United States v. Archuleta
737 F.3d 1287
10th Cir.2013Background
- Archuleta, leader of Tortilla Flats, a Sureño affiliate in Farmington, NM, was charged in a multi-count drug-conspiracy and firearms case.
- In June–July 2009, Archuleta allegedly orchestrated methamphetamine smuggling from Mexico using two female mules (Roberts and Candi Ramirez) and a male associate (Adam Ramirez).
- Plan involved crossing drugs at the border; trafficking disrupted by border patrol arrest of the parties; coconspirators later implicated Archuleta.
- Indictment charged Counts 1, 2, 4, 5, and 7 (conspiracy, possession with intent to distribute, felon in possession, and related firearm counts).
- Before trial, Archuleta moved to exclude gang-expert testimony; district court held two hearings allowing expert Lujan to testify.
- Jury convicted Archuleta on Counts 1, 2, 5, 7; acquitted on Counts 4 and 6; sentences issued concurrently.
Issues
| Issue | Plaintiff's Argument | Defendant's Argument | Held |
|---|---|---|---|
| Whether Lujan’s testimony violated Rule 403 | Archuleta argues testimony was unfairly prejudicial and cumulative. | Archuleta contends prejudicial impact outweighed probative value. | District court did not abuse discretion; harmless error. |
| Whether Lujan’s testimony complied with Rule 702 | Testimony aided by specialized gang-knowledge and context for jurors. | Evidence not necessary; alternative testimony by Ramirez sufficient. | No plain error; testimony assisted understanding of conspiracy. |
| Whether Lujan’s testimony violated Rule 704(b) | Testimony suggested Archuleta’s mental state equating to guilt. | Testimony expressed facts from which mental state could be inferred, not direct opinion. | No plain error; substantial evidence of knowledge from coconspirators supported conviction. |
| Whether admission of Lujan’s testimony affected substantial rights (plain-error standard) | Unfair prejudicial impact could have altered verdict on July 2009 conspiracy. | Independent evidence overwhelmed any error; harmless. | Harmless error; conviction affirmed. |
