96 F.4th 1257
9th Cir.2024Background
- Jose Jimenez-Chaidez was convicted for knowingly importing methamphetamine and cocaine into the United States from Mexico, after being apprehended with drugs hidden in his car.
- The government presented evidence of prior smuggling incidents involving Jimenez, including witness testimony and cellphone and border records, to prove his knowledge and intent.
- At trial, the government introduced location data from a witness's cellphone through FBI Agent Edasi, and testimony about the drugs' value through Agent Lewenthal.
- Jimenez objected that the court improperly admitted propensity evidence, allowed improper lay/expert testimony, failed to ensure expert testimony reliability, and denied his request for a minor-role sentencing reduction.
- The jury convicted Jimenez, and he was sentenced to 86 months; he appealed on both conviction and sentencing grounds.
- The Ninth Circuit affirmed the conviction and most evidentiary rulings, but vacated and remanded for resentencing due to errors in the sentencing reduction analysis.
Issues
| Issue | Jimenez's Argument | Government's Argument | Held |
|---|---|---|---|
| Admission of prior drug smuggling acts | Prior acts were admitted improperly as propensity evidence | Evidence relevant to knowledge/intent, not for propensity | Evidence admissible |
| Cellphone extraction testimony (lay vs. expert) | Testimony was expert, improperly admitted as lay without disclosure | Testimony only described data extraction, understandable as lay | No abuse of discretion |
| Reliability of drug-value expert | Court failed to determine reliability of expert's methods | Testimony reliable based on experience and sources used | Error was harmless |
| Minor-role sentencing reduction | Court used wrong standard in denying reduction | Applied factors listed in guidelines | Sentence vacated and remanded |
