Lindsay Clancy's murder trial ended in a mistrial after a single juror prevented the panel of 12 from reaching a unanimous verdict, prompting her defence lawyer, Kevin Reddington, to publicly criticise the holdout. Clancy, a former labour and delivery nurse, had admitted to strangling her three children at her Duxbury, Massachusetts home in January 2023 but pleaded not guilty by reason of insanity, citing postpartum psychosis. The case's collapse means the question of her guilt remains unresolved, with significant implications for how the justice system handles claims of severe mental illness in child homicide cases.

The jury, comprising nine women and three men, deliberated for almost 38 hours before informing Judge William Sullivan on Friday that they could not agree, marking the third time the panel had reported being deadlocked. Reddington made an unsuccessful emergency appeal to the Supreme Judicial Court, accusing the lone juror of bias against those with mental illness and asking that the individual be assessed or removed under the Americans with Disabilities Act. Several female jurors were seen crying as the mistrial was declared, while Judge Sullivan ordered that the jurors' identities remain sealed for at least 14 days. Reddington also criticised District Attorney Tim Cruz, describing him as "crushed" by the outcome.
