Lindsay Clancy Trial Testimony Ends with Bombshell Admission from Psych Expert
PLYMOUTH, Mᴀss. — After more than five weeks of wrenching testimony, the high-profile murder trial of Lindsay Clancy drew to a close on Wednesday with a striking concession from the prosecution’s final expert witness. Forensic psychiatrist Dr. Gregory Saathoff, called by the Plymouth County District Attorney’s Office, acknowledged under cross-examination that the state’s own opening statement “really minimizes” the profound mental health struggles the 36-year-old former labor and delivery nurse endured in the months before she killed her three young children.
The admission came as defense attorney Kevin Reddington pressed Saathoff on the prosecution’s portrayal of Clancy as a calculating woman who simply grew tired of her life and chose a selfish escape. Reading at length from prosecutor Shanan Buckingham’s July 27 opening remarks, Reddington highlighted language claiming Clancy “manipulated” her healthcare providers, sought “a quick and easy fix,” and, after only four months of treatment, made a “deliberate and intentional decision” that she no longer wanted to try. When the medications and care plans failed to meet her expectations, the prosecutor had argued, Clancy chose an alternate route — killing her children so no one else would have to care for them, then attempting to take her own life.
“Would you agree that the evidence in your opinion supports that contention, sir?” Reddington asked.
After some hesitation, Saathoff replied: “I think that statement that you read really minimizes what [Clancy] was going through.”
With that, Reddington ended his cross-examination. The Commonwealth rested. Closing arguments are scheduled for Thursday, after which the jury of 18 — including alternates — will begin deliberating whether Clancy is criminally responsible for the deaths of Cora, 5; Dawson, 3; and Callan, 8 months.
The case has drawn national and international attention for its focus on postpartum psychosis, a rare and severe mental illness that affects roughly one to two women per 1,000 births. Clancy does not dispute that she strangled her children with exercise resistance bands in the basement of the family’s home in coastal Duxbury on the evening of January 24, 2023. Her defense centers on a claim of lack of criminal responsibility: that she was in the grip of severe postpartum psychosis and bipolar disorder, unable to appreciate the wrongfulness of her actions or conform her conduct to the law. She has pleaded not guilty to three counts of first-degree murder.
Prosecutors paint a starkly different picture. They contend Clancy acted intentionally, rationally, and with premeditation. They argue she sent her then-husband, Patrick Clancy, on errands — to pick up takeout dinner and medication for Cora’s stomachache — precisely so she could carry out the killings alone. Saathoff and other state experts have testified that her behavior that day was “methodical, quite controlled and organized.” They point to inconsistencies in her accounts of when and how a male voice allegedly commanded her to kill the children and herself, and note that she reported hearing the voice only during the act itself — never before and never after.
A Mother’s Descent
Lindsay Clancy had worked as a labor and delivery nurse at Mᴀssachusetts General Hospital. After the birth of her third child, Callan, in May 2022, her mental health deteriorated rapidly. By September she was seeking help for crippling insomnia, anxiety, depression, and intrusive thoughts. She saw multiple providers, called a suicide H๏τline twice, checked herself into a psychiatric hospital for five days in early January 2023, and sought care at perinatal clinics. Medical records documented repeated suicidal ideation and, on at least two occasions, thoughts of harming the children that she shared with her mother and husband.
Over roughly four months she received some 30 prescriptions for 13 different psychiatric medications. Testimony and lawsuits filed by both Lindsay and Patrick Clancy have described a chaotic period of medication changes, side effects, and frustration when treatments failed to bring lasting relief. Phone data presented at trial showed searches related to hallucinations, psychosis, schizophrenia, bipolar disorder, suicide methods, and drug side effects in the weeks before the killings.
On the morning of January 24, Clancy took Cora to a pediatrician appointment and later played in the snow with the children, building a snowman and doing art projects. Patrick later testified that she seemed to be having “one of her best days.” That afternoon she ordered takeout. Around 5:15 p.m. she asked Patrick to retrieve the food and stop for medicine. While he was gone — a window of less than an hour — she took the children one by one to the basement and strangled them with exercise bands. She then cut her wrists and neck, swallowed pills from multiple prescriptions, and jumped from a second-story bedroom window. She survived but sustained spinal injuries that left her paraplegic and wheelchair-bound. Callan lingered on life support for three days before dying.
Patrick returned home to a locked bedroom, blood, an open window, and his wife on the ground outside. Inside he found the children. His frantic 911 call was played for the jury. The couple has since divorced.
Competing Psychiatric Narratives
The trial featured roughly 85 witnesses, including about 10 for the defense. Family members, friends, treating clinicians, and forensic experts described Clancy’s months-long struggle. Defense experts, including renowned forensic psychiatrist Dr. Phillip Resnick, diagnosed postpartum psychosis and bipolar disorder. They testified that Clancy experienced command hallucinations and a delusion of influence that left her unable to resist the voice’s instructions. Psychologist Paul Zeizel, who met Clancy in the hospital shortly after the killings and later evaluated her extensively, told jurors she could neither appreciate the wrongfulness of her acts nor conform her behavior to the law.
Saathoff, a University of Virginia forensic psychiatrist who has consulted for the FBI’s Behavioral Analysis Unit, offered the opposite conclusion. He interviewed Clancy for a total of about 11 hours via video in 2026, reviewed voluminous records, and spoke with Patrick Clancy. He accepted that she suffered from a mental disease or defect — bipolar disorder — but maintained she retained the capacity to know right from wrong and control her actions. He found her account of the voice unconvincing: it appeared only on the day of the killings, was constant rather than intermittent, gave no specific instructions on method or sequence, and stopped once the children were ᴅᴇᴀᴅ. “Committing the act is not curative of the voice,” he said. “I’ve not ever seen that.” He also noted that Clancy called Patrick back while he was at the pharmacy, locked the bedroom door, and initially told her husband only that she had tried to kill herself — not that she had killed the children.
On cross-examination, Reddington challenged Saathoff’s depth of experience with postpartum psychosis, noting the doctor had treated only a small number of such cases decades earlier. Reddington also highlighted that Saathoff first interviewed Clancy more than three years after the events. The exchange grew tense at times, with the defense attorney expressing frustration over the expert’s answers. Yet it was Saathoff’s concession that the prosecution’s opening statement minimized Clancy’s suffering that provided the defense with a memorable closing note to the evidentiary phase.
A Case That Spotlights a Rare Condition
Postpartum psychosis remains poorly understood by the general public. Unlike the more common postpartum depression, it can involve rapid onset of delusions, hallucinations, severe mood swings, and confusion. Experts note that symptoms can wax and wane dramatically — a woman may appear relatively functional one moment and profoundly ill the next. The Clancy trial has forced the condition into broader conversation, with advocates hoping greater awareness will lead to better screening, treatment, and support for new mothers.
Prosecutors have argued that Clancy’s documented efforts to seek help, her ability to function on the day of the killings, her planning in sending her husband away, and her subsequent actions all demonstrate criminal responsibility. The defense counters that those same desperate efforts to obtain care, the polypharmacy, the documented intrusive thoughts, and the sudden emergence of a commanding voice are hallmarks of a woman overwhelmed by untreated or inadequately treated illness.
Clancy herself did not take the stand. She has attended the proceedings in a wheelchair, listening as witnesses recounted the final months of her children’s lives and the night that ended them.
Judge William Sullivan has indicated the jury will receive instructions that include the option of manslaughter in addition to first-degree murder and the possibility of a not-guilty-by-reason-of-lack-of-criminal-responsibility finding. A conviction on first-degree murder carries a mandatory sentence of life without parole under Má´€ssachusetts law.
As the jury prepares to hear closing arguments and begin deliberations, the central question remains the one that has defined the trial from the start: whether Lindsay Clancy, in the depths of what her lawyers describe as a catastrophic postpartum mental health crisis, retained the capacity for the calculated choices the prosecution attributes to her — or whether, as the defense insists and as Saathoff’s own concession underscored, the full measure of her suffering has yet to be adequately weighed.
The courtroom in Plymouth Superior Court has heard five weeks of medical records, 911 recordings, family testimony, and competing expert opinions. On Thursday the lawyers will make their final appeals. Then twelve jurors will decide.
