Lindsay Clancy Murder Trial: Post-Mistrial Motions and the Double-Jeopardy Debate

01
Core Event – Post-Mistrial Motions
Following the mistrial, both prosecution and defense have filed competing motions in Plymouth Superior Court. Prosecutors, led by Assistant District Attorney Jennifer Sprague, ask the judge to reject Clancy’s motion to dismiss the murder indictments on double-jeopardy grounds and to uphold a gag order limiting public commentary. Clancy’s counsel, headed by Kevin Reddington and Martin G. Weinberg, argue the mistrial was improper because the judge did not sufficiently investigate a holdout juror’s alleged refusal to apply reasonable-doubt standards, and that a new trial would violate double-jeopardy protections. The court will consider these motions at a hearing on November 2.

Background & Context
In January 2023, three children—Cora, Dawson and Callan (8 months)—were found dead in their Duxbury, Massachusetts home. Clancy, a former labor-and-delivery nurse, was indicted on three counts of first-degree murder and three counts of strangulation. Her defense asserted postpartum psychosis as a mitigating factor. After a six-week trial, jurors were deadlocked; eleven jurors favored acquittal by reason of insanity while one juror, Michael Desronvil, maintained a guilty stance. Judge William Sullivan declared a mistrial on September 4.

Official Statements & Responses
The filing cites the *Karen Read* precedent, noting the Supreme Judicial Court’s rejection of post-trial juror revelations as a basis to block a second prosecution.
The defense contends that a more thorough inquiry—such as directly questioning the foreperson about the holdout juror—could have avoided the mistrial, making a subsequent trial a double-jeopardy violation. Regarding the gag-order request, Reddington and co-counsel Laura B. McConnell describe it as “prior restraint” that would suppress speech without evidence and protect “a jury that doesn’t exist.”

Verbatim Quotes
- “After many hours of deliberation, we are unable to come to a unanimous verdict.” — Judge William Sullivan
- “Based on all the physical evidence, key witnesses, and what the prosecution presented, I thought it was enough proof that she (Clancy) knew exactly what she was doing and planned,” — Michael Desronvil
- “The government asks the court to restrain counsel’s speech without evidence, to protect a jury that doesn’t exist, a trial that has not even been scheduled, under an order that singles out one side’s speech about discharged jurors,” — Laura B. McConnell

What’s Next
The court will hear arguments on both the double-jeopardy dismissal motion and the gag-order request on November 2. A decision will determine whether Clancy faces a retrial or if the criminal case ends after the mistrial.
