A prosecution psychiatrist told jurors there was no evidence Lindsay Clancy was psychotic when her three children were killed, challenging the core of her insanity defense.
Story Snapshot
- Prosecution expert Dr. Avram Mack testified Clancy showed no psychosis in his evaluation and records review.
- Defense expert Dr. Phillip Resnick said Clancy was “frankly psychotic” and driven by a command hallucination.
- Mack said the most supportable diagnosis for the period was major depressive episode, not psychosis.
- Insanity defenses are rare and succeed in a small minority of cases nationwide.
Prosecution Expert Says Records Do Not Show Psychosis
Prosecutors called forensic psychiatrist Dr. Avram Mack, who interviewed Lindsay Clancy in April 2026 and reviewed medical and forensic records. He told jurors Clancy was cooperative and oriented, with distress and tears, but no signs of delusions or being out of touch with reality. He said her presentation and the record did not show psychotic features around the offense. He concluded the evidence best fit a major depressive episode, not psychosis.
Dr. Mack also addressed criminal responsibility under Massachusetts law. He testified Clancy understood what she was doing was wrong. He pointed to actions that suggested awareness, including sending her husband out of the house and expressing fear that authorities would take her children if people learned her thoughts. He said those details showed she could appreciate wrongfulness and plan her conduct, which weighs against an insanity finding.
Defense Expert Claims Postpartum Psychosis Drove the Killings
The defense’s lead forensic psychiatrist, Dr. Phillip Resnick, offered the opposite view. He said Clancy was “frankly psychotic” at the time of the killings and suffered postpartum psychosis. He told jurors she experienced a command hallucination and a delusion of influence, describing it as an external force taking over her body. He said she believed sending her children to heaven would spare them suffering without her care.
Dr. Resnick said that, during the critical window, Clancy could not conform her conduct to the law due to mental disease. He added she was not psychotic at every moment that day, but became psychotic when the alleged command occurred. His testimony aimed to meet the legal test by showing she lacked control and the ability to judge right from wrong at the time of the act, despite periods of normal functioning.
How Juries Weigh Insanity Claims In Rare Cases
Legal standards focus on whether a severe mental disease left a defendant unable to understand wrongfulness or follow the law at the time of the act. Research shows the insanity defense is raised in well under one percent of felony cases, and it succeeds in only a fraction of those. Studies place success rates near one quarter, depending on the jurisdiction and method. Juries often look for clear psychosis evidence tied to the offense window before acquitting on insanity.
This clash of experts will likely turn on specifics the jury can see and verify. Mack points to cooperation, orientation, and planning as evidence of sanity. Resnick points to alleged commands, loss of control, and a belief about heaven as evidence of psychosis. The stakes are high. A guilty verdict brings punishment. An insanity verdict brings treatment and secure hospitalization. The law demands proof that goes beyond sadness or fear to documented loss of reality at the key moment.
