Dr. Avram Mack, the prosecution’s rebuttal witness in the Lindsay Clancy case, has resigned from Nemours Children’s Health in Delaware — the same day his contentious cross-examination concluded.
CT Insider reported Friday that the psychiatrist was no longer employed at the hospital. Nemours later confirmed Mack resigned Monday, hours after defense attorney Kevin Reddington finished questioning him on the witness stand.
“Dr. Avram Mack is no longer employed by Nemours Children’s Health,” a spokesperson told the outlet, declining further comment. “Employment decisions are confidential.”
The Daily Wire confirmed independently that Mack’s name no longer appears in the Nemours physician directory.
Mack had been employed at Nemours Children’s Health in the Delaware Valley since 2023, according to the resume he submitted during his testimony. He trained at Columbia and has largely practiced child and adolescent psychiatry — a credential Reddington hammered during cross-examination.
“What are you smiling for? This is not funny, sir.”
The defense attorney pressed Mack on his limited experience evaluating adult patients. During the trial, Mack and Reddington clashed repeatedly over the definition of “postpartum” and the typical timeframe for postpartum depression and psychosis.
Mack testified he did not consider postpartum-specific conditions in his evaluation of Clancy, citing guidelines that limit the postpartum period to four weeks after birth. Reddington and other experts disputed that narrow window, with some testimony extending the postpartum period to a year or more.
At one point during the heated cross-examination, Mack appeared to smile. Reddington scolded him: “What are you smiling for? This is not funny, sir.”
Mack argued for the prosecution that Clancy should be held criminally responsible for the strangulation of her three young children despite conceding she was “in a serious psychiatric state and she was suffering.”
He stated he observed no evidence of manic episodes, leading him to conclude Clancy was not suffering from bipolar disorder. He also said some of the fears she expressed — that something might happen to her children, or that someone might take them away — were within the normal range for mothers.
Defense witness Dr. Phillip Resnick testified to the opposite scenario. Saying he believed Clancy to be “frankly psychotic,” Resnick said she had experienced “command hallucinations” in which a male voice instructed her to harm her children.
Other testimony questioned why she heard the voice only briefly — an atypical presentation — and why it stopped as soon as she finished strangling the children.
Dr. Gregory Saathoff, who interviewed Clancy in May and June of 2026, noted that Clancy had piled on extra errands to ensure her husband, Patrick Clancy, would be away from the house longer.
Prosecutor Jennifer Sprague closed the state’s case by arguing Clancy “acted intentionally, rationally and swiftly” when she took her children’s lives.
“I’m not saying she was happy about it. I’m saying, it was what she had to do to end her misery. But it was a choice. It was a choice.”
Reddington attempted to blame Clancy’s condition on psychiatric medication she’d been prescribed — some of which she reportedly either did not take at all or did not take reliably — saying she’d been failed by the system “because of the damn medicine and the lousy medical care that she got.”
The jury deliberated for about three-and-a-half hours on Thursday and roughly seven hours on Friday. They are expected to resume deliberations Monday.
If the jury finds Clancy criminally responsible, she will likely face life in prison without the possibility of parole. If they find her not guilty by reason of lack of criminal responsibility, prosecutors can petition the court to have her remanded to a psychiatric facility.
The charges remain allegations. The case has not been proven in court.
