880 F.3d 506
9th Cir.2018Background
- Urias Espinoza, a Mexican national who ran a clothing business, was stopped at the Otay Mesa Port of Entry and a vehicle search uncovered ~12 kg of methamphetamine hidden in hollowed rear seats.
- She was charged with importation of methamphetamine under 21 U.S.C. §§ 952, 960; at trial she denied knowledge and claimed her next-door neighbor in Mexico packed the car as a "blind mule" scheme.
- The defense attempted to introduce evidence tying the neighbor to drug activity: a Facebook screenshot/photographs, and documentary proof of the neighbor’s prior convictions (importation of methamphetamine; possession with intent to distribute marijuana) and prior deportation.
- The district court excluded that evidence as too speculative, applying a standard that required "substantial evidence" directly connecting the third party to the crime (relying on Perry and Ignacio), and the jury convicted Urias Espinoza.
- The Ninth Circuit held the district court applied the wrong legal standard: under Ninth Circuit precedent (Armstrong) relevant third-party culpability evidence should be admitted unless barred by another evidentiary rule; the excluded evidence was relevant and some items improperly excluded under Rule 404(b).
- Because the erroneous exclusion was not harmless (the sole contested element was knowledge and the government’s proof was largely circumstantial), the court reversed and remanded for a new trial.
Issues
| Issue | Plaintiff's Argument | Defendant's Argument | Held |
|---|---|---|---|
| Admissibility of third-party culpability evidence | Urias sought to admit evidence suggesting neighbor had motive, opportunity, and knowledge to pack the car | Government contended evidence was speculative and not directly connecting neighbor to the crime | Court: District court abused discretion by applying a "substantial evidence" threshold; under Armstrong, minimally relevant third-party culpability evidence is admissible unless excluded by another rule |
| Application of Federal Rule 404(b) to neighbor’s convictions | Convictions are probative of knowledge, ability, and connections (non-propensity purpose) | Govt argued convictions were remote and improperly propensity evidence | Held admissible for non-propensity purposes; exclusion under 404(b) was erroneous because evidence tended to prove knowledge and opportunity |
| Relevance of deportation, photos, Facebook screenshot | Deportation shows why neighbor couldn’t drive across border; photos/Facebook identify neighbor and link to convictions | Govt argued such materials were speculative or prejudicial | Court: These items were relevant to the blind-mule theory and should not have been excluded on speculation grounds |
| Harmlessness of evidentiary error | Error was prejudicial because knowledge was the central contested element and excluded evidence could supply an identifiable alternative actor | Govt argued error was harmless given drugs were found and circumstantial indicia of knowledge | Court: Error not harmless; government failed to show it was more probable than not the verdict was unaffected; reverse and remand for retrial |
