Facts

Cora was five. Dawson was three. Callan was eight months old. On January 24, 2023, their mother, Lindsay Clancy, strangled them with exercise bands in the basement of the family’s Duxbury home while her husband was out getting takeout and a drugstore order. She then took medication, cut her wrists and neck, and went out a second-story window. Cora and Dawson were dead when Patrick Clancy found them. Callan survived the initial strangulation but died days later. Lindsay Clancy lived. She is paralyzed from the waist down. She is still charged with three counts of first-degree murder.

Process

A Plymouth County jury sat through five weeks of testimony and then spent nearly forty hours failing to reach a verdict on whether she was criminally responsible. By the defense’s own account, the split was 11-1 toward a finding of no criminal responsibility. Judge William Sullivan declared a mistrial on September 4. District Attorney Timothy Cruz has not yet said whether he will try the case again.

He should. And he should not try the same case the same way.

The first trial let the defense turn a triple filicide into an extended seminar on postpartum mental health. That is not an accident of a hard case, it is a strategic opening the defense was handed and used well. Massachusetts law already gives the defense a significant advantage: once lack of criminal responsibility is raised, the Commonwealth must disprove it beyond a reasonable doubt. Defense attorney Kevin Reddington used that rule, a sympathetic client in a wheelchair, and weeks of clinical testimony to build a story about a system failing a mother. Eleven jurors found enough of it credible to hang the panel. If the case is retried on the same footing, why should twelve jurors land anywhere different?

The missing motive

Motive is not an element of murder in Massachusetts. But it is the thing a deadlocked jury reaches for when competing experts talk past each other for weeks. The first prosecution told jurors Clancy planned the afternoon, sent her husband out of the house, and understood right from wrong. That’s necessary groundwork. Is it enough? “She planned it” tells a jury the clock. It does not tell them why a labor-and-delivery nurse who had spent years presenting as a devoted mother would methodically kill the three people her identity as a mother was built around.

Here is a question the next prosecutor should put in front of the jury and force the defense to answer, rather than a theory asserted as settled fact: could the reorganization of who gets attention inside that household? Was this all about Lindsay’s search for attention when the children began to draw it away from her? As Lindsay’s medical demands grew, a nanny hired three days a week, both sets of grandparents brought in, a husband restructuring his work life to be home.  How could this have mattered to how this case unfolded? The former nanny, Elaine Rossi, testified she saw a devoted mother and never had concerns Clancy would harm her children. That testimony supports one story. Does it foreclose the question of what it meant, to Clancy specifically, when the help she’d asked for started giving all attention to the children that had previously been trained on her? Was the arrival of extensive outside support something she experienced as relief, or as displacement? No expert in the first trial was asked that question directly. The next prosecutor should ask it.

If a jury is going to be told this was postpartum psychosis and nothing else, they deserve to hear an expert tested on the alternative: is there a personality pattern in which a person needs to remain the center of crisis and family concern, and if that need collides with a sustained shift of attention onto children, what does the psychiatric literature say that collision can produce? That is a legitimate, answerable clinical question. It is not this piece’s place to diagnose a specific, named defendant with it. It is the next trial’s place to ask its experts whether the facts support it, and to make the defense’s experts answer the same question under cross-examination.

The “suicide” that knew too much

The defense needs the window, the cuts, and the pills to establish that Clancy was trying, without reservation, to die, because an incomplete, ambivalent attempt cuts against the picture of someone so disorganized by psychosis that she couldn’t appreciate what she’d done. The trial record contains a fact worth sitting with: an investigator testified that a forensic report showed searches from Clancy’s phone for “where is the carotid artery” and “how to slit your throat to die,” though the officer could not personally confirm the searches were run before the killings, only that the device identifier matched hers. Separately, first responders and treating clinicians testified that the cuts to her neck and wrists were “superficial” and not actively bleeding when help arrived, while one wrist wound was deep enough to require sutures.

As a trained nurse, did Clancy know, in the abstract, where the major vessels in the neck and wrist are and what it takes to open them? That is a fair question for the jury, not an assumption the prosecution gets to skip past. If she had that knowledge, why do the wounds that were actually inflicted not match it? The defense’s answer is that psychosis explains the mismatch, a mind so overtaken it couldn’t execute what it may have once understood. Is that the only explanation consistent with the evidence, or could a jury reasonably ask whether someone capable of assembling three distinct methods in sequence, medication, cutting, a fall from height, was engaged in something more deliberate and more visible than a single, resolved attempt to die? The prosecution raised a version of this question in the first trial. It should not merely raise it again. It should make its own forensic psychiatrist answer it head-on, and cross-examine the defense’s expert on what a genuinely incapacitating psychotic episode does and doesn’t look like in real time, method by method. The prosecutor should also question how a person who has just systematically murdered three children with no indication of hesitation could then engage in a complicated suicide attempt that had hesitation at every point. Is it reasonable to question whether or not the suicide attempt was manufactured as a exculpatory mechanism?

What the first trial got wrong

Cruz’s office charged first-degree murder and then spent weeks re-establishing mechanics that were never in dispute. That is how a prosecution loses control of the story. Reddington wanted the case to be about medicine, hospitals, and whether the system fails mothers. Prosecutors who don’t offer the jury a competing frame for why, not just that and how, are fighting on the defense’s chosen ground.

The Commonwealth also has to reckon honestly with its burden. It does not merely need to suggest Clancy was sane. It must prove, beyond a reasonable doubt, that at the moment of the killings she retained substantial capacity to appreciate the wrongfulness of her acts and to conform her conduct to the law. A jury that spends a month steeped in postpartum psychiatric testimony will not carry that burden out of instinct or sympathy. They need a competing narrative, built on the record, that makes the planning evidence look like a planning mind still working, not a mind that had broken.

What the next prosecutor should do

First, retry the case. A hung jury is not an acquittal. Declining to go again tells every future defendant in a high-sympathy filicide case that one holdout juror plus a strong medical narrative is enough.

Second, don’t let the defense own the diagnosis. Retain experts prepared to address personality and motive, not only mood and psychosis, and put the question to them directly: is the pattern here, the planning, the sequenced and non-lethal suicide attempt, the documented searches, the testimony about her need for attention and help, better explained by incapacitating psychosis alone, or does it raise a live question the jury should be allowed to weigh? Let the defense argue psychosis is the only explanation. Make them defend that position against a real alternative, instead of letting it stand unchallenged because no one offered a competing theory.

Third, try the case on the hour-by-hour record.  She mapped out the afternoon. She sent her husband for takeout and a pharmacy run. She chose the basement. Days later, a psychiatrist who evaluated her found her calm and organized enough to consent to her own surgery required after her fall. Ask the jury directly: is that consistent with someone who lacked, hours earlier, the substantial capacity the insanity standard requires?

Fourth, put her clinical training in front of the jury as evidence, not commentary. What does a nurse’s professional knowledge of lethality and anatomy suggest about suicide intent, and does the actual outcome of her attempt match or contradict that knowledge? Let the jury decide, don’t hand them the conclusion.

Fifth, keep the children visible. Cruz said after the mistrial that it’s the office’s job to make sure the victims aren’t invisible. In the first trial, they too often were. The 911 call, the ages, the medical examiner’s findings, these aren’t spectacle. They’re the corrective to any narrative that frames three deaths primarily as something that happened to their mother.

Sixth, don’t pre-concede the frame because of one number.  An 11-1 split is a warning about presentation and strategy. It is not a finding of fact, and it shouldn’t be treated as a ceiling on what the next trial can achieve.

The point, which is also the legal point

A serious society can hold two things at once: postpartum psychiatric illness is real, and women in genuine crisis are too often failed by fragmented care and none of that answers whether a specific defendant, on a specific night, retained the legal capacity the insanity standard requires. The first trial let those two questions blur into one. The retrial’s job is to keep them separate, and to make sure that whatever sympathy this case understandably generates for a woman who has suffered doesn’t quietly stand in the way for the finding a jury is legally required to make.

Cora, Dawson, and Callan don’t get a retrial. They are dead. But their mother does. The next prosecutor’s obligation is to make sure that trial actually resolves the question the law asks, not the question the last trial let go unanswered.
