Lindsay Clancy Mistrial Declared After Jury Deadlocks 11-1, Massachusetts High Court Rejects Emergency Appeal

Since jurors entered their fifth day deadlocked on Wednesday, September 2, deliberations dragged two more days before collapsing entirely. Judge William Sullivan declared a mistrial Friday afternoon in the triple-murder case against Lindsay Clancy after jurors told him for a third time they could not reach a unanimous verdict, according to NPR and the Associated Press.

The jury's note read: "It is with a heavy heart that we report we are unable to come to a unanimous decision, and we will not be able to." Deliberations had stretched nearly 40 hours across seven days following a trial that ran more than six weeks, the Washington Post reported.

The Last-Minute Fight

Before Sullivan could formally end the case, defense attorney Kevin Reddington made an emergency play. He asked the Massachusetts Supreme Judicial Court to force Sullivan to remove a holdout juror Reddington argued was "biased" against people with mental illness, according to the Daily Wire. Sullivan gave Reddington one hour to file the appeal before bringing the jury back in, ZeroHedge reported.

Justice Dalila Argaez Wendlandt denied the emergency stay. Sullivan then formally declared the mistrial around 2 p.m.

Earlier in the day, Sullivan had already refused to dismiss the holdout juror, ruling that "the discharge of a deliberating juror is a sensitive undertaking, fraught with potential error," according to the Epoch Times. The juror hadn't refused to deliberate or shown any sign of illness or unwillingness to follow instructions, Sullivan said, so there was no legal basis to remove him.

That exchange got heated. When Reddington complained that Sullivan's reading of reasonable-doubt instructions was too "soft" and demanded he deliver it more "forcefully," Sullivan shot back, "What do you want me to do? Get a brass band?" according to The Hill.

What the Split Actually Means

Reddington told reporters the panel split 11-1 and blamed the holdout entirely, saying the juror "robbed" Clancy and the other jurors of "seven weeks" of their lives "for whatever his agenda was," per NPR and MS NOW. He predicted District Attorney Tim Cruz would lose a retrial and said Clancy "deserved an acquittal."

Nobody outside the jury room actually knows which way the 11 were leaning. The Guardian's live coverage explicitly flagged this, noting Reddington's claim that he'd "won" and "crushed" the prosecution's case is unverifiable since the direction of the split was never disclosed in court.

Cruz, for his part, pushed back hard on turning this into a referendum on maternal mental health. "This was, and has always been, about getting justice for those three little babies," he told reporters, according to NPR and the Guardian. He declined to say Friday whether his office will retry Clancy, negotiate a plea, or drop the case, though Sullivan indicated he'd like a retrial to happen this fall. A status hearing is set for September 29.

ZeroHedge's live blog cited a tweet claiming prosecutors had "ALREADY told the court they WILL be re-trying this case." This directly contradicts on-the-record statements from Cruz, reported by NPR, ABC News, and the Guardian, that no retrial decision had been made or would be announced Friday.

The Fair Fight Over What Happened

Clancy's defense never disputed that she strangled 5-year-old Cora, 3-year-old Dawson, and 8-month-old Callan with exercise bands in the family's Duxbury home on January 24, 2023, then attempted suicide by jumping from a second-story window, leaving her paralyzed. The argument was always about criminal responsibility, not the killings themselves.

Her lawyers argued severe postpartum psychosis left her unable to control her actions, backed by testimony from family members describing a rapid mental collapse after Callan's birth, according to MedPage Today. Prosecutors conceded she had serious mental illness but argued she planned the killings deliberately, pointing to testimony that she sent her then-husband Patrick out for medicine and dinner to clear the house first.

Supporters, including organized rallies outside the courthouse described by The Atlantic, have framed Clancy as a symbol of a healthcare system that fails mothers in crisis. The legal question a jury couldn't resolve was whether that illness rose to the level of eliminating criminal responsibility under Massachusetts law.

A Copycat Warning Sign

The case's reach beyond the courtroom turned dark this week. In Frankfort, Illinois, Corie Walsh, 40, was charged with murder after her 2-year-old son Barrett was found hanged in the family's basement, according to Fox News and the New York Post. Prosecutors say Walsh had been texting friends about the Clancy trial roughly three hours before her son was found dead, and told investigators she believed the boy was the "anti-Christ." Walsh remains hospitalized for self-inflicted, non-life-threatening wounds before transfer to the Will County jail.

No verdict was reached in the case that prompted that comparison. Clancy remains held at Tewksbury State Hospital under the original murder charges. Whether Plymouth County pursues a second trial, offers a plea, or walks away entirely will be decided before the September 29 hearing.
