PLYMOUTH, Mass. — The trial of Lindsay Clancy, the Duxbury mother accused of killing her three children, is entering its fourth week, with the Commonwealth resting its case Monday in Plymouth Superior Court.
Jurors were given Friday off before returning for what could be a pivotal week in the high-profile case against Lindsay Clancy.
The prosecution called its last witness to the stand, Ian Whiffin, from Cellebrite. Whiffin examined Clancy’s iPhone 13 Apple data the day of the murders.
The prosecution has called nearly 70 witnesses in the last two weeks.
Margaret Hamp was the defense’s first witness. Hamp, who worked at Mass General Hospital, described working with Clancy for many years in the delivery room.
Allison Ozga, Clancy’s sister, spoke about her sister’s mental health struggles, and observed “her decline.” They saw each other around the holidays and at Cora’s birthday following Clancy’s release from McLean Hospital.
Her mother, Paula Musgrove, told the jury that in December, Clancy told her and her husband, Patrick, that she had thoughts of harming the children.
The prosecution is now cross-examining Musgrove.

What jurors heard last week
When court was last in session, testimony focused heavily on data extracted from Clancy’s cellphone.
Jurors were shown evidence that included internet searches related to psychosis symptoms, hallucinations, and suicide in the days leading up to the killings.
Prosecutors also presented crime scene video from inside the Clancy family home.
Among the most emotional moments was the introduction of a photograph showing two of Clancy’s children, Dawson and Cora, posing with a backyard snowman. The picture was taken just hours before the murders, according to testimony.
A diary-style note written by Clancy was also entered into evidence. In the note, she described struggling to feel connected to one of her children and wrote that she wanted to be happy.
Legal experts weigh significance of note
Legal analyst Elyse Hershon said each side could interpret the journal entry differently.
“This note corroborates one piece of the prosecution’s theory, which is that she was an overwhelmed mother, she resented her kids, and she didn’t want to continue like this,” Hershon said.
At the same time, Hershon noted the defense may view the document as evidence of Clancy’s awareness of her mental and emotional struggles.
“I think it’s great for the defense. It shows that she’s human, she’s aware of how she felt,” Hershon said.
What’s next?
Monday marks the 14th day of testimony in the trial.
Court is scheduled to resume at 9 a.m., with prosecutors expected to continue presenting witnesses and evidence as they work to conclude their case before the defense begins its own presentation.
The trial continues in Plymouth Superior Court.
