A Massachusetts jury heard testimony that Lindsay Clancy's cellphone contained searches for lethal self-harm methods and psychiatric terms in the days before she strangled her three young children, evidence both sides are now fighting to frame.
Defense attorney Kevin Reddington confronted Massachusetts State Trooper Timothy Chiappini on the witness stand Thursday during day 13 of Clancy's murder trial in a Plymouth County courtroom, pressing the forensic analyst on a series of Google searches recovered from Clancy's phone. Among them: "How to slit throat to die" and "Where is the carotid artery?" Reddington held up posters displaying each search for the courtroom to see, the New York Post reported.
Clancy, a former nurse, is accused of using exercise bands to strangle her three children, Cora, 5; Dawson, 3; and Callan, 8 months old, inside the family's Duxbury, Massachusetts, home on January 24, 2023. She then allegedly slit her own wrists and neck and threw herself from a second-story window. She survived. Her children did not.
The central question at trial is whether Clancy acted deliberately or was in the grip of severe postpartum psychosis made worse by prescription drugs. Prosecutors say her actions reveal a calculated killer who was tired of caring for her children. The defense says she was not criminally responsible.
Reddington's cross-examination of Chiappini produced a strange exchange. When asked whether he had encountered the search "Where is the carotid artery?" on the phone, Chiappini told the jury, "I don't recall." Pressed further on whether the searches came from Clancy's device, he said, "I can't confirm that."
But Reddington then pointed to a phone identifier number on the records introduced at trial, a number that matched the identifier from Chiappini's own forensic review of Clancy's phone. Chiappini agreed it was "a pretty good inference" that the searches originated from her device.
The exchange highlighted a recurring tension in digital forensic testimony: analysts can confirm what a device accessed, but tying a specific person to a specific search requires an additional logical step. Reddington appeared to use that gap not to cast doubt on the searches, but to walk the trooper into acknowledging them on the record.
When the trial began with jury selection earlier this summer, both sides signaled that digital evidence would play a central role. Thursday's testimony bore that out.
Chiappini's testimony laid out a timeline of searches that grew darker as January 24 approached. On January 19 and 20, 2023, just days before the killings, Clancy searched for information about schizophrenia, psychosis, "hallucinations," and "intrusive." On January 20, she searched "Can you treat a sociopath."
In the weeks before the killings, her phone also showed multiple searches for trazodone, Zoloft, "benzo withdrawals," "postpartum depression," and "bipolar disorder." Those searches align with what the defense has argued throughout the trial: that Clancy was a woman overwhelmed by psychiatric symptoms and desperately trying to understand what was happening to her.
That framing gained additional support from AP News reporting that a forensic psychiatrist diagnosed Clancy with bipolar disorder and postpartum psychosis after the killings, and that she had sought extensive mental health help, including outpatient providers, a suicide hotline, emergency room visits, and a psychiatric hospital stay, before January 24.
Prosecutors read the same evidence differently. They contend the searches show a woman gathering information, not spiraling out of control. The prosecution's stated theory is that Clancy "deliberately and meticulously" killed her children and "acted intentionally, rationally, and swiftly to accomplish a very specific goal," as Fox News reported from earlier trial proceedings.
The defense has also argued that Clancy's psychiatrist never saw her in person before the killings, raising questions about the quality of care she received. Five doctors prescribed her as many as 12 different medications, including Zoloft, Valium, Prozac, Klonopin, and Ambien.
A second state police witness, Sgt. Kyle Pavao, testified Thursday about evidence recovered from Clancy's Microsoft Surface Pro tablet. Pavao told the jury that the tablet had accessed a website entitled "suicide methods" in August 2022, roughly three months after Clancy gave birth to Callan, the youngest of the three children.
The page was reached through a series of clicks beginning on a Wikipedia entry about Tom Hall, an American singer who died by suicide in 2021. But Pavao could not confirm that Clancy herself had visited the page, only that it was accessed on the device.
That distinction matters. Patrick Clancy, Lindsay's then-husband, previously testified that he was the one who searched for Tom Hall. If the jury believes him, the tablet evidence does not tie Lindsay Clancy to the suicide-methods page at all.
Patrick Clancy's earlier testimony described what he called his wife's "big spiral" in the months before the killings. He returned home on January 24, 2023, to find all three children dead.
The jury also heard a journal-like entry Clancy wrote in her phone's Notes app on November 3, 2022, about two and a half months before the killings.
"I really want a fourth child but I need a good therapist before then."
The note captures a woman who recognized she needed help, and who, at least at that point, was still thinking about a future with more children. An earlier personal note from October 2022, reported by the AP, struck a similar tone: "I'm terrified of something happening to my kids or doing something wrong to mess up their development."
The defense has used entries like these to argue that Clancy was not a cold-blooded killer but a mother losing a battle with severe mental illness while the medical system around her failed. The prosecution sees a different story in the same words, a woman who understood her situation clearly enough to articulate it, plan around it, and ultimately act.
The jury also viewed text messages exchanged between Clancy and Patrick in the moments before he returned home on January 24. The content of those messages was not disclosed in detail, but they were described as ordinary in tone, the kind of texts any couple might exchange at the end of a day. Patrick texted her, "You're a good mamma," according to AP reporting.
Earlier in the trial, Clancy broke down sobbing during autopsy testimony about her daughter Cora, telling the courtroom, "I can't do this." Judge William Sullivan ordered a recess and excused the jury.
What makes the Clancy trial unusual is not the volume of digital evidence, phone forensics are routine in murder cases, but the fact that both the prosecution and the defense want the jury to see the same searches and reach opposite conclusions. The defense needs the jury to read "Can you treat a sociopath" and "hallucinations" as the desperate queries of a woman unraveling. The prosecution needs the jury to read "How to slit throat to die" and "Where is the carotid artery?" as research.
Neither side disputes that Clancy killed Cora, Dawson, and Callan. The only question is whether she was legally responsible when she did it. The defense is seeking a verdict of not guilty by reason of insanity.
Three children are dead. The system that was supposed to help their mother, the doctors, the prescriptions, the emergency room visits, did not stop what happened. Whether that failure is a defense or just a tragedy is now in the jury's hands.
