930 F.3d 963
8th Cir.2019Background
- March 2017 traffic stop of a rental truck led to the discovery of five one-kilogram bundles of cocaine; Gutierrez-Ramirez was a passenger and arrested.
- Driver Duarte testified he was hired to drive the truck and claimed limited knowledge of the cargo; Gutierrez-Ramirez admitted post‑Miranda that she knew there was "coke" and agreed to transport it for money.
- Government sought to admit a 2014 Arizona traffic stop of Gutierrez-Ramirez under Fed. R. Evid. 404(b): a trooper found $60,000 hidden in a pillowcase and she said she transported it because she needed money.
- The district court preliminarily admitted the 2014 incident limited to intent/knowledge and gave a limiting jury instruction.
- DEA Special Agent Mark Hooten testified as an expert that drug traffickers typically would not entrust a valuable shipment to an uninformed courier (to rebut the "unknown courier" defense); the district court admitted the testimony under Rule 702.
- Gutierrez-Ramirez moved for a new trial arguing (1) the 404(b) prior-act evidence was inadmissible and (2) Hooten's testimony failed Daubert; the district court denied relief. The Eighth Circuit affirmed.
Issues
| Issue | Plaintiff's Argument | Defendant's Argument | Held |
|---|---|---|---|
| Admissibility of 404(b) prior-act evidence | 2014 stop was unfair propensity evidence and inadmissible | Prior act shows intent/knowledge, was similar, timely, and supported | Admission not an abuse of discretion; admissible for intent/knowledge with limiting instruction |
| Admissibility of expert testimony (Daubert) | Hooten's testimony about dealer practices was unreliable and should be excluded | Hooten's extensive field experience qualifies under Rule 702; such law-enforcement expertise is routinely admissible | No plain error; testimony admissible based on experience and controlling precedent |
