PLYMOUTH, Mass. — The murder trial of Lindsay Clancy could move more quickly than initially anticipated after the Duxbury mother personally addressed the court for the first time and agreed to stipulate to portions of the prosecution’s case.
Clancy’s decision allows prosecutors to avoid calling numerous witnesses to establish certain pieces of evidence, potentially shortening what had been expected to be a lengthy trial.
“Do you understand that there are certain facts that could be introduced during the course of the trial that would support, might support, the Commonwealth’s position regarding those elements? Do you understand that?”
“Yes, your honor,” Clancy said.
According to defense attorney Kevin Reddington, the agreement primarily covers technical evidence, including the chain of custody for blood and other biological samples, exercise bands, and DNA evidence.
“This stipulation basically relieves the government of having to bring in dozens, if not more, witnesses,” Reddington said.
More than 200 witnesses are on the potential witness list, and the stipulation could significantly reduce the number ultimately called to testify.
Clancy is accused of strangling her three young children with exercise bands in the basement of the family’s Duxbury home in January 2023 after allegedly sending her husband, Patrick Clancy, out on an errand.
She has pleaded not guilty to multiple murder charges.
The defense argues Clancy was suffering from postpartum psychosis at the time of the killings and is not criminally responsible. Prosecutors contend the killings were deliberate and planned.
The stipulation does not change Clancy’s plea or alter the charges she faces.
Wednesday’s proceedings are expected to end early, with the judge scheduled to address another matter involving both sides later in the afternoon.
Boston 25 News will continue to provide updates from inside the courtroom throughout the day.
