Judge Denies Lindsay Clancy Mistrial Request

The Lindsay Clancy mistrial request denied ruling on Aug. 24, 2026, did not simply reject the defense motion. In Plymouth Superior Court, Judge William Sullivan denied Kevin Reddington’s mistrial request, struck religion-focused rebuttal testimony, gave a curative instruction to the jury, reprimanded the prosecution, and kept the trial on its existing schedule, according to contemporaneous courtroom reports. [1][2]

Status matters here. This record is reported pending primary-order or docket verification; the available support is court-pool and news reporting, not a located written order. It is also an exceptional non-AI Risk Digest record and is not legal advice. Last checked: Aug. 26, 2026.

The exchange that triggered the motion

Dr. Kirk Heilbrun was on the stand as a prosecution rebuttal witness when the religion issue returned to the jury. His broader role was to challenge the defense’s mental-state theory: reports described him as testifying that Clancy was criminally responsible on Jan. 24, that a claimed one-time command hallucination would be “very, very unusual,” and that the case fit his view of “altruistic filicide.” [1][3]

The mistrial request arose from a narrower part of that testimony. Heilbrun raised Clancy’s Catholic faith in rebuttal, and testimony referencing suicide as a “mortal sin” reached the jury. Reports also described testimony about Clancy saying, “Go to God, baby. Go to God,” though NBC’s live blog used the formulation “go with God.” This record does not smooth over that wording difference; the sources agree on the procedural point that religion-focused testimony reached the panel and drew an immediate defense challenge. [1][3][5]

That distinction is the reason the ruling should not be read as a broad finding about faith evidence, Catholic doctrine, or juror psychology. The live issue was what the jury heard, whether the prosecution had caused a forbidden theme to recur, and whether a strike-and-instruction response could cure the problem without restarting the trial.

Why the Aug. 18 episode mattered

The Aug. 24 objection did not land on a clean slate. On Aug. 18, during testimony from former mother-in-law Susan Clancy, the prosecution had asked about murder as a “mortal sin.” Judge Sullivan stopped that line of questioning, struck it, and addressed the matter at sidebar, according to reporting on the earlier exchange. [4]

That prior strike supplied the comparator for Reddington’s mistrial argument. He argued that the prosecution had brought “the same thing again” before the jury, characterized it as “intentional misconduct on the part of the prosecution,” and objected to “injecting Roman Catholic faith into this trial.” [2]

The prosecution’s reported response was narrower: the testimony was unintentional, and the prosecutor had not asked Heilbrun religion-focused questions that called for that answer. [1][2]

Denial plus repair, not denial alone

Sullivan denied the mistrial request, but he did not leave the testimony sitting in the case as ordinary evidence. He told jurors: “The religion that the defendant was raised is absolutely an inappropriate area of testimony. It is to be stricken. It is not to be considered.” Reports also described him instructing that the testimony was “immaterial, irrelevant and to be disregarded.” [2][3]

He also reprimanded the prosecution and directed prosecutors to speak with Heilbrun about his conduct. [2]

That combination is the ruling. A denied mistrial motion is not the same thing as a judicial blessing of the testimony. Here, the judge treated the challenged religion material as inappropriate and removed it from the jury’s consideration, while declining the defense’s requested remedy of ending the trial and starting over.

For trial coverage, this is where careless shorthand does damage. “Mistrial denied” answers only one part of the procedural event. The equally important parts are that the testimony was struck, the jury was told not to consider it, and the prosecution was rebuked for allowing the issue to recur.

What the ruling did not decide

The Aug. 24 ruling did not decide guilt, criminal responsibility, psychosis, or appellate outcome. Heilbrun’s rebuttal opinions remained part of the prosecution’s answer to the defense mental-state case, but the mistrial ruling itself was about trial management after an objectionable subject reached the jury.

Readers tracking the broader defense theory can separate this ruling record from the doctrinal questions covered in How the insanity defense works in Lindsay Clancy’s trial and What is the psychosis defense in the Lindsay Clancy trial? The concession posture of the trial is treated separately in Inside the Clancy trial’s concession strategy.

Where the case stood afterward

The trial did not reset after the Aug. 24 ruling. Rebuttal testimony concluded on Aug. 25, closing arguments were expected on Thursday, Aug. 27, and deliberations were possible on Aug. 28, according to later trial timeline reports. [5]

As of Aug. 26, 2026, available reports showed no verdict. The next procedural checkpoint is closing argument, addressed separately in What the Lindsay Clancy closing arguments come down to. For the limits of verdict prediction in this case, see Can Anyone Predict the Lindsay Clancy Verdict?.

The mistrial posture also should not be confused with a hung-jury mistrial. A denied midtrial motion based on alleged trial error is a different procedural event from a jury later being unable to agree, the contrast discussed in the Johnson County Sheriff Adam King Retaliation Case Status record.

The appeal boundary remains conditional. Reddington told reporters that Sullivan “gave a forceful instruction and we under the law assume the jurors listened,” and that an appeal over the issue would first require a conviction. [5]

That is the procedural posture left by the Aug. 24 ruling: no mistrial, no verdict signal, challenged testimony struck, jury instructed, prosecution reprimanded, and any appellate fight deferred unless there is a conviction to appeal from.
