For the first time since a mistrial was declared last week in the Lindsay Clancy murder case, three former jurors are speaking out, saying the panel was stopped from reaching a unanimous decision by a single holdout.
In interviews with NBC10 Boston, the jurors — among them the jury foreperson — said one member of the panel admitted there was reasonable doubt but still would not vote to find Clancy not guilty by reason of insanity.
The deadlock ended days of deliberations in the high-profile Massachusetts murder trial involving Clancy, a mother accused of killing her three young children in January 2023.
Clancy has acknowledged carrying out the killings, but her defense entered a plea of not guilty by reason of insanity, contending that she was in the grip of severe mental illness at the time. Prosecutors argued throughout the trial that she remained legally responsible for the children’s deaths.

“He admitted he had reasonable doubt and I started filling out the forms, I was so excited,” the foreperson told NBC10 Boston.
But the foreperson said the juror then added, “But I’m still not going to say that she’s not guilty by reason of insanity.”

The foreperson also told the station she wrote the note to the judge raising concerns that one juror had expressed reasonable doubt but would not agree to a verdict. The three jurors said they became frustrated with the holdout during deliberations, claiming he refused to consider the views of the rest of the panel.

NBC10 Boston reported it attempted to contact the juror identified by the others as the holdout but had not received a response.

A judge declared a mistrial last week after jurors informed the court they were hopelessly deadlocked following several days of deliberations.
It remains unclear whether prosecutors will seek to retry the case.
