State v. Gracie Jean Tryon, 429 P.3d 142

On Feb. 1, 2016, police stopped a truck in which Tryon was a passenger; officer smelled marijuana and arrested the driver, Ringcamp.
Officer found in the truck/purses: syringes, glass pipes with white residue, and a baggie containing a white crystalline substance.
No laboratory chemical analysis was performed on the white crystalline substance; no DNA/fingerprint testing on paraphernalia; no blood/urine test of Tryon.
Ringcamp was unavailable at trial; officer testified about Ringcamp’s statements that the substance was not Tryon’s and later “it was mine/okay.”
Tryon was convicted by a jury of possession of a controlled substance and possession of drug paraphernalia; she appealed.
Idaho Supreme Court vacated the conviction and instructed the trial court to enter a judgment of acquittal, holding the State failed to prove the substance was methamphetamine beyond a reasonable doubt.

Issue	Plaintiff's Argument	Defendant's Argument	Held
Sufficiency of evidence to show substance was a controlled substance	State: circumstantial evidence (officer experience, proximity to syringes/pipes, Ringcamp’s statements) proved substance was methamphetamine	Tryon: no laboratory analysis, officer opinion insufficient, alternative innocuous substances possible	Held: Insufficient — without chemical analysis or stronger circumstantial proof, no rational jury could find identity beyond a reasonable doubt; conviction vacated and acquittal directed
Admissibility under Confrontation Clause of Ringcamp’s out-of-custody statements (and officer’s testimony about them)	State: Ringcamp’s statements were nontestimonial so admission did not violate Confrontation Clause	Tryon: statements were testimonial and admission without cross-examination violated her confrontation rights	Held: Court declined to decide constitutional issue as unnecessary because conviction reversed on sufficiency grounds
