355 P.3d 355
Wash. Ct. App.2015Background
- Michael James Morris was convicted of first-degree assault for injuring his six-week-old daughter, A.M., who was admitted with severe retinal hemorrhages, brain bleeding, and signs of traumatic injury after Morris cared for her on May 29, 2009.
- Medical testimony: State expert Dr. Kenneth Feldman diagnosed abusive head trauma (AHT) based on differential diagnosis (acceleration/deceleration/whiplash forces); pediatric ophthalmologist Dr. Erin Herlihy corroborated severe retinal hemorrhages inconsistent with minor accidental trauma.
- Defense theory: alternative causes (viral meningitis, hypoxia, clotting problems, accidental injury) offered by defense experts; Morris gave statements and a text admitting he shook the baby.
- Morris filed a personal restraint petition claiming ineffective assistance of counsel for failing to effectively challenge Dr. Feldman’s causation testimony (arguing Frye and ER 702 issues and biomechanical criticisms) and asserting a due process violation based on allegedly false/misleading evidence.
- The court reviewed admissibility under Frye and ER 702, evaluated counsel’s strategic choices under Strickland, and considered whether any deficient performance caused actual prejudice to the outcome.
Issues
| Issue | Plaintiff's Argument | Defendant's Argument | Held |
|---|---|---|---|
| Admissibility of AHT/shaking causation under Frye | Dr. Feldman’s causation testimony (AHT/shaking) lacks general acceptance; expert should be excluded | AHT and shaking as causes are generally accepted; State produced professional position statements and literature supporting AHT | Court: testimony satisfied Frye; AHT/shaking is generally accepted and admissible |
| Admissibility/weight under ER 702 (reliability/helpfulness) | Feldman’s differential etiology is unreliable; biomechanical literature undermines shaking causation | Feldman qualified as an expert; used differential diagnosis method and acknowledged limits; cross-examined on contrary literature | Court: ER 702 satisfied — expert qualified; testimony helpful and not misleading; challenges go to weight, not admissibility |
| Ineffective assistance for failing to press Frye/ER 702 and for cross-examination | Trial counsel failed to expose flaws, lacked knowledge of biomechanical literature, and missed key challenges | Strategic decisions to cross-examine rather than pursue exclusion were reasonable; counsel probed evidence base and lucid-interval literature on cross | Court: No deficient performance shown; counsel’s choices were strategic and record shows adequate cross-examination |
| Prejudice (but-for effect on verdict) | Excluding or discrediting Feldman would have changed outcome | Independent strong evidence (ophthalmologist, admissions, timing, child acting normal before care) would sustain verdict | Court: No prejudice — even without Feldman jury could find Morris guilty beyond reasonable doubt |
| Due process claim for presentation of false/misleading evidence | State presented evidence it knew/should have known was false or misleading | The record shows difference of scientific opinion, not known falsity; no Brady or perjured-witness situation | Court: Denied — no due process violation proven |
