Background

  • Truehill and two accomplices escaped a Louisiana prison, committed a multi-state crime spree, and kidnapped and brutally murdered Vincent Binder; extensive physical and circumstantial evidence (ATM footage, use of Binder’s bankcard, items and blood matching Binder found in the stolen truck and motel rooms) tied Truehill to the crimes.
  • At trial Truehill was convicted of first-degree murder and kidnapping; jury unanimously recommended death; trial court found aggravators outweighed mitigators and imposed death.
  • Truehill’s direct appeal was previously affirmed in Truehill v. State, 211 So. 3d 930.
  • Truehill filed a timely Rule 3.851 postconviction motion raising multiple ineffective-assistance, Giglio, newly discovered evidence (MIX13), and other claims; the circuit court held an evidentiary hearing and denied relief in full.
  • Truehill also filed a habeas petition alleging ineffective appellate counsel and requesting proportionality review; the Florida Supreme Court denied postconviction relief and the habeas petition, affirming the circuit court.

Issues

Issue Plaintiff's Argument Defendant's Argument Held
Voir dire/ juror questioning Counsel failed to ask about racial bias, death-penalty views, or ability to consider mitigation Counsel employed reasonable strategy, asked panel collectively, avoided potentially damaging direct race questions Denied — no deficient performance
Failure to object to prosecutor statements Counsel didn't object to allegedly improper opening/closing (unsupported factual assertions, "hatchet man") Opening is not evidence; characterizations were fair comments tied to record Denied — no deficient performance
Handling of witnesses (guilt & penalty phases) Counsel failed to impeach or prepare several witnesses (misidentifications, preparation) Strategic reasons (avoid dramatic reidentification; corroborating DNA/evidence) made choices reasonable Denied — no deficient performance
DNA-related ineffective assistance Counsel failed to obtain FDLE/SWGDAM docs, challenge low-level mixed DNA, or object to Livingston’s methodology Even if deficient, overwhelming non-DNA evidence (ATM, bankcard use, physical items, full-profile matches) defeats prejudice Denied — no prejudice shown
Giglio claims re: DNA expert Livingston Livingston omitted disclosure about guideline changes and statistical weights, rendering testimony false/material No specific false testimony shown; absence of testimony not a Giglio violation; materially immaterial given other evidence Denied — no Giglio violation
Newly discovered evidence (MIX13 studies) MIX13 shows inconsistency in DNA interpretation that would undermine mixed-sample evidence Counsel knew of interpretation issues; studies not "new" or would not probably produce acquittal Denied — fails Jones test/no probable acquittal
Summary denials (venue, jury cross-section/voting restrictions, proportionality) These claims required evidentiary hearings Claims procedurally barred, legally insufficient, or based on co-defendant plea/deal reasons unrelated to Truehill Denied — summary denial affirmed
Habeas: ineffective appellate counsel & proportionality Appellate counsel failed to expressly raise federal claims; comparative proportionality warranted given co-defendants’ life sentences Appellate briefs presented substance of federal claims; exhaustion preserved; proportionality review not required Denied — no deficient appellate performance; proportionality claim denied
