When the State Seeks Death: The Battle to Prove Intellectual Disability

Imagine facing the ultimate punishment—the death penalty—while battling an intellectual disability that makes it impossible for you to understand the world like everyone else. For decades, the Constitution has protected such individuals from execution.

However, prosecutors often point to a defendant’s ability to drive a car, use a cell phone, or make jail calls as “proof” that they fake their disability. A new ruling from Miami demonstrates that courts must look deeper than surface-level skills.

The Case: State v. Jackson (December 22, 2025)

Reginald Jackson faced indictment for two counts of First-Degree Murder, Armed Robbery, and Kidnapping for the 2013 killings of a woman and her grandson in Miami-Dade County. The State sought the death penalty.

Jackson’s defense team filed a motion to bar the death penalty, arguing that Jackson met the legal definition of “Intellectually Disabled” under Florida Statute § 921.137. What followed became a battle over what “disability” really means.

The Evidence Battle: What the State Claimed vs. What the Defense Proved

The Jackson case illustrates how prosecutors attack intellectual disability claims by focusing on “strengths” while ignoring documented deficits:

The Three-Prong Test for Intellectual Disability in Florida Capital Cases

To save a client from death row in Florida, the defense must prove three specific elements by “clear and convincing evidence”:

Frequently Asked Questions: Intellectual Disability and the Death Penalty

What is the IQ cutoff for the death penalty in Florida?

Generally, an IQ of 70 or below indicates intellectual disability. However, under the U.S. Supreme Court’s Hall v. Florida ruling, courts must apply the “Standard Error of Measurement” (SEM). Consequently, scores slightly above 70 can still qualify. For example, a measured score of 72 might actually represent a true score of 67, qualifying the defendant for protection.

Can a defendant be executed if they are mentally ill?

“Intellectual Disability” (low IQ with adaptive deficits) differs from “Mental Illness” (conditions like schizophrenia or bipolar disorder). While the Constitution bars executing intellectually disabled individuals, severe mental illness typically serves as mitigation evidence to argue for a life sentence rather than an automatic bar to execution. Therefore, establishing intellectual disability provides stronger protection.

How do you prove a disability existed from childhood?

We conduct exhaustive historical investigation. Specifically, we pull birth records (Jackson’s showed a drug-addicted mother), medical records documenting head injuries or developmental delays, and school IEPs. Additionally, we locate former teachers who remember the student’s struggles. This investigation often spans decades and requires significant resources.

What are “adaptive behavior deficits”?

Adaptive behavior refers to the practical skills needed for daily functioning. Courts examine three domains: Conceptual (reading, writing, math, memory); Social (interpersonal skills, empathy, judgment); and Practical (personal care, job responsibilities, money management). Jackson, for instance, could not cook, needed reminders to bathe, and required his grandmother to read his mail as an adult.

What is the “Standard Error of Measurement” (SEM)?

IQ tests have inherent measurement error—no test produces a perfectly precise score. The SEM accounts for this uncertainty. Under Hall v. Florida (2014), the Supreme Court ruled that states cannot use a strict IQ cutoff of 70 without considering the SEM. Consequently, a defendant who scores 72 on a test might have a true IQ of 67, falling within the protected range.

Why do prosecutors focus on “surface skills” like driving or phone use?

Prosecutors attempt to undermine disability claims by highlighting any apparent competence. However, as the Jackson court ruled, the legal standard requires examining deficits, not strengths. Many intellectually disabled individuals can “mask” their disability in short interactions while still lacking the judgment and reasoning required for culpability at the capital level. Performing basic tasks does not negate documented severe deficits.

What is mitigation in a capital case?

Mitigation refers to evidence presented during the penalty phase of a capital trial that argues for a life sentence instead of death. This includes childhood abuse, mental health history, intellectual limitations, trauma, and other factors that explain (not excuse) the defendant’s conduct. Even if a defendant cannot prove intellectual disability under the three-prong test, mitigation evidence can still save their life.

What burden of proof applies to intellectual disability claims?

Florida requires proof by “clear and convincing evidence”—a higher standard than preponderance of the evidence but lower than beyond a reasonable doubt. This means the defense must present evidence that makes the existence of intellectual disability highly probable. Therefore, thorough investigation and expert testimony prove essential.

A confession is supposed to be the most powerful evidence the state can present. When a defendant admits to the crime, most jurors assume the case is closed.

But not all confessions are what they appear to be. Some are coerced. Some are fed to vulnerable suspects by detectives who already believe they have the right person. And some come from children who are mentally ill, isolated, and desperate to make the interrogation stop.

In this case, a forensic psychologist examined the interrogation of a fourteen-year-old boy charged with a sex crime he almost certainly did not commit. What the expert found led to the suppression of the confession—and exposed how easily police can manufacture guilt from a vulnerable child. He exposed a coerced confession in Tampa.

The Case: A Child No One Wanted

My client was a fourteen-year-old boy who had spent his entire life being passed from one caregiver to another. Removed from his biological mother at age two due to abuse of a sibling, he spent years in foster care before being adopted at age six.

But the adoption was never what it should have been. The adoptive mother never bonded with him. She viewed him as a problem to be managed, not a child to be loved. Over the years, she enrolled him in one residential treatment program after another—not because he needed it, but because she did not want him in her home.

Months before the incident, she had hired an attorney to terminate her parental rights. The court denied her request. She told the residential facility that she would rather be arrested for abandonment than take him back into her home. During family therapy sessions, she would read the newspaper when it was his turn to speak.

This was not a mother. This was someone looking for an exit—and she found one.

The Allegation: A Theory Built on Speculation

The boy was home for a weekend visit when the adoptive mother left him alone with an elderly relative who required twenty-four-hour care due to mental incapacity. When the mother returned, she noticed a swelling on the relative’s face.

She took the relative to a walk-in clinic. The doctor examined her, diagnosed an insect bite, and treated her with Benadryl and antibiotics. The doctor found no evidence of intentional trauma.

Later that evening, the mother noticed a small amount of blood on the relative’s diaper. The caregiver noted that the relative had a history of straining during bowel movements, which had caused bleeding in the past.

But the mother had a different theory. On the drive home from church that night, she decided that the boy must have sexually assaulted the relative. She called 911 and reported her speculation as fact.

The Interrogation: A Textbook Case of Coercion

Police arrived at the home, handcuffed the boy, stripped him of his clothing, and transported him to the police station. They placed him in a locked holding cell. Then, close to midnight, two adult detectives brought the fourteen-year-old into a small interrogation room.

What happened next was a textbook case of coercive interrogation:

The child initially denied any wrongdoing. He denied it again and again. But after hours of this treatment—late at night, alone, facing two armed adults who told him they already had proof—he began to agree with whatever the detectives suggested.

That was the “confession.”

The Forensic Psychologist’s Evaluation

I retained a forensic psychologist to evaluate my client and review the videotaped interrogation. The expert conducted multiple clinical interviews and administered standardized psychological testing.

The findings were significant:

• The child had serious mental illness—specifically, Bipolar Disorder with a manic episode at the time of interrogation
• Psychological testing showed markedly elevated scores on mania scales
• Cognitive testing revealed significant impairment in executive functioning
• The child had been in emotionally handicapped classes since kindergarten
• He had no prior criminal record and had never dealt with police or Miranda rights before

The Pattern of a Coerced Confession

The forensic psychologist identified a classic pattern in the interrogation that demonstrated “interrogative suggestibility”—vulnerability to outside influences, pressures, and misinformation:

• Stage 1: The child denies responsibility repeatedly
• Stage 2: When pressed with specific allegations, the child says he “doesn’t remember”
• Stage 3: After prolonged pressure, the child begins agreeing to accusations fed by the detectives

This pattern—denial, then uncertainty, then agreement—is a hallmark of false confessions. The child was not remembering what happened. He was capitulating to what the detectives told him must have happened.

The Legal Standard for Juvenile Confessions

Florida courts apply heightened scrutiny to confessions obtained from juveniles. The state bears a “heavy burden” to demonstrate that a juvenile defendant knowingly and intelligently waived their constitutional rights.

Factors courts consider include:

• How Miranda rights were administered—including any cajoling or trickery
• The suspect’s age, experience, background, and intelligence
• Whether the juvenile was given an opportunity to consult with a parent or guardian
• Where the interrogation took place
• Whether police used threats, promises, or statements calculated to mislead the suspect

In this case, every factor weighed against the state. The child was mentally ill, had never dealt with police before, was interrogated late at night without a supportive adult, and was subjected to deception, false evidence claims, and psychological pressure.

The Critical Flaw: No Guardian to Protect Him

There was one more problem. The adoptive mother—the person who had called police with her speculation, who wanted to terminate her parental rights, who would rather be arrested for abandonment than take the child home—was the only adult consulted about the interrogation.

Her interests were entirely adverse to the child’s. She was not his advocate. She was his accuser.

Under these circumstances, the child should have had a guardian appointed before any questioning. Instead, he faced two armed detectives alone, with no one in his corner.

What This Case Teaches About Challenging Confessions

• A confession is not the end of the case. Even when a defendant has confessed, the voluntariness of that confession can be challenged—especially when the defendant is a juvenile or has mental health issues.
• Forensic psychologists can expose coercion. An expert who reviews the interrogation recording and evaluates the defendant can identify coercive techniques and explain to the court why the confession should not be trusted.
• Juveniles are especially vulnerable. Courts recognize that children are more susceptible to pressure, more likely to comply with authority figures, and less able to understand their rights—which is why juvenile confessions receive heightened scrutiny.
• Mental illness compounds vulnerability. A defendant with serious mental illness may be even less able to resist interrogation pressure or make a knowing, voluntary decision to confess.
• Look for who benefits from the accusation. In this case, the adoptive mother had been trying to get rid of the child for months. Her “theory” gave her exactly what she wanted—and police never questioned her motive.

Frequently Asked Questions

Can a confession be thrown out of court?

Yes. If a confession was not given voluntarily—meaning it was the product of coercion, deception, or exploitation of the defendant’s vulnerabilities—it can be suppressed. The defense must file a motion to suppress and prove that the confession was involuntary under the totality of the circumstances.

What makes a confession involuntary?

Courts consider factors including: whether police made false promises or threats, whether they lied about evidence, whether they exploited the defendant’s mental illness or youth, whether the defendant was deprived of food, water, or sleep, and whether the defendant had access to a supportive adult or attorney.

What is a forensic psychologist?

A forensic psychologist applies psychological expertise to legal questions. They can evaluate defendants, review interrogation recordings, conduct psychological testing, and testify about factors that may have affected the voluntariness of a confession or the defendant’s mental state.

Are juvenile confessions treated differently?

Yes. Florida courts apply heightened scrutiny to juvenile confessions. The state bears a “heavy burden” to prove that a juvenile knowingly and intelligently waived their rights. Factors like age, mental capacity, and experience with the legal system all weigh heavily in the analysis.

Can police lie during interrogations?

Police are generally permitted to use deception during interrogations—but when combined with other coercive factors, lies about evidence can contribute to a finding that a confession was involuntary. This is especially true with juveniles and mentally ill defendants who may be more susceptible to believing false claims.

What if my child confessed but didn’t do it?

False confessions happen more often than people realize—especially with juveniles and individuals with mental illness. A forensic psychologist can evaluate the circumstances of the confession and provide expert testimony on whether it was truly voluntary or the product of coercion.

Was a Confession Coerced?

A confession is only as reliable as the circumstances under which it was obtained. When police use coercion, deception, or psychological pressure—especially against juveniles or individuals with mental illness—the result is not a confession. It is manufactured evidence.
