Background
Richard Knight was convicted of the first-degree murders of Odessia Stephens and her four-year-old daughter, Hanessia Mullings, committed on June 27–28, 2000, in Broward County, Florida. The evidence against Knight was extensive: his DNA was found under Stephens’s fingernails, victim blood stained his clothing, law enforcement encountered him wet and injured near the apartment shortly after the killings, and he later confessed in detail to a fellow jail inmate. A jury unanimously recommended death for both murders, and the trial court sentenced Knight accordingly, finding aggravating factors including that each murder constituted a prior violent felony conviction as to the other, both murders were heinous, atrocious, or cruel (HAC), and that Hanessia was under twelve years of age.
Knight’s convictions became final in May 2012 when the U.S. Supreme Court denied certiorari. He subsequently pursued multiple rounds of postconviction review in state and federal courts without success. Governor Ron DeSantis signed a death warrant on April 22, 2026, setting an execution date of May 21, 2026. On May 2, 2026, Knight filed a successive motion for postconviction relief under Florida Rule of Criminal Procedure 3.851, raising three claims: newly discovered evidence based on an unidentified fingerprint, an Eighth Amendment challenge to Florida’s lethal injection procedures, and a due process challenge to the expedited death warrant process.
The circuit court held a Huff hearing on May 5, 2026, and summarily denied all three claims and Knight’s accompanying motions, including a motion to compel additional fingerprint analysis by the Broward County Sheriff’s Office. Knight appealed to the Florida Supreme Court and requested a stay of execution.
The Court’s Holding
The Florida Supreme Court unanimously affirmed the circuit court’s summary denial of postconviction relief and denied Knight’s request for a stay of execution. On the fingerprint claim, the court held that the unidentified print on a knife blade did not constitute newly discovered evidence because it was known to Knight before his 2006 trial, had already been run through the Automated Fingerprint Identification System (AFIS) prior to trial, and was addressed through direct and cross-examination at trial. The court further held that even if the print were newly identified, it would not probably produce an acquittal on retrial given the overwhelming evidence of guilt, including Knight’s detailed confession and extensive forensic evidence linking him to the murders.
On the lethal injection claim, the court rejected Knight’s Eighth Amendment challenge to section 10(i) of the Department of Corrections’ Execution by Lethal Injection Procedures — which addresses the possibility of a venous cut-down procedure — on three independent grounds: the claim was untimely, procedurally barred because Knight had raised lethal injection challenges in prior proceedings, and meritless because Knight’s speculative allegations did not establish a substantial and imminent risk of serious and needless suffering, as required under Glossip v. Gross and Florida precedent. The court also noted that Knight did not allege he would actually be subject to the cut-down procedure.
On the due process claim, the court reaffirmed its consistent rejection of arguments that Florida’s expedited death warrant process unconstitutionally deprives condemned inmates of meaningful collateral review, citing a series of recent decisions reaching the same conclusion. The court found Knight received both notice and an opportunity to be heard, satisfying due process requirements.
Key Takeaways
- An unidentified fingerprint known to the defense before trial and addressed during jury proceedings does not constitute newly discovered evidence capable of supporting a successive postconviction motion, particularly where overwhelming evidence of guilt — including a detailed confession — independently supports the conviction.
- A condemned inmate’s Eighth Amendment challenge to a lethal injection procedure must allege a substantial and virtually certain risk of serious harm and identify a known, available alternative with a significantly lower risk of pain; speculative allegations about a contingency procedure the inmate is not even alleged to face fall far short of this standard.
- Florida’s expedited death warrant litigation schedule does not violate due process where the defendant receives notice and an opportunity to be heard — a conclusion the Florida Supreme Court has now reaffirmed across multiple recent warrant cases.
Why It Matters
This decision illustrates the exceptionally high bar facing death-row inmates who raise successive postconviction claims after exhausting prior state and federal remedies. The court’s treatment of all three claims — on timeliness, procedural bar, and merits grounds — signals that Florida courts will apply rigorous gatekeeping to last-minute challenges filed during the warrant period, particularly where the underlying legal theories have been litigated in earlier proceedings.
The lethal injection ruling also reinforces the demanding Glossip standard as applied to contingency execution procedures. By rejecting a challenge to a cut-down procedure that Knight did not even allege would be used in his execution, the court underscores that hypothetical or speculative risks to a specific inmate will not satisfy the Eighth Amendment threshold required for relief — a holding with potential significance for future challenges to execution protocols in Florida and beyond.
