Baby-faced Ivy-league psychiatrist who'd never met Lindsay Clancy but prescribed her barrage of drugs takes center stage in children's horror murder trial

The baby-faced psychiatrist who prescribed a boatload of drugs to Lindsay Clancy without ever meeting her in person has become a key figure in 'America's saddest murder trial.' 

Dr. Jennifer Tufts's frustrated, impolite demeanor towards Clancy's lawyer, her bumbling answers, and her apparent unpreparedness for her time on the stand have made her a key talking point during the triple filicide trial. 

Tufts, 37, was called as an 'expert witness' by the prosecution on Friday and faced a fiery grilling from Kevin Reddington, Clancy's defense attorney, on Monday. 

The Cornell University graduate confessed to treating Clancy and prescribing the 35-year-old mother multiple different medications in the four months leading up to the deaths of her children. 

She also openly admitted that she only met Clancy on telehealth medicine, or video chat calls, and that she increased her medication just one day before Cora, five, Dawson, three, and eight-month-old Callan were strangled to death with exercise bands in January 2023. 

The former labor and delivery nurse harmed herself before jumping out of a second-floor bedroom window in a suicide attempt after the kids were killed. 

She has pleaded not guilty to three counts of first-degree murder by reason of insanity, claiming that she was suffering severe postpartum depression and psychosis at the time. 

Reddington has argued that his client was heavily overmedicated after being prescribed 13 different drugs from multiple providers, including Tufts. 

And on Monday, Reddington didn't hold back when it came to questioning Tufts's credibility in the medical field. 

Reddington looked directly at Tufts and asked: 'Do you understand that, if, in fact, it's determined that you advertised an expert in postpartum and in postpartum psychiatry, and you have a month of experience, plus a residency, would you consider that to be negligent or a misrepresentation?' 

'I do not believe that I have been negligent,' she replied before Reddington quipped back: 'Do you understand what misrepresentation means?' 

'Yes,' the psychiatrist replied before the defense lawyer added: 'With a month under your belt, plus your residency, do you really want this jury to believe you were an expert? Do you advertise that?' 

Tufts responded: 'I don't think that's exactly the wording that I used. I think I said that it was an interest of mine... I don't believe I called myself an expert.' 

'Are you an expert in postpartum?,' Reddington questioned. 'I may be, I don't know, I think it depends what you find an expert as,' the witness replied. 

According to Tufts' profile page for Aster Mental Health, a mental health practice in Massachusetts, her 'areas of specialty include PTSD and trauma-related disorders, mood disorders, anxiety, OCD, ADHD, and substance abuse.' 

She also has a 'particular interest in women's mental health,' including perinatal psychiatry from pregnancy through two years postpartum.' 

In another intense exchange with Reddington, Tufts appeared to snap at the attorney after he questioned notes she had taken during a visit with Clancy. 

'No sleep last night. Falls asleep after 40 minutes. Heart racing, severe anxiety. Worrying about kids, baby, sleep. Yawns, but not drowsy. Not hyper, pressured speech,' she read from the sheet in front of her. 

Reddington then interjected, asking: 'What was that? Not hyper what?' 

Tufts immediately defended herself, stating: 'No hyper, not pressured speech is what I meant. I know it doesn't say not, but that is exactly what I meant.' 

Reddington then took the paper from her and asked when she realized the mistake in her notes. 

She then snapped, telling him: 'I don't care what it says. I know what I meant!' 

Clancy's lawyer then went over Tufts's medical notes again to try and prove his point, leading the doctor to claim he was 'misinterpreting' what she wrote. 

Reddington continued to question her over it as Tufts became visibly upset, shaking her head and breathing heavily into the microphone for all to see and hear. 

During his time with Tufts, Reddington also quizzed her about the number of postpartum patients she treated before Clancy, the level of contact she had with his client's family, how much she questioned the mother when she admitted to feeling depressed, and if she had penned any medical articles about postpartum mental health. 

Tufts and another doctor who treated Clancy before the murders, Alia Goodheart, are at the center of civil lawsuits that were filed earlier this year by her and her ex-husband, Patrick Clancy. 

The filings allege that the two medical professionals overmedicated Clancy and failed to properly diagnose her following the birth of her youngest child, Callan. 

In April, they both argued that the children's deaths 'were not reasonably foreseeable.' The civil suits are still making their way through the courts.

Tufts obtained a degree in psychology from Cornell University, an Ivy League school, in 2014, according to her LinkedIn. 

She then attended the University of Vermont, where she obtained her medical degree in 2018. 

She then completed her medical residency at Boston University in July 2022, and in that same month, she started at Aster Mental Health. 

The doctor lives comfortably at a home worth nearly $1.7 million in Marblehead that comes with a spacious wrap-around porch, public records show. 

She married her husband, Roger Tufts, in July 2012, previous Facebook posts revealed. 

The Daily Mail contacted Tufts for comment.
