Background
On the night of May 11, 1987, James Aren Duckett — then the sole patrol officer on duty in Mascotte, Florida — placed eleven-year-old Teresa McAbee in the front seat of his police cruiser. She was never seen alive again. Her body was recovered the following morning from a nearby lake; the medical examiner determined she had been sexually assaulted, strangled, and drowned. Physical evidence, including tire tracks matching Duckett’s patrol car and comingled fingerprints on the car’s hood, implicated him. A jury convicted Duckett of first-degree murder and sexual battery, and the trial court sentenced him to death after finding two aggravating factors: the murder occurred during a sexual battery, and it was especially heinous, atrocious, or cruel.
The Florida Supreme Court affirmed Duckett’s convictions and death sentence in 1990, and he subsequently exhausted multiple rounds of postconviction relief in both state and federal court. In February 2026, Governor Ron DeSantis signed a death warrant scheduling Duckett’s execution for March 31, 2026. This prompted Duckett to seek postconviction DNA testing of a 1987 sperm-head swab from the victim’s underwear — a sample that had not previously been tested because earlier technology would have destroyed it without yielding reliable results. He also filed his fifth successive postconviction motion, raising claims of actual innocence and a Brady violation based on a 2012 Department of Justice letter concerning guilt-phase expert testimony.
The circuit court granted the DNA testing motion but summarily denied the fifth successive postconviction motion before testing was complete. The Florida Supreme Court stayed the execution to allow testing to proceed and later ordered that the full underlying data be provided to Duckett so a statistical analysis could be performed. Both the laboratory (DNA Labs International) and Duckett’s own retained bioinformaticist concluded that the results were inconclusive — the data were insufficient to either include or exclude Duckett as a contributor to the DNA mixture.
The Court’s Holding
The Florida Supreme Court affirmed the circuit court’s summary denial of Duckett’s fifth successive postconviction motion and denied his habeas corpus petition, then lifted the stay of execution. On the due process claim, the court held that whatever procedural concerns may have existed regarding the circuit court’s premature denial of the motion were mooted by subsequent events: the court stayed the execution, ordered disclosure of the full DNA data, and Duckett received and presented his own expert analysis — satisfying the notice-and-opportunity-to-be-heard requirements of due process.
On actual innocence, the court held that Duckett failed to establish a viable newly discovered evidence claim because the DNA results — inconclusive by his own expert’s assessment — could not show a probability of acquittal on retrial when weighed against all trial and postconviction evidence. The court further held that Florida does not recognize a freestanding actual innocence claim in postconviction proceedings and that this rule does not violate the Eighth Amendment, reaffirming its prior precedent on both points.
The court also denied Duckett’s habeas petition, finding that the claims duplicated those raised on appeal and failed for the same reasons. To the extent Duckett sought to relitigate earlier postconviction decisions, those claims were procedurally barred under Florida Rule of Criminal Procedure 3.851(e). The court ordered the mandate to issue immediately and stated no motion for rehearing would be considered.
Key Takeaways
- Inconclusive DNA results — where the defendant’s own expert cannot exclude or include the defendant as a contributor — do not satisfy the “probably produce an acquittal” standard required for a newly discovered evidence claim under Florida postconviction law.
- Florida does not recognize a freestanding actual innocence claim in postconviction proceedings, and the Florida Supreme Court reaffirmed that this rule does not offend the Eighth Amendment.
- Procedural due process in the warrant period is satisfied when the defendant ultimately receives a full and fair opportunity to develop and present evidence, even if earlier steps in the process were imperfect.
- Claims raised in a habeas petition that duplicate claims already adjudicated on appeal are procedurally barred and will be denied on that basis.
Why It Matters
Duckett marks another significant application of Florida’s refusal to recognize freestanding actual innocence claims, a position that diverges from the approach taken by some other jurisdictions and that has drawn ongoing constitutional debate. For capital defense practitioners, the decision underscores the high bar that newly discovered DNA evidence must clear: inconclusive results, even when obtained through cutting-edge technology, will not satisfy the probable-acquittal standard when substantial circumstantial evidence of guilt remains in the record.
The case also illustrates how Florida courts manage the tension between the compressed timeline of warrant proceedings and procedural fairness. The court’s willingness to stay the execution and order disclosure of raw testing data reflects an acknowledgment that meaningful DNA review requires access to underlying data — but the ultimate ruling confirms that once a defendant has had a genuine opportunity to develop and present that evidence, the due process inquiry is satisfied regardless of whether the results proved exculpatory.
