The Lindsay Clancy Story: A Deep Dive

18 min read By Jarvis

A former Massachusetts nurse strangled her three children in their Duxbury basement, then threw herself from a window. She does not deny it — she says postpartum psychosis did. After a trial that gripped America, a jury is deadlocked. This is the entire story: the family, the seven-month descent, the day, the investigation, the courtroom, and the verdict that hasn't come yet.

A note before you begin. This is a story about the deaths of three children — Cora (5), Dawson (3), and Callan (8 months) — and about a mother, Lindsay Clancy, who does not dispute killing them. A jury is currently deliberating whether she is criminally responsible. Nothing in this article is a verdict; where facts are contested, both sides' positions are presented. If you or someone you know is struggling with postpartum or other mental health concerns, the U.S. Suicide & Crisis Lifeline is 988 (call or text).

I. The Snapshot

On the afternoon of January 24, 2023, Lindsay Clancy strangled her three children one by one in the basement of the family's home at 47 Summer Street in Duxbury, Massachusetts, using exercise bands. She then cut her wrists and neck and threw herself from a second-story window. The fall broke her spine and left her paralyzed from the waist down.

Her two older children, Cora (5) and Dawson (3), were pronounced dead at the hospital that night. The youngest, Callan (8 months), was airlifted to Boston Children's Hospital, declared brain dead, and removed from life support on January 27, 2023.

Clancy, a former labor-and-delivery nurse, pleaded not guilty to three counts of first-degree murder. She does not deny the killings; her defense is that she was suffering from postpartum psychosis and a related mental illness and was not criminally responsible — an insanity defense. After a nearly six-week trial that became one of the most-watched criminal proceedings in the country, a 12-person jury has been deadlocked since early September, with the entire case now hanging on what the defense says is a single holdout juror.

II. The Family: The Clancys of Duxbury

Lindsay Marie Musgrove was born August 11, 1990, in Wallingford, Connecticut — a quiet, well-kept suburb. She grew up a soft-spoken, determined young woman, a former cheerleader with no criminal record, and studied nursing at Quinnipiac University. She went on to work for nine years as a labor-and-delivery nurse at Massachusetts General Hospital (MGH), where colleagues remembered her as "a ray of sunshine" and a "positive light."

She met Patrick Clancy in 2013 through a connection in his extended family. Patrick, a few years older, was from a large Catholic South Shore family — the kind of easygoing, benefit-of-the-doubt-giving man his mother described as "not [someone] who likes to be angry." He worked in technology (software sales at Microsoft) and was a lifelong sailor. They married in December 2016 at a golf-club reception decorated in red and silver for the holidays.

The couple settled in Duxbury, a coastal suburb about 20 miles south of Boston, and built what the family and neighbors described as the "all-American family." They had three children:

Lindsay went part-time after Cora's birth, often working night shifts at MGH, where she liked to check in on her own babies through a video feed on her phone. The family was young, white, well-off, and photogenic — the kind of family, as one profile noted, that "true-crime enthusiasts often find irresistible."

III. The Descent: A Year of Deterioration (May 2022 – January 2023)

Lindsay had reported postpartum anxiety after her first two children. After Callan's birth in May 2022, however, things got markedly worse. What followed was a seven-month cascade of worsening symptoms, dozens of medical visits, and a revolving door of psychiatric medications — a timeline that became the emotional and legal center of the trial.

The symptoms. Lindsay experienced debilitating anxiety, severe insomnia (at points sleeping only about three hours a night), exhaustion, loss of appetite, social withdrawal, and episodes of intense fear. Patrick described finding her in the afternoons "rocking back and forth on the living-room couch, her heart racing," saying she felt "terrified" though he couldn't understand why. She described feeling "like a zombie" and "tired and anxious."

The medications. In the months before the killings, Lindsay was prescribed 13 different psychiatric medications — a fact the defense used to argue she was overmedicated and underserved, and that providers were chasing symptoms rather than a diagnosis. The sequence, roughly:

The disclosures. Both Lindsay's mother, Paula Musgrove, and Patrick testified that Lindsay disclosed thoughts of harming the children at some point in December. Patrick said he asked whether she needed to be separated from them; she said no. He found it confusing because she continued to care for the children normally and he never saw her mistreat them.

McLean Hospital. On December 31, 2022, Lindsay returned to the ER over persistent suicidal ideation. The next morning she voluntarily began inpatient treatment at McLean Hospital, a top-ranked psychiatric institution in Boston. There, psychiatrist Dr. Alia Goodheart diagnosed her with "major depressive disorder, severe, without psychotic features." After several nights of sleep, Lindsay asked to be discharged a day early to attend Cora's birthday party. Goodheart described her as future-oriented and invested in her children. Lindsay left McLean on January 5, 2023.

The final days. The day after her discharge, Tufts described her as "deteriorating." In the month before the killings, Lindsay's phone was used to search for her medications, bipolar disorder, hallucinations, and insomnia — along with searches prosecutors later highlighted: "Where is the carotid artery," "How to slit your throat to die," "Can you turn airbags off on Kia Sorento," and "Can you treat a sociopath?"

On January 23, 2023 — the day before the killings — Lindsay had an appointment with Tufts. Tufts testified she appeared depressed and said she had to force herself out of bed, but denied suicidal or homicidal thoughts, and Tufts observed no signs of psychosis.

The journal. Investigators recovered notebooks in which Lindsay documented her mental state. Her entries described insomnia, intrusive thoughts, a persistent "brain fog," and fear about caring for her children — while also tracking her medications. A November 2022 note read: "I will get through this. I will overcome postpartum anxiety and depression. I am a great mom. I love my kids." Another entry, from the phone's Notes app, read: "I am sad and depressed because I cannot parent my third child like my first. I want to treat every one of my babies like my first. I am sad I stopped breastfeeding. I feel not as connected with Cal now." The defense pointed out that her handwriting deteriorated over time, becoming "little chicken scratches" by January — "her mind was gone," as defense attorney Kevin Reddington told the jury.

IV. The Day: January 24, 2023

By Patrick's account, the morning of January 24 looked, to an outsider, like one of Lindsay's best days. She told him she had slept "pretty well" and felt "good." She had become preoccupied with Cora's stomachache (worried it might be a kidney issue) and took Cora to a pediatrician appointment — a visit the pediatrician later described as "very normal." In the afternoon, Lindsay built a snowman and did art projects with the children. She exchanged routine texts with Patrick, who was working from home.

Then, in the late afternoon, the phone records began:

While he was gone, Lindsay strangled her three children one by one with exercise bands in the basement. She then attempted to kill herself by cutting her wrists and neck and jumping from a second-story window.

In later legal filings, Lindsay said she woke that day with suicidal thoughts and that in the afternoon a male voice began telling her to harm the children. After Patrick left, she said the voice became loud and demanding, repeatedly telling her: "This is your last chance. You have to kill the kids so you can kill yourself." She claimed a force took over and that she "felt an overwhelming, irresistible compulsion to comply."

The discovery

When Patrick came home, the house was "unusually quiet." He called Lindsay's phone at 6:09 p.m. — no answer. He found an upstairs bedroom bloodied and a window open, ran outside, and found Lindsay lying on the ground, injured and semi-conscious. He called 911; police arrived at 6:11 p.m.

Still on the phone with 911, Patrick went back inside and found all three children in the basement, each unconscious and in medical distress, exercise bands still wrapped around their necks. Cora and Callan were on the floor of the basement den; Dawson was alone on the floor of Patrick's home office.

Responders attempted resuscitation. Cora and Dawson were pronounced dead at Beth Israel Deaconess Hospital – Plymouth. Callan, who arrived in cardiac arrest, was flown by helicopter to Boston Children's Hospital, where doctors found he had suffered a severe brain injury from lack of oxygen. He was declared brain dead and removed from life support on January 27, 2023.

Lindsay was taken to South Shore Hospital, intubated, and transferred to Brigham and Women's Hospital. In the early morning of January 25 she went into cardiac arrest, was revived after CPR and multiple blood transfusions, and was left paralyzed from the waist down by her fall. A physician assistant who treated her testified he sutured the cuts on her wrists but that the neck cuts were superficial and did not require intervention.

While still intubated on January 26, Lindsay was interviewed by a forensic psychiatrist. Unable to speak, she communicated by writing. Among the questions she asked: "Do I have an attorney?" "Is my body broken?" "Are my legs straight?" She also asked about visitors and where her family was. She requested a do-not-resuscitate order, which doctors declined given her mental state and recent suicide attempt.

V. The Investigation

Duxbury police responded and brought in the Massachusetts State Police. Investigators reviewed surveillance footage, cell records, internet history, and the couple's communications to reconstruct the final hours. Police executed 11 search warrants, collecting physical, biological, and digital evidence — cameras, laptops, prescription medications, and blood-stain DNA. They also recovered Lindsay's notebooks.

VI. The Legal Battle

Charges. An arrest warrant was obtained January 25, 2023. Lindsay was arraigned via Zoom from her hospital bed on February 7, 2023 and pleaded not guilty. She was held without bail at Tewksbury Hospital. A grand jury indicted her on September 15, 2023 on three counts each of first-degree murder and strangulation; the strangulation charges were dismissed in July 2026 as redundant with the murder counts. She faces a mandatory life sentence if convicted of the murder charges.

The defense strategy. Lindsay's case was led by veteran defense attorney Kevin Reddington. The defense pursued a lack-of-criminal-responsibility (insanity) defense based on postpartum psychosis and other mental illness. In Massachusetts, a defendant can be found not guilty by reason of insanity if, owing to mental illness, she lacked the capacity to "conform her conduct to the requirements of law" — even if she understood what she was doing and knew it was wrong.

Reddington sought a bifurcated trial (one phase on guilt, a second on criminal responsibility) and even offered that Lindsay would "stipulate formally in writing to her involvement" in the deaths so prosecutors wouldn't have to prove them. The prosecution refused to accept any stipulation about "the violent and painful murders," and Judge William Sullivan denied both the bifurcation (March 31) and the stipulation (April 22). A motion to change venue to Boston was also denied.

The trial. It began with jury selection on July 20, 2026 at Plymouth Superior Court; opening statements came July 27. Sullivan seated 18 jurors (12 to deliberate, 6 alternates); the deliberating panel was 3 men and 9 women. The trial ran nearly six weeks, with more than 80 witnesses and over 300 exhibits. The prosecution rested August 17; the defense rested August 26; closing arguments were heard August 27.

The prosecution's case

Assistant District Attorneys Jennifer Sprague and Shanan Buckingham argued Lindsay was in control, and that her actions showed planning and rational thought.

"This was not a woman in the throes of psychosis on January 24, 2023," Buckingham said in opening. "This was a woman who acted intentionally, rationally, and swiftly to accomplish a very specific goal — to kill."

The defense's case

Reddington argued Lindsay was a loving mother who suffered a psychotic break after months of deterioration, and that she was misdiagnosed and improperly treated by providers who failed to coordinate her care.

The closing. Sprague: "There's no dispute that Lindsay Clancy was suffering from mental illness and that she tried to kill herself." Reddington: "These children were loved and nurtured and cared for by her... She loved those children right up to the time of their death."

VII. The Central Question: Postpartum Psychosis

The trial became, in the words of The Guardian, "America's saddest murder trial" — less a straightforward murder case than a national referendum on postpartum mental illness and how the healthcare system recognizes and responds to it.

What it is. Postpartum psychosis is a severe psychiatric emergency affecting roughly 1 to 2 women per 1,000 births, usually within weeks of delivery. It can cause hallucinations and paranoid delusions and, in severe cases, maternal suicide and infanticide. Experts note it is underdiagnosed and that symptoms "wax and wane" — high-functioning new mothers often hide them out of shame, paranoia, or confusion.

The Andrea Yates parallel. The case was repeatedly compared to Andrea Yates, who in 2001 drowned her five young children in a bathtub, believing she was rescuing them from Satan, and was ultimately found not guilty by reason of insanity. Both cases force the same uncomfortable question: was this a mother who was "mad" (very ill) or "bad" (very evil)? As media scholar Barbara Barnett writes, "mad" mothers are routinely exalted as "perfect" and "normal" nurturers "driven to insanity because they cared so much," while "bad" mothers are demonized.

The system-failure argument. Postpartum mental-health expert Dr. Nicole Kumi told the court the trial exposed "a significant gap in care for moms in the postpartum period" and "a maternal healthcare crisis in this country." She emphasized that Clancy was "actively seeking help... She knew something was wrong, but she didn't know what was wrong," and that the fact she had already had three children may have led people to assume she could cope.

"She was crying out for help within her home and within the healthcare system, and all she was met with was medication and redirection," Kumi said.

"Forensic fandom." The livestreamed trial also became a magnet for amateur sleuths on TikTok and social media pushing viral conspiracy theories — most prominently that Patrick Clancy actually killed the children and framed Lindsay. Despite surveillance and phone records corroborating that Patrick was at a CVS during the killings, some theorists have claimed, among other things, that he may have used a "body double." Boston University media scholar Katy Coduto calls the phenomenon "forensic fandom" — people treating a real murder like a puzzle in Lost or Severance, hunting for "Easter eggs" because "it's hard to accept that someone could do something terrible." Experts warn this chilling effect threatens to entrench stigma around postpartum illness and discourage other women from seeking treatment.

VIII. The Aftermath and the Human Cost

Patrick Clancy. Days after the killings — from the hospital where Callan had just been removed from life support — Patrick posted a public statement describing the children as "the essence of my life" and urging the public to forgive Lindsay, whom he characterized as mentally ill rather than malicious. "I wasn't married to a monster — I was married to someone who got sick," he later said. He put the Duxbury home up for sale, relocated to New York City in spring 2023, filed for divorce in February 2024, and in April 2026 married a new partner in a Central Park ceremony. He has continued to publicly support Lindsay's defense.

Lindsay Clancy. She remains paralyzed from the waist down and has been held at Tewksbury Hospital in state custody while awaiting trial. Her parents, Michael and Paula Musgrove, have paid for her defense — Reddington told the Boston Globe "not one cent" from the public GoFundMe went toward it.

The community. Duxbury and surrounding towns were gripped by grief. Residents held vigils and left flowers and stuffed animals near the home; the responding officers were given time off and received an outpouring of support. Duxbury Public Schools offered resources to affected students and families. On the one-year anniversary, a nonprofit hosted a memorial service for the children.

The money. A GoFundMe for Patrick (medical bills, funerals, legal help) raised over $1 million from more than 13,000 donors. In 2026, a second GoFundMe for Lindsay's parents — to help cover the costs they'd incurred over three years — also raised more than $1 million.

The civil lawsuits. In January 2026, Lindsay and Patrick filed separate medical-malpractice suits against the providers who treated Lindsay before the killings:

Both suits remain open.

IX. Where It Stands: The Deadlocked Jury (as of September 4, 2026)

The jury began deliberations on August 27, 2026. They were given five possible verdicts: guilty of first-degree murder, guilty of second-degree murder, guilty of manslaughter, not guilty, or not guilty by reason of lack of criminal responsibility.

What happens next. If the jury ultimately cannot agree, Sullivan could declare a mistrial, which would likely lead to a retrial with a new jury. Reddington has said he does not want a mistrial. The case is, for now, balanced on the scale of one juror.

X. Why It Matters

Whatever the jury decides, the Lindsay Clancy case has already done something: it has forced a national conversation about postpartum psychosis — a real, treatable, and dangerous condition that affects thousands of women and is routinely missed because of how little is understood about it, how strained the mental-health system is, and how fiercely the myth of the "perfect, joyful mother" resists the reality that new mothers can become gravely ill.

It has also laid bare the fault lines in a fragmented healthcare system, where a mother who was actively, repeatedly seeking help — going to ERs, calling hotlines, journaling her decline, asking to be hospitalized — was met, as one expert put it, with "medication and redirection" rather than a unifying diagnosis. And it has exposed the dark side of the true-crime era, where a family's unimaginable tragedy becomes content, and a grieving father becomes a suspect in the court of public opinion.

At the center of all of it are three children — Cora, Dawson, and Callan — and the question a jury is still trying to answer: was this a mother who was ill, or a mother who chose?
