STORY: "James Duckett: A Case Marked by Unanswered Questions," published by The FADP, on March 9, 2026.
Today, his attorneys argue that the case against him, built entirely on circumstantial evidence, has been undermined by recanted testimony, discredited forensic science, and the possibility of DNA testing that was never presented to the jury who sentenced him to death.
His attorneys argue that modern forensic technology — capable of producing answers that were unattainable in the 1980s — now exists, yet the state is pressing forward with an irreversible punishment while key evidence remains untested and unresolved.
A Case Built on Circumstantial Evidence
The prosecution’s case relied on four main pieces of evidence:
- The testimony of a single witness who claimed she saw the victim leave in Mr. Duckett’s car
- A single pubic hair found on the victim’s clothing that an FBI analyst said was consistent with Mr. Duckett’s
- Tire tracks that allegedly matched his patrol car
- Teresa’s fingerprints found on the hood of his vehicle
No physical evidence conclusively proved that Mr. Duckett committed the crime. The state’s case depended on the jury believing that these pieces of circumstantial evidence pointed to only one possible explanation. Over time, however, each pillar of the prosecution’s case has come under serious challenge.
The State’s Key Witness Later Recanted
The only witness who claimed to see Teresa leave with Mr. Duckett was a woman named Grace Gwendolyn Gurley. Gurley did not come forward until five months after the crime, when she was in jail awaiting sentencing on unrelated charges.
After learning about Mr. Duckett’s arrest from television news coverage, she told a jail officer that she knew him. Investigators soon began visiting her in jail. Records later showed that officers and prosecutors met with her repeatedly and even removed her from the jail on several occasions to take her to meals or visit family members. At trial, Gurley testified that she saw Teresa get into Mr. Duckett’s patrol car. That testimony became the crucial link in the prosecution’s case.
But after the trial, Gurley recanted.
In six separate statements, including sworn testimony, Gurley said the story she told the jury was not true. She stated that investigators had instructed her what to say and told her she would face less jail time if she cooperated. She also said prosecutors took her to the Circle K and showed her where to stand and what to claim she had seen.
According to Gurley, investigators knew the story was false because she told them it was. Her recantation has been corroborated by other witnesses who said Gurley had asked them to lie in order to support her story. Without Gurley’s testimony, the prosecution’s theory that Teresa left with Mr. Duckett collapses.
Discredited Forensic Science
The prosecution also relied heavily on forensic testimony from FBI analyst Michael Malone, who testified that a pubic hair found on Teresa’s clothing was microscopically consistent with Mr. Duckett’s hair.
At trial, prosecutors emphasized this evidence as the most damaging proof against him. But years later, the U.S. Department of Justice reviewed Malone’s work and found serious problems.
The review concluded that Malone repeatedly overstated the reliability of hair comparison analysis and gave scientifically unsupported testimony in many cases. Investigators found that Malone’s work contained serious flaws and that his courtroom statements often exceeded what the science could support.
In Mr. Duckett’s case, the Department of Justice determined that Malone’s testimony included erroneous statements and exaggerated conclusions about the likelihood that the hair came from Mr. Duckett. Subsequent government reports described Malone as one of the most problematic analysts in the FBI laboratory, concluding that he had repeatedly provided scientifically unsupported conclusions in criminal trials.
Even prosecutors have acknowledged that Malone overstated the significance of the hair evidence.
Suppressed Information About the Forensic Evidence
In 2026 — over a week after his execution warrant had already been signed and only after a judge ordered the State to hand over the documents — Mr. Duckett’s attorneys received a previously undisclosed letter showing that the Department of Justice had asked Florida prosecutors in 2012 for information about Malone’s testimony in the case.
The letter indicated that federal officials were concerned that the examiner may have “exceeded the limits of science” when presenting his conclusions. For decades, Mr. Duckett’s lawyers had repeatedly asked the state whether any such correspondence existed. Each time, prosecutors either denied having such information or failed to respond.
The letter only surfaced during the final stages of litigation and was buried in roughly 10,000 pages of new materials.
The Possibility of DNA Evidence
Perhaps the most significant unanswered question in the case involves untested biological evidence that still exists today.
The circuit court recently granted permission for advanced DNA testing known as Single Nucleotide Polymorphism (SNP) testing, a powerful technology capable of identifying contributors to biological evidence with far greater precision than earlier methods. Results are currently pending.
Modern DNA testing could:
- Identify previously unknown contributors to the evidence
- Exclude Mr. Duckett as the source
- Potentially identify the actual perpetrator through genetic genealogy
Identity has always been the central issue in the case. If testing shows that the biological material belongs to someone else, it would directly contradict the prosecution’s theory of the crime. Mr. Duckett’s attorneys believe the results could provide conclusive proof of his innocence.
The Risk of an Irreversible Mistake
Across the United States, DNA testing has exonerated hundreds of people who were once convicted based on faulty forensic science, unreliable witnesses, or investigative errors. Here in Florida, 30 people have already been exonerated from death row.
Those cases have revealed how easily wrongful convictions can occur.
In Mr. Duckett’s case, the prosecution’s key witness recanted. The government has acknowledged that the forensic testimony used at trial was flawed. And biological evidence that could reveal the truth still exists.
Once an execution takes place, the possibility of discovering that truth disappears forever.
For James Duckett, the question is whether the justice system will allow the evidence to be fully examined before carrying out the ultimate punishment."
