Lindsay Clancy's Mother Testifies: A Family's Account of Mental Decline Before the Killings
The mother of Lindsay Clancy, the 36-year-old Massachusetts woman who strangled her three children in January 2023, testified for the defense on Monday in Plymouth, describing a months-long descent into paranoia, suicidal thoughts, and cognitive breakdown that she says she witnessed firsthand in the weeks before the killings.
Paula Musgrove took the stand as one of the defense's first witnesses after the prosecution rested following three weeks of evidence. Her testimony came the same day the prosecution concluded its case with digital forensic expert Ian Whiffin, who examined Clancy's cellphone search history, calls, text messages, and health data.

Clancy killed her three children, Cora, five, Dawson, three, and Callan, eight months, on 24 January 2023. She has not denied fatally strangling them. She pleaded not guilty to murder by reason of insanity, or what Massachusetts law calls a lack of criminal responsibility. If convicted of first-degree murder, she faces life in prison without parole. If found not guilty due to lack of criminal responsibility, she would be committed to a state psychiatric hospital.
Musgrove's testimony traced a timeline of deterioration beginning the previous October. On 20 October 2022, three months before the killings, Musgrove received a text from her daughter: "I'm really sick. Something is wrong." Lindsay wrote that the medicine she had been prescribed for postpartum depression was not helping. Musgrove drove to Clancy's home in Duxbury and stayed for a week.
Through November and December, Musgrove told the court, her daughter's condition worsened. Clancy was losing weight and becoming "paranoid." She told her mother the medication was "destroying" her mind. At one point she asked if she could sleep in her mother's bed.

Clancy told her mother and her husband, Patrick Clancy, "I want to tell you guys something," and then said "she had thoughts of harming the children." On another occasion, Musgrove testified, her daughter said "this wasn't her mind" and "this isn't me. I just want to feel better and enjoy my kids again." By January 2023, Clancy told her mother she couldn't remember anything. ABC7
The defense also called Clancy's sister, Allison Ozga, who testified that she learned in the months before the killings that her sister was having suicidal thoughts. "She's feeling numb, she's feeling hopeless," Ozga told the court.
Patrick Clancy, who testified earlier in the trial, told the court that his former wife had told him she had no plans to hurt the children. After the killings, while in hospital, Lindsay told him she "heard a man's voice telling her that if she didn't do it now, she would lose her chance."
The defense's strategy is now visible. Massachusetts recognizes a lack-of-criminal-responsibility defense, which works differently from some states' insanity rules. Once the defense raises it, the burden shifts to the prosecution to prove beyond a reasonable doubt that the defendant possessed the criminal intent required for the crime at the time of the act. The testimony from Musgrove and Ozga is being used to establish a documented trajectory of psychotic symptoms, suicidal thoughts, and command hallucinations (hallucinations in which a person hears voices instructing them to act), building toward the argument that Clancy was unable to appreciate the wrongfulness of her conduct.
The prosecution's case, by contrast, appears anchored in the digital record extracted from Clancy's phone. Whiffin's examination of her search history, communications, and health data likely serves to construct a competing timeline, potentially showing premeditation or awareness that cuts against the insanity claim. The specific content of those searches and messages has not yet been detailed in the testimony reported.
The trial's stakes are binary under Massachusetts law. A first-degree murder conviction means life without parole. A finding of no criminal responsibility means involuntary commitment to a state psychiatric facility, with potential for eventual release under supervised conditions. There is no middle verdict available to the jury.
The defense faces a steep evidentiary burden. While family testimony can vividly document behavioral decline, Massachusetts courts have historically required defendants invoking lack of criminal responsibility to show that mental disease or defect rendered them substantially incapable of appreciating the criminality or wrongfulness of their conduct. The prosecution will likely argue that Clancy's communications, search history, and actions on the day of the killings, including the sequencing and the interval between deaths, show planning and awareness inconsistent with a claim of total cognitive collapse.
What the jury must ultimately weigh is whether the documented deterioration Musgrove and Ozga described, accumulating over three months and culminating in Clancy's reported memory loss and auditory hallucinations, meets the legal threshold for extinguishing criminal responsibility or whether the prosecution's digital evidence tells a different story.
