TWO PSYCHIATRISTS, TWO COMPLETELY DIFFERENT STORIES: THE BATTLE OVER LINDSAY CLANCY’S STATE OF MIND

One expert says Lindsay Clancy was “clearly psychotic,” trapped in a command hallucination and unable to control her actions. The prosecution’s psychiatrist says she was severely depressed but knew exactly what she was doing. Now jurors must decide which explanation best fits the evidence.

DEDHAM, Mass. — The most consequential question in the Lindsay Clancy trial may no longer be what happened inside the family’s Duxbury home.

The evidence has established the devastating outcome.

The question now is why.

Was Clancy suffering from a severe psychiatric disorder that prevented her from understanding or controlling her actions?

Or was she mentally ill while still capable of distinguishing right from wrong?

That question took center stage as two prominent forensic psychiatrists offered jurors dramatically different interpretations of the same events.

“A VOICE TOLD HER TO DO IT”

Defense expert Dr. Phillip Resnick, a nationally recognized forensic psychiatrist who has consulted on several high-profile criminal cases, testified that Clancy was experiencing postpartum psychosis when she killed her three children.

Resnick said Clancy described hearing a commanding voice telling her to kill.

According to his testimony, the voice became stronger after her husband, Patrick, left the house.

Clancy then took her children — 5-year-old Cora, 3-year-old Dawson and 8-month-old Callan — one at a time to the basement.

She strangled them and, according to the testimony, told each child:

“Go to God.”

Resnick interpreted those words as evidence of a deeply distorted belief system rather than ordinary criminal intent.

THE “PUPPET” THEORY

Resnick described Clancy as being in a dreamlike state during the killings.

He testified that she believed an outside force had taken control of her body — essentially leaving her feeling like a puppet whose actions were being controlled by someone else.

According to Resnick, this was a classic example of a command hallucination.

He said Clancy believed she had no real choice but to obey the voice.

And that belief, he argued, was central to understanding her mental state.

“ALTRUISTIC FILICIDE”

Resnick introduced another important concept to the jury: altruistic filicide.

The term describes a parent killing a child while irrationally believing that the act is somehow being done for the child’s benefit.

According to Resnick, Clancy believed her children would be safer and happier in heaven with her than living without her.

In her distorted mental state, he said, she believed she was protecting them.

Resnick testified that Clancy was suffering from severe depression and Bipolar II disorder, while also experiencing psychosis.

He pointed to her severe suicide attempt following the killings as further evidence that she was profoundly mentally ill.

THEN THE PROSECUTION PRESENTED A VERY DIFFERENT PICTURE

After the defense rested, prosecutors called Dr. Avram Mack as their first rebuttal witness.

Mack agreed on one important point:

Clancy was seriously mentally ill.

He testified that she suffered from major depression and anxiety.

But he rejected the defense’s central conclusion.

Mack said he found no convincing evidence that Clancy was psychotic when she killed her children.

He also found no evidence of mania or hypomania.

And that distinction could be critical.

Because under Massachusetts law, severe mental illness does not automatically mean a defendant is legally incapable of being held responsible for a crime.

“METHODICAL” — ONE CHILD AT A TIME

Mack described the killings very differently from Resnick.

Rather than seeing an uncontrolled psychotic episode, he described the actions as organized and methodical.

Clancy, he said, went through the process one child at a time.

Mack argued that this demonstrated goal-directed behavior.

In his assessment, Clancy was capable of organizing her actions and understanding what she was doing.

He also told jurors that she retained the ability to distinguish right from wrong.

WHAT ABOUT THE STRANGE THOUGHTS?

One particularly unusual moment became part of Mack’s analysis.

Clancy reportedly asked her mother:

“Can you hear my thoughts?”

At first glance, the question might sound like evidence of psychosis.

But Mack interpreted it differently.

He told jurors that the question could actually demonstrate reality testing.

In other words, Clancy was questioning whether her thoughts could be heard rather than firmly believing that other people could literally hear them.

That distinction became part of Mack’s argument that she was not experiencing a psychotic break at the time of the killings.

MACK ALSO QUESTIONED CLANCY’S ACCOUNT

Mack pointed to discrepancies between statements Clancy made and other evidence in the case.

Among the issues he discussed were questions surrounding whether a bedroom door had been locked, whether a window screen had been cut before Clancy exited the house and what the children were doing before Patrick left.

For Mack, those inconsistencies mattered because they affected his assessment of Clancy’s reliability and mental state.

He argued that the broader sequence of events showed planning and purposeful behavior rather than an individual completely disconnected from reality.

WHAT DID “GO TO GOD” MEAN?

The words Clancy allegedly spoke to her children became another major point of disagreement.

Resnick viewed the statement through the lens of altruistic filicide — a belief that the children were being taken somewhere better.

Mack reached a very different conclusion.

He argued that saying “Go to God” demonstrated that Clancy understood her children were innocent and recognized the moral significance of what she was doing.

For the prosecution’s expert, the statement was therefore evidence of awareness rather than proof of psychosis.

THE DEFENSE ATTACKS MACK’S EXPERIENCE

Defense attorney Kevin Reddington challenged Mack aggressively during cross-examination.

One major issue was Mack’s experience treating postpartum psychosis.

Mack estimated that he had treated approximately 10 women with postpartum psychosis since 2001.

Reddington questioned whether that experience was sufficient to support Mack’s conclusions about Clancy.

The defense also highlighted the fact that postpartum psychosis is not a separate diagnosis in the DSM-5, instead being associated with other psychiatric conditions.

Reddington challenged Mack’s interpretation of Clancy’s medical history and his conclusions about her symptoms.

TWO EXPERTS. ONE NIGHT. OPPOSITE CONCLUSIONS.

The testimony has now left jurors with two radically different interpretations.

DR. PHILLIP RESNICK’S THEORY:

Clancy was:

• Severely depressed
• Suffering from Bipolar II disorder
• Experiencing postpartum psychosis
• Hearing a command hallucination
• Convinced an outside force was controlling her
• Unable to resist the command to kill
• Acting under a distorted belief that her children would be better off in heaven

DR. AVRAM MACK’S THEORY:

Clancy was:

• Severely depressed
• Suffering from anxiety
• Not psychotic
• Capable of reality testing
• Capable of organizing her behavior
• Capable of understanding right from wrong
• Capable of following the law

And that difference could ultimately determine the legal outcome.

THE QUESTION JURORS MUST NOW CONFRONT

Nobody in the courtroom is disputing that Clancy was experiencing serious psychological problems.

The disagreement is about something far more specific:

Did those problems destroy her ability to understand the nature and wrongfulness of what she was doing?

The defense says yes.

The prosecution says no.

One psychiatrist sees a woman whose mind had been overtaken by psychosis.

The other sees a severely depressed woman who nevertheless remained connected to reality and capable of making purposeful decisions.

THE FINAL BATTLE MAY COME DOWN TO THE TIMELINE

That is why the hours surrounding Patrick Clancy’s departure have become so important.

What did Lindsay do after he left?

What did she say?

How did she behave?

What evidence shows planning?

What evidence suggests psychosis?

And how should jurors interpret the statements and actions that followed?

Those questions are now at the heart of the trial.

The defense says Clancy’s mind had effectively turned against reality.

The prosecution says the evidence shows something different — a deliberate sequence of actions carried out by a woman who understood what she was doing.

THE JURY’S DECISION WILL REST ON MORE THAN ONE EXPERT

Neither psychiatrist’s testimony automatically determines the verdict.

Jurors will have to weigh the competing expert opinions against the physical evidence, witness testimony, medical records, Clancy’s statements and the entire timeline presented during the trial.

And they will ultimately have to decide which explanation is supported by the evidence beyond the applicable legal standard.

For now, the courtroom has been given two dramatically different versions of the same tragedy.

A mother hearing a voice she believed she could not disobey.

Or a mentally ill woman who still understood the difference between right and wrong.

The jury must decide which account fits the evidence.

And that decision could determine whether Lindsay Clancy is found legally responsible for the deaths of her three children — Cora, Dawson and Callan.

Testimony is expected to resume Monday.
