Former Psychiatric Hospital Employee Blocked From Testifying in Lindsay Clancy Trial After Explosive TikTok

A former psychiatric hospital employee who publicly accused prosecutors of “lies and misrepresentation” was questioned in court — but the jury was never allowed to hear her testimony.

Emily Thorndike, a licensed clinical social worker and former employee of McLean Hospital, became an unexpected figure in the Lindsay Clancy murder trial after posting a nearly 10-minute TikTok video criticizing prosecutors’ portrayal of the facility and the care Clancy received there.

The video quickly went viral, reportedly receiving more than 600,000 likes.

Thorndike claimed that certain aspects of McLean Hospital’s care were being misrepresented during the trial. Her comments caught the attention of Clancy’s defense attorney, Kevin Reddington, who later had a private investigator locate her and sought to add her to the defense witness list.

But when Thorndike appeared in court on Wednesday, Aug. 19, she never got the chance to address the jury.

Instead, she was questioned during a voir dire hearing conducted without the jurors present.

Reddington wanted Thorndike to testify about staffing levels at McLean, particularly during the holiday period when Clancy was treated there. The defense argued that her knowledge could provide context for the quality of care Clancy received.

At one point, Reddington made his position clear.

“I’m not looking to bring [Thorndike] in to disparage McLean Hospital,” he said. “They have done a good job of that themselves.”

Prosecutors strongly objected to Thorndike becoming a witness.

Their argument centered on a crucial fact: Thorndike had stopped working at McLean a year before Clancy was admitted to the facility. Prosecutors also pointed out that she had been following the trial before becoming involved as a potential witness.

That raised serious questions about how much firsthand knowledge she could actually provide regarding Clancy’s treatment.

Judge William Sullivan ultimately ruled that Thorndike would not be permitted to testify before the jury, saying her testimony had “limited value” because she was no longer working at McLean when Clancy was there.

The judge also noted that staffing information could be obtained from the hospital’s records rather than through Thorndike’s testimony.

The decision came as the defense continues building its argument that Clancy’s mental health treatment failed her in the months leading up to the January 2023 killings.

Clancy does not dispute that she killed her three children — Cora, 5, Dawson, 3, and Callan, 8 months old. Her defense maintains, however, that she was suffering from postpartum psychosis and was severely affected by psychiatric medications, making her not criminally responsible for the deaths.

In recent days, defense witnesses have offered several pieces of testimony supporting that theory.

Psychiatrist Dr. Donald Condie described some of Clancy’s medical records as “sparse” and questioned why certain blood tests were never performed.

Forensic psychologist Paul Zeizel testified that Clancy told her husband she had heard a male voice ordering her to kill her children and then herself.

Her former mother-in-law, Sue Clancy, also testified that Lindsay had been struggling significantly with her mental health and was “begging for help” before the killings.

Now, Thorndike’s testimony has been kept away from the jury.

And that leaves another unanswered question hanging over the trial:

What exactly was Emily Thorndike prepared to reveal about McLean Hospital — and could those details have changed how jurors view Lindsay Clancy’s final weeks before the killings?

The defense continues presenting its case as the trial moves into another critical phase.
