954 F.3d 1184
8th Cir.2020Background
- Federal grand jury indicted Donald Loomis (and co-defendants) for conspiring to distribute ≥500 g methamphetamine, alleging the conspiracy ran from ~March 1, 2015 to Sept. 24, 2016. Loomis was convicted and sentenced to 360 months’ imprisonment.
- Law enforcement used a confidential informant to arrange controlled buys at the residence Loomis shared with codefendant Alisha Courtney; buys and a subsequent search produced multiple baggies of meth.
- Courtney confessed at the search to dealing nearly 150 pounds of meth in one year and said she obtained most of it from Loomis; multiple cooperating witnesses (Courtney, Terrance Romero, Katherine Stein) testified they bought substantial quantities from Loomis and Courtney.
- Romero testified he purchased meth from Loomis and Courtney; law enforcement also found large sums of cash on Loomis in several stops ($6,000; $4,000; $8,494).
- At trial Loomis raised multiple evidentiary objections (admission of a gun found on Romero, lay/expert testimony on meth manufacture and dealer/user distinctions, testimony about Loomis invoking his right to remain silent, and admission of meth seized at his arrest) and moved for a mistrial based on alleged prejudicial testimony; the district court denied relief.
- On appeal the Eighth Circuit reviewed unpreserved evidentiary rulings for plain error, reviewed denial of mistrial for abuse of discretion, and reviewed sufficiency of the evidence de novo; it affirmed the conviction, finding any errors harmless given overwhelming evidence.
Issues
| Issue | Plaintiff's Argument (Government) | Defendant's Argument (Loomis) | Held |
|---|---|---|---|
| Admission of gun found on Romero during traffic stop | Relevant to Romero’s credibility/connection to drug activity and conspiracy | Partnership had ended before Romero’s stop; evidence prejudicial and irrelevant | Even if admissible error, harmless given overwhelming evidence of guilt |
| Witnesses testifying as experts (Romero, DEA Agent Henry, Officer Spencer) | Testimony was admissible as lay or proper foundation existed | Witnesses lacked expert foundation/notice under rules | Any foundation error reviewed for plain error; errors not affecting substantial rights |
| Testimony about Loomis invoking right to remain silent (Henry) | Agent’s non-argumentative description was permissible (informational) | Testimony violated Griffin (comment on silence) and Fifth Amendment | Assuming error, it was harmless; no reasonable probability of different outcome |
| Admission of meth seized at Loomis’s arrest (404(b) notice) | Evidence was relevant and cumulative to the conspiracy proof | Government failed to disclose under Rule 404(b); prejudicial surprise | Any disclosure/admission error did not affect substantial rights; harmless error |
| Motion for mistrial based on Spencer’s shooting/burglary testimony and Henry’s money-laundering comment | Court promptly struck testimony and instructed jury; comments were not outcome-determinative | Testimony was highly prejudicial and merit mistrial | Denial of mistrial not an abuse of discretion; curative instruction and strong guilt evidence made error harmless |
| Sufficiency of evidence supporting conspiracy conviction | Controlled buys, search results, Courtney’s confession, multiple buyer-witnesses, and large cash support conviction | Witnesses unreliable; evidence insufficient to prove conspiracy beyond reasonable doubt | Evidence was overwhelming; conviction affirmed |
