Before the trial, the juror said she knew relatively little about the case. She explained that she does not regularly follow the news and therefore had not closely tracked the nationally publicized investigation.
When deliberations began, however, she was initially on the side of the prosecution.
‘Originally, I felt that she was guilty and she was criminally responsible for it.’
That initial conclusion would eventually change.
Even after casting her vote in favor of an insanity acquittal, Juror No. 5 acknowledged that she continued to struggle with the complicated questions surrounding the case.
‘Maybe I still believe that Clancy is guilty, in a certain way,’ she admitted.
Clancy, 36, faced charges in connection with the January 2023 deaths of her three children—Cora, 5, Dawson, 3, and Callan, 8 months—inside the family’s home in Duxbury, Massachusetts.
Clancy acknowledged strangling the children with exercise bands. Her defense team argued, however, that she was suffering from postpartum psychosis and was so severely impaired that she could not appreciate the moral or legal wrongfulness of her conduct.
Prosecutors rejected that argument and maintained that Clancy remained criminally responsible for the killings.
For Juror No. 5, some of the most emotionally devastating evidence initially appeared to support the prosecution’s position.
Among the evidence presented to the jury was a 911 call made by Clancy’s husband, Patrick, after he discovered the children.
The recording was played for jurors during the trial but has not been publicly released.
‘I will never be the same after that 911 call,’ the juror said.
The emotional impact of that recording also led Juror No. 5 to reject online theories alleging that Patrick Clancy was responsible for the children’s deaths and had somehow attempted to frame his wife.
She described the reaction captured in the emergency call as overwhelming.
‘If these people could have heard that visceral, blood-curdling scream,’ she said. ‘It was horrifying.’
But as the jury worked through the testimony and evidence, Juror No. 5 said her understanding of Clancy’s mental condition began to change.
Rather than viewing the case solely through the horrifying consequences of the children’s deaths, she said she increasingly focused on whether prosecutors had established beyond a reasonable doubt that Clancy possessed the necessary criminal responsibility.
‘I think this was a woman who was not mentally healthy, she was in the throes of a significant mental crisis,’ the juror said.
‘I really just felt like she was so deep in it that she couldn’t see her way out, and this was the only option.’
Eventually, the juror concluded that reasonable doubt remained.
That distinction became critical. The issue before the jury was not whether the children had died or whether Clancy had caused their deaths. Rather, jurors had to determine whether the prosecution had proven the required criminal responsibility in light of the defense’s claims concerning her mental state.
Juror No. 5 said the evidence never gave her the level of certainty she believed was necessary for a conviction.
‘There was not a single moment throughout that presentation of that case that you could say, ‘Oh yep, 100 percent I’m certain she did it,” she recalled. ‘There is too much gray area.’
The juror also offered a notable defense of the unidentified juror whose refusal to support an insanity acquittal ultimately prevented the panel from reaching unanimity.
Three other jurors who have spoken publicly reportedly expressed frustration with the holdout. But Juror No. 5 argued that the situation inside the jury room was more complicated than simply one person refusing to compromise.
‘This standalone juror was not the only one that was unwilling to see things from the other side, so I’m going to kind of defend that individual,’ she said.
She described the jury as a room filled with strong opinions and personalities.
‘There were some big personalities in that room, but at the end of the day, I feel like it just came down to an inability to move past your convictions.’
According to Juror No. 5, members of the panel began attempting to persuade the holdout relatively early in their deliberations. The disagreement reportedly became so heated that arguments could be heard outside the jury room.
Foreperson Roni Carlson and jurors Kellie Farina and Paula Devlin have separately discussed the deliberations and criticized the unidentified juror’s refusal to change his position.
Carlson said the jury at one point appeared close to reaching an agreement. That optimism faded when the holdout once again declined to support an insanity acquittal.
‘but I’m still not going to say she’s not guilty,’ Carlson recalled.
After more than a week of deliberations, Judge William Sullivan declared a mistrial on Sept. 4 when the jury remained unable to reach the unanimous verdict required to resolve the case.
Juror No. 5’s account now adds another layer to the extraordinary courtroom drama.
The final 11-1 split might suggest that the jury was almost uniformly convinced of one position from the beginning. Her comments show that was not necessarily the case.
At least one juror entered deliberations believing Clancy was guilty and criminally responsible, only to change her position after reviewing the evidence and considering the arguments surrounding Clancy’s mental state.
The revelation underscores just how difficult the case proved to be for the jury. The evidence surrounding the deaths was undeniably disturbing, but the central legal question ultimately turned on criminal responsibility and whether the prosecution had eliminated reasonable doubt.
For Juror No. 5, that doubt ultimately proved decisive.
For the prosecution, however, the mistrial means the legal battle surrounding the deaths of Cora, Dawson and Callan is not necessarily over. The extraordinary split among the jurors has ensured that questions surrounding Clancy’s mental state, criminal responsibility and the events inside the Duxbury home will continue to receive intense scrutiny.
