TWO PSYCHIATRISTS, TWO VERY DIFFERENT STORIES: WHAT WAS HAPPENING INSIDE LINDSAY CLANCY’S MIND?

The Lindsay Clancy trial has reached a critical point, with two psychiatric experts offering jurors dramatically different explanations for the night her three children — Cora, Dawson and Callan — were killed.

DEDHAM, Mass. — The central question in Lindsay Clancy’s trial has increasingly moved beyond what happened inside the family’s home.

Now, jurors are being asked to consider something much harder to see: what was happening inside Clancy’s mind at the time?

Was she experiencing a severe psychotic episode, hearing a commanding voice and believing she had no control over her actions?

Or was she suffering from serious depression and anxiety while remaining capable of understanding right from wrong?

Two forensic psychiatrists have now given the jury strikingly different answers.

THE DEFENSE EXPERT: “CLEARLY PSYCHOTIC”

The defense’s final witness, renowned forensic psychiatrist Dr. Phillip Resnick, testified that Clancy was suffering from severe depression, Bipolar II disorder and psychosis when her children were killed.

Resnick said Clancy described hearing a loud voice that commanded her to kill after her husband, Patrick, left the home.

According to testimony, Clancy took her children into the basement one at a time and strangled them.

She then told each child:

“Go to God.”

For Resnick, those words had to be understood within the context of what he described as a profound psychiatric crisis.

A “COMMAND HALLUCINATION”

Resnick testified that Clancy experienced what is known as a command hallucination — a perceived voice giving instructions that the person feels compelled to follow.

He described Clancy as believing an outside force had taken control of her body.

His testimony portrayed her as being in an almost dreamlike state, feeling like a puppet with someone else controlling the strings.

Resnick told jurors that Clancy was “clearly psychotic” on the day of the killings.

He argued that her psychosis prevented her from controlling her actions when she believed the voice was commanding her.

WHY RESNICK CALLED IT “ALTRUISTIC FILICIDE”

Resnick went further, describing the case as “altruistic filicide.”

The term refers to 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 better off in heaven with her than continuing to live without their mother.

In that distorted state of mind, he said, she believed she was acting out of love rather than committing an act she understood as morally wrong.

Resnick also pointed to Clancy’s severe suicide attempt after the killings as additional evidence of the depth of her psychiatric crisis.

THEN THE PROSECUTION PRESENTED A VERY DIFFERENT THEORY

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

Mack agreed that Clancy was experiencing serious mental-health problems.

But he rejected the defense’s central conclusion.

He testified that Clancy suffered from major depression and anxiety, but he found no evidence of mania, hypomania or psychosis when she killed her children.

Instead, Mack described the killings as “methodical.”

That word became particularly important because it went directly against the defense’s portrayal of Clancy as someone whose behavior was controlled by psychosis.

MACK: SHE COULD STILL UNDERSTAND RIGHT FROM WRONG

Mack told jurors that Clancy retained the ability to understand what she was doing was wrong.

He also testified that she remained capable of following the law.

In his assessment, her behavior throughout the day demonstrated an ability to function, make decisions and organize her actions.

Mack described the killings as an organized, one-by-one effort to accomplish a goal.

For prosecutors, that testimony supports the argument that Clancy’s mental illness did not eliminate her ability to understand the consequences of her actions.

WHAT ABOUT “CAN YOU HEAR MY THOUGHTS?”

Mack also addressed some of the unusual statements attributed to Clancy.

At one point, she reportedly asked her mother:

“Can you hear my thoughts?”

The defense has argued that statements like this were evidence of psychosis.

Mack interpreted the statement differently.

He said the question could actually demonstrate reality testing — the ability to question whether a belief is true rather than accepting it as fact.

In Mack’s interpretation, Clancy was asking whether her mother could hear her thoughts rather than firmly believing that she could.

That distinction became another major point of disagreement between the psychiatric experts.

DISCREPANCIES ALSO RAISED QUESTIONS

Mack pointed to inconsistencies between Clancy’s statements and other evidence.

He discussed questions surrounding whether she locked a bedroom door, whether she cut the window screen before leaving through the window and what the children were doing before Patrick left the house.

Mack said those discrepancies were relevant when evaluating Clancy’s account and mental state.

The prosecution’s expert argued that the overall sequence of events showed purposeful behavior rather than someone completely detached from reality.

WHAT DID “GO TO GOD” REVEAL?

Even Clancy’s words to her children became part of the psychiatric debate.

Resnick viewed the statement through the concept of altruistic filicide — a mother believing her children were being taken somewhere better.

Mack reached the opposite conclusion.

He testified that the words could indicate Clancy understood that her children were innocent and recognized the significance of what was happening to them.

In his view, that suggested awareness rather than psychosis.

THE DEFENSE CHALLENGES MACK

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

One focus was Mack’s experience treating postpartum psychosis.

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

Reddington questioned how much that experience should influence Mack’s conclusions about Clancy.

The defense also emphasized that postpartum psychosis is not currently a standalone diagnosis in the DSM-5, and Reddington challenged Mack’s interpretation of Clancy’s medical history.

TWO EXPERTS — OPPOSITE CONCLUSIONS

The competing testimony has now given jurors two dramatically different explanations.

RESNICK’S VIEW

Clancy was:

• Severely depressed
• Suffering from Bipolar II disorder
• Experiencing psychosis
• Hearing a commanding voice
• Convinced an outside force controlled her
• Unable to resist the command
• Acting under the belief that her children would be better off in heaven

MACK’S VIEW

Clancy was:

• Suffering from major depression and anxiety
• Not experiencing psychosis
• Capable of reality testing
• Capable of organizing her behavior
• Capable of understanding right from wrong
• Capable of following the law
• Acting in a methodical and purposeful manner

THE QUESTION THAT COULD DEFINE THE VERDICT

The dispute is not simply whether Clancy was mentally ill.

Both experts agreed she was experiencing significant psychological problems.

The critical issue is whether her mental condition was so severe that it prevented her from understanding the nature or wrongfulness of her actions.

The defense says yes.

The prosecution says no.

And that distinction could be decisive.

NOW THE JURY MUST WEIGH THE EVIDENCE

Jurors will ultimately have to evaluate the psychiatric testimony alongside the physical evidence, witness accounts, medical history, statements attributed to Clancy and the timeline of events.

Neither psychiatrist gets to decide the case.

The jury does.

And they have now heard two fundamentally different pictures of the same night.

One portrays Lindsay Clancy as a severely ill mother whose mind had been overtaken by psychosis and a voice she believed she had to obey.

The other portrays a deeply depressed woman who was nevertheless connected enough to reality to organize her actions and understand that what she was doing was wrong.

The courtroom now faces a question that cannot be answered simply by looking at what happened.

The jury must decide what Clancy understood — and whether her mental illness changed her legal responsibility for the deaths of Cora, Dawson and Callan.
