United States v. Noe Machado-Erazo
901 F.3d 326
D.C. Cir.2018Background
- Defendants (Ayala, Machado-Erazo, Martinez-Amaya) were MS‑13 members/leadership in the D.C. area and were charged in a RICO conspiracy and related murders and firearm counts; after a three‑week trial the jury convicted all three.
- Government proof included co‑conspirator testimony, wiretaps, recorded clique meetings, and over 200 exhibits; some violent acts involving Normandie and Sailors cliques were introduced at trial.
- Machado‑Erazo and Martinez‑Amaya received life sentences for RICO conspiracy and VICAR murder plus a consecutive §924(c) term; Ayala received long concurrent terms for RICO and murder counts.
- On appeal defendants challenged (1) admission of numerous violent acts as other‑crimes evidence under Fed. R. Evid. 404(b) and Rule 403 balancing, and (2) admission of detailed cell‑site expert testimony by FBI SA David Magnuson (including specific distance/range opinions) under Fed. R. Evid. 702 and Fed. R. Crim. P. 16.
- The D.C. Circuit affirmed: it held the violent‑acts evidence admissible (mostly intrinsic to the conspiracy or charged as overt acts) and found the district court abused its discretion admitting Magnuson’s specific‑location opinions without adequate Rule 16 disclosure or Daubert/Rule 702 vetting, but deemed that error harmless given the strength and breadth of other evidence.
Issues
| Issue | Plaintiff's Argument | Defendant's Argument | Held |
|---|---|---|---|
| Admissibility of violent acts (Rule 404(b)/403) | Gov: acts show conspiracy background, organizational structure, intent, and some were charged overt acts — admissible and probative | Defs: testimony/photo evidence of multiple violent acts was irrelevant to them, prejudicial, and amounted to guilt by association | Court: abuse‑of‑discretion review; evidence was largely intrinsic or overt acts, temporally connected and probative of conspiracy/structure; Rule 403 concerns dispelled by cumulative proof — admission affirmed |
| Cell‑site expert testimony (Rule 702 / Rule 16) | Gov: Magnuson qualified; would testify to general cell‑tower coverage areas (not exact location); methodology reliable per Daubert | Defs: Gov failed to disclose Rule 16 summary of specific opinions; Magnuson exceeded proffer, gave precise distance/range opinions beyond his disclosed report and expertise | Court: district court abused discretion by admitting specific distance/range opinions without proper Rule 16 disclosure or Daubert/702 foundation; error occurred but was harmless given abundant corroborating evidence |
| Standard of review & prejudice (harmless‑error) | Gov: any error harmless because other independent proof tied defendants to murders | Defs: erroneous expert testimony substantial and tainted verdict on VICAR/§924(c) counts | Held: although admission of specific‑location testimony was erroneous, it did not affect defendants' substantial rights given undisputed co‑conspirator testimony, wiretaps, recordings, and other evidence; convictions stand |
