The documentary record in this case is much thinner than the video record. Massachusetts does not publish criminal filings online, and the great majority of what was filed in Commonwealth v. Clancy has never been posted anywhere. What follows is what is genuinely available.
These are the Commonwealth's own contemporaneous announcements, and the closest thing to an official public record of the charging decisions.
Unsealed in October 2023, these are the warrants, supporting affidavits and evidence returns from the search of the Duxbury home. They are the single most substantial primary document in the case and the source of most of what was reported about the investigation.
On the final day of deliberations, with the judge preparing to declare a mistrial, the defense petitioned the Supreme Judicial Court to intervene — asking that the trial court either question the holdout juror about their ability to follow the law on reasonable doubt, or remove that juror. The petition argued the juror's reasoning reflected bias against people with severe mental illness. The court denied it that afternoon, and the mistrial followed.
On July 20, 2026, Patrick Clancy — the father of Cora, Dawson and Callan, and the personal representative of their estates — asked the court to restrict the public display of certain evidence at trial: the audio of the 911 call he placed, all photographs of his children including crime scene and autopsy photographs, and their clothing. He did not ask to close the courtroom or to withhold anything from either side's lawyers. The motion was brought under the Massachusetts Victim's Bill of Rights and argued that public dissemination would cause lasting harm to his family and disrespect the dignity and memory of the children.
On July 24, 2026 the court granted the request in part. Media and members of the public in the courtroom were barred from recording, displaying or reproducing the audio of the 911 call and the autopsy photographs. Reporting on their contents remained permitted, and jurors, witnesses and both trial teams retained full access.
The standard the jury was asked to apply is set out in the Massachusetts model jury instruction on lack of criminal responsibility, published by the Trial Court. It is the clearest available statement of the question that decided this case, including the allocation of the burden of proof to the Commonwealth.
The following were filed and ruled on, and none of them are available online:
The grand jury indictment of September 15, 2023.
The defense motion for a bifurcated trial, the Commonwealth's opposition, and the ruling of March 31, 2026.
The motions and rulings concerning The New Yorker's recordings and Lindsay Clancy's psychiatric records.
The motion for a mistrial argued on August 24, 2026 and the judge's denial
The expert reports of the psychiatrists and psychologists who testified, which in Massachusetts practice are ordinarily not filed publicly at all.
Getting them would mean going to the courthouse. The Massachusetts Trial Court's public portal at masscourts.org will show docket entries, but criminal cases cannot be searched by name online (only civil ones can) so the case number has to be obtained first. Document images for Superior Court criminal matters are generally not available remotely in any event. Hard copies require an in-person visit to the Clerk's office at Plymouth County Superior Court in Brockton, with copying fees set by the Clerk. Questions about the portal go to eAccess@jud.state.ma.us.
If you have obtained any of these filings and are willing to share them, please get in touch.
