The murder trial of Lindsay Clancy took a tense turn Monday as defense attorney Kevin Reddington subjected psychiatrist Dr. Jennifer Tufts to hours of aggressive questioning over the treatment Clancy received in the months before the deaths of her three children. The defense focused heavily on whether Tufts properly recognized the severity of Clancy’s deteriorating mental state and whether the medication decisions made during that period may have played a role. 

Tufts treated Clancy from September 2022 until the day before the January 2023 killings. She testified that she diagnosed Clancy with anxiety and an adjustment disorder, but did not diagnose postpartum psychosis or bipolar disorder—conditions the defense now argues were central to what happened. Tufts also said Clancy never told her that she was hearing voices or having thoughts of harming her children. c

But the defense seized on the limits of that treatment. Reddington questioned Tufts about short, approximately 25-minute virtual appointments, her reliance on computerized records and the repeated changes to Clancy’s psychiatric medications. The questioning was designed to challenge whether the psychiatrist had enough information to understand what was happening to her patient as her condition deteriorated. c

One particularly significant issue involved Clancy’s medical history. Tufts acknowledged that she did not have access to the complete record of an emergency-department visit, raising questions about whether crucial warning signs may have been missing from the information available to her when she made treatment decisions.c

The defense is attempting to build a much larger argument from those details: that Clancy’s mental illness was misunderstood, that her treatment was inadequate, and that the combination of psychiatric symptoms and medications contributed to a severe deterioration that culminated in the deaths of her children. Clancy has pleaded not guilty by reason of insanity and claims she was suffering from postpartum psychosis.

The prosecution, meanwhile, has pointed to evidence suggesting Clancy remained capable of carrying out ordinary activities shortly before the killings, making her mental state and level of awareness one of the central battles of the trial.

Now, as the courtroom turns increasingly toward the question of what doctors knew—and what they failed to know—the psychiatrist’s testimony could become one of the most closely scrutinized parts of the defense case.

But the most revealing detail may be what was missing from Clancy’s medical records at the time—and whether that missing information could have changed the treatment she received just days before the tragedy.
