Summary
The Supreme Court of Florida addresses consolidated proceedings involving Thomas Mitchell Overton's motion for postconviction relief, request for postconviction DNA testing, and petition for a writ of habeas corpus. The court considers claims concerning the fairness of the postconviction evidentiary hearing and ineffective assistance of trial counsel, including counsel's participation in a Frye hearing involving DNA evidence. The opinion ultimately evaluates the procedural bars, merits, and alleged prejudice associated with Overton's claims.

Questions Presented
- Whether Overton was denied a full and fair evidentiary hearing during Rule 3.851 proceedings.
- Whether trial counsel was ineffective in connection with the Frye hearing, DNA evidence, jailhouse informants, alibi and alternative theories, the burglary charge, preindictment delay, and an alleged conflict of interest.
- Whether the State violated Brady by withholding investigative notes, evidence concerning DNA examiner conduct, information about other suspects, or missing police-report pages.
- Whether the trial court improperly summarily denied several Rule 3.851 claims.
- Whether the trial court properly denied DNA testing of hairs attached to tape used to bind the victim.
- Whether Overton was entitled to habeas relief based on ineffective assistance of appellate counsel concerning venue, DNA evidence, and Ring and Apprendi challenges.
Holdings
- Overton was not denied a full and fair evidentiary hearing. Claims concerning alleged judicial misconduct were procedurally barred because no contemporaneous objection or motion to disqualify was made, and the remaining complaints lacked merit.
- Trial counsel was not ineffective for limiting participation in the Frye hearing or for failing to obtain additional DNA-related relief because the decisions were reasonable strategic choices and Overton failed to establish deficient performance or prejudice.
- The DNA evidence was properly admitted because the chain of custody was intact, and even a break in the chain would not alone establish probable tampering requiring exclusion.
- Overton failed to establish ineffective assistance based on counsel's handling of jailhouse informants, an incomplete work alibi, alternative theories, the burglary statute of limitations, preindictment delay, or an alleged conflict of interest.
- Overton failed to establish Brady violations because the alleged materials were speculative, cumulative, undisclosed only in conclusory terms, immaterial, or not favorable to him.
- The trial court properly denied testing under Rule 3.853 because the requested results would not likely be admissible or create a reasonable probability of acquittal or a lesser sentence.
- Appellate counsel was not ineffective for failing to challenge the denial of a change of venue, the admission of DNA evidence, or Florida's capital-sentencing scheme under Ring and Apprendi.
Key quotations
“Relevant physical evidence is admissible unless there is an indication of probable tampering.” (976 So. 2d at 553)
“This assertion is the type of speculation that this Court has found to be a basis for denying a rule 3.853 motion.” (976 So. 2d at 569)
Factual background
Overton was convicted of murdering Susan and Michael MacIvor, killing their viable unborn child, sexually battering Susan, and burglarizing the MacIvor home. DNA testing performed by FDLE using RFLP analysis and by Bode Technology using STR analysis matched Overton to biological evidence recovered from the crime scene. Overton later sought postconviction relief based principally on ineffective assistance, alleged Brady and Giglio violations, preindictment delay, DNA-testing issues, and challenges to his death sentences. He also sought DNA testing of hairs attached to tape used to bind Susan, arguing that testing might identify another perpetrator.
Procedural history
Overton was convicted of two first-degree murders and related offenses and received two death sentences. The Supreme Court of Florida affirmed the convictions and sentences on direct appeal in Overton v. State, 801 So. 2d 877 (Fla. 2001). The trial court denied Overton's Rule 3.851 postconviction motion, partially denied his first DNA-testing motion, denied his second DNA-testing motion concerning hairs attached to tape used to bind a victim, and Overton petitioned the Supreme Court of Florida for habeas relief. The Supreme Court affirmed the postconviction rulings and denied habeas relief.
