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.WATCH: Defense seeks to add former McLean Hospital employee to witness list in Lindsay Clancy caseLINDSAY CLANCY’S HUSBAND COULD TESTIFY FOR HER AT TRIAL OVER DEATHS OF THEIR THREE CHILDREN"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.Clancy is charged with first-degree murder in the deaths of her three children, 5-year-old Cora, 3-year-old Dawson, and 8-month-old Callan.(Greg Derr/Pool/The Patriot Ledger)LINDSAY CLANCY’S EX-HUSBAND DETAILS PILL USE AS EXPERT SAYS EVIDENCE COULD SHAPE MURDER TRIALReddington 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 tha...
