Woman Strangles Three Children in Massachusetts Home Days After Hospital Discharge

Lindsay Clancy, a 35-year-old former nurse from Duxbury, Massachusetts, is on trial for murdering her three young children on January 24, 2023. She strangled Cora, age 5, Dawson, age 3, and eight-month-old Callan — just 19 days after being discharged from a psychiatric hospital. KALB and WFSB report that opening statements began July 27, 2026, in Plymouth Superior Court.
Clancy has pleaded not guilty to three counts of first-degree murder. Her defense argues she was suffering from severe postpartum psychosis and was failed by the medical system. Prosecutors say she acted with cold, deliberate calculation. The case has sparked a national debate about maternal mental health care in the United States.
Clancy voluntarily checked into McLean Hospital in Belmont, Massachusetts, on January 1, 2023. She was discharged just five days later, on January 5. Her discharge paperwork, signed by her doctor, described her judgment and insight as "limited." Nineteen days after leaving the facility, she strangled her three children with exercise bands in the family basement, according to WCAX.
In the months before the killings, Clancy had been prescribed 13 different psychiatric medications in just four months. Her defense says doctors failed to diagnose her true condition: bipolar disorder with postpartum onset. Antidepressants given to someone with unmanaged bipolar disorder can trigger psychosis. Her journal entries from mid-January 2023 recorded command hallucinations telling her to "harm," according to WCTV.
Patrick Clancy later described January 24, 2023, as "one of her best days." Lindsay played with the children and made lunch. At 5:10 PM, Patrick left to pick up takeout and a prescription. At 5:54 PM, Lindsay called him. They spoke for exactly 14 seconds. She showed no signs of distress. Patrick returned home at 6:09 PM and found blood on the floor, reports WITN.
He found Lindsay paralyzed in the backyard. She had slashed her neck and wrists, then jumped from a second-floor window. He discovered the children in the basement. Prosecutors say those 14 seconds prove she was in control — she bought time by sending Patrick away. The defense says her suicide attempt, which left her permanently paralyzed from the waist down, proves she had no rational grip on reality, according to WRDW.
Assistant District Attorney Shanan Buckingham told the jury Clancy "acted intentionally, rationally and swiftly." Prosecutors say she used internet searches to calculate how long Patrick would be away. Defense attorney Kevin Reddington fired back, saying "these children were loved, nurtured and cared for" and called the murder charges an attempt to "kill the soul of this young woman," according to KPTV.
Patrick Clancy, now Lindsay's ex-husband, took the stand as the prosecution's first witness. He has publicly forgiven her. He testified: "I never saw Lindsay harm the kids." Under Massachusetts law, once an insanity defense is raised, the state must prove beyond a reasonable doubt that the defendant understood her actions were wrong. That is a high bar for prosecutors, reports FOX10.
Postpartum psychosis affects 1 to 2 in every 1,000 births. It is not the same as postpartum depression. It can cause hallucinations, delusions, and a complete break from reality. Reproductive psychiatrist Dr. Catherine Birndorf said publicly: "This is not a monster. This is someone who has lost touch with reality for psychiatric reasons." Advocates warn that framing Clancy as calculating could deter mothers from seeking help, according to WABI.
Both Lindsay and Patrick Clancy have filed separate civil lawsuits against McLean Hospital and other providers. If Clancy is found not guilty by reason of insanity, legal experts say it could set a major precedent for how courts treat postpartum psychiatric disorders. The trial is being heard by 18 jurors, including alternates, before Judge William Sullivan in Plymouth Superior Court, reports KSWO.
