In a Plymouth courtroom, the trial of Lindsay Clancy has turned toward the interior landscape of a mother's mind — asking whether the deaths of three young children in January 2023 were the product of deliberate cruelty or the catastrophic unraveling of a woman consumed by postpartum psychosis. Her mother, her sister, and a former colleague each stepped forward to describe a woman who was visibly deteriorating in the months before the tragedy, while prosecutors pressed on the silence between concern and action.

Clancy's mother testifies daughter had thoughts of harming children before killings
Three children—Cora (5), Dawson (3), and Callan (8 months)—were killed in their Duxbury home on January 24, 2023. Their mother Lindsay Clancy survived a suicide attempt.
She told us that she had thoughts of harming the children.
Mark
Why does the mother's testimony matter so much here? She's not a doctor.
Mimi
Because she's the first person Clancy told about these thoughts. If the jury believes Clancy disclosed intrusive thoughts months before the deaths, it supports the defense's argument that this wasn't a calculated plan—it was a deteriorating mental state.
Mark
But the prosecutor showed texts where Clancy said she was feeling better in January. Doesn't that undercut the defense?
Mimi
That's the tension the jury has to sit with. The prosecution is saying: if she was so sick, why did she tell her mother she was improving? The defense will likely argue that postpartum psychosis can mask itself, that people can seem fine on the surface while experiencing something catastrophic underneath.
Mark
The sister said Clancy seemed off at Thanksgiving, but then told police two weeks before the deaths that Clancy seemed okay. How does that help the defense?
Mimi
It doesn't, directly. But the defense is building a picture of someone whose condition was worsening over months, not someone who woke up one day and decided to kill her children. The inconsistencies in how family members perceived her might actually support a mental illness narrative—these conditions can be invisible.
Mark
What about the phone searches? Searching for postpartum psychosis symptoms seems like she knew something was wrong.
Mimi
Exactly. The defense will argue those searches show Clancy was trying to understand what was happening to her, reaching for answers. The prosecution will say they show premeditation. The jury has to decide which story the evidence tells.
Mark
If she's found not criminally responsible, does she go free?
Mimi
No. She goes to a state psychiatric hospital in Massachusetts. She doesn't walk out the door. The difference is whether she's imprisoned or hospitalized—and whether she's labeled a murderer or a woman who committed acts while psychotic.
El Pulso
- Three children — Cora, Dawson, and Callan — were killed in their Duxbury home in January 2023, and their mother Lindsay Clancy now faces either life without parole or psychiatric hospitalization depending on what the jury believes about her state of mind.
- The defense opened with Clancy's own mother on the stand, who testified that her daughter disclosed intrusive thoughts about harming her children as far back as October 2022 — more than three months before the deaths.
- Prosecutors struck back with text messages showing Clancy told her mother she was feeling better just days before the killings, and challenged why no one sought psychiatric intervention despite their stated fears.
- Phone searches — including 'symptoms of postpartum psychosis' just five days before the deaths — are being read in opposite directions: by the prosecution as evidence of planning, by the defense as the desperate self-diagnosis of a deteriorating mind.
- Expert witnesses on postpartum psychosis are expected to take the stand next, and their testimony may ultimately determine whether this case is understood as a crime or a medical catastrophe.
In a Plymouth courtroom, the trial of Lindsay Clancy has turned toward the interior landscape of a mother's mind — asking whether the deaths of three young children in January 2023 were the product of deliberate cruelty or the catastrophic unraveling of a woman consumed by postpartum psychosis. Her mother, her sister, and a former colleague each stepped forward to describe a woman who was visibly deteriorating in the months before the tragedy, while prosecutors pressed on the silence between concern and action. The case now rests on one of the oldest and most difficult questions the law must face: where does illness end and culpability begin.
Lindsay Clancy's murder trial entered its defense phase on Monday at Plymouth Superior Court, with her mother Paula Musgrove taking the stand for more than two hours. Musgrove described a daughter who had been a devoted mother but who began to unravel in early October 2022 — sending frightened text messages about insomnia, medication, and a feeling that something was deeply wrong. In a conversation that month with Musgrove and Clancy's husband Patrick, Clancy disclosed that she was having thoughts of harming her children. That disclosure came more than three months before January 24, 2023, when Cora, 5, Dawson, 3, and Callan, 8 months, were killed in the family's Duxbury home. Clancy survived a suicide attempt the same day.
Prosecutors used cross-examination to complicate the picture. Assistant DA Jennifer Sprague presented text messages from January 2023 in which Clancy told her mother she was feeling better, and pointed to a weekend social gathering just days before the deaths. Sprague questioned why Musgrove, despite her concern, had never sought to have her daughter psychiatrically committed. Musgrove said she had not considered it, and that a message she sent praising her daughter's improvement was meant as encouragement rather than a genuine assessment.
Clancy's sister Allison Ozga also testified, recalling that Clancy seemed visibly diminished at Thanksgiving and described herself as being in 'a really tough spot' in December. Yet Ozga, too, had told police two weeks before the deaths that her sister seemed fine — a contradiction Sprague pressed on in cross-examination.
A former nursing colleague testified about a conversation years earlier in which Clancy had wept upon learning about Andrea Yates, the Texas mother found not guilty by reason of insanity after drowning her five children. 'How could a mother hurt her children?' Clancy had asked. The defense also highlighted phone searches from January 2023, including a search for 'symptoms of postpartum psychosis' on January 19. Prosecutors argue these searches, combined with evidence that Clancy sent her husband on errands to be alone with the children, point to premeditation. The defense contends they are the traces of a woman in the grip of a severe mental illness she could not control.
If convicted of first-degree murder, Clancy faces life without parole. If the jury finds her not criminally responsible, she would be committed to a state psychiatric hospital. Expert witnesses on postpartum psychosis are expected to testify next.
The courtroom in Plymouth Superior Court filled on Monday as Lindsay Clancy's trial entered a new phase. The prosecution had finished laying out its case—that Clancy, 36, deliberately planned to kill her three children and staged a suicide attempt to cover it up. Now the defense was calling its first witnesses, beginning with the person who knew Clancy longest: her mother.
Paula Musgrove took the stand around midday and testified for more than two hours. She described her daughter as a devoted mother, but said something shifted in early October 2022. Clancy had sent her a text message that month, asking her mother to come stay with her. "Mom will you please come up and stay with me for a bit," Clancy wrote. "I'm really sick. Something is wrong. I had horrible insomnia all night and I just don't know how I'm going to get through the day. I started taking the medicine my doctor prescribed for anxiety and I think it's made things worse. It's just really scary and I don't want to be alone."
Musgrove recalled a conversation with Clancy and her husband Patrick around that same time. Clancy had been nervous, her mother said, and had something important to tell them. "She told us that she had thoughts of harming the children," Musgrove testified. This disclosure came more than three months before January 24, 2023, the day Clancy's three children—Cora, 5; Dawson, 3; and Callan, 8 months—were killed in their Duxbury home. Clancy survived a suicide attempt that same day.
The prosecution's cross-examination, led by Jennifer Sprague, pressed on a different narrative. Sprague presented text messages from January 2023, just weeks before the deaths, in which Clancy told her mother she was doing "good" and feeling "a little bit" better. On January 22, after a weekend that included a friend's party, Musgrove had written to her daughter: "Enjoyed seeing everybody this weekend. Nice to see you doing better." When asked about that message, Musgrove explained it was meant as encouragement, not necessarily a reflection of what she actually observed. She said she was trying to support her daughter in getting back to normal.
Sprague also questioned why, if Musgrove was concerned enough about Clancy's safety to stay at the house, she had never sought to have her daughter committed to a psychiatric facility. Musgrove said she had not considered it. When pressed about a police interview the day after the children died, Musgrove said she could barely remember it—she was in shock. She could not recall telling officers that Clancy "seemed brighter lately."
Clancy's sister, Allison Ozga, also testified for the defense. She said that when she came home for Thanksgiving in November 2022, she noticed her sister's mood was noticeably different. "Her mood did not look good, her energy wasn't high. Definitely seemed off from how I saw her in the past," Ozga said. In December, Clancy had told her sister she was in "a really tough spot." Yet on cross-examination, Sprague noted that Ozga had told police two weeks before the deaths that Clancy seemed fine, and that Ozga had never filed a report expressing concern for the children's safety.
The defense also called Margaret Hamp, a labor and delivery nurse who had worked with Clancy at Massachusetts General Hospital. Hamp testified about a conversation they had years earlier, when Clancy was shocked to learn about a pregnant patient who had expressed plans to harm herself. Hamp had asked if Clancy knew about Andrea Yates, the Houston mother who drowned her five children in 2001. Yates was initially convicted but later found not guilty in a retrial after evidence of postpartum psychosis emerged. According to Hamp, Clancy had cried and asked, "How could a mother hurt her children?"
The trial's digital forensics expert, Ian Whiffin, testified about searches on Clancy's phone in the weeks before the deaths. On January 12, she had searched "how does Wellbutrin work for depression?" and "how to tell if you're sleep deprived – or depressed." On January 19, she searched "symptoms of postpartum psychosis." Prosecutors say these searches, along with evidence that Clancy sent her husband to CVS and a restaurant to give herself time alone with the children, show premeditation. The defense is building a different argument: that Clancy was suffering from a severe mental illness that made her not criminally responsible for her actions. If convicted of first-degree murder, she faces life without parole. If the jury finds her not criminally responsible, she would be sent to a state psychiatric hospital.
