PLYMOUTH, Mass. (AP) 鈥� In the months after the birth of her third child, ‘s mental health collapsed. Manic, unable to sleep and stricken with thoughts of harming herself, she sought care from experts in postpregnancy mood disorders, was put on multiple psychiatric medications, and when nothing worked, checked in to a psychiatric hospital.
Nineteen days after she was discharged, she strangled her three children at their Massachusetts home.
A jury heard opening statements Monday in Clancy鈥檚 murder trial, which is expected to feature dueling views in the coming weeks about her culpability and mental state. Jurors also heard testimony from Patrick Clancy, her former husband, who found the children after returning to the house on the day of their killings in January 2023. He has said in interviews that he forgives his wife.

He also found his wife, who had used multiple methods to try to end her own life. She remains paralyzed from the waist down after jumping from the home鈥檚 second-story window.
Lindsay Clancy鈥檚 lawyer, Kevin Reddington, said she was suffering from postpartum psychosis, a rare mental illness linked to the stress, sleep deprivation and hormonal changes that follow childbirth. He described walls decorated with alphabet letters, colors and cartoon characters and a home filled with toys, saying jurors would hear testimony from family, friends, neighbors and teachers about Clancy鈥檚 devotion to her children.
鈥淭hese children were loved, nurtured and cared for,鈥� he told jurors. 鈥淪he loved those children right up to the time of their death.鈥�
Prosecutor Shanan Buckingham argued that Clancy, a former labor and delivery nurse at Massachusetts General Hospital, 鈥渁cted intentionally, rationally and swiftly鈥� and bore full responsibility for the deaths.
鈥淭his was not a woman in the throes of psychosis,” Buckingham said, urging jurors to focus on Clancy鈥檚 actions rather than broader questions about maternal mental health. 鈥淭his is not a public debate about women鈥檚 mental health and how the medical system treats women. This case is about this defendant, Lindsay Clancy.鈥�
The trial will hinge on Clancy’s mental state
Both sides agree she killed her children. They disagree over whether she should be held criminally responsible for their deaths.
Elyse Hershon, a Boston criminal defense attorney and legal analyst, said the verdict will likely depend on how the jury views Clancy鈥檚 鈥渋ntent and mental capacity.鈥�
鈥淲henever there are deaths of children, it rattles emotions. Because these actions are incomprehensible and the outcome so horrific, people tend to want to hold someone responsible,鈥� Hershon said. 鈥淪ome people naturally will identify and sympathize with Clancy and her postpartum depression, and others will not be able to understand how one could end their children鈥檚 lives, and demand responsibility.鈥�
While postpartum depression among women who have given birth, postpartum psychosis is estimated to afflict only 1 to 2 per 1,000 women after delivery. Symptoms include hallucinations, delusions, paranoia, mood changes and thoughts of harming yourself or others. Most women who have the condition, however, do not wind up harming their children.
Prosecutors say Clancy strangled her children 鈥� Cora, 5, Dawson, 3, and Callan, 8 months 鈥� on Jan. 24, 2023, after sending her then-husband, Patrick, out for some errands. She then used multiple methods to try to end her own life and was paralyzed from the waist down after jumping from the home鈥檚 second-story window.
At the time, she had been getting psychiatric care for about four months. On the day of the killings, she said she heard voices telling her, 鈥淭his is your last chance. Kill the children so you can kill yourself,鈥� according to her lawyer.
If convicted of murder, Clancy faces life in prison without parole. If found not guilty due to a lack of criminal responsibility, she would be committed to a state mental health facility.
Similar cases have led to insanity verdicts
The case has parallels to several other mothers accused of killing their children.
In 2001, Andrea Yates drowned her five children in a bathtub in Texas. Her attorneys said she suffered from severe postpartum psychosis and, in a delusional state, believed Satan was inside her and that killing the youngsters would save them from hell.
Her initial murder conviction was overturned, and in a retrial she was found not guilty by reason of insanity and committed to a state mental hospital.
Another Texas mother, Dena Schlosser, was found not guilty by reason of insanity in 2006 after she killed her 10-month-old daughter by cutting off her arms.
Dr. Nicole Cirino, the director of the division of reproductive psychiatry at Baylor College of Medicine, who has been an expert defense witness in infanticide cases, said many of the women who harm their children while in the grip of postpartum psychosis believe their actions are helping the child.
In their own minds, 鈥渢hey may be saving their children from damnation,鈥� Cirino said.
Experts say postpartum psychosis is still poorly understood in the legal system
Clancy and her former husband, Patrick Clancy, filed lawsuits accusing her medical providers of failing to properly diagnose and treat her condition.
Awareness about postpartum psychosis has grown since the Yates case, but Cirino and other maternal mental health advocates said prosecutors rarely consider a mother’s mental state. Illinois is the only state with a law allowing for undiagnosed or untreated postpartum depression or postpartum psychosis to be a mitigating factor in sentencing.
鈥淲omen who kill their children in the throes of this medical illness, postpartum psychosis, are seriously and profoundly mentally ill. They are not evil,鈥� said Dr. Catherine Birndorf, the CEO and founder of The Motherhood Center in New York City, which treats mothers with perinatal mood and anxiety disorders.
鈥淭o me it鈥檚 illness until proven otherwise,鈥� she continued. 鈥淭he fact that we consider it criminal until proven otherwise is problematic.鈥�
