Criminal defense attorney Kevin Reddington continued presenting a psychiatric defense in the high-profile murder trial of Lindsay Clancy, as a forensic psychologist described what he believed was a severe mental health crisis before the deaths of her three children.
The trial in Plymouth Superior Court was briefly interrupted Wednesday when Judge William Sullivan sent jurors home for the day because of an “unforeseen circumstance.” The judge did not explain the reason for the delay and instructed jurors not to speculate or hold the interruption against either side.
Testimony is scheduled to resume at 9 a.m. Thursday. Clancy faces three counts of first-degree murder in connection with the deaths of her 5-year-old daughter, Cora; her 3-year-old son, Dawson; and her infant son, Callan.
Criminal Defense Attorney Builds Case Around Postpartum Psychosis
Clancy has pleaded not guilty. Her defense does not dispute that she was responsible for the children’s deaths, but argues that she should not be held criminally responsible because she was experiencing postpartum psychosis at the time.
Reddington has argued that Clancy’s mental state prevented her from understanding the wrongfulness of her actions or following the law. The defense’s strategy has centered on medical records, psychiatric treatment and testimony from experts who evaluated Clancy after the January 2023 incident.
Clinical and forensic psychologist Paul Zeizel returned to the witness stand Wednesday. Zeizel told jurors that he had met with Clancy approximately 60 times over the past three years, including during the trial. Although he did not treat her before the killings, he reviewed extensive medical records from other providers.
According to Zeizel, Clancy’s condition deteriorated during late 2022. He described symptoms including derealization, disassociation, brain fog, intrusive thoughts and concerns that other people could hear her thoughts.
“Her concern was that when people could hear her thoughts, her children would be removed from her care,” Zeizel testified.
Powerful Testimony About Intrusive Thoughts and Voices
Zeizel said Clancy’s intrusive thoughts eventually became persistent and overwhelming. In his assessment, she was suffering from bipolar disorder with postpartum psychosis by January 2023.
“Intrusive thoughts are unrelenting,” Zeizel said, explaining that such thoughts can repeatedly interfere with a person’s ability to function. He testified that Clancy reported thoughts telling her to kill herself and that, on Jan. 24, 2023, she could no longer distinguish right from wrong.
Zeizel also described a phone call between Clancy and her then-husband, Patrick Clancy, approximately two weeks after the killings. The psychologist said Clancy had asked to speak with Patrick while hospitalized and guarded by officers.
During a later speakerphone call, Zeizel testified, Clancy told Patrick that she loved him and said she had heard a male voice ordering her to kill the children and then herself.
He said Clancy has not reported hearing voices since the events in 2023. Zeizel also acknowledged that her medical records before the killings did not specifically document a voice in her head, although they did reflect intrusive thoughts and other troubling symptoms.
Prosecutors Challenge the Mental Health Defense
Prosecutors have questioned the timing and reliability of Clancy’s account of hearing a male voice. They have also suggested that the idea may have been introduced during her early meetings with Zeizel, an allegation the defense has sought to rebut.
A hospital officer previously testified that there was no evidence Zeizel planted the idea. Zeizel said he learned additional details about the alleged voice from a hospital chaplain and denied conducting a “fishing expedition.”
The prosecution also challenged whether Zeizel’s dual role as evaluator and treating clinician could have influenced his conclusions. Prosecutors raised the possibility of confirmation bias, arguing that he could have favored evidence supporting his assessment while overlooking contradictory information.
On redirect examination, Zeizel rejected that suggestion. He said a proper evaluation begins without a predetermined conclusion and that the evidence, rather than personal expectations, should guide the final opinion.
Critical Questions Ahead in the Trial
The jury must ultimately decide whether Clancy is legally responsible for the deaths under Massachusetts law. The case has drawn intense attention because it involves a disputed insanity defense, postpartum mental illness and questions about how psychiatric symptoms should be evaluated in criminal court.
Jurors have previously heard that Clancy was prescribed 13 different psychiatric medications during the four months before the killings. Zeizel testified that medication changes may have worsened her condition and emphasized that psychotic symptoms can fluctuate.
“People with psychosis have intermittent symptoms,” he said, comparing hallucinations to waves that come and go.
The defense is expected to rely on expert testimony to argue that Clancy’s actions occurred during a profound psychiatric episode. Prosecutors, meanwhile, are expected to continue testing the credibility of that explanation and the evidence supporting it.
As reported by ABC News, testimony is expected to continue after the unexpected one-day pause. The case remains ongoing, and any final verdict will depend on the jury’s evaluation of the medical evidence, witness testimony and legal standards governing criminal responsibility.
