889 F.3d 654
9th Cir.2018Background
- Espinoza-Valdez was observed on a mountaintop in a known Arizona marijuana-smuggling corridor with two other men; agents found a nearby campsite and he fled when agents approached.
- Upon arrest he dropped a Motorola radio; his backpack contained radio batteries/clip, food, wet wipes, toilet paper, and a carpet shoe attached; agents found no drugs.
- Expert Border Patrol testimony linked these items and the location to a drug-smuggling "scout" profile (use of Motorola radios, carpet shoes, scout encampments, seasonal smuggling).
- Months earlier Espinoza-Valdez had been apprehended in the same area and told agents he and others had been "backpacking marijuana;" that statement was admitted under Rule 404(b) with a limiting instruction.
- Government relied largely on expert drug-courier/profile evidence to infer a conspiratorial agreement to import and distribute marijuana; no drugs, no identified co-conspirators, and no confession were introduced at trial.
Issues
| Issue | Plaintiff's Argument | Defendant's Argument | Held |
|---|---|---|---|
| Sufficiency of evidence for conspiracy to import marijuana | Government: Circumstantial proof (location, items, expert profile, prior statement) shows agreement and intent | Espinoza-Valdez: Evidence insufficient to prove an agreement or intent beyond a reasonable doubt | Reversed: evidence insufficient to support conspiracy conviction |
| Sufficiency of evidence for conspiracy to distribute marijuana | Government: same circumstantial proof establishes a conspiracy to distribute | Espinoza-Valdez: no drugs, no identified co-conspirators, mere association/profile insufficient | Reversed: evidence insufficient to support conspiracy conviction |
| Admissibility/use of drug-courier profile expert testimony | Government: profile evidence properly used to explain context and typical smuggling operations | Defense: expert testimony cannot substitute for proof of agreement; is prejudicial and limited in use | Court: profile testimony is admissible only for limited purposes and cannot alone prove guilt; here it was the crux of the case and insufficient |
| Use of prior statement (404(b)) | Government: prior statement corroborative of role in smuggling | Defense: prior isolated statement and prior apprehension do not prove a conspiracy | Court: prior event admitted with limiting instruction but did not supply the missing proof of an agreement; overall evidence still insufficient |
