Jurors in the Lindsay Clancy trial have made their first public remarks about the secretive deliberations and what led to their deadlock before the high-profile case ended in a mistrial.
Three female jurors - including the foreperson - told NBC the panel was ready to enter a verdict that Clancy was not guilty by way of insanity in the murder of her three children, but one juror would not agree.
The foreperson said the male juror "admitted he had reasonable doubt" in her criminal responsibility but wouldn't agree to a not guilty verdict.
Clancy has not denied the killings but her attorneys argued she had been suffering from postpartum psychosis. Prosecutors argued she made a calculated decision.
The identities of the nine women and three men on the jury have not been made public and the judge banned any photographing or filming of them during the trial to retain their anonymity.
But in the US, once a case is over, any juror can choose whether or not to speak publicly about a case and their deliberations. Jurors often choose to speak out - some even write books - after high-profile cases like that of Clancy.
The BBC, which was in the court during the case, has confirmed the three women who spoke with NBC were on the jury panel.
In the NBC interview, which aired on Tuesday, the jury foreperson - a retired fifth-grade teacher - called not being able to reach a verdict in the case "awful" and an "emotional roller coaster". A foreperson acts as a spokesperson for a jury in any US legal case, meaning they are the person delivering a verdict and sending notes to the judge on behalf of the 12-person panel.
She said the deliberations were difficult and filled with "lots of crying" and "lots of tears and then hugging".
"I was so sad, so sad that we couldn't come up with a verdict for Lindsay. It was so heartbreaking," she added.
Throughout the interview, the three women said the jury was in nearly unanimous agreement to enter their verdict but the holdout juror would not change his mind.
The foreperson said the lone juror "admitted he had reasonable doubt and I started filling out the forms, I was so excited".
She was halfway through filling out the verdict sheets when the holdout juror, who she said was a man, continued: "But I'm still not going to say that she's not guilty by reason of insanity," she says he told the panel.
The man in question has not come forward and has not responded to these comments.
The three jurors noted their deliberations led to fights and yelling, which at times could be heard through the walls.
Under Massachusetts law, there was no burden on Clancy to prove her mental illness and that she lacked criminal responsibility. Rather, it was on the prosecution to prove beyond reasonable doubt she was criminally responsible when she killed her children, criminal defence lawyer Elyse Hershon previously told the BBC.
"We weren't trying to figure out if she murdered the children. She did and she's admitted that," the foreperson explained in the interview with NBC. "We're trying to figure out - did she know right from wrong at that time."
The three jurors noted they didn't feel persuaded by the prosecution.
"Everything proved that she loved her children so she had to have snapped and not known what she was doing," the foreperson said.
Another juror, who does work for a government defence contractor, said the holdout juror had questions about what medication Clancy was on.
"We had the toxicology reports. We could see exactly the amounts," she said, adding that there were nurses on the jury who spoke about that. "He just completely disregarded the information that they gave," the juror added.
The third juror, a chef at a senior centre, said she found the prosecutors in the case to be "very, very harsh", adding: "They had no character witness in regard to Lindsay of being a bad mother."
