disorder also include bipolar disorder, because, prosecutors said, the experts in the case have diagnosed the defendant with bipolar disorder and jurors' own experience with it would be relevant. Second, that the questionnaire ask about experience with or views about psychiatric medications, given how central medication is to both sides of this case.

Reddington resisted broadening the mental-health questions. His concern was the stigma that still attaches to psychiatric illness and treatment, and a practical consequence he described in detail: a juror who answers yes to having a history of mental-health treatment or medication invites follow-up questioning that can end in that juror being struck for cause. Pressing too many such questions, he argued, risks quietly excluding a large number of otherwise fair-minded citizens simply because they, or someone close to them, have received mental-health care, in a case where mental illness is the very heart of the defense. He urged the court to rely instead on a single, direct question already in the draft, which asks whether anything about the so-called insanity defense would prevent a juror from deciding the case fairly, and to let anything deeper surface during individual questioning at sidebar.

The Commonwealth answered that the questions get to the heart of the issues the case law says a court should explore in exactly this kind of trial, and asked that they be left as written. Judge Sullivan said he was inclined to keep the single direct question and perhaps one additional question in the same area, and to fold the deeper inquiry into the individual questioning he intends to conduct with each prospective juror at sidebar, where he will also cover a defendant's right not to testify and not to present evidence. He took the precise wording under review.

What Comes Next

By the close of the hearing, the trial had a shape. The Commonwealth estimates six to eight weeks. Judge Sullivan intends to seat eighteen jurors, and both sides had asked him to consider additional peremptory challenges given the length and emotional weight of the case, a request he took under advisement. Prospective jurors will complete the questionnaire, review the two-hundred-name witness list, and then be questioned one at a time at sidebar before a panel is seated. A jury view of the Duxbury home is set to go forward. Expert psychiatric testimony, which both sides agree is coming, will carry the weight of the case.

Underneath all of it sits the single question the hearing kept returning to. Not what happened in that home, which the defense will not contest, but whether the woman who was there can be held responsible for it under the law, and whether the Commonwealth can prove beyond a reasonable doubt that she can. Everything decided at this hearing, the statement the jury will hear, the witnesses it will not, the questions it will answer, the house it will walk through, was one more move in that contest.

Lindsay Clancy is presumed innocent. The Commonwealth's allegations are allegations. What separates a verdict from a verdict-shaped opinion is the process, and the process is what we came to watch.
