The murder trial of Lindsay Clancy reached a critical stage on Thursday as lawyers presented their closing arguments.
Clancy’s defence urged jurors to conclude that severe postpartum psychosis drove her to kill her three children. Prosecutors, however, argued that Clancy understood her actions were wrong and deliberately carried them out.
The case has drawn national attention to postpartum mental health and the legal questions surrounding criminal responsibility.
Defence Argues Postpartum Psychosis Took Control
Clancy, 36, acknowledges killing her three children in January 2023.
She strangled Cora, 5, Dawson, 3, and Callan, 8 months, with exercise bands inside the basement of her Duxbury home.
Afterward, she cut herself with a knife and jumped from a second-floor window. The suicide attempt left her paralysed.
During his closing argument, defence lawyer Kevin Reddington asked jurors to find Clancy not guilty by reason of insanity.
“Her mind was gone,” Reddington told the jury.
He argued that evidence showed Clancy had struggled with serious mental health problems for months.
According to the defence, she sought treatment while experiencing suicidal thoughts following the birth of her third child.
Reddington also accused prosecutors of presenting evidence in a way that damaged the image of a “young, vibrant, hardworking” mother.
He argued that Clancy acted after hearing a voice, which he attributed to “the damn medicine and the lousy medical care that she got.”
“This young lady is not guilty of the killing of her children because she was suffering from a disease and defect, as his honour instructed you,” he told jurors. “And they’re not going to be able to prove otherwise.”
Prosecutors Challenge Insanity Defence
Assistant District Attorney Jennifer Sprague did not dispute Clancy’s mental health struggles.
However, she argued that those struggles did not answer the central question before the jury.
Sprague said jurors must determine whether Clancy understood that killing her children was wrong on January 24, 2023.
She argued that Clancy nevertheless carried out the killings before attempting suicide.
“This case is not about our mental health system or how it treats women,” she told jurors. “That’s a distraction to get you angry and passionate about an important issue, but an issue that’s not on trial here.”
Sprague also focused on events immediately before the killings.
She said Clancy sent her husband, Patrick, out to collect food and visit a pharmacy.
According to prosecutors, Clancy used her phone to calculate how long the trip would take.
Patrick later spoke briefly with his wife while he was at the pharmacy. When he returned, he found her injured in the backyard.
Clancy told him she had attempted suicide. He then asked where the children were.
She told him they were in the basement. Patrick called 911 before rushing downstairs.
There, he discovered the children with exercise bands around their necks.
Dispute Over the Voice Clancy Reportedly Heard
Several witnesses testified about Clancy’s later claims that she heard a man’s voice.
Patrick, family members and a hospital chaplain said Clancy described hearing a voice telling her she would lose her chance if she did not act.
The defence presented the alleged voice as evidence of her deteriorating mental state.
Prosecutors disputed that account, however, and questioned when Clancy first mentioned hearing it.
Sprague argued that Clancy had not mentioned the voice during her phone conversation with Patrick at the pharmacy.
She also claimed Clancy only discussed the voice after reaching the hospital following her suicide attempt.
According to Sprague, this supported the prosecution’s argument that Clancy deliberately planned her actions.
She said Clancy took the children to the basement one by one before attempting to end her own life.
“It was a choice to take them with her,” Sprague said. “It was a horrific choice. And it’s a choice that we don’t want to think about that a mother made because that doesn’t make us feel safe or comfortable in this world. But it’s a choice she made.”
Jury Begins Deliberations
Following the closing arguments, Judge William Sullivan completed his instructions to the 12 jurors.
He then selected a foreperson and sent the jury to begin deliberations. “It’s not going to be an easy task,” Sullivan told them.
The jury has several possible verdicts available in the case. Clancy could be convicted of first-degree murder, second-degree murder or manslaughter.
If convicted of first-degree murder, she faces life imprisonment without parole. Alternatively, jurors could find her not criminally responsible or not guilty by reason of insanity.
Such a finding would lead to her commitment to a state psychiatric hospital for evaluation.
Case Revives Debate Over Postpartum Mental Health
The five-week trial has also revived wider discussion about postpartum psychosis and mental health treatment. The case has drawn comparisons with Andrea Yates, a Texas woman who killed her five children in 2001.
Yates was initially convicted of murder. However, an appeals court overturned that conviction, and she was later found not guilty by reason of insanity in 2006.
Her defence had argued that she suffered from severe postpartum psychosis. The Clancy case similarly places mental illness and criminal responsibility at the centre of a highly emotional legal debate.
At the same time, the prosecution has urged jurors to focus narrowly on Clancy’s state of mind and actions on the day of the killings.
The jury’s decision will determine whether the court considers Clancy criminally responsible for the deaths of her three children.
