62 F.4th 639
1st Cir.2023Background
- Indictment charged Eric Santiago with one count of distributing or possessing with intent to distribute ≥400 grams of fentanyl under 21 U.S.C. § 841; trial resulted in conviction and a 180‑month sentence.
- Key government witness was cooperating witness Rafael Reyes, who testified Santiago visited Reyes’s house, showed a fentanyl package in Reyes’s garage, told Reyes to take it inside, and discussed a $70/gram price for ~500 grams.
- Agents recovered the package; one unidentified fingerprint was found; agents directed Reyes to text Santiago and later to make controlled payments ($5,000 then $30,000 in separate encounters). Santiago was arrested after accepting the second payment.
- At trial Reyes interpreted texts using apparent code words (e.g., “motorbike,” “scooter”) as references to fentanyl; the government also presented weight evidence showing net fentanyl weight above the 400‑gram statutory threshold.
- Santiago appealed, asserting (1) insufficient evidence, and alternatively (2) multiple trial errors: failure to give a unanimity instruction for a duplicitous count, denial of mistrial after a witness’s remark, improper lay‑opinion interpretation of coded texts (Rule 701), and Rule 16 disclosure issues about drug‑weight testimony.
Issues
| Issue | Plaintiff's Argument (United States) | Defendant's Argument (Santiago) | Held |
|---|---|---|---|
| Sufficiency of the evidence | Reyes’s testimony, corroborated by package, texts, and controlled payments, supports conviction for distribution or possession with intent to distribute | No direct proof he handled the drugs (no fingerprints, no eyewitness), texts never say "drugs," implausible he would front ~½ kg without down payment | Affirmed: credibility of Reyes + corroborating evidence sufficed under Jackson standard to support either distribution or possession‑with‑intent finding |
| Duplicitous count / unanimity instruction | The two charged theories merged given the proof (distribution shown by the same events that established possession), so no special unanimity instruction required | Failure to instruct jury to be unanimous whether conviction was for distribution or possession violated unanimity because the indictment charged both offenses in one count | Affirmed: offenses merged on the record (distribution was sole evidence of possession), so no unanimity instruction was required |
| Mistrial after Agent Rideout remark implying broader organization | The remark was isolated, elicited on cross‑examination by defense, promptly struck and the court gave strong curative instructions; overall evidence was strong | Remark prejudiced jury by implying Santiago’s connection to a larger drug organization; counsel relied on pretrial assurance that no such connection would be introduced | Affirmed: no manifest abuse of discretion denying mistrial given context, who elicited comment, curative instructions, and strength of evidence (Cresta factors) |
| Reyes’s lay‑opinion interpretation of texts (Rule 701) | Reyes, as participant, could interpret ambiguous or coded messages (e.g., "motorbike") and provide necessary context | Texts were clear; Reyes’s interpretations were unnecessary and inadmissible opinion testimony | Affirmed: testimony was permissible under Rule 701 because messages contained ambiguities/code and government established objective basis for Reyes’s understanding |
| Disclosure and admissibility of drug‑weight testimony (Rule 16 / experts) | Prior disclosure gave net weight ~499 g; cocked testimony estimating packaging weight and subsequent TFO weighing to 480 g fell within disclosed range and caused no prejudice | Astrakhan’s estimating testimony lacked adequate expert disclosure; TFO Montagano’s weighing was disclosed late, prejudicing cross‑examination | Affirmed: Rule 16 objections waived or non‑prejudicial; Astrakhan’s testimony consistent with pretrial disclosure and Montagano’s late disclosure caused no demonstrable prejudice |
