Lindsay Clancy live trial today continued in Plymouth Superior Court as prosecutors called their final expert witness in the closely watched murder case. Testimony is expected to conclude Wednesday, Aug. 26, with closing arguments likely to begin Thursday.
Clancy, 36, is accused of strangling her three children at the family’s Duxbury home on Jan. 24, 2023, before attempting to take her own life. She has acknowledged strangling 5-year-old Cora, 3-year-old Dawson, and 8-month-old Callan, but maintains that she was experiencing postpartum psychosis and obeying a commanding voice.
Lindsay Clancy Live Trial Today Brings Final Expert Testimony
The prosecution’s final witness is Dr. Gregory Saathoff, a forensic psychiatrist who also works with the FBI’s Behavioral Analysis Unit in Quantico, Virginia. Saathoff returned to the stand Wednesday after previously telling jurors that Clancy’s descriptions of her alleged hallucinations changed across interviews with mental health experts.
According to testimony reported by Boston.com, Saathoff questioned whether Clancy experienced an acute psychotic episode on the night of the killings. He pointed to text messages, photographs, and other communications that he said portrayed a different picture from the one Clancy later gave investigators and evaluators.
Clancy told Saathoff that a voice repeatedly warned her, “This is your last chance. You have to kill your kids and then kill yourself.” However, Saathoff said the timing and details of the alleged voice varied in her conversations with different experts.
He also described it as unusual that Clancy reported auditory hallucinations only on the evening of Jan. 24, 2023, and never reported them again. The psychiatrist specifically focused on the claim that the voice stopped after Clancy strangled her youngest child, Callan.
Saathoff testified that he had never encountered a command hallucination that was effectively “curative” after a person acted on it. His testimony is central to the prosecution’s argument that Clancy understood her actions and should be held criminally responsible.
Powerful Dispute Over Psychosis and Criminal Responsibility
Another prosecution rebuttal expert, forensic psychologist Kirk Heilbrun, testified Tuesday that Clancy retained control over her behavior during the killings. In his professional opinion, her actions were more consistent with what he described as altruistic filicide than with acute psychosis accompanied by command hallucinations.
Heilbrun said Clancy was depressed, hopeless, and suicidal in the period leading up to the deaths. He argued, however, that she remained aware that killing other people—including her children—was illegal and morally wrong.
The psychologist suggested that Clancy’s desire to die influenced her thinking. He testified that she may have believed she could not leave her children behind if she died, an explanation prosecutors say supports their theory that she made decisions rather than acting without awareness.
Heilbrun also discussed peritraumatic dissociation, a response to trauma that can make events feel unreal or detached. He said Clancy described feeling as though she was watching herself and acting with “no thinking, no decision-making, only responding to the voice and taking action.”
Even so, Heilbrun maintained that signs of dissociation did not eliminate her ability to make choices. During cross-examination, defense attorney Kevin Reddington challenged the expert’s neutrality, suggesting Heilbrun had already viewed Clancy harshly before meeting her. Heilbrun rejected that characterization and said he had tried to approach the evaluation with an open mind.
What Happens Next in the Duxbury Murder Trial?
Judge William Sullivan told jurors that testimony should wrap up Wednesday. Closing arguments are expected Thursday, after which the jury will begin weighing competing accounts of postpartum mental illness, trauma, intent, and responsibility.
The defense is expected to emphasize Clancy’s reported depression and alleged command hallucinations. Prosecutors, meanwhile, are highlighting evidence they believe shows planning, awareness, and decision-making during the deaths.
The case has drawn national attention because it combines a devastating family tragedy with difficult questions about postpartum psychosis, suicide, criminal accountability, and the limits of expert psychiatric testimony. The verdict will determine whether Clancy is held criminally responsible for the deaths of her three children.
