Lindsay Clancy Trial Judge Considers ‘Involuntary Intoxication’ Jury Instruction

A major legal battle emerged during Day 17 of the Lindsay Clancy trial as the judge considered whether jurors should be allowed to hear an instruction on “involuntary intoxication” when they eventually deliberate over Clancy’s criminal responsibility.

The issue became important because the defense argues that prescription medications, changes in dosage, side effects and the abrupt stopping of certain medications may have significantly affected Clancy’s mental state before the deaths of her three children.

During a preliminary discussion about jury instructions, Judge William Sullivan asked both sides what instructions they wanted the jury to receive.

The Commonwealth requested instructions covering first-degree and second-degree murder. For first-degree murder, prosecutors said they intended to rely on two theories: deliberate premeditation and extreme atrocity or cruelty.

The prosecution also requested instructions concerning prior consistent and inconsistent statements, opinion testimony, redactions, stipulations and consciousness of guilt.

But the biggest disagreement centered on intoxication.

The Commonwealth argued that the jury should not receive an intoxication instruction because, in its view, there was not enough evidence that Lindsay was intoxicated by drugs or alcohol at the time of the killings.

Prosecutors pointed to the medications Clancy was taking around January 24, 2023. They described them as relatively low-dose prescription medications, including amitriptyline, trazodone and Valium.

The prosecution also noted that there was testimony suggesting Clancy had taken pills after killing the children. However, prosecutors argued that toxicology showed only low levels of those substances.

The judge then raised an important legal question.

He asked the Commonwealth to clarify what should legally qualify as intoxication. If someone takes prescription medication as directed and experiences some effects from it, would that alone be enough to justify an intoxication instruction?

The prosecutor argued that simply taking medication as prescribed should not automatically be considered intoxication.

Instead, the Commonwealth suggested that intoxication would generally involve taking a substance in excess, combining substances, or reaching a level where the person’s ability to think, act or control their behavior is impaired.

That interpretation became the central point of disagreement.

Defense attorney Kevin Reddington strongly rejected the Commonwealth’s position.

He argued that the evidence presented throughout the trial clearly supported an involuntary intoxication defense.

According to the defense, the issue was not illegal drugs or alcohol. Instead, the focus was on prescription medications and the possible consequences of how those medications were prescribed, adjusted and discontinued.

Reddington pointed to several factors that he said could have contributed to Clancy’s mental state.

Those included what the defense characterized as excessive medication, possible side effects, changes in dosage, the titration of medications, and the stopping of medications in ways the defense argues may have conflicted with normal medical advice.

He also pointed to Clancy’s reported experiences with benzodiazepines and her concerns that she was becoming dependent on them.

The defense argued that Clancy had repeatedly described being affected by the medications and had expressed concerns about trying to stop taking them.

Reddington also referenced Clancy’s experience with sertraline, claiming that she had described the medication as having a severe effect on her when the dosage was increased.

From the defense perspective, these circumstances could be relevant to whether Clancy was capable of forming the mental state required for the charged offenses.

The defense therefore asked Judge Sullivan to allow the jury to consider involuntary intoxication as part of its assessment of criminal responsibility.

But the Commonwealth pushed back.

Prosecutors emphasized that many of the medications highlighted by the defense were taken before Clancy’s hospitalization at McLean Hospital.

According to the prosecution, Clancy had been weaned off Seroquel while at McLean and had been off those earlier medications for approximately three weeks by the time of the January 24, 2023 incident.

The Commonwealth argued that this distinction was critical.

The prosecution essentially told the court that what mattered was not how Clancy had reacted to medications months earlier, but what medications she was taking and how they affected her on the day the children died.

The prosecutor compared the issue to an operating-under-the-influence case.

Being intoxicated months earlier, the Commonwealth argued, would not establish intoxication on the date of the alleged offense. The relevant question would be the defendant’s condition at the time of the incident.

The judge appeared to recognize that distinction and summarized the Commonwealth’s position: the relevant analysis should focus on what Clancy was taking on or around January 24, 2023.

The defense, however, sought to place the medication history into a much broader context.

Reddington argued that the jury should not be forced to examine Clancy’s state of mind in isolation. He said the history of medication changes, side effects and withdrawal could help explain what happened on the day of the deaths.

The defense also requested that the jury receive an instruction on involuntary manslaughter as a lesser offense.

The Commonwealth objected to that request.

Prosecutors argued that the evidence showed a specific intent to cause death, making an involuntary manslaughter instruction inappropriate.

The defense also asked the court to consider an instruction concerning wanton conduct and the possible impact of intoxication.

The judge did not make a final ruling during this preliminary discussion.

Instead, he explained that he would prepare a rough draft of the jury instructions and provide it to the attorneys. The lawyers would then have an opportunity to review the proposed instructions and raise objections or suggest changes before the final charge conference.

Another issue arose over whether the jury should receive a simplified chart listing the elements of the various murder theories.

The defense opposed the idea.

Reddington argued that a checklist could oversimplify a complicated murder case and potentially encourage jurors to treat the deliberation process like a list of boxes to check.

He specifically objected to a chart identifying elements such as deliberate premeditation, malice and extreme atrocity or cruelty.

Judge Sullivan indicated that he generally does not use such a chart.

However, he said his normal practice is to provide every juror with a full copy of the jury instructions. That would allow them to follow along while he explains the law, particularly because the instructions are lengthy and complex.

No final decision was announced during the hearing about whether the jury would ultimately receive an involuntary intoxication instruction.

The court also discussed the trial schedule.

The defense was expected to present Dr. Resnick next, followed by several medical experts for the Commonwealth. The judge said the evidence might be completed by Friday, although it could extend into Monday.

Closing arguments were tentatively expected for Monday or Tuesday, depending on how quickly the remaining testimony was completed.

The significance of the discussion goes far beyond a technical question about jury instructions.

At the heart of the defense strategy is the argument that Lindsay Clancy’s mental state may have been affected by prescription medications and the complicated history of changing, increasing and discontinuing those medications.

The prosecution, meanwhile, is attempting to keep the focus tightly on Clancy’s condition at the time of the killings and argues that earlier medication problems do not automatically establish intoxication on January 24, 2023.

The judge’s eventual decision could therefore shape how jurors are permitted to evaluate one of the defense’s most important arguments: whether medication-related effects contributed to Clancy’s ability—or inability—to understand and control her actions when the tragedy occurred.
