A psychiatrist who testified that Lindsay Clancy should be held criminally responsible for killing her children is ‘no longer employed,’ it has been reported.
Avram Mack evaluated Clancy — who strangled her three children, Cora, five, Dawson, three, and Callan, eight months, to death in January 2023 —ahead of the trial.
He then testified in the Massachusetts courtroom on August 21 and remotely via Zoom on August 24, where he had a tense exchange with Clancy’s lawyer, Kevin Reddington.
Mack reportedly told jurors that he believed Clancy understood what she was doing to her children was wrong when she killed them.
The psychiatrist claimed in the courtroom that he saw zero evidence of ‘psychotic features’ in Clancy’s medical records.
Mack ultimately formed the opinion that Clancy was suffering from a major depressive episode. He told jurors: ‘While depressed, her mental state was relatively stable.’

Mack, who worked for Delaware’s Nemours Children’s Health, reportedly resigned following his testimony.
A Nemours spokesperson said: ‘Avram Mack is no longer employed by Nemours Children’s Health, he resigned on Monday, August 24th.’
However, they failed to elaborate why Mack left his position, saying ’employment decisions are confidential.’
Clancy does not dispute killing her children but has pleaded not guilty to murder, with her lawyers arguing she was in the throes of postpartum psychosis and taking powerful drugs to cope with depression at the time, leaving her not criminally responsible for her actions.
Mack’s opinion challenged defence expert Dr Phillip Resnick’s testimony, who told the jury that Clancy was ‘frankly psychotic’ when she carried out the killings, having experienced a command hallucination.
This is an auditory verbal hallucination where a person hears a voice that instructs them to perform a specific action.

In contrast, Mack — who only evaluated Clancy’s mental state in April 2026 — also told jurors that he would not have diagnosed her as bipolar.
He added that it was difficult to diagnose, in part, ‘because of all the diagnoses in the records and all the symptoms that she experienced.’
But although Mack agreed that Clancy was ‘in a serious psychiatric state and she was suffering,’ he stated that she should be held criminally responsible for her children’s deaths.
Reddington’s fierce cross-examination saw him challenge Mack about his knowledge of postpartum conditions, and his experience treating adults.
The pair argued over the meaning of ‘postpartum,’ with Mack claiming that symptoms of postpartum depression and psychosis typically only appear four to six weeks after the birth of a child.

This is something Reddington strongly contested, as Clancy killed her children eight months after her third child was born, before attempting suicide, which left her partially paralysed.
At one point during his testimony, Mack reportedly smirked in the courtroom while Reddington questioned his experience.
The defence lawyer reacted to his facial expressions, snapping: ‘What are you smiling for? This is not funny, sir.’
Judge William Sullivan also reprimanded Mack at one point in the questioning, when he gave answers beyond what was being asked of him.
The judge told him: ‘Doctor please. Listen to the question, and just answer the question, as asked.’
He also later reportedly said: ‘You don’t really ask a lot of questions. You answer the questions.’

Clancy killed Cora, Dawson, and Callan with resistance bands while her ex-husband and father of her children, Patrick Clancy, was running errands.
Lindsay had previously sought help from specialists in postpartum mental health and was put on several medications before checking into a psychiatric hospital.
She was discharged from their care, and killed her children 19 days later.
Lindsay and Patrick have accused medical professionals of failing to properly diagnose, treat, and monitor her ahead of the killings.
Prosecutors, however, allege that Lindsay deliberately sent Patrick out of their home on an errand to give her enough time to strangle the children to death.

On Friday, closing statements were made by the defence and prosecution, following a lengthy five-week trial.
It’s a case that has drawn worldwide attention to postpartum mental health, and sparked widespread recognition and outrage over the barriers women face in accessing care, and the lack of research into postpartum mental health conditions.
If convicted by a jury, Clancy faces life in prison without parole. If jurors find her not guilty because she lacked criminal responsibility, Clancy could be committed to a psychiatric facility.
