Smith v. Duckworth
824 F.3d 1233
10th Cir.2016Background
- Michael Smith was convicted of two murders, confessed on videotape after a custodial interview, and was sentenced to death; convictions and sentences were affirmed on direct appeal.
- Smith later pursued state postconviction relief and federal habeas under 28 U.S.C. § 2254, asserting: intellectual disability (Atkins), improper admission of his videotaped confession (Miranda waiver), ineffective assistance of counsel in the penalty phase (mitigation investigation/presentation), and cumulative error.
- Oklahoma courts applied a statutory IQ cutoff (score ≥76 bars Atkins protection) and rejected applying the Flynn Effect; they considered SEM as implicitly built into the 76 cutoff.
- Trial court excluded neuropsychologist Dr. Bianco’s testimony on Smith’s low IQ at the Miranda suppression hearing but relied on the court’s observations of Smith’s interview to find a knowing and voluntary waiver.
- The Oklahoma Court of Criminal Appeals (OCCA) denied Smith’s Atkins, Miranda, and ineffective-assistance claims on the merits or as procedurally barred; the federal district court denied habeas relief, and the Tenth Circuit affirmed under AEDPA deference.
Issues
| Issue | Plaintiff's Argument | Defendant's Argument | Held |
|---|---|---|---|
| Intellectual disability (Atkins) — IQ cutoffs, SEM, Flynn Effect | Smith: his IQ tests (71–79), adjusted for SEM and Flynn Effect, show IQ <70 so Atkins bars execution | State/OCCA: Oklahoma statute treats IQ ≥76 as dispositive; SEM considered by statute; Flynn Effect need not be applied | Court: Affirmed OCCA; SEM effectively accounted for by statute; Flynn Effect not mandated by Supreme Court and Hooks controls — no Atkins violation shown |
| Admissibility of videotaped confession — Miranda waiver | Smith: trial court erred by excluding Dr. Bianco’s testimony on low intelligence, so waiver was not knowing/voluntary | State/OCCA: trial court observed interview, found indicia of comprehension; expert IQ testimony was not necessary or relevant | Court: Affirmed; trial court properly considered totality of circumstances based on observed interview; exclusion of testimony was not unreasonable |
| Ineffective assistance — mitigation (family/social history) | Smith: counsel failed to investigate/present extensive family abuse, head injuries, early drug/gang exposure — prejudiced sentencing | State/OCCA: new evidence was largely cumulative of trial mitigation; any new material was slight/tenuous; no reasonable probability of different result | Court: Affirmed; OCCA reasonably concluded lack of prejudice under Strickland; petitioner failed to show state factual findings unreasonable or outcome likely different |
| Ineffective assistance — mitigation (PCP, organic brain damage, low IQ) | Smith: counsel failed to develop expert evidence linking chronic PCP and brain damage/low IQ, which would have mitigated | State/OCCA: evidence was "double-edged" and could have increased perceived future dangerousness; no prejudice shown | Court: Affirmed; OCCA reasonably applied Strickland and permissibly treated evidence as potentially double-edged; Sears does not categorically preclude that view |
