Lindsay Clancy Trial Mistrial Spurs Motion to Probe Holdout Juror
By Drooid · · How we work
Core Event
On September 4, 2026 a Massachusetts judge declared a mistrial in Lindsay Clancy’s murder trial after the 12-person jury deadlocked 11-1. The lone holdout, Michael P. Desronvil, voted to convict on three counts of first-degree murder. The next day Clancy’s defense attorney, Kevin Reddington, filed a motion asking Judge William Sullivan to permit a “limited inquiry” into Desronvil’s juror questionnaire, cellphone use during deliberations, and any prior domestic-violence or eviction records. A hearing is set for September 29.
Background & Context
Clancy, 36, was charged with killing her three children—Cora, Dawson and infant Callan—in their Duxbury home in January 2023. She admitted the killings but claimed postpartum psychosis stripped her of criminal responsibility. Prosecutors argued she acted deliberately. The jury, nine women and three men, deliberated roughly 38 hours over seven days. Eleven jurors favored a not-guilty-by-reason-of-insanity verdict; Desronvil’s dissent prevented unanimity, prompting the mistrial.
Data & Statistics
- Jury composition: 9 women, 3 men
- Deliberation time: ~38 hours over seven days
- Holdout juror age: 48
Official Statements & Responses
Judge Sullivan has upheld an order shielding juror identities and questionnaire responses for safety. The Plymouth County district attorney’s office has not indicated whether it will seek a retrial. Reddington plans to request dismissal on double-jeopardy grounds at the September 29 hearing.
Criticism & Opposition
Legal commentators have questioned Desronvil’s conduct. Behavioral-law expert Mark Astor warned that exposing the jury’s “sacred arena” could undermine juror independence.
On-the-Ground Reports
Desronvil, through attorney Edward Paltzik, asserted his certainty of Clancy’s guilt:
> “I didn’t have any doubts… I kept getting cut off as if I had doubts based on the evidence present.”
He reiterated that the physical evidence and witness testimony proved Clancy’s intent.
Conflicting Reports & Gaps
Foreperson Roni Carlson told NBC 10 that Desronvil “admitted he had reasonable doubt,” a claim he denies. AP notes Desronvil faced a dismissed domestic-violence charge in 2021 and an eviction proceeding for over $12,000 in unpaid rent; US Magazine reports a civil restraining order from the same year. Whether these matters appeared on his questionnaire remains unknown.

What’s Next
The September 29 hearing will decide if the court will allow review of Desronvil’s questionnaire, cellphone metadata, and prior legal records. The decision will affect whether the state pursues a retrial, seeks a plea, or dismisses the charges under double jeopardy. The case remains unresolved, and debate continues over juror privacy and the use of postpartum mental-health defenses.
