Background

James Aren Duckett has been on Florida’s death row since 1988 and faces a stayed execution. Following the signing of a death warrant in February 2026, he moved for postconviction DNA testing under section 925.11, Florida Statutes, and Florida Rule of Criminal Procedure 3.853. The physical evidence at issue was a 1987 swab (designated Q-6(3)) taken from the victim’s underwear, which contained a small number of sperm heads. Prior testing attempts had been abandoned because the sample was too degraded for the methods then available. Duckett argued that Single Nucleotide Polymorphism (SNP) technology — capable of analyzing small, deteriorated samples — could now determine whether the sperm was his, potentially exonerating him.

The circuit court granted the DNA testing motion and, because FDLE lacked SNP capability, authorized the State to direct testing to a private laboratory. The State chose DNA Labs International, Inc. (DLI). Testing was completed on March 27, 2026, one day after the Florida Supreme Court stayed the execution. DLI’s Certificate of Analysis reported that the sample yielded DNA from at least one male contributor but was “not suitable for genealogical comparisons or phenotype and ancestry estimations.” FDLE characterized the result as “inconclusive” and acknowledged that neither FDLE nor DLI had the capability to perform the statistical analysis on the raw Y-chromosome SNP data that would be required to draw a meaningful conclusion. FDLE suggested that a qualified bioinformaticist — naming Parabon Nanolabs or Othram, Inc. as possible candidates — might be able to perform that analysis.

Duckett asked the circuit court to compel production of the underlying SNP data so that a bioinformaticist could conduct the statistical analysis. He also filed public records demands seeking the testing data and DLI’s testing process and protocols. After two brief status conferences that permitted no sworn testimony, the circuit court denied both requests, finding that Duckett had failed to show how the information could lead to his exoneration. Duckett appealed to the Florida Supreme Court.

The Court’s Holding

The Florida Supreme Court, in a per curiam opinion joined by six justices, reversed the circuit court’s denial of the underlying DNA testing data and affirmed the denial of the public records demands as to DLI’s testing process and protocols. The court held that the raw SNP data constitutes part of the “results of the DNA testing” that section 925.11(2)(i) requires to be provided to the defendant, the court, and the prosecution. A laboratory’s report of “inconclusive” — issued by an entity lacking the capacity to complete the necessary statistical analysis — does not satisfy the statute’s mandate to deliver complete testing results. Because FDLE itself characterized the Y SNP data as the “results” awaiting further analysis, and because trial admissibility of DNA evidence requires statistical calculations under Florida precedent (see Brim v. State, 695 So. 2d 268 (Fla. 1997)), the court concluded that the underlying data is an integral component of those results.

The court further held that the circuit court erred by imposing an exoneration-based burden on Duckett before releasing the data. Once the court granted the DNA testing motion under section 925.11 and Rule 3.853 — a ruling that required the court to find all statutory prerequisites met — Duckett was entitled to the complete testing results without any further showing. Requiring him to demonstrate prospectively how the statistical analysis would lead to exoneration had no basis in the statute or rule. The court remanded with instructions to provide Duckett the underlying data for bioinformaticist analysis as FDLE directed, and ordered the circuit court to hold an evidentiary hearing if a dispute arose about the scope of data required.

On the public records demands, the court affirmed denial of requests for DLI’s testing process and protocols, finding Duckett had not shown, as Rule 3.852 and Florida precedent require, how that information could relate to a colorable postconviction claim — characterizing the requests as aimed only at potential impeachment evidence, which is insufficient.

Key Takeaways

  • Under section 925.11, Florida Statutes, “results of DNA testing” means the complete underlying data — not merely a private laboratory’s report — when the lab and FDLE both lack the capacity to perform the statistical analysis necessary to make the data interpretable and admissible.
  • Once a circuit court grants a postconviction DNA testing motion, the defendant is entitled to full testing results as a matter of statutory right; courts may not impose a separate, uncodified burden requiring the defendant to demonstrate how the data will lead to exoneration before disclosure.
  • Public records demands in postconviction proceedings under Rule 3.852 require the defendant to show a colorable nexus to a substantive postconviction claim; requests aimed solely at impeaching a testing laboratory’s methods fall short of that standard.
  • Justice Tanenbaum dissented on jurisdictional grounds, arguing that a section 925.11 DNA testing proceeding is a parallel statutory action — not a collateral attack on the judgment — and that orders arising from it are reviewable only in the district courts of appeal, not the Florida Supreme Court.

Why It Matters

This decision clarifies an important procedural gap in Florida’s postconviction DNA testing framework: what happens when a court-ordered test is technically completed but analytically incomplete because the testing laboratory cannot perform all the work the sample’s complexity demands. By holding that “results” encompasses the raw data a bioinformaticist needs to finish the job, the court prevents the postconviction DNA statute from becoming a dead letter in cases involving novel or degraded samples where cutting-edge analysis is split across multiple specialists. Defense attorneys in Florida should take note that they can demand underlying genomic data — not just a laboratory report — as part of the mandatory disclosure obligation.

The case also carries broader significance for death penalty litigation: a majority of the court reaffirmed its longstanding practice of exercising exclusive appellate jurisdiction over all collateral proceedings in capital cases, even those arising from independent statutory actions like DNA testing petitions. Justice Tanenbaum’s sharp solo dissent — arguing that this jurisdictional claim lacks textual support in the Florida Constitution and improperly encroaches on district court authority — signals a live internal debate that may resurface in future capital postconviction cases.
