Day 15 of Lindsay Clancy's murder trial ended abruptly Wednesday after a judge barred a former hospital employee from testifying and dismissed jurors over an unexplained disruption, leaving the defense one witness away from resting its case.
Judge William Sullivan sent the jury home from Plymouth Superior Court in Plymouth, Massachusetts, shortly after what was supposed to be an afternoon session, telling jurors only that "this is not something we saw coming" and warning them not to speculate about the cause. The early dismissal came after a morning that saw the defense's forensic psychologist finish his testimony and the judge reject a last-minute witness the defense had found through a TikTok video.
Clancy, a former Duxbury, Massachusetts, resident, has pleaded not guilty to first-degree murder in the January 24, 2023, killings of her three children, five-year-old Cora, three-year-old Dawson, and eight-month-old Callan. She admits she killed them. The question before the jury is whether she was criminally responsible at the time. If convicted, she faces life in prison without parole. If found not criminally responsible, she would be committed to a state psychiatric hospital.
Her defense team, led by attorney Kevin Reddington, argues Clancy was overmedicated and suffering from postpartum psychosis when she strangled the children with exercise bands in the family's basement. Prosecutors Jennifer Sprague and Shanan Buckingham counter that Clancy planned the killings, and that she faked a suicide attempt afterward that left her paralyzed and in a wheelchair.
Forensic psychologist Dr. Paul Zeizel, who began testifying Tuesday, wrapped up his time on the stand around 12:35 p.m. Wednesday. He had been the defense's most detailed witness on Clancy's mental state, and prosecutors used cross-examination to challenge both his conclusions and his closeness to the defendant.
Zeizel told the court he first met Clancy at the hospital in early February 2023, days after the killings. He described her current condition at Tewksbury State Hospital, where she remains under constant one-to-one suicide monitoring, in blunt terms.
CBS News Boston reported that Zeizel testified Clancy was "extremely well-regarded and well-liked" in her hospital unit, and offered his assessment of her daily reality:
"Lindsay Clancy has bad days and worse days. She does speak about her children. She really loved them, and misses them, and thinks of them every single day almost every moment of the day."
On the central legal question, Zeizel was direct. He testified that before the killings, Clancy believed her brain was damaged, that she would never recover, and that people could hear her thoughts, a delusion she feared would lead to her children being taken from her. After her discharge from McLean Hospital in Belmont, Massachusetts, in January 2023, the voices she was hearing "were getting worse and they were telling her to kill herself," Zeizel said.
His formal conclusion left no ambiguity about where the defense stands:
"My opinion is that she did have indeed a mental disease. She was unable to conform her behaviors to the rule of law, and she had no appreciation for the wrongfulness of her act."
Prosecutor Buckingham went after that conclusion methodically. She pointed out that when Clancy described intrusive thoughts to medical providers, "she never referred to them as a voice telling her to kill herself." Zeizel conceded the point, answering simply, "No."
Buckingham also pressed Zeizel on his relationship with Clancy. She asked how many defendants he had spent approximately 35 hours evaluating. "Only one other," Zeizel replied. She asked how many defendants he had "cared deeply for." His answer: "Only one." In high-profile criminal cases, that kind of emotional investment from an expert witness gives prosecutors an opening to argue the expert lost objectivity, and Buckingham took it.
She showed the jury video of Zeizel appearing alongside Reddington at a news conference, then asked pointedly: "How many defendants have you given press conferences about?" Zeizel maintained that caring for Clancy did not violate professional ethics and called it "appropriate and meaningful" to develop empathy and rapport with a patient. At one point, after an objection, the judge struck Zeizel's statement "I am telling the truth" from the record.
Buckingham also highlighted Clancy's own language about what happened. She noted that Clancy continually refers to the deaths of her children as "my tragedy", a phrasing that, in the prosecution's framing, suggests self-focus rather than the detachment from reality the defense claims. Zeizel called it "just one of the things that she'll say."
The broader trial record paints a picture of a woman whose mental health collapsed rapidly in the weeks before January 24, 2023. Clancy sought help for depression and psychotic symptoms of dissociation in late 2022. She called the suicide hotline twice in December and, according to Zeizel, did not receive help. She began treatment at McLean Hospital on New Year's Day 2023 and was discharged sometime later that month, 19 days before the killings, AP News reported.
Her ex-husband Patrick Clancy testified earlier in the trial that Lindsay developed severe insomnia after being prescribed Zoloft and was "extremely sleep deprived and highly anxious" at a December 2022 doctor's appointment. Defense attorney Reddington displayed six empty pill bottles recovered from Lindsay's nightstand during earlier testimony, all prescribed in December 2022 or January 2023, the New York Post reported.
Patrick Clancy has publicly defended his ex-wife, saying in a 2024 interview: "I wasn't married to a monster. I was married to someone who got sick." Prosecutors, however, believe Lindsay sent Patrick on an errand to get him out of the house before she killed the children. The 911 call he made after discovering them, in which he cried, "She killed the kids!", brought tears to the courtroom when it was played for the jury.
Lindsay's former mother-in-law, Susan Clancy, also testified for the defense, describing Lindsay as a "wonderful mother" who was "very nurturing, very loving" but who had been "begging for help" as her condition worsened. In a text message dated November 30, 2022, Lindsay told her mother-in-law: "I'm not okay and I'm terrified of taking meds tonight." By December, she had told family members she was having thoughts of harming the children and experiencing suicidal thoughts daily, Breitbart reported.
The case has drawn national attention in part because it sits at the intersection of criminal law and mental health policy, questions about whether the medical system failed a patient who was clearly deteriorating, and whether that failure should shield her from criminal responsibility for killing three children. Those are the kinds of questions that high-profile murder cases force courts to answer, and the answers have consequences far beyond one courtroom.
Before Zeizel finished, the judge held a separate hearing, without the jury present, on whether Emily Thorndike, a licensed clinical social worker and former McLean Hospital employee, should be allowed to testify. Thorndike had posted a widely viewed TikTok about her experience working at the facility from 2014 to 2021. Reddington saw the video and tried to contact her. When he could not reach her directly, he sent a private investigator to her home.
Thorndike told the judge during the hearing that she felt testimony presented at trial "was not aligned with what my experience was. I noted several things." She also felt some of the prosecution's questions about McLean Hospital were misleading, particularly regarding staffing levels around a holiday weekend, a detail relevant to the quality of care Clancy received during her stay.
Sullivan found Thorndike credible but ruled she could not testify before the jury, citing "limited materiality" and "limited value." He did, however, allow the defense to submit staffing records from McLean Hospital covering the week before and during Clancy's stay, giving jurors a way to compare staffing levels themselves. The distinction matters: the judge let the data in but kept the commentary out.
The ruling is a setback for the defense, which had hoped Thorndike could undercut the prosecution's characterization of McLean Hospital as a facility that provided adequate care. If the defense can show the hospital was understaffed or that Clancy's treatment fell short, it strengthens the argument that the medical system, not Clancy's own planning, bears responsibility for what happened next. Criminal trials often hinge on these kinds of evidentiary rulings, where a judge's gatekeeping decision shapes what the jury gets to hear. The role of forensic and documentary evidence in murder cases has been a recurring theme in major trials this year.
After the lunch break, the court was expected to resume around 2:15 p.m. Instead, Sullivan went to sidebar and then dismissed the jury for the day. He offered no explanation beyond telling jurors the disruption was "not something we saw coming" and instructing them not to hold it against either side.
Sullivan added that "the proceedings are still on schedule," and the trial is set to resume Thursday morning at 9 a.m. The defense expects to call one more witness before potentially resting its case. After that, the prosecution may call rebuttal witnesses.
The nature of the "unforeseen circumstance" remains unknown. It could involve a juror, a witness, a legal issue raised by one of the parties, or something else entirely. Sullivan's pointed instruction not to speculate suggests he considered it significant enough to warrant caution but not serious enough to derail the trial's timeline.
The Fox News coverage of Day 15 featured legal analyst Joshua Ritter noting that the defense's strategy has centered squarely on postpartum psychosis and the question of whether Clancy was dangerously overmedicated, a framing that asks the jury to see her not as a calculating killer but as a victim of a medical system that failed at every turn.
That framing carries real weight in a case where the defendant's own family members have testified on her behalf and her ex-husband has refused to call her a monster. But three children are dead. Cora was five. Dawson was three. Callan was eight months old. The prosecution's job is to make sure the jury never loses sight of that, no matter how sympathetic the defendant's mental health history may be. Criminal cases that generate intense public sympathy, or intense public anger, often become flashpoints for broader debates about accountability and justice.
Buckingham's cross-examination of Zeizel was designed to do exactly that: to show a defense expert who got too close, who cared too much, and whose conclusions may reflect emotional investment rather than clinical detachment. Whether the jury buys that argument, or whether they see a broken woman who never should have been discharged from a psychiatric hospital 19 days before she killed her children, is the question that will decide this case.
The trial resumes Thursday. And when the defense rests, the jury will face a choice that no amount of expert testimony can make simple: whether a mother who admits she killed her three children understood what she was doing when she did it. In a courtroom full of difficult legal questions, that one may be the hardest.
Three children cannot speak for themselves. Someone in that courtroom has to.
