Just one published criminal case from the Tenth Circuit last week:
Sufficiency of evidence of drug dealing
In United States v. Duran, the Tenth Circuit held that the evidence was sufficient to support Mr. Duran's drug-distribution, conspiracy, and telephone-count convictions. The opinion contains an interesting discussion of what evidence will suffice absent controlled purchases or the actual observation of drugs. Here, the evidence consisted primarily of recorded telephone calls, as interpreted by law-enforcement witnesses.
The Duran Court rejected Mr. Duran's relevance, prejudice, hearsay, and foundational challenges to law-enforcement testimony about his involvement in previous controlled buys.
The Court further rejected Mr. Duran's opinion, hearsay, and prejudice challenges to an officer's lay interpretation of code words on the recorded telephone calls, reminding us that "[l]aw-enforcement agents can ordinarily testify that the defendants were engaged in drug trafficking because this testimony constitutes opinion evidence on a fact issue." And the Court held that an agent's expert interpretation of the code words was also properly admitted.
