371 P.3d 1056
N.M. Ct. App.2016Background
- In 2003, nine-year-old P.W. reported sexual contact by Mario Carmona; a Sexual Assault Nurse Examiner (SANE) Lydia Vandiver performed an exam, collected labeled swabs and a standardized SANE kit, and turned the kit over to SANE program custody.
- Defendant was indicted for criminal sexual contact of a minor; after serving time elsewhere, he provided a buccal swab in 2011 for DNA comparison.
- Before trial, SANE Vandiver died (2013). The State’s DNA expert, Alanna Williams, compared DNA from the SANE swabs to Defendant’s buccal swab and concluded there was a match.
- Defense moved to suppress: arguing the State could not establish a reliable chain of custody or the relevance of Williams’s opinion without Vandiver’s testimony, and that admitting the evidence would violate the Sixth Amendment Confrontation Clause.
- The district court suppressed the DNA evidence on three grounds: not relevant, unreliable chain of custody, and Confrontation Clause violation. The State appealed.
Issues
| Issue | Plaintiff's Argument | Defendant's Argument | Held |
|---|---|---|---|
| Admissibility/relevance of expert DNA opinion based on labeled swabs | Williams relied on physical swabs and laboratory testing; her opinion is relevant to prove defendant’s DNA was on victim | Williams’s opinion is only relevant if the swabs are shown to have come from P.W.; without Vandiver, origin is unproven | Excluded — expert’s opinion derived relevance from Vandiver’s labels; without her statements linking swabs to P.W., testimony would concern unknown swabs and be irrelevant |
| Chain of custody sufficiency to identify swabs as from P.W. | State offered chain-of-custody witnesses and SANE program custodian (Monahan) who handled/transported evidence | Defense challenged gaps and argued provenance depended on Vandiver’s contemporaneous markings and testimony | Court found State failed to establish a reliable chain of custody sufficient to substitute for Vandiver’s testimony |
| Confrontation Clause: may expert testify about testing when original examiner is unavailable? | State: expert may rely on underlying records/labels; Williams’s testimony is non-testimonial or admissible under rules allowing experts to rely on others’ data | Defense: labels and inventory are testimonial statements made to establish evidence for prosecution; admitting expert opinion based on them denies cross-examination | Held — admission would violate the Sixth Amendment; Vandiver’s statements on the kit were testimonial (primary purpose to aid prosecution) and her unavailability bars use of Williams’s opinion that depends on those statements |
| Application of ‘primary purpose’ test to SANE evidence collection | State: SANE collection was for medical/forensic purposes not primarily to accuse a known suspect; Williams’s reliance is routine and non-testimonial | Defense: P.W. had already identified Carmona before the exam; SANE kit/labels were prepared with prosecution in mind and expected future use in investigation | Court: primary purpose was prosecutorial (victim had identified defendant; SANE kits standardized to create evidence for prosecution); statements were testimonial and barred without live testimony |
Key Cases Cited
- Crawford v. Washington, 541 U.S. 36 (recognizes Confrontation Clause bars admission of testimonial hearsay unless declarant testifies)
- Davis v. Washington, 547 U.S. 813 (articulates the primary-purpose test for whether statements are testimonial)
- Melendez-Diaz v. Massachusetts, 557 U.S. 305 (laboratory certificates created for prosecution are testimonial)
- Bullcoming v. New Mexico, 564 U.S. 647 (reports created for evidentiary use are testimonial; expert may not substitute testimony for non-testifying analyst)
- Williams v. Illinois, 567 U.S. 50 (plurality/concurring splintered opinions on expert reliance on others’ lab work; no single controlling rationale)
- State v. Navarette, 294 P.3d 435 (N.M. 2013) (interprets Williams for New Mexico: out-of-court statements disclosed as basis for an expert’s opinion are offered for truth and subject to Confrontation Clause analysis)
