Judge Bars TikTok Witness in Lindsay Clancy Trial, Cites Weak Value

A Plymouth Superior Court judge on Wednesday blocked Lindsay Clancy's defense team from calling a former McLean Hospital employee as a witness, ruling that her testimony carried limited value to the case even after finding her credible. The employee, Emily Thorndike, had come to the defense's attention only after she posted a TikTok about the high-profile murder trial, prompting defense attorney Kevin Reddington to send an investigator to track her down.

Judge William Sullivan made the ruling following a voir dire held outside the presence of the jury, according to WCVB. Sullivan determined Thorndike was credible but found her account had limited materiality to the trial, which centers on whether Clancy, 36, was criminally responsible when she strangled her three children, Cora, Dawson and Callan, inside the family's Duxbury home in January 2023. Clancy has pleaded not guilty and is being held at Tewksbury State Hospital; she jumped from a second-floor window after the killings and was left partially paralyzed.

What the TikTok Witness Would Have Said

Thorndike, who worked at McLean Hospital until leaving in December 2021, testified during the closed-door hearing that patient visits at the facility could sometimes last about one minute and that it would be misleading to characterize those visits as in-depth. She also said there was minimal family contact until the treatment team became available during the week, and that only one doctor covered the facility on holidays and weekends, per the same WCVB report. Thorndike told the court she grew emotional listening to earlier trial testimony because what she heard did not align with her own experience working at McLean.

The defense argued jurors had been left with an overly favorable impression of McLean Hospital, the psychiatric facility affiliated with Harvard Medical School where Clancy was admitted for inpatient care starting New Year's Day 2023, weeks before the killings, according to CBS News. Prosecutor Shanan Buckingham challenged how much Thorndike actually knew about conditions at the hospital during the specific window when Clancy was hospitalized, given the gap since her own departure. Sullivan ultimately allowed staffing records from McLean describing conditions during Clancy's treatment period into evidence instead, a middle path that let jurors weigh documented staffing levels without speculative outside testimony.

Inside the Broader Case Against Clancy

The dispute over Thorndike's testimony came on the same day the judge dismissed jurors early due to unforeseen circumstances, shortly after completing voir dire on the potential witness and wrapping up cross-examination of defense expert Dr. Paul Zeizel, per CBS News. Zeizel, a clinical and forensic psychologist who met with Clancy 45 times after her hospitalization, testified a day earlier that Clancy reported hearing a male voice instructing her to kill her children and die by suicide, and said psychological testing led him to conclude she was not faking her symptoms.

Prosecutors rested their case on August 17 after calling 72 witnesses over nearly four weeks of testimony, the station's coverage notes. Susan Clancy, Lindsay's former mother-in-law and a fellow labor and delivery nurse, testified that Lindsay was “begging for help” and had sent text messages expressing terror over her reliance on prescribed medications in the months before the killings, according to the Associated Press. Earlier in the trial, which began July 20, jurors visited the Clancy family's Summer Street home in Duxbury, where the strangulations occurred, the wire service reported.

The Legal Standard at the Heart of the Trial

Clancy's defense does not dispute that she killed her children; the central question for the jury of 12 women and six men is whether she was criminally responsible at the time. Under the Massachusetts standard set in Commonwealth v. McHoul, once a defendant presents evidence of mental incapacity, the burden shifts entirely to prosecutors to prove beyond a reasonable doubt that she retained the capacity to appreciate the wrongfulness of her conduct, according to Nolo. Clinical research published in the American Journal of Psychiatry found that while first-onset postpartum psychosis is rare, affecting an estimated 0.25 to 0.6 per 1,000 births, a woman's relative risk of a first psychotic episode is 23 times higher in the month after childbirth than at any other point in her life.

Once jurors finish hearing the case, they will learn which of them will deliberate and which will serve as alternates. The trial has drawn comparisons to another Massachusetts case, after the state's Supreme Judicial Court granted a new trial this year to Latarsha Sanders, a mother convicted of killing her sons who also claimed severe mental illness; legal analysts have pointed to that ruling as a signal of how state courts may weigh postpartum psychiatric breaks under the same McHoul standard, as Hoodline previously reported.

Parallel Civil Suits Over Her Care

Separate from the criminal case, Clancy filed a medical malpractice lawsuit in January in Norfolk County Superior Court, represented by attorney Rosemary Scapicchio, against McLean Hospital, South Shore Health System, Women & Infants Hospital and individual providers. The suit alleges a catastrophic failure by multiple medical providers to diagnose and treat her psychiatric condition. Her former husband, Patrick Clancy, filed a related wrongful death suit against medical professionals who treated her, a case Hoodline detailed in its report on the wrongful death filing. Those civil cases remain pending as the criminal trial continues in Plymouth Superior Court.
