187 So. 3d 822
Fla.2015Background
- Michael T. Rivera was convicted of first-degree murder (death sentence) for the 1986 abduction and killing of 11‑year‑old Staci Jazvac; conviction rested on jailhouse confessions, victimology evidence, and other inculpatory testimony. Rivera I affirmed conviction and sentencing.
- Multiple prior postconviction proceedings occurred; this appeal challenges denial of a successive Rule 3.850 motion remanded for evidentiary hearing.
- Successive motion pressed three principal claims: (1) newly discovered DNA showing a hair in a van did not come from the victim; (2) Giglio claim that jailhouse informant Frank Zuccarello falsely testified he received no deal; and (3) Brady/ineffective‑assistance claims alleging the State withheld documents showing Zuccarello was a confidential informant or received benefits.
- At the evidentiary hearing the defense produced plea paperwork, jail receipts, reports referring to Zuccarello as a CI, and polygraph/affidavit materials; the State and witnesses (including Zuccarello’s counsel and prosecutors) testified that the plea related to other crimes (e.g., Cohen homicide), did not contemplate testimony in the Rivera case, and that some CI labels were used for brevity.
- The postconviction court ruled many claims procedurally barred for lack of due diligence, and on the merits found no Giglio/Brady violation and that the DNA results were not sufficiently exculpatory to probably produce an acquittal. The Supreme Court of Florida affirmed.
Issues
| Issue | Plaintiff's Argument | Defendant's Argument | Held |
|---|---|---|---|
| Procedural bar / Due diligence for successive 3.850 claims | Rivera: documents (plea, receipts, CI reports, Rios report) were not known/produced earlier despite diligence, so successive claims are timely | State: records and correspondence show disclosure or that counsel could have discovered material with reasonable diligence | Court: Rivera failed to prove due diligence as to the documents; claims are procedurally barred (review of facts for substantial evidence) |
| Giglio (false/uncorrected testimony re: plea/CI status) | Rivera: Zuccarello falsely denied a deal and was a State agent/CI whose benefits were concealed | State: plea dealt with other crimes; prosecutors and Zuccarello's counsel testified the plea did not cover testimony in Rivera’s case; CI labels were used for brevity | Court: competent evidence supports that plea did not cover Rivera testimony and Zuccarello was not a CI for this case; Giglio claim fails |
| Brady (suppression of impeachment/exculpatory evidence) | Rivera: withheld documents showing Zuccarello’s relationship with law enforcement and jail benefits were Brady material | State: impeachment evidence (plea, motive) was explored at trial; many documents cumulative or equally available; some referenced only later | Court: even if disclosed, documents would be cumulative to impeachment presented at trial; not material under Brady; claim fails |
| Newly discovered DNA (hair in van not victim’s) | Rivera: DNA exclusion of hair in van undermines State’s case and, with other evidence, establishes reasonable doubt | State: hair comparison was already admitted as non‑definitive; other strong inculpatory evidence (confessions, pattern of offenses) persists | Court: DNA result is newly discovered but not of such nature that it would probably produce an acquittal; conviction stands |
