Read the full case

Background

  • Patrick McGaffee, committed under Washington's SVPA in 1998 for offenses against boys, sought an unconditional release trial in 2013; a jury found he remains a sexually violent predator and the trial court ordered continued confinement.
  • State's expert (Dr. Goldberg) diagnosed pedophilic and fetishistic disorders and used structured clinical judgment combining actuarial tools (Static-99R, Static 2002R, VRAG-R) and dynamic measures (SRA-FV, STABLE 2007) to conclude McGaffee is more likely than not to reoffend.
  • Defense expert (Dr. Abbott) testified McGaffee did not have a qualifying mental abnormality and criticized the State's instruments (including VRAG-R and SRA-FV) but did not present his own risk-assessment scores.
  • Pretrial Frye hearing admitted testimony based on the SRA-FV; lower court found SRA-FV generally accepted and reliably applied in the field.
  • Trial disputes included admissibility of SRA-FV under Frye, probative value and prejudice of percentile rankings (94th percentile on Static-99R), limits on cross-examining/criticizing actuarial tools, refusal to ask a jury-submitted question about Dr. Abbott’s instruments, and alleged prosecutorial misconduct in closing argument.

Issues

Issue McGaffee's Argument State's Argument Held
Admissibility of SRA-FV under Frye SRA-FV is novel, lacks general acceptance and reliable application SRA-FV is generally accepted and can be reliably applied; comparable use in other cases Court affirmed admissibility under Frye (follows Pettis and Ritter)
Use of percentile ranking (94th percentile) Ranking is irrelevant/misleading and unfairly prejudicial (may be conflated with absolute risk) Percentile is relevant comparative information and expert clarified it is not absolute risk Admission not an abuse of discretion; probative and jury sought clarification
Limiting defense expert's criticism of VRAG-R Court improperly limited Abbott from fully criticizing VRAG-R, violating right to present a defense Court properly excluded speculative opinions (e.g., predicting future cross-validation results) No constitutional violation; exclusion of speculative testimony upheld
Refusal to ask jury's question re: instruments Dr. Abbott used Excluding question prevented jury from learning what instruments Dr. Abbott relied on and impaired defense Question was outside scope of Abbott's testimony and would have required exploring matters defense chose not to elicit Court did not abuse discretion in declining to ask the question
Prosecutorial misconduct in closing Several closing remarks improperly shifted burden, minimized standards, and capitalized on excluded/absent defense evidence Remarks were fair inferences from the evidence, clarified limits of actuarials, and did not shift burden No prosecutorial misconduct; comments viewed in context were permissible

Key Cases Cited

  • Frye v. United States, 293 F. 1013 (D.C. Cir. 1923) (establishes general-acceptance test for novel scientific evidence)
  • In re Det. of Post, 170 Wn.2d 302 (Wash. 2010) (burden on State and SVPA legal standards for continued commitment)
  • Pettis v. In re Det. of Pettis, 188 Wn. App. 198 (Wash. Ct. App. 2015) (admissibility and general acceptance of SRA-FV upheld)
  • In re Det. of Ritter, 192 Wn. App. 493 (Wash. Ct. App. 2016) (SRA-FV use admissible when combined with Static-99R)
  • In re Meirhofer, 182 Wn.2d 632 (Wash. 2015) (experts not limited to actuarial tests; State need not show any single tool exceeds 50%)
  • In re Det. of Brooks, 145 Wn.2d 275 (Wash. 2001) ("more likely than not" means probability >50% for reoffense)
