Judge orders Lindsay Clancy jury to keep deliberating after deadlock on murder charges

Jury deadlock and judge instructions

On Tuesday, jurors in the Plymouth Superior Court murder trial of Lindsay Clancy reported that they were unable to reach a unanimous verdict after roughly 18 hours of deliberations across four days. Judge William Sullivan denied a mistrial declaration, instructing the panel of nine women and three men to return to the jury room and continue their discussions. The trial, which has run for five to six weeks, included testimony from over 80 witnesses and the introduction of more than 300 exhibits. Under Massachusetts law, criminal verdicts require the unanimous agreement of all 12 jurors.

I brought you back out because I know that this was a long trial. I know that there are over 80 witnesses, there are over 300 exhibits, but because of that, I'm going to ask you to go back out, keeping in mind all the instructions that I gave you, to go out and to continue your deliberations at this time.

Defense and prosecution arguments

Clancy, a 36-year-old former labor and delivery nurse, does not dispute that on January 24, 2023, she fatally strangled her three children, five-year-old Cora, three-year-old Dawson, and eight-month-old Callan, with exercise bands in the basement of their Massachusetts home. Defense attorney Kevin Reddington argued that Clancy was suffering from severe postpartum psychosis, a condition causing auditory hallucinations that commanded her to kill her children and herself. Clancy entered a plea of not guilty by reason of lack of criminal responsibility, pointing to months of psychiatric treatment and a hospital stay prior to the deaths.

Prosecutors led by Jennifer Sprague countered that Clancy acted with premeditation and clarity. The prosecution argued that Clancy sent her husband on errands to create an opportunity to carry out the killings before cutting herself and attempting suicide. Sprague described Clancy as calm, calculated, and fully conscious of the wrongfulness of her actions during the incident.

She lied, she stayed calm. She had total control over her emotions and behavior.

Evidence review and witness testimony

Deliberations began on Thursday afternoon following closing arguments. On Friday, the second day of discussions, jurors requested access to specific physical evidence, including medication bottles and a knife Clancy used before jumping from a second-story window. That fall left Clancy permanently paralyzed from the waist down, requiring her to use a wheelchair during court appearances.

The jury heard testimony from 85 witnesses, including medical professionals and Clancy's former husband, Patrick Clancy. Patrick Clancy, a sales director at Microsoft who discovered the children and founded a non-profit organization for maternal mental health, testified that his former wife's psychological condition worsened steadily following the May 2022 birth of their youngest child.

Potential verdicts and next legal steps

If deliberations remain deadlocked, Judge Sullivan will have to declare a mistrial, allowing prosecutors to retry the case before a new panel. If the jury reaches a consensus, Clancy faces several potential outcomes across three counts of first-degree murder and three counts of assault and battery. A conviction for first-degree murder carries a mandatory sentence of life imprisonment without parole. The jury may also consider second-degree murder, which permits parole eligibility, or manslaughter, which carries a maximum sentence of 20 years in prison. An acquittal based on a lack of criminal responsibility would result in Clancy being committed to a psychiatric facility if evaluations deem her a danger to the public.
