Jurors in Plymouth Superior Court returned Friday morning to continue weighing whether Lindsay Clancy can be held criminally responsible for the deaths of her three young children at the family's Duxbury home in January 2023. They began deliberating Thursday afternoon without reaching a decision. No verdict had been returned as of the most recent court update.
For readers, the case has become the most visible public conversation about postpartum psychosis in years, and clinicians who treat the condition say that visibility carries a risk. If the only message the public absorbs is that postpartum psychosis produces violence, the mothers who most need care are the ones least likely to ask for it.
That tension is the reason this trial matters beyond the courtroom. About 3.6 million people give birth in the United States each year, and a small number of them will develop a psychiatric emergency in the weeks afterward that neither they nor their families will recognize.
Five Options on Three Separate Verdict Slips
Judge William F. Sullivan gave jurors three verdict slips, one for each child, and each slip carries the same five choices, as described from the courtroom: not guilty, not guilty by reason of lack of criminal responsibility, guilty of first degree murder, guilty of second degree murder, and guilty of manslaughter. Massachusetts requires a unanimous decision.
Clancy, 36, has pleaded not guilty to three counts of first-degree murder. Her attorney, Kevin Reddington, argued she was experiencing severe postpartum psychosis and was taking multiple psychiatric medications at the time, and told jurors she had repeatedly sought help and was overmedicated and misdiagnosed. Prosecutors argued in remarks reported from the courtroom that the former labor and delivery nurse acted deliberately, sending her husband out on errands before the killings.
Massachusetts law places the burden on prosecutors to prove criminal responsibility beyond a reasonable doubt, a narrower, more defense-favorable standard than many states use. A first-degree conviction carries a mandatory sentence of life without parole. If jurors find her not criminally responsible, prosecutors can petition to commit her to a psychiatric facility rather than release her.
The Legal Question Is Narrower Than the Public Debate
Much of the online argument about this case treats the verdict as a referendum on whether postpartum psychosis is real. It is not. The condition is well described in psychiatry, and the jury is not being asked to rule on its existence.
The question in front of jurors is whether, at the moment of the killings, Clancy could appreciate that what she was doing was wrong or conform her conduct to the law. Experts on both sides examined her and reached different conclusions. The defense's final witness, forensic psychiatrist Phillip Resnick, testified that she was psychotic that day. Two prosecution rebuttal witnesses disagreed. Forensic psychologist Kirk Heilbrun testified for prosecutors that Clancy had serious mental illness, which he assessed as bipolar 2 disorder, but that she understood the wrongfulness of her actions and could conform them to the law. He also said a voice reported only during the killings would be a very unusual pattern.
That kind of disagreement is ordinary in forensic psychiatry and does not indicate that either side is fabricating. Retrospective assessment of someone's mental state years after an event is difficult, and reasonable specialists reviewing the same records regularly land in different places.
Clinicians Call This Condition a Psychiatric Emergency
Postpartum psychosis is rare, fast-moving, and treatable, and the treatable part gets lost in trial coverage. Susan Hatters Friedman, MD, the Phillip J. Resnick Professor of Forensic Psychiatry at Case Western Reserve University, told Psychiatric Times that it "typically presents fulminantly" in the weeks after delivery, with symptoms that come and go.
That waxing-and-waning pattern is a diagnostic trap. A mother can look coherent at an appointment and be severely unwell hours later, which is why Hatters Friedman advises clinicians to gather information from family rather than relying on a single conversation. She also notes that the condition involves confusion and dysphoric mania alongside psychotic symptoms, not psychosis alone, and that a medical complication of delivery can present similarly and require entirely different treatment.
Risk is not evenly distributed. A personal history of bipolar disorder raises the risk strongly, by up to a hundredfold compared with the general population, and a prior episode of postpartum psychosis or a family history of it are also major risk factors. Treatment usually begins with inpatient admission, and lithium, second-generation antipsychotics, and electroconvulsive therapy are among the established options.
Coverage That Emphasizes Risk Can Keep Mothers From Care
The clinical warning attached to this trial is about what happens after the verdict. Hatters Friedman said that if the public message is only about risk, the worry is that symptomatic women will avoid treatment out of stigma and fear of losing custody of their children.
That is the practical takeaway for households. New parents and their partners should know that agitation, confusion, not sleeping even when the baby sleeps, rapid mood shifts, or beliefs and perceptions that others do not share are reasons to seek help the same day rather than wait for a scheduled visit. This is treated as an emergency, and emergency departments and crisis lines are appropriate points of entry.
There is also a structural gap worth naming. Postpartum psychosis does not appear in the diagnostic manual clinicians and courts rely on, which Hatters Friedman argues limits training, research, and recognition. She notes that many parents attend pediatric visits far more reliably than their own postpartum checkups, which makes pediatric offices an underused place to catch maternal illness early.

Key Questions Answered
Has a verdict been reached? No. Jurors began deliberating Thursday afternoon and returned Friday morning to continue. Massachusetts requires a unanimous decision on each of three verdict slips.
What are jurors actually deciding? Whether prosecutors proved beyond a reasonable doubt that Clancy was criminally responsible, meaning she could appreciate that her conduct was wrong or conform it to the law.
What happens if she is found not criminally responsible? She would not be released outright. Prosecutors can petition for commitment to a psychiatric facility, which a judge can order.
How common is postpartum psychosis? It is rare, far less common than postpartum depression or postpartum anxiety, and less common than the intrusive thoughts seen in postpartum obsessive-compulsive disorder.
Who is at highest risk? People with a personal history of bipolar disorder face substantially elevated risk. A previous episode of postpartum psychosis or a family history of it are also major risk factors.
What symptoms should a partner or family member watch for? Confusion, agitation, an inability to sleep even when the baby is sleeping, rapidly shifting mood, and beliefs or perceptions others do not share. These warrant same-day help.
Where can someone get help right now? Call or text 988 for the Suicide and Crisis Lifeline, or go to an emergency department. Postpartum psychosis is treated as a psychiatric emergency and usually requires hospital admission.
