Background

  • In December 2010 Mia Chay Brown was kidnapped from Johnny Mack Sketo Calhoun’s trailer; her burned car and body were found days later in Geneva County, Alabama. Witnesses saw Calhoun at an Alabama convenience store the morning after with scratches and dried blood; items and DNA linking Brown and Calhoun were recovered from his trailer.
  • Calhoun was convicted of first‑degree murder and kidnapping; jury recommended death (9–3). This Court affirmed on direct appeal, and the U.S. Supreme Court denied certiorari.
  • Calhoun filed a Florida Rule of Criminal Procedure 3.851 postconviction motion; after an evidentiary hearing the circuit court denied guilt‑phase claims but vacated the death sentence for Hurst error and ordered a new penalty phase.
  • Postconviction claims on appeal challenged (inter alia) newly discovered evidence implicating Doug Mixon (testimony from Vermillion and Simmons), multiple ineffective assistance of trial counsel (investigation, experts, witness handling), Brady/Giglio violations, a conflict‑of‑interest claim, motions to amend/reopen, and the court’s use of the State’s written argument in its order.
  • The Supreme Court of Florida affirmed the circuit court’s denial of Calhoun’s guilt‑phase and other postconviction claims and denied his habeas petition asserting ineffective appellate counsel.

Issues

Issue Calhoun's Argument State's Argument Held
Newly discovered evidence implicating Doug Mixon Testimony from Vermillion and Simmons shows Mixon likely killed Brown and entitles Calhoun to a new trial The statements are hearsay or unreliable; even if admissible, they do not overcome the overwhelming evidence against Calhoun Denied — evidence had admissibility/credibility problems and would not probably produce acquittal
IAC — failure to investigate Mixon’s alibi (Contreras) Trial counsel should have interviewed Contreras and used his statements to impeach Mixon Contreras’s statements were false/inadmissible hearsay; counsel’s failure was not deficient or prejudicial Denied — no deficiency or no reasonable probability of different verdict
IAC — failure to retain forensic experts (pathologist; digital forensics) Experts would have undermined State’s timeline and injury inferences Counsel reasonably declined expert testimony as strategic; postconviction experts gave at best cumulative or non‑conclusive opinions Denied — no deficient performance or no prejudice
IAC — handling of multiple trial witnesses Counsel failed to object, investigate, impeach, or cross‑examine key witnesses (12 identified) Many alleged errors were strategic, speculative, or would be cumulative; no reasonable probability of different outcome Denied — strategic decisions and lack of prejudice given overwhelming evidence
Conflict of interest re: Public Defender’s office An attorney in the office knew the victim; entire office was disqualified and Calhoun was deprived of conflict‑free counsel The attorney’s recusal was based on limited personal contact; remaining counsel had no actual conflict Denied — no actual conflict shown under Cuyler; no adverse effect on performance
Brady — suppression of Simmons’ purported report to Sheriff Ward State failed to disclose Simmons’ report implicating Mixon Evidence supports circuit court finding Simmons did not provide the information; nothing was suppressed Denied — failure to satisfy Brady suppression/materiality prongs
Giglio/Napue — false testimony and misleading closing Prosecution knowingly used or did not correct false testimony (Raley; Bradley) and misled jury in closings Testimony was not false; closing argument advanced reasonable inferences from evidence; claims were also procedurally barred Denied — procedurally barred and merits fail (no false testimony; harmless)
Motions to amend/reopen evidentiary hearing & court’s use of State’s written arguments Court abused discretion in denying late amendments/reopen and violated due process by adopting State’s briefing Court gave Calhoun opportunity to present Vermillion, will consider other alleged confessions in pending successive motion; adopting State’s arguments in order did not deny process Denied — no abuse of discretion and no due‑process violation
Habeas — ineffective appellate counsel Appellate counsel omitted challenges (rule‑of‑completeness admission, venue/jurisdiction instructions, victim‑impact testimony) Claims are rehashes of postconviction arguments, procedurally barred or meritless; omitted issues were not reversible/fundamental errors Denied — claims procedurally barred or nonmeritorious; appellate performance not deficient
