Lindsay Clancy’s murder trial has gripped the country for a simple reason: it forces an uncomfortable question into the open. When someone commits an unthinkable act while suffering a severe mental health crisis, is that a crime — or a tragedy the law has to treat differently?

The facts aren’t in dispute. Clancy, a former labor and delivery nurse, strangled her three young children in their Massachusetts home in January 2023. She doesn’t deny doing it. Her defense argues she was in the grip of postpartum psychosis and didn’t understand what she was doing. Prosecutors argue she knew exactly what she was doing. After roughly six weeks of testimony from more than 80 witnesses, the jury has now told the judge twice that it cannot reach a unanimous verdict — and as of this week, deliberations are continuing into a sixth day.

Whatever happens in that Massachusetts courtroom, the questions the case has raised are showing up in search bars everywhere, including here in North Texas. And the honest answer to most of them is: it depends entirely on which state you’re in. Massachusetts and Texas handle this scenario very differently. Here’s how it would play out if this case were unfolding in a Texas courtroom.

What Does “Lack of Criminal Responsibility” Mean, and Does Texas Use That Standard?

Massachusetts uses the phrase “lack of criminal responsibility” as its version of the insanity defense. Texas doesn’t use that exact language, but the underlying idea is similar, and it’s found in Texas Penal Code Section 8.01.

Under Texas law, insanity is an affirmative defense. That means the defendant carries the burden of proving it, not the prosecution disproving it, and the standard is preponderance of the evidence — more likely than not. To succeed, the defense has to show two things: that the person was suffering from a severe mental disease or defect at the time of the offense, and that as a result, they did not know their conduct was wrong. Simply having a diagnosed mental illness isn’t enough on its own. The illness has to have actually prevented the person from understanding the wrongfulness of what they were doing at that specific moment.

This is a narrow defense, and Texas juries rarely accept it. That’s part of why these cases draw so much public attention when they do reach trial — a genuine insanity defense is far rarer than television makes it seem.

Can a Texas Judge Force a Deadlocked Jury to Keep Deliberating?

Yes. When a Texas jury tells the judge it’s deadlocked, the judge doesn’t have to accept that at face value, especially early on. Texas courts routinely give what’s known as an Allen charge, sometimes called a “dynamite charge.” The Texas Court of Criminal Appeals approved this practice decades ago in Arrevalo v. State, and it remains standard.

An Allen charge is a supplemental instruction reminding jurors of their duty to deliberate with an open mind, to reconsider their own position in light of what other jurors are saying, and to try to reach a verdict without abandoning their honest conviction. It’s intentionally worded to encourage consensus without pressuring anyone to cave. Judges are careful here because an instruction that crosses the line into coercion can be reversible error on appeal. But a single Allen charge, given after a reasonable period of deliberation, is common and has been upheld again and again in Texas appellate opinions.

Can a Specific “Holdout” Juror Be Removed?

This is one of the most misunderstood parts of jury trials, and it comes up in nearly every high-profile deadlock. The short answer is no — not simply because that juror disagrees with the majority.

A juror can be removed during deliberations only for reasons that have nothing to do with their view of the evidence: things like a serious medical emergency, proof of juror misconduct, or a juror becoming unable to serve. Disagreeing with eleven other people is not a disqualifying reason, and it’s not supposed to be. The entire point of requiring a unanimous verdict is that a single juror’s honest doubt is enough to prevent a conviction. Removing someone specifically because they’re the holdout would gut that protection, and appellate courts treat it as a serious red flag when it looks like that’s what happened.

What Happens If the Jury Stays Deadlocked?

If, even after an Allen charge, a Texas jury genuinely cannot reach a unanimous verdict, the judge will declare a mistrial based on a hung jury. Importantly, a mistrial isn’t an acquittal. The case doesn’t go away. The defendant isn’t convicted, but they aren’t cleared either — the charges simply remain pending, and the prosecution has to decide what to do next.

Prosecutors generally have three options: retry the case in front of a new jury, offer a plea agreement, or, in rarer cases, decide not to pursue it further. Because a hung jury never reaches a verdict, double jeopardy doesn’t bar a retrial. This is exactly the dynamic that played out in the recent Karen Read case in Massachusetts — a first mistrial from a deadlocked jury, followed by a full retrial with a different jury reaching a different result.

What Are the Potential Outcomes and Sentencing Ranges?

In a case like this, a Texas jury would typically be choosing among several possible outcomes: guilty of murder, guilty of a lesser offense like manslaughter, not guilty, or not guilty by reason of insanity. Each carries a dramatically different consequence. A murder conviction in Texas carries a punishment range of five years to life, or life without parole depending on the specific charge and any capital allegations. Manslaughter, a lesser included offense, carries a much narrower range. An acquittal ends the criminal case entirely. And a finding of not guilty by reason of insanity sends the case into an entirely different track — one that has almost nothing to do with prison and everything to do with psychiatric commitment.

What Actually Happens After a “Not Guilty by Reason of Insanity” Verdict?

This is where public perception and reality diverge the most. People often assume NGRI means the person walks free. In Texas, that’s essentially never what happens.

Once a defendant is acquitted by reason of insanity, Texas Code of Criminal Procedure Chapter 46C takes over. Rather than being released, the person is typically committed to a state mental health facility for treatment, or in some cases ordered into an outpatient or community-based supervision program, depending on the risk they’re found to pose. Critically, that commitment isn’t open-ended. Texas law caps the total time someone can be held under this kind of commitment at the maximum prison sentence they could have received for the underlying offense. For a case involving multiple murder charges, that ceiling could functionally mean a lifetime of commitment, reviewed periodically by the court — a very different thing from either “prison” or “freedom.”

Why Do Competing Psychiatric Experts Reach Opposite Conclusions?

One detail from the Clancy trial that resonates with almost every serious mental-health-defense case is this: the prosecution’s expert and the defense’s expert examined the same person and arrived at opposite conclusions about her state of mind. This isn’t unusual, and it isn’t necessarily a sign that one expert is dishonest. Sanity evaluations are retrospective — a psychiatrist is trying to reconstruct someone’s mental state at a specific moment in the past, often based on medical records, interviews conducted much later, and secondhand accounts. Reasonable experts can weigh that evidence differently. This is exactly why an insanity defense so often comes down to which expert the jury finds more credible, not just what the diagnosis on paper says.

Does Texas Have a “Guilty But Mentally Ill” Verdict?

Some states offer juries a middle-ground verdict: guilty, but mentally ill, which results in a prison sentence with mental health treatment built in. Texas does not recognize this category. In Texas, the choice is binary — a defendant is either found guilty in the ordinary sense, or the insanity defense succeeds and the case moves into the civil commitment track described above. There’s no built-in hybrid outcome, which raises the stakes considerably on both sides of an insanity defense in a Texas courtroom.

The Bottom Line for Texas Families Watching This Case

Cases like this one draw attention because they sit at the intersection of criminal law, mental illness, and unbearable loss, and there’s rarely a clean answer that satisfies everyone. What is clear is that Texas has its own detailed framework for handling exactly these questions — one that’s often stricter about proving insanity than people expect, but also far more structured about what happens afterward than the “walks free” narrative that circulates online.

If you or someone you love is facing a serious charge where mental health is part of the picture — whether that’s a question of insanity at the time of the offense or competency to stand trial now — those are two distinct legal issues, and getting the strategy right early matters enormously.
