United States v. Terry Schwarck
719 F.3d 921
8th Cir.2013Background
- Schwarck was convicted by a jury of conspiracy to distribute and possess with intent to distribute 500 grams or more of methamphetamine.
- The district court sentenced Schwarck to 240 months’ imprisonment.
- Undercover officer Ripley investigated Schwarck and testified about two meth transactions involving Christine Snyder.
- Schwarck argued he was a user, not a dealer; the government admitted Koepke as an expert on meth distribution methods.
- Koepke described dealer practices (security cameras, RF detectors, using a trusted helper, currency patterns) to link to Schwarck’s activities.
- Schwarck timely appealed, challenging Koepke’s testimony as improper under Rule 702/Daubert and its prejudicial impact.
Issues
| Issue | Plaintiff's Argument | Defendant's Argument | Held |
|---|---|---|---|
| Whether Koepke’s expert testimony was properly admitted | Schwarck contends it was irrelevant and prejudicial. | Government argues it explained meth distribution MO and aided the defense. | Admission was not an abuse of discretion; it aided understanding of trafficking. |
| Whether Koepke’s testimony was cumulative | Koepke’s testimony duplicated other witnesses’ evidence. | Testimony added unique explanatory value about drug trade. | Not unduly cumulative; not unfairly prejudicial given probative value. |
| Whether Koepke’s testimony impermissibly invoked a drug courier profile | Koepke’s testimony resembles prohibited courier-profile evidence. | Testimony rebutted defendant’s defense and elucidated drug trade practices. | Permissible as relevant to the defense and not an impermissible profile. |
