Mistrial Declared in Lindsay Clancy Murder Case After Jury Deadlocks for Third Time

Plymouth state court jurors spent more than 38 hours deliberating the case of Lindsay Clancy, the Massachusetts mother accused of killing her three young children, but ultimately reported they could not reach a unanimous verdict. The deadlock marks the third time the jury has declared itself unable to decide, leading the presiding judge to intend to declare a mistrial.

Clancy, 36, admitted to killing her children—Cora, 5; Dawson, 3; and Callan, 8 months—in January 2023. She survived a suicide attempt that resulted in paralysis from the waist down. Pleading not guilty by reason of insanity, she faces life imprisonment if convicted, though an acquittal could lead to indefinite hospitalization.

Closing arguments concluded last Thursday, ending a weeks-long trial that drew national scrutiny to postpartum mental health issues. The jury considered charges ranging from first-degree murder, punishable by life without parole, to second-degree murder and lesser manslaughter charges.

During deliberations, a jury note revealed a split of 11-1 in favor of acquittal. The lone holdout juror acknowledged having doubts but refused to apply them to the verdict. While the prosecution argued this indicated a disagreement on weighing evidence, the defense claimed the juror had lied under oath. The judge declined to remove or further question the juror.

The defense, led by attorney Kevin Reddington, argued that Clancy suffered from postpartum psychosis, a condition affecting approximately two per 1,000 births. They described her as a “darn good mother” who received inadequate medical care and was compelled by a persistent male voice during a psychotic episode. Prosecutors countered that Clancy acted “deliberately and meticulously,” asserting she was a “functioning mom” who understood right from wrong and demonstrated planning inconsistent with psychosis.

The formal declaration of mistrial has been temporarily suspended after the defense requested an emergency stay from Massachusetts’s highest court. The judge granted the defense one hour to file the appeal, leaving the outcome in limbo.
