Holdout Juror Breaks Silence in Lindsay Clancy Mistrial

Breaking

The lone holdout juror who blocked a verdict in the Lindsay Clancy murder trial has broken his silence, directly disputing claims from his fellow jurors about what happened behind closed doors. Michael P. Desronvil, identified as the single juror who refused to find the former Duxbury, Massachusetts nurse not criminally responsible for killing her three children, said flatly, “I didn’t have any doubts.” He added, “As I tried to explain different possible theories during deliberation, I kept getting cut off as if I had doubts based on the evidence present.”

The jury deadlocked 11-1 after seven days of deliberation on September 4, with eleven jurors favoring a not-criminally-responsible verdict and Desronvil alone opposing it. Judge William Sullivan declared a mistrial after the panel said it could not reach a unanimous decision on whether Clancy understood the wrongfulness of killing 5-year-old Cora, 3-year-old Dawson, and 8-month-old Callan in January 2023.

Details & Background

Clancy, a former labor and delivery nurse, admitted to killing her three children but argued through her defense that severe postpartum mental illness left her not criminally responsible at the time. Massachusetts uses what’s known as the McHoul standard, which puts the burden on prosecutors to prove beyond a reasonable doubt that a defendant could appreciate the wrongfulness of their conduct or control their behavior. The defense called forensic psychiatrist Dr. Phillip Resnick, who testified Clancy “was unable to conform her conduct to the requirements of the law” due to postpartum psychosis and heard commanding voices ordering the killings. Prosecutors countered that she planned the killings, showed control by arranging for her husband’s absence that day, and was beyond the typical four-week postpartum window associated with the condition. Desronvil said that case persuaded him: “Based on all the physical evidence, key witnesses, and what the prosecution presents, I thought it was enough proof that she knew exactly what she was doing and planned.”

Fellow juror Paula Devlin gave a different account of the deliberations to CBS Mornings, saying the panel spent several days trying to bring Desronvil around to their view and describing the process as emotionally exhausting for jurors on both sides. Other jurors have claimed Desronvil at points acknowledged reasonable doubt before still refusing to back the insanity verdict, a characterization Desronvil rejects outright.

Reactions

Patrick Clancy, the children’s father and Lindsay’s former husband, addressed the mistrial through his attorney, David Meier, saying he was “grateful to the Court and to the jurors for their hard work, their commitment, and their perseverance.” He added that “the loss of Patrick’s children is something from which he will never recover and from which there will never be closure.”

Patrick Clancy also acknowledged how painful a retrial would be, saying “the prospect of reliving this tragedy through another trial is extraordinarily painful — for Patrick, for his family, and for all us.” His statement indicated he would not be commenting further for the time being.

Why This Matters to You

Plymouth County District Attorney Timothy Cruz has not yet announced whether prosecutors will seek a retrial, and the case returns to court on September 29 at Plymouth Superior Court for the next steps. Juror identities in the case are normally kept sealed for safety reasons, which makes Desronvil’s decision to publicly detail his side of the deliberations especially notable.

The dispute over what actually happened in the jury room underscores just how divided even sympathetic jurors were on one of the most emotionally difficult questions in criminal law: distinguishing genuine insanity from a defendant who understood exactly what she was doing. Whichever way Plymouth County prosecutors go next, the case is far from over for the Clancy family or the community that has followed it since 2023.
