Background
In 1992, a jury convicted Gary Richard Whitton of the robbery and first-degree murder of James Mauldin in Walton County, Florida, and recommended a death sentence, which the trial court imposed. The conviction rested in part on testimony from two jailhouse cellmates: Kenneth McCullough, who said Whitton confessed to him, and Jake Ozio, who claimed to have overheard that confession. After the Florida Supreme Court affirmed on direct appeal and the U.S. Supreme Court denied certiorari in 1995, Whitton mounted a series of unsuccessful postconviction challenges in state court over the following three decades.
During Whitton’s initial postconviction proceeding, he alleged that Ozio had testified falsely and that the State knew it, raising claims under Giglio v. United States and Brady v. Maryland. The Florida Supreme Court rejected those claims in 2014, finding Whitton had not shown the testimony was false or that the State was aware of any falsity. Ozio declined to testify at the postconviction evidentiary hearing after being advised by independent counsel of his perjury exposure.
Whitton also pursued federal habeas relief. In a May 2021 deposition and at a September 2022 federal evidentiary hearing, Ozio recanted his trial testimony, admitting he never actually overheard a confession, believed he would receive a benefit for testifying, and lied about his prior criminal record—while acknowledging he had no evidence the State knew his testimony was false. Both the federal district court and the Eleventh Circuit denied relief. The U.S. Supreme Court vacated and remanded on a separate evidentiary issue in June 2026. Meanwhile, on July 7, 2023, Whitton filed in state court the second successive postconviction motion at issue here, claiming Ozio’s federal testimony constituted newly discovered evidence of prosecutorial misconduct.
The Court’s Holding
The Florida Supreme Court unanimously affirmed the circuit court’s summary denial of Whitton’s second successive postconviction motion, agreeing that all three claims—newly discovered evidence of false testimony, a Giglio violation, and a Brady violation—were both untimely and procedurally barred. Writing for the Court, Justice Couriel held that Whitton’s Ozio-related claims became discoverable through due diligence no later than 2000, when Whitton obtained Ozio’s recantation affidavit, and at the very latest by May 17, 2021, the date of Ozio’s federal deposition. Because Whitton did not file his motion until July 7, 2023—more than two years after the deposition—it was untimely under the one-year limitations period of Florida Rule of Criminal Procedure 3.851(d).
The Court also rejected Whitton’s argument that the limitations clock should have started running in September 2022 when Ozio testified at the federal evidentiary hearing, reaffirming that the timeliness inquiry focuses on when evidence became discoverable through due diligence, not on when it was later presented in court. The Court further held that the claims were independently barred as relitigation of issues already rejected in prior postconviction proceedings, and that offering new factual support for old claims does not overcome a procedural bar.
The Court addressed Whitton’s contention that the State “threatened” Ozio into silence at the initial postconviction hearing. Applying Johnson v. State, the Court found no improper threat: the State had merely informed Ozio of his perjury exposure, after which Ozio, advised by independent counsel, chose not to testify. Although the circuit court erred in skipping the case management conference required by rule 3.851(f)(5)(B), the Court found that error harmless because the motion lacked merit.
Key Takeaways
- Previously known evidence does not become “newly discovered” each time a witness repeats or elaborates on it in a new proceeding; the one-year clock runs from when the underlying information was first discoverable through due diligence.
- A defendant cannot overcome a procedural bar on a successive postconviction claim simply by marshaling new evidentiary support for a claim that was previously raised and rejected.
- Informing a witness of potential perjury liability—without more—does not constitute a prosecutorial “threat” that excuses a capital defendant’s failure to develop claims in earlier proceedings.
- Failure to hold a Huff case management conference on a successive postconviction motion is harmless error when the motion is legally insufficient on its face.
Why It Matters
This decision reinforces the Florida Supreme Court’s strict enforcement of timeliness and procedural-bar rules in capital postconviction litigation. By holding that a recanting witness known to the defense for over two decades cannot generate a fresh limitations period simply by testifying in a subsequent federal proceeding, the Court closes a potential avenue through which death-row inmates might indefinitely extend state collateral review by pointing to federal habeas developments as “new” evidence.
The ruling also clarifies the boundary between legitimate prosecutorial advice and improper witness intimidation in the postconviction context, signaling that advising a witness of perjury risk—when the witness then consults independent counsel—will not be treated as state interference that tolls procedural bars. For capital defense practitioners, the case underscores the importance of aggressively developing and presenting recantation evidence at the earliest possible stage of postconviction proceedings.
