311 So.3d 613
Miss. Ct. App.2020Background
- In May 1997 two‑year‑old Bryan Thompson IV died of massive brain swelling and intracranial hemorrhage; Dr. Leroy Riddick’s 1997 autopsy listed cause of death as blunt‑force trauma and manner homicide.
- Tasha Shelby, the sole adult at home when Bryan was found unresponsive, was tried (2000), convicted of capital felony murder, and sentenced to life without parole; this Court affirmed her conviction on direct appeal.
- In 2015 Shelby sought post‑conviction relief (PCR) claiming “newly discovered evidence”: Dr. Riddick had changed his opinion and newer literature questioned the shaken‑baby/abusive‑head‑trauma (SBS/AHT) paradigm.
- At a three‑day evidentiary PCR hearing proffered experts: Shelby’s experts (pathology, radiology, biomechanics) challenged the original conclusions and posited seizure + short fall as alternatives; Dr. Riddick recanted parts of his trial opinion.
- State expert Dr. Scott Benton rebutted, concluding Bryan died of intentional blunt‑force trauma and that seizures/short falls were not supported by the record; the trial court found the new evidence would not "probably produce a different result" and denied PCR.
- The Court of Appeals affirmed, holding the trial court — as factfinder amid conflicting expert testimony — did not clearly err in denying relief.
Issues
| Issue | Plaintiff's Argument | Defendant's Argument | Held |
|---|---|---|---|
| Whether Shelby's materials qualify as "newly discovered evidence" under UPCCRA exception | Riddick's changed opinion and post‑2000 literature were not reasonably discoverable earlier and are materially new | Most information was available at trial or is merely newer commentary; not truly new | Court: Even if some evidence were "new," trial court correctly found it would not probably change outcome; affirmed denial |
| Whether a recanted expert opinion (Dr. Riddick) mandates a new trial | Riddick’s recantation and amendment of manner of death are pivotal and would likely sway a jury | Recantations are inherently suspicious; a changed opinion alone does not automatically require a new trial | Court: Recantation is not dispositive; trial court reasonably found Riddick’s new reasons unreliable; no new trial warranted |
| Whether post‑trial scientific literature undermining SBS/AHT makes a different verdict probable | Newer literature and expert testimony show SBS/AHT is scientifically contested and short falls can be fatal | Debate existed at trial; SBS/AHT not debunked and most clinicians still accept AHT; literature does not overcome physical evidence of impact | Court: Literature does not probably change outcome here (impact/bruising evidence); majority view and rebuttal testimony support conviction |
| Whether cumulative new evidence would "probably produce a different result" at a new trial | Combined expert opinions (recantation + new science + biomechanical theory) would likely lead to acquittal or different verdict | State expert rebutted each point; multiple bruises and autopsy support intentional blunt trauma; credibility issues with new testimony | Court: Trial court as factfinder resolved conflicts in State’s favor; finding that new evidence would not probably produce different result was not clearly erroneous; affirmed |
