NEW: Judge In Lindsay Clancy Trial Issues Major Warning After Jury Intimidation Arrest

The judge overseeing the Lindsay Clancy murder trial opened court Wednesday with a pointed warning after a woman was arrested outside the courthouse on a charge involving alleged intimidation of a witness or juror.

Judge William Sullivan addressed the packed courtroom one day after Massachusetts State Police arrested 56-year-old Dawn Light of Sutton outside the Plymouth courthouse complex, where jurors have been deliberating Clancy’s fate.

“I just want to remind everybody here and elsewhere that there’s been an order that’s been issued in regards to the conducting of this case, as well as statutes in this Commonwealth which relate to jurors, witnesses, attorneys and others,” Sullivan told the courtroom.

He made clear that the court intends to enforce those rules as the high-profile case continues.

Sullivan said the order and statute “is being enforced and will be enforced,” but declined to elaborate, saying he wanted to make the point “with no follow up or editorial comment.”

The judge did not specifically mention Light’s arrest or say whether the incident prompted his warning.

Light was taken into custody around 3:40 p.m. Tuesday, shortly after jurors were dismissed for the day, according to reports.

Massachusetts State Police charged her with one count of intimidation of a witness, juror or person furnishing information in connection with a criminal proceeding.

According to NBC Boston, Light is accused of attempting to photograph members of the jury outside the courthouse.

She was scheduled to be arraigned Wednesday.

State police did not immediately release additional details about the allegations or formally confirm a direct connection to the Clancy proceedings.

It was also not immediately clear whether Light had retained an attorney.

Clancy, 36, a former labor and delivery nurse, has admitted to killing her three children, Cora, 5, Dawson, 3, and Callan, 8 months, on Jan. 24, 2023.

Prosecutors say Clancy strangled the children with exercise bands in the basement of the family’s Duxbury home while her husband was out.

She then slashed her wrists and neck and jumped from a second-story window in an apparent suicide attempt that left her paralyzed from the waist down.

Clancy has pleaded not guilty to three counts of first-degree murder and is arguing that she lacked criminal responsibility because she was suffering from postpartum psychosis and other mental health conditions.

The prosecution has pushed back hard on that defense.

Forensic psychologist Dr. Kirk Heilbrun, called by prosecutors, testified that Lindsay Clancy was criminally responsible for the killings.

Heilbrun focused in part on Clancy’s reported auditory hallucination, which she described as a male voice instructing her to kill the children so she could then kill herself.

He concluded that the account was unusual because Clancy reported hearing the voice only during the killings and testified that she understood the wrongfulness of her actions and had the ability to follow the law.

Prosecutor Jennifer Sprague told jurors during closing arguments that Clancy “knew what she did was wrong. She could conform her behavior to the law, and chose not to.”

Sprague added, “Those kids were her protective factor. Those kids were keeping her from ending her misery, and so she had to remove the protective factor. … But it was a choice.”

The jury of nine women and three men began deliberating Aug. 27 after more than five weeks of testimony featuring more than 80 witnesses and roughly 300 exhibits.

By Tuesday morning, the panel had spent about 23 hours deliberating over four days and sent Sullivan a note revealing that they had reached an impasse.

“After many hours of deliberation, we are unable to come to a unanimous decision.”

Sullivan instructed the jury to continue deliberating given the length and complexity of the trial.

Jurors worked for several more hours before asking to be dismissed around 3:30 p.m. Tuesday.

Possible outcomes include first-degree murder, second-degree murder, manslaughter, not guilty or not guilty by reason of lack of criminal responsibility.

Now, with deliberations already deadlocked once and an arrest involving alleged jury intimidation unfolding outside the courthouse, Sullivan has put everyone connected to the case on notice that interference with the proceedings will not be tolerated.

As of Wednesday morning, the jury had not reached a verdict.
