Judge to Hear Defense Motions in Lindsay Clancy Post-Mistrial Hearing

Lindsay Clancy is set to return to a Plymouth courthouse on Tuesday, the first court appearance since a mistrial was declared in her murder case earlier this month. Judge William Sullivan will consider several motions filed by the defense, including a request to dismiss the case on double-jeopardy grounds and a petition to investigate a juror who allegedly failed to disclose prior involvement with the criminal legal system.

The mistrial was declared after the jury could not reach a unanimous verdict on first-degree murder charges related to the deaths of Clancy’s three children in their Duxbury home in 2023. While Clancy’s lawyers do not dispute that she strangled the children, they argue that postpartum mental-health issues should preclude criminal liability.

In a filing, defense attorney Kevin Reddington contended that eleven of the twelve jurors were prepared to find Clancy not criminally responsible, and that the court has an obligation to inquire when a juror does not fulfill his duty to apply the law as instructed. The double-jeopardy motion, described by Boston University emeritus law professor David Rossman as the most significant issue before the judge, could trigger appellate review regardless of the outcome.

Another motion seeks an investigation of the “holdout juror,” who retained counsel after reports that he may have omitted prior criminal-legal involvement on the juror questionnaire. Although such involvement would not automatically disqualify a juror, providing false information could result in a fine.

Legal analysts note that judges rarely investigate jurors and that Sullivan may be reluctant to grant the request without additional evidence. Retired judge Jack Lu warned that interfering with jury deliberations is unlikely to be favored by the court. Boston College law professor R. Michael Cassidy described the motions as a last-ditch effort and predicted that the judge will not rule on them during the hearing but will issue a decision shortly thereafter.

Prosecutors have not yet indicated whether they will pursue another trial on first-degree murder charges or consider lesser offenses such as second-degree murder or manslaughter, which would not require a jury trial. Cassidy suggested that the extensive legal issues raised by the post-trial motions could influence the district attorney’s strategy, potentially leading to a plea agreement that would keep Clancy in state-hospital care while avoiding a protracted retrial.
