Wilmington, Del. — A psychiatrist who provided expert testimony in the trial of Lindsay Clancy has resigned from his clinical post at Nemours Children’s Health in Delaware, the hospital system confirmed Friday.
Resignation came during trial testimony
Dr. Avram Mack submitted his resignation on Aug. 24, according to a Nemours spokeswoman. The hospital said his forensic work as an expert witness was conducted through his private practice and was separate from his responsibilities with Nemours’ behavioral health department.
Mack testified for the prosecution over two days in the case involving Clancy, who is charged in the 2023 deaths of her three children in the family’s Duxbury, Massachusetts, home. During testimony, Mack described his April interview with Clancy and explained his clinical conclusions about her mental health.
He said he believed Clancy should be held criminally responsible in the deaths of her three children.
Prosecutors presented Mack as a forensic expert who assessed whether Clancy’s mental state met the legal standards for an insanity defense. In court, he testified that he did not find evidence supporting a diagnosis of bipolar disorder and instead felt her symptoms aligned more closely with major depressive disorder — and that she retained control over her actions.
Nemours statement and unanswered questions
The health system declined to provide a reason for Mack’s departure beyond confirming the effective resignation date. Nemours emphasized that the expert-witness work he offered in the Clancy prosecution was separate from his hospital duties.
Hospital officials did not respond to follow-up questions about whether the resignation was voluntary or whether it followed any internal review. It also was not disclosed whether Mack will continue his forensic work in a private capacity.
Local and legal context
The resignation draws attention because Nemours is a prominent pediatric health system in Delaware and the Mid-Atlantic. For local readers, the situation highlights the intersection between clinical practice at a major hospital and private forensic work that employees may undertake outside their institutional roles.

Why the distinction between clinical and forensic roles matters
Medical professionals who testify in criminal cases generally do so through private forensic practices. Hospitals often draw a line between clinicians’ responsibilities to their patients and any expert opinions they offer in legal settings. Nemours’ statement reiterated that separation but did not disclose whether the hospital has specific policies regulating outside forensic work by clinical staff.
For the public, the case raises questions about how health systems monitor potential conflicts of interest and how they respond when staff are involved in high-profile legal matters. Local advocacy groups and legal experts say transparency about institutional policies can help maintain trust when employees participate in criminal proceedings.
What’s next in the Clancy case
At the time of Mack’s resignation, court proceedings in the Clancy case were moving toward deliberations. The jury consists of nine women and three men, and legal filings indicate deliberations resumed after closing arguments. The jury will determine whether Clancy can be held criminally responsible for the deaths of her children under applicable standards for mental illness and culpability.
Nemours did not indicate whether it would comment further about Mack’s resignation or whether the hospital will review policies concerning outside expert work by its clinicians. Mack’s private practice status means he may continue forensic work independent of Nemours, but his future professional roles were not detailed in the hospital’s statement.
The developments at Nemours add a Delaware connection to a case that has drawn national attention for its legal and psychiatric issues. Local public-health officials and legal observers say the situation underscores the sometimes-complicated role of clinicians who serve on both sides of medicine and the courts.
