What David Gelman Told Fox News About The Lindsay Clancy Trial And The Insanity Defense
By Gelman Law, LLC
If you have ever watched a case like this and wondered how someone could be found not guilty of a killing they clearly carried out, you are not alone. That question sits at the center of the Lindsay Clancy trial, and it is one a New Jersey criminal defense attorney answers for families every week. Mental illness, criminal responsibility, and the insanity defense are among the hardest ideas in criminal law to explain, and they are harder still when your own family member is facing charges.
David Gelman, the founding attorney at Gelman Law, LLC, recently joined Fox & Friends First to break down the Clancy case for a national audience. He has become one of the legal analysts news networks call when a trial turns on a hard legal question. In that segment, he explained what the defense was doing, why the psychologist’s testimony mattered, and how a jury weighs a claim that a person could not appreciate the wrongfulness of what they did.
In this post, we break down David’s on-air comments, explain what a mental disease defense actually involves, and consider how these same legal questions would unfold under New Jersey law. If you or someone close to you is confronting serious criminal charges and mental health is part of the picture, you don’t have to navigate it by yourself.

David Gelman On Fox News: What Did He Say About The Lindsay Clancy Trial?
Lindsay Clancy is the Duxbury, Massachusetts mother charged with three counts of first-degree murder in the 2023 deaths of her three young children, Cora, Dawson, and Callan. Her defense is that she was in the grip of postpartum psychosis and was not criminally responsible for her actions. When David joined the broadcast, the defense had just rested its case, and the host asked whether that early finish signaled confidence.
David’s read was measured. He noted the defense had put on the case it wanted, made sure the jury heard everything, and chose not to drag things out. By wrapping up when they did rather than prolonging it, he said, the defense “definitely makes a good impression.” He framed the trial as a contest between the two sides and their competing forensic witnesses, leaving the jury to decide whose account of Clancy’s mental state to believe.
The conversation then turned to the most important witness. The host noted that the psychologist who treated Clancy after the killings carried more weight than a hired evaluator, because that clinician testified Clancy could not appreciate the wrongfulness of her actions. David agreed this was close to the whole case. He called it “such a weird case because all of America is watching this and it’s really divided,” and said testimony like that “is reasonable doubt. And that is exactly what the jury will be looking at when they deliberate in the jury room.”
That single point is why this trial matters far beyond Massachusetts. The same tension appears in many cases where a defendant’s mental state is in question, and it is often where a case is won or lost.
Not Criminally Responsible: What Does A Mental Disease Defense Actually Mean?
The insanity defense does not argue that the defendant did not commit the act. It argues that the person’s mental state at the time removed their legal responsibility for it. That is a narrow and demanding standard, nothing like the way the phrase gets tossed around in everyday conversation.
In Massachusetts, a defendant can be found not criminally responsible if, because of a mental disease or defect, they lacked substantial capacity to appreciate the wrongfulness of their conduct or to conform it to the law. That is why the treating psychologist’s testimony carried such weight. If the jury believes Clancy truly could not understand that what she was doing was wrong, the foundation for a guilty verdict starts to weaken.
David’s reference to reasonable doubt was not casual. Massachusetts places a heavy burden on the prosecution once the issue is raised. Consider how the pieces fit together:
- Mental disease or defect: the defense must point to a recognized condition affecting the mind, such as postpartum psychosis
- Appreciating wrongfulness: the jury asks whether the person could grasp that the act was wrong
- Prosecution’s burden: in Massachusetts the state must prove criminal responsibility beyond a reasonable doubt
- The verdict choice: jurors weigh murder, manslaughter, or a finding of not criminally responsible
A finding of not criminally responsible is not a walk out the door. It usually means long-term commitment to a secure state psychiatric facility, with periodic review and no guaranteed release date. The stakes stay enormous, which is one reason these cases draw so much attention.
The Insanity Defense In New Jersey: How Would This Case Work Under Garden State Law?
The Clancy trial is a Massachusetts case, and the law there is not the law that applies in South Jersey. If a similar situation arose in Camden County or Burlington County, a New Jersey criminal defense attorney would work from a different rulebook, and the outcome can hinge on that difference.
New Jersey applies the M’Naghten standard, which is codified at N.J.S.A. 2C:4-1. The provision excuses a defendant from criminal responsibility when a mental disease so impaired their reasoning at the moment of the offense that they either failed to understand what they were actually doing, or, while understanding the act itself, could not recognize that it was wrong. Compared with the standard used in Massachusetts, New Jersey’s version reaches fewer defendants: it asks only whether the person could distinguish right from wrong, and it does not consider whether the person was capable of controlling their behavior to comply with the law.
The way the burden is allocated also differs in New Jersey. Because insanity operates as an affirmative defense, the obligation falls on the accused to establish it by a preponderance of the evidence, instead of requiring prosecutors to refute it beyond a reasonable doubt. A more limited option exists as well. N.J.S.A. 2C:4-2 allows a defendant to introduce proof of a mental disease or defect where that proof bears on whether they possessed the particular mental state the charge requires, a theory usually labeled diminished capacity. This does not absolve the defendant of the act; instead, it undercuts one of the components the prosecution must establish, meaning that after the evidence comes in, the State remains responsible for proving the necessary mental state beyond a reasonable doubt.
If a New Jersey jury returns a verdict of not guilty by reason of insanity, the case does not simply end. Under N.J.S.A. 2C:4-8 and the framework from State v. Krol, the court can order commitment to a psychiatric facility with ongoing review of whether the person remains dangerous. In plain terms, an insanity verdict here often trades prison for indefinite treatment and supervision, not freedom.
Why People Turn To David Gelman: What Makes A Trusted Legal Analyst?
There is a reason networks like Fox News call David Gelman when a case reaches the jury, and it is the same reason New Jersey clients call him when their freedom is on the line. He is a former Burlington County prosecutor who now runs a criminal defense practice, so he has argued these issues from both sides of the courtroom. That lets him explain not just what a lawyer is doing, but why.
In a single broadcast, David can move from a mental disease defense in a Massachusetts murder trial to a separate high-profile hearing out of Texas without missing a beat. He answers plainly, does not oversell, and tells viewers what the evidence really means rather than what makes the flashiest headline. That is the same approach he brings to a consultation at Gelman Law, LLC.
For a client, the television appearances are not the point. What matters is that the attorney handling your case has thought hard about how juries react, how prosecutors build their proof, and where a defense can find reasonable doubt. Whether your matter sits in a Camden County courtroom or a Burlington County one, that judgment is what you are hiring.

The 2026 Update: Where Does The Lindsay Clancy Case Stand Now?
The Clancy trial reached its most important stage in the late summer of 2026. After both sides rested and delivered closing arguments, jurors in Duxbury began deliberating whether postpartum psychosis left Clancy unable to appreciate the wrongfulness of her actions. As of early September 2026, the jury had deliberated for several days without reaching a verdict.
That deadlock is not surprising, and it lines up with what David described on air. This is a divided case, the treating clinician’s testimony cuts hard toward reasonable doubt, and the jurors are weighing murder, manslaughter, or a finding that Clancy was not criminally responsible. However the jury lands, the case has already brought maternal mental health and the limits of the insanity defense into national view.
For New Jersey families, the takeaway is not about one Massachusetts verdict. It is that mental health can be central to a criminal case, and how it is raised and supported makes an enormous difference.
Charged With a Serious Crime in New Jersey? Here’s How to Move Forward
In cases where mental health is a factor, the choices you make at the outset can influence how the entire matter unfolds. These are the areas worth prioritizing:
- Say little to law enforcement: resist the urge to walk investigators through your mental health history on your own
- Safeguard your medical records: collect treatment notes, medication lists, and the names of your providers before any of it becomes hard to recover
- Document the sequence of events: jot down dates, symptoms, and hospitalizations while your memory of them is still sharp
- Point to the clinicians who treated you: a provider who actually cared for you often carries more credibility than someone brought in for a single evaluation
- Bring in a defense attorney right away: the earlier counsel gets involved, the earlier work on the defense can begin
A compelling mental health defense isn’t something an attorney throws together in the final days before trial. It’s built from records, witnesses, and thorough evaluation, all of which take time to come together. Getting started early gives your defense the space it needs to develop.
Frequently Asked Questions About The Insanity Defense In New Jersey
Is the insanity defense the same as pleading not guilty by reason of insanity?
In practice, yes. A not guilty by reason of insanity plea asserts that a mental disease or defect made the person not criminally responsible under New Jersey law, specifically N.J.S.A. 2C:4-1.
Does an insanity verdict mean a person goes free?
No. In New Jersey, a not guilty by reason of insanity verdict can lead to commitment in a psychiatric facility with periodic review, so the outcome is treatment and supervision rather than release.
What is the difference between insanity and diminished capacity in New Jersey?
The insanity defense argues a person did not know their act was wrong. Diminished capacity under N.J.S.A. 2C:4-2 argues a mental condition kept the person from forming the specific intent the charge requires.
Can postpartum psychosis factor into a criminal defense?
Yes, it can. Postpartum psychosis is an established psychiatric condition, and evidence that a defendant was experiencing it may help support an insanity or diminished capacity defense, depending on the specific circumstances of the case and the law of the jurisdiction where it is being tried.
