David Gelman On The Lindsay Clancy Trial: When Does Mental Illness Mean Someone Is Not Criminally Responsible?
By The Criminal Defense Team At Gelman Law, LLC
If you have followed the Lindsay Clancy trial, you already know how hard these cases are to watch. A Massachusetts mother admits she killed her three young children in 2023, yet her lawyers argue she was in the grip of postpartum psychosis and could not understand what she was doing. Cases like this raise a question that comes up more often than most people realize, including here in New Jersey: when does a serious mental illness mean a person is not criminally responsible for what happened? If you are trying to understand the insanity defense in New Jersey because someone you love is facing charges and struggling with mental illness, you are in the right place, and you are not alone in feeling overwhelmed.
Firm founder David Gelman recently sat down with Fox News to discuss the Clancy case, and one of his points cuts to the heart of every case like this. As he put it, it is often not a whodunit. Everyone may agree on who did something. The real fight is whether the person could appreciate their actions at the very moment it happened. That single question can change everything about how a case is charged, tried, and resolved.
If you are dealing with a situation like this, you do not have to figure it out by yourself.

Postpartum Psychosis And Criminal Responsibility: Why The Lindsay Clancy Trial Has The Country Watching
The Clancy case has drawn national attention because it forces the public to confront an uncomfortable truth about mental illness and crime. Prosecutors say Lindsay Clancy acted intentionally and rationally, that she planned the day, sent her husband out of the house, and later tried to hide what she had done. Her defense team argues she was suffering from severe postpartum psychosis, made worse by bipolar disorder and by medication prescribed after the birth of her third child. Both sides agree on the terrible facts. They disagree completely on whether she was criminally responsible.
That divide is exactly what a jury has to sort through. In his Fox News interview, David Gelman explained that these trials often become a contest between the psychiatric professionals on each side, and the jury tends to side with whichever explanation it finds most believable. He also noted how difficult that is when children have died, because jurors are human and the facts are heartbreaking.
There is also a quieter legal story inside the Clancy case that matters to families in New Jersey. Her ex-husband asked the court to keep the 911 call and photographs of the children away from the public. Gelman pointed out that while a father wanting to protect his family is completely understandable, the evidence is still relevant, and a judge is more likely to issue limiting instructions than to hide it entirely. These are the kinds of practical tensions that play out in serious cases every day.
The Insanity Defense In New Jersey: How Does N.J.S.A. 2C:4-1 Actually Work?
New Jersey has its own answer to the question of criminal responsibility, and it is set out in the criminal code. Under N.J.S.A. 2C:4-1, a person is not criminally responsible for their conduct if, at the time of the act, they were suffering from such a defect of reason, from a disease of the mind, that they did not know the nature and quality of what they were doing, or, if they did know it, that they did not know it was wrong. This is the traditional standard many people know as the M’Naghten rule.
The wording matters, so it helps to break it down in plain English. The law is not asking whether a person was mentally ill in a general sense. It is asking a narrow question about a specific moment in time. Here is how that plays out in practice:
- Timing matters most: The focus is on the defendant’s state of mind at the exact time of the alleged offense, not weeks before or after
- Knowing the act: The question is whether the person understood what they were physically doing
- Knowing right from wrong: Even if they understood the act, the law asks whether they could grasp that it was wrong
- Disease of the mind: There must be a genuine mental disease or defect driving the inability to understand, not simply anger, stress, or a bad decision
Because the standard is so specific, an insanity defense in New Jersey almost always turns on detailed testimony from qualified medical and psychiatric witnesses who can explain the person’s condition to the jury.
It is also important to understand who has to prove what. Insanity is an affirmative defense in New Jersey, which means the burden falls on the defense rather than the state. The defendant must show by a preponderance of the evidence, meaning more likely than not, that the standard was met at the time of the offense. That is a lower bar than the prosecution’s burden of proof beyond a reasonable doubt, but it still requires strong, credible, and well-supported evidence. New Jersey courts have made clear that qualified opinion testimony is generally needed to meet this standard, which is why the right medical witnesses are so important.
Diminished Capacity In New Jersey: Can Mental Illness Matter Even When Insanity Does Not Apply?
Many people assume that mental illness is only relevant if it leads to a full finding of insanity. That is not how New Jersey law works. Even when a defendant does not meet the strict test under N.J.S.A. 2C:4-1, evidence of a mental disease or defect can still play a major role in the case.
Under N.J.S.A. 2C:4-2, evidence of a mental condition can be admitted to show that a defendant did not have the state of mind required for a particular offense. Many serious crimes require the state to prove that a person acted purposely or knowingly. If a mental illness prevented someone from forming that specific mental state, the evidence may reduce the level of the offense or affect which charges can stand. This is often described as diminished capacity, and it can be a powerful tool even when a full insanity defense is not realistic.
The takeaway for families is simple. Mental illness is rarely all or nothing in the eyes of New Jersey law. There is often a range of ways it can shape a case, from the charges themselves to the outcome, and a careful defense looks at every one of them.
Mental Illness And A Criminal Case In New Jersey: What Should You Do Next?
When a loved one is arrested and mental illness is part of the picture, the early decisions you make can shape everything that follows. It is easy to feel paralyzed, but a few clear steps can protect the person you care about.
- Say less to police: Encourage your loved one to remain silent and avoid explaining anything to investigators until a lawyer is involved
- Preserve medical records: Gather treatment history, hospital records, prescriptions, and the names of treating providers
- Write down the timeline: Note recent changes in behavior, sleep, medication, and mood while the details are fresh
- Avoid public statements: Keep details off social media and away from anyone outside the legal team
- Call a lawyer quickly: Get experienced criminal defense counsel involved as early as possible so evidence can be protected
Taking these steps early gives your defense team the raw material it needs to tell the full story of what was happening in a person’s mind, which is often the difference between a case that is understood and one that is not.

Frequently Asked Questions About The Insanity Defense In New Jersey
Is the insanity defense the same in New Jersey as in the Lindsay Clancy trial?
Not exactly. The Clancy case is being tried under Massachusetts law, while New Jersey follows N.J.S.A. 2C:4-1 and the M’Naghten standard. The core question is similar, whether the person could understand the nature of the act or that it was wrong, but the specific rules and procedures depend on the state where the case is filed.
Who has to prove insanity in a New Jersey criminal case?
In New Jersey, insanity is an affirmative defense, so the defense must prove it by a preponderance of the evidence. That means showing it was more likely than not that the person met the legal standard at the time of the offense. Qualified medical and psychiatric testimony is generally required.
Can postpartum psychosis be a defense in New Jersey?
It can be relevant. Postpartum psychosis is a recognized and serious mental illness, and evidence of it may support an insanity defense or a diminished capacity argument, depending on the facts. Every case turns on the individual circumstances and the supporting medical evidence, and no result can ever be promised.
What is the difference between insanity and diminished capacity in New Jersey?
Insanity under N.J.S.A. 2C:4-1 can lead to a finding that a person is not criminally responsible at all. Diminished capacity under N.J.S.A. 2C:4-2 uses evidence of mental illness to show that a person could not form the state of mind a specific charge requires, which may reduce or change the charges even when a full insanity defense does not apply.
Do I need a lawyer if my family member has a documented mental illness?
Yes. A documented mental illness is helpful, but it does not automatically resolve a criminal case. Experienced defense counsel can gather the right records, work with medical professionals, and present the evidence in a way that meets New Jersey’s demanding legal standards.
