A hospital chaplain who spent hundreds of hours with Lindsay Clancy after the deaths of her three children delivered emotional testimony Thursday, describing one of the first statements Clancy made after she was able to speak.
Sheila Cavanaugh, a chaplain at Brigham and Women’s Hospital in Boston, testified that she met with Clancy more than 200 times following the January 2023 killings. During one of their earliest conversations, Cavanaugh said Clancy told her, “I am so glad my children are safe.”

The statement came roughly a week after Clancy fatally strangled her three children at the family’s home in Duxbury, Massachusetts, before cutting her wrists and jumping from a second-story window in what authorities described as an apparent suicide attempt.
Clancy is now on trial for the deaths of her children, 5-year-old Cora, 3-year-old Dawson and 8-month-old Callan.
Cavanaugh took the witness stand Thursday, Aug. 20, as a defense witness in the closely watched murder trial. Her testimony offered jurors a deeply personal account of Clancy’s condition in the days and weeks following the tragedy, while also becoming another point of tension between the defense’s argument about postpartum psychosis and the prosecution’s claim that Clancy understood what she was doing.
When Cavanaugh first encountered Clancy at the hospital, Clancy was intubated and unable to communicate. But about a week after the killings, once the breathing tube had been removed, Cavanaugh said she was holding Clancy’s hand when the mother finally spoke to her.
According to Cavanaugh, Clancy expressed relief that her children were safe.
“I am so glad my children are safe,” Clancy said, according to the chaplain’s testimony.
Cavanaugh said she responded from a religious perspective, telling Clancy that the children were “safe in heaven.”
The moment became particularly significant because of the defense’s broader argument that Clancy was experiencing a severe psychiatric crisis when she killed her children. Her attorneys have acknowledged that she was responsible for the physical acts but argue that she was not criminally responsible because she was suffering from postpartum psychosis and was affected by psychiatric medications.
Cavanaugh also described another disturbing aspect of her conversations with Clancy.
The chaplain testified that Clancy told her she had heard a voice in her head. According to Cavanaugh, Clancy believed that if she did not obey the command she was hearing, neither she nor her children would be safe.
That testimony appeared to support the defense’s theory that Clancy’s actions were influenced by hallucinations and delusional thinking rather than a rational decision to kill her children.
But prosecutors highlighted an important issue during cross-examination.
Cavanaugh acknowledged that she did not document Clancy’s statement about hearing voices in her records from their meetings.
That omission gave prosecutors an opportunity to challenge the reliability and timing of the account, particularly because Cavanaugh had met with Clancy so many times after the killings.
The prosecution has consistently argued that Clancy deliberately killed her children and that she understood the difference between right and wrong at the time.
The defense, meanwhile, has presented testimony from multiple mental-health professionals who described a dramatic deterioration in Clancy’s psychological state before the killings. Their testimony has focused on symptoms including hallucinations, paranoia, severe depression and what they believe was postpartum psychosis.
The competing interpretations of Clancy’s mental state have become the central issue in the trial.
For the defense, Cavanaugh’s testimony about the voice Clancy reportedly heard could help reinforce the argument that she believed she was acting under an outside command and feared something terrible would happen if she disobeyed.
For prosecutors, however, statements such as Clancy saying that her children were “safe” could be viewed differently, particularly when considered alongside other evidence about her behavior before and after the killings.
Cavanaugh was the only witness called before the jury was sent home early Thursday.
After jurors left the courtroom, Judge William Sullivan held a preliminary conference with attorneys regarding potential instructions that could eventually be given to the jury.
The testimony comes as the trial enters its final stages after weeks of emotionally charged evidence.
Clancy does not dispute that she killed her three children. The question before the jury is whether she should be held criminally responsible for those deaths.
Prosecutors are seeking to establish that she knew what she was doing and understood that it was wrong. The defense is attempting to convince jurors that Clancy’s mental state had deteriorated so severely that she could not be held legally responsible for her actions.
As closing arguments approach, testimony like Cavanaugh’s could become increasingly important. The jury will ultimately have to weigh the accounts of Clancy’s behavior against the psychiatric evidence and decide whether the prosecution has proved criminal responsibility beyond the required legal standard.
The case has attracted widespread attention because of the difficult questions it raises about postpartum mental illness, psychiatric treatment and criminal responsibility — and Cavanaugh’s testimony provided jurors with another intimate glimpse into Clancy’s state of mind immediately after the deaths of her children.
