The closely watched Lindsay Clancy trial ended in a mistrial after jurors reported that they could not reach a unanimous verdict following seven days of deliberations. The decision came after five weeks of testimony from 85 witnesses and the presentation of more than 300 exhibits in Plymouth County Court. Judge William Sullivan had indicated that he would declare a mistrial because Massachusetts does not permit a majority verdict in this type of case. Defense attorney Kevin Reddington made a last-minute effort to delay that decision, arguing that one holdout juror had failed to follow the court’s instructions and showed bias regarding serious mental illness. His emergency appeal was unsuccessful, and Sullivan formally discharged the jury while thanking its members for their commitment during the emotionally difficult proceedings.

Clancy faces charges connected to the January 2023 deaths of her three young children, Callan, Cora, and Dawson. Her defense does not dispute her involvement but maintains that she was experiencing postpartum psychosis and therefore should not be held criminally responsible. Prosecutors presented a sharply different account, arguing that her actions were deliberate and planned. The mistrial does not amount to either a conviction or an acquittal, leaving prosecutors to decide whether to pursue another trial, negotiate a different resolution, or take another legal step. The court scheduled a status hearing for September 29, when attorneys are expected to discuss how the case will proceed. Until then, the central dispute—whether Clancy’s mental condition prevented her from understanding or controlling her actions—remains unresolved.
