Lindsay Clancy defense wants TikToker to expose hospital ‘lies’ as judge warns ‘this is not Tripadvisor’

A dispute rooted in a TikTok video arose at the outset of Lindsay Clancy's murder trial Tuesday, as her attorneys moved to add a former mental hospital staff member to the witness list — one who had publicly accused witnesses of spreading "lies and misrepresentations" about the psychiatric facility where Clancy was treated weeks before she killed her three children.

Defense attorney Kevin Reddington asked Judge William Sullivan to add former McLean clinical social worker Emily Thorndike to the witness list, arguing that her years working on the same short-term unit could rebut what he described as a misleading picture of a "five star" hospital overflowing with treatment options that Clancy refused.

"Her involvement in this case came about after one of the prosecutors — I don't recall which — made it out on direct examination that McLean is some kind of a five-star institution where the doctors, the psychiatrists, the psychotherapists, and the counselors were all banging into each other in the hallway trying to interview Miss Clancy, who was just blithely refusing care and treatment, which is not the case," Reddington said.

"So now the jury is left with that image that McLean is purportedly some kind of a five-star hospital because they are affiliated, quote-unquote, with Harvard," he continued.

Reddington explained that he tracked down the TikToker, later identified as Thorndike, after she took to the social media platform to expose the level of treatment at the mental health facility.

"I saw her video saying that she could not stand for, and I quote, ‘the lies and the misrepresentations from that witness stand about McLean Hospital’."

Prosecutors, meanwhile, fired back that Thorndike had left McLean roughly a year before Clancy’s stay, had no firsthand knowledge of her treatment and had been following the trial online before posting her opinions online.

"This is not Tripadvisor," the judge quipped, saying he would not permit a battle over whether McLean deserved five stars or two.

But Sullivan called the narrower question of staffing and available programs a "closer call" and took the defense motion under advisement. He has not ruled about whether or not to allow Thorndike to take the witness stand.

The witness list dispute came before jurors heard a series of desperate messages Clancy sent to her psychiatric nurse practitioner, Rebecca Jollotta, in late 2022 as she struggled with insomnia, medication changes and intrusive thoughts.

Jollotta testified Tuesday that she interpreted the message as symptoms of depression and anhedonia, the inability to experience pleasure, rather than suicidal ideation, and did not direct Clancy to immediately go to an emergency room.
