The murder trial of Lindsay Clancy resumed in Massachusetts with further testimony from a forensic psychologist hired by the prosecution. Dr. Kirk Heilbrun returned to the witness stand in Plymouth Superior Court following a previous session that was cut short after he mentioned Clancy’s Catholic religion.
Trial Nears End as Psychologist Testifies Clancy Is Criminally Responsible
Clancy, 36, has pleaded not guilty to first-degree murder charges in the deaths of her three children: 5-year-old Cora, 3-year-old Dawson, and 8-month-old Callan. The children were strangled to death with exercise bands at the family’s home in Duxbury, Massachusetts, on Jan. 24, 2023. While Clancy has admitted to the killings, her defense team argues she should not be held criminally responsible because she was overmedicated and suffering from acute postpartum psychosis.
Testimony on Mental State and Motive
During his testimony, Kirk Heilbrun told jurors that he concluded Clancy was criminally responsible for the deaths of her children. He testified that Clancy retained an awareness of the illegality of her actions.
She retained an awareness of the illegality of killing others, including killing her children,
Heilbrun said, adding that her moral awareness of the wrongfulness of the killings was influenced by a strong desire to die and a feeling that she should not leave her children behind.
Heilbrun cast doubt on Clancy’s claim that she experienced acute psychosis and command hallucinations telling her to kill the children. Instead, he opined that her mental state aligned with altruistic filicide, suggesting she took her children’s lives so they would not suffer after she killed herself. He noted that Clancy reported there was no decision-making involved and that she was responding to a voice, but he stated there were ongoing decisions required to carry out the killings over an 18-to-20-minute span, such as choosing the location and what to say to the children.
Defense Arguments and Courtroom Proceedings
Defense attorney Kevin Reddington cross-examined Heilbrun after previously calling for a mistrial when the psychologist initially discussed Clancy’s religion on the stand. Plymouth Superior Court Judge William Sullivan denied the mistrial request but reprimanded the prosecution and instructed the jury to disregard the religious testimony, telling them it was immaterial and irrelevant. Reddington later remarked that the judge made a good effort with the jury instruction.
Earlier in the trial, medical experts called by the defense testified that Clancy had lost her grip on reality due to postpartum psychosis, a rare mental illness following childbirth. In the months leading up to the tragedy, Clancy had sought mental health treatment from multiple providers and admitted herself to a psychiatric hospital. Following the incident, Clancy jumped from a second-floor window and remains paralyzed from the waist down.
Prosecutors contend that Clancy planned the murders and contrived to get her husband out of the house by sending him to pick up medicine for a child and dinner for the family.
Next Steps in the Case
As the trial neared its conclusion, Kirk Heilbrun finished his testimony as the prosecution’s second rebuttal witness. Once all witness testimony concludes, all sides are scheduled to discuss next steps, with closing arguments anticipated.
If convicted of first-degree murder, Clancy faces life in prison without parole. If the jury determines she was not criminally responsible, she will be sent to a state psychiatric hospital in Massachusetts.
