Fact card

Item	Status	What is established
Verdict	VERIFIED	No verdict was returned. A mistrial was declared September 4; no conviction or acquittal was entered.
Pending charges	VERIFIED	Three counts of first-degree murder.
Removed counts	VERIFIED	Prosecutors filed a nolle prosequi on July 9 for three separate strangulation counts, describing them as redundant because the alleged conduct was subsumed within the murder charges. That filing reduced the count total; it was not an exoneration on the remaining charges.
Plea	VERIFIED	Not guilty.
Trial posture	VERIFIED	The trial ended September 4 in a mistrial after the jury could not agree. The three murder charges remain pending.
Court and judge	VERIFIED	Plymouth Superior Court; Judge William F. Sullivan.
Next scheduled step	SEE CURRENT UPDATE	The procedural update below supersedes the historical September 29 appointment.
Hearing time	NOT PUBLICLY VERIFIED	The next reported hearing has no independently verified start time in this tracker.
Renewed acquittal request	REPORTED RULING	See the October 1 update below; the charges remain unresolved.
Retrial decision	SEE CURRENT UPDATE	Do not confuse a motions hearing with a retrial.
Defense counsel	VERIFIED	Kevin Reddington.
Core defense	DEFENSE	Lack of criminal responsibility, tied to the defense’s contention that Clancy experienced postpartum psychosis and that alleged overmedication affected her condition.
Burden on criminal responsibility	VERIFIED	Once evidence fairly raises lack of criminal responsibility, Massachusetts law requires the Commonwealth to prove beyond a reasonable doubt that the defendant was criminally responsible.

What the trial asked the jury to decide

The criminal trial was not a general referendum on postpartum mental illness. It concerned specific charges, evidence, and legal instructions.

PROSECUTION: Prosecutors argue that Clancy committed the charged acts deliberately and was criminally responsible at the time.

DEFENSE: The defense argues that she experienced postpartum psychosis and lacked criminal responsibility under Massachusetts law. It also alleges that prescribing and medication-management failures contributed to her condition. Those medication allegations appear in attorney statements and civil litigation; they are not established criminal-case facts.

Under the Massachusetts standard associated with Commonwealth v. McHoul, a defendant lacks criminal responsibility if, because of a mental disease or defect, the person lacked substantial capacity either to appreciate the wrongfulness of the conduct or to conform the conduct to the law. When the issue is properly raised, the Commonwealth bears the burden of proving criminal responsibility beyond a reasonable doubt.

A clinical diagnosis and a legal finding are not the same thing. Experts may address diagnosis and symptoms; jurors apply the judge’s legal instructions to all admitted evidence.

Key pretrial rulings

VERIFIED — Emergency call admitted: The judge ruled that jurors could hear the 911 recording. Pretrial reporting described planned limiting guidance on how jurors could use it. This page describes the ruling in text only.
VERIFIED — Lay postpartum-psychosis testimony blocked: The judge barred proposed lay witnesses from describing their own experiences as a way to explain postpartum psychosis to jurors. Qualified experts may still address clinical issues within the evidentiary rules.
VERIFIED — Autopsy photographs admitted: The judge allowed prosecutors to use autopsy photographs. This tracker does not reproduce or describe the images.
VERIFIED — Home view allowed: The court approved a jury view of the home, subject to trial logistics and judicial directions.
VERIFIED — Sequestration denied: The judge declined to sequester the jury. Jurors were required to follow the court’s instructions about avoiding outside information.

Where the case stands now

Judge William Sullivan declared a mistrial on September 4 after the jury reported that it could not reach a unanimous verdict. The trial ended without a conviction or acquittal. Clancy remains charged with three counts of first-degree murder, has pleaded not guilty, and remains presumed innocent.

October 1 ruling — checked October 2

AP reports that Judge Sullivan denied the renewed request for a required finding of not guilty. This is an evidence-sufficiency ruling, not a verdict. The charges remain unresolved.

September 29 procedural update — historical

AP’s hearing report describes the defense renewing its acquittal argument. The judge reserved a decision; prosecutors remained undecided about retrying the case.

The Globe reports further motions on November 2.

The Court Calendar carries the reported setting and verification limits. This tracker has not obtained a primary order or independently confirmed the clock time.

The mistrial did not decide the contested criminal-responsibility question. Competing psychiatric opinions remain testimony offered by the parties, not findings that establish either side’s account.

Claim-status ledger

This ledger is for editors and readers who encounter assertions circulating around the case. Inclusion here does not elevate a claim into fact.

Claim	Label	Publishable treatment
The 911 recording includes Patrick Clancy saying the children were harmed.	VERIFIED	A short, attributed description of the admitted recording is supportable. The caller’s statement reflects what he said in an emergency; it is not a verdict and does not by itself decide guilt or criminal responsibility.
Clancy had been prescribed a large number of medications.	REPORTED-NOT-CONFIRMED / NOT-ADJUDICATED	Defense attorney Kevin Reddington made a medication-count claim in public comments. It is attributed to the defense and is not stated as a medical-record finding unless the underlying records are admitted and authenticated.
Clancy sought help repeatedly.	REPORTED-NOT-CONFIRMED / NOT-ADJUDICATED	Civil filings and reporting describe repeated help-seeking, but a precise total has not been established in the criminal trial.
Clancy heard a “male voice.”	REPORTED-NOT-CONFIRMED / NOT-ADJUDICATED	A civil complaint alleges an auditory command described as a male voice. It is attributed to the civil pleading or defense and is not presented as an adjudicated fact.
Mothers with postpartum-psychosis experiences contacted the defense.	NOT-VERIFIED	An attorney said women had contacted the defense, but the contacts and their accounts are not independently verified. Excluded from the article body.

Questions readers are asking

Has there been a verdict?

No verdict was returned. Judge Sullivan declared a mistrial September 4 after the jury could not agree. No conviction or acquittal was entered, and Clancy remains presumed innocent.

What charges does Lindsay Clancy face?

She faces three counts of first-degree murder and has pleaded not guilty. Prosecutors’ July 9 nolle prosequi removed three additional method-specific counts as legally redundant; it did not dispose of the murder charges.

What does “lack of criminal responsibility” mean in Massachusetts?

It is a legal standard, not a medical diagnosis. In general terms, the question is whether, because of a mental disease or defect, a defendant lacked substantial capacity to appreciate the wrongfulness of the conduct or to conform the conduct to law. The judge gives the controlling instructions, and the Commonwealth must prove criminal responsibility beyond a reasonable doubt once the issue is properly raised.

Is the defense arguing postpartum psychosis?

Yes. DEFENSE: Clancy’s lawyers argue that she experienced postpartum psychosis and lacked criminal responsibility. They also allege that overmedication played a role. PROSECUTION: Prosecutors dispute the defense’s account and contend the evidence showed deliberate, criminally responsible conduct. Neither position is a jury finding.

Does postpartum psychosis mean someone is violent?

No. Postpartum psychosis is a rare, serious, treatable medical emergency that requires immediate professional care. A diagnosis does not establish that a person is violent, and it does not answer the legal question of criminal responsibility in any individual case.

Who has the burden of proof?

The prosecution must prove every element of the charged offenses beyond a reasonable doubt. Once lack of criminal responsibility is fairly raised, the Commonwealth also bears the burden of proving criminal responsibility beyond a reasonable doubt.

Would an acquittal based on lack of criminal responsibility mean immediate release?

Not automatically. Massachusetts law allows the court to order hospitalization for observation and examination after such an acquittal. A separate commitment process can follow, and continued commitment requires the statutory findings.

What was the ruling on the 911 call?

The judge allowed the recording for the trial that ended in a mistrial. This tracker does not autoplay the recording or reproduce an extended transcript.

What happens next?

See the October 1 update above and the reported November 2 setting in the Court Calendar. A motions hearing does not establish a retrial date; the clock time remains unverified.

Update log

These dated entries record what was known at each cutoff; earlier trial-stage descriptions are historical.

October 2, 2026 — Ruling and current-status correction

Updated the current-status sections and linked source; earlier entries retain their dated cutoffs.

September 29, 2026 — Procedural update at that cutoff

Refreshed the current-status sections from the linked hearing reports; older entries below remain historical.

September 11, 2026 — September 29 setting confirmed; renewed Rule 25(b)(2) motion filed and pending

VERIFIED: The next courtroom date is a status conference and trial-assignment proceeding on September 29, 2026, in Plymouth Superior Court, set from the bench when the mistrial was declared and reported for 9 a.m. Eastern. FILED, NOT RULED: On September 10, defense counsel filed a renewed motion for a required finding of not guilty under Rule 25(b)(2), seeking a finding of not guilty by reason of lack of criminal responsibility on each indictment, and asked that it be heard September 29. No ruling has issued. Prosecutors have not announced a retrial decision, and no retrial date exists. The earlier September 28 report is not corroborated and is not used here.

September 9, 2026 — Mistrial recorded in this tracker

VERIFIED: The September 4 mistrial ended the trial without a verdict. Three first-degree murder charges remain pending, and Clancy remains presumed innocent. A mistrial is not a verdict, a conviction, or an acquittal.

September 2, 2026 — Fifth day of deliberations; jurors questioned

VERIFIED: Judge Sullivan questioned jurors and alternates individually after a woman was accused of filming jurors outside the courthouse. Jurors resumed deliberations at about 9:30 a.m. At that September 2 cutoff, no verdict or mistrial had been announced. The separate filming allegation remains unproven unless adjudicated.

September 1, 2026 — Jury reports an impasse

VERIFIED: Jurors told the judge they were unable to reach a unanimous decision after many hours of deliberation. Judge Sullivan instructed them to continue. Court ended for the day without a verdict; the note did not itself create a mistrial.

August 24, 2026 — Court adjourned with rebuttal unfinished

VERIFIED: Dr. Avram Mack’s testimony concluded. Dr. Kirk Heilbrun had not finished when court adjourned, and one further Commonwealth rebuttal witness was expected. Judge Sullivan denied a defense mistrial request, directed jurors to disregard the challenged religion-related testimony, and excused the jury until Tuesday morning. No verdict has been returned, the jury has not begun deliberations, and any August 25 closing-argument setting remains tentative with no publicly verified time.

August 23, 2026 — Defense rested; prosecution rebuttal underway

VERIFIED: The defense rested August 21 after Dr. Phillip Resnick’s testimony. Prosecutors began their rebuttal case with testimony from Dr. Avram Mack. No verdict has been returned. Testimony is expected to continue August 24, and Judge Sullivan said closing arguments would likely be held August 25; that schedule remains subject to change.

August 17, 2026 — Prosecution rested

VERIFIED: The Commonwealth rested its main case. The defense then began presenting witnesses concerning Clancy’s mental state, treatment history, and its contention that she lacked criminal responsibility.

July 27, 2026 — Opening statements began

VERIFIED: The evidentiary trial began after jury selection. The prosecution and defense presented competing accounts; opening statements are not evidence.

July 15, 2026 — No verdict; trial start remains scheduled

VERIFIED: No verdict. The most recent reliable pretrial reporting continues to list jury selection for July 20 in Plymouth Superior Court before Judge Sullivan.

July 13, 2026 — Final pretrial rulings and jury plan

VERIFIED: The judge blocked the proposed lay postpartum-psychosis witnesses, denied sequestration, and described a plan to seat 18 people, including six alternates.

July 9, 2026 — Count total reduced

VERIFIED: Prosecutors entered a nolle prosequi on three redundant counts. Three first-degree murder charges remain pending.

June 2026 — Evidence rulings

VERIFIED: The court allowed the 911 recording, autopsy photographs, and a jury view of the home. The existence of a ruling does not establish the truth of either side’s interpretation of the evidence.

Reader note

Court schedules and evidentiary plans can change. This tracker distinguishes what happened in court from what either side says the evidence means. Corrections identify the changed fact, the source, and the time of the update.
