United States v. Diaz-Concepcion
860 F.3d 32
1st Cir.2017Background
- On Oct. 19, 2014, police stopped Díaz-Concepción for a helmet violation and found a loaded machine gun, two loaded magazines, 13 individually packaged bags of cocaine, one bag of marijuana, and $3,138.
- He was indicted on drug distribution (21 U.S.C. § 841(a)(1)) and a § 924(c) count alleging possession of a machine gun in furtherance of drug trafficking.
- Through plea negotiations the indictment was dismissed and Díaz‑Concepción waived indictment to plead guilty to a one-count information charging possession of a firearm in furtherance of a drug trafficking crime under 18 U.S.C. § 924(c)(1)(A)(i) (omitting the machine‑gun enhancement).
- He signed a plea agreement and stipulation of facts admitting he possessed a firearm in furtherance of a drug trafficking crime and acknowledging the government could prove the facts at trial; he affirmed this at a magistrate plea colloquy.
- The district court accepted the plea, sentenced him to 8 years (between the parties’ agreed recommendations of 7 and 10 years), and noted he could still appeal a claim that the plea was involuntary.
Issues
| Issue | Plaintiff's Argument (Gov't) | Defendant's Argument (Díaz‑Concepción) | Held |
|---|---|---|---|
| Whether the plea was knowing and voluntary under Fed. R. Crim. P. 11(b)(1)(G) | Court satisfied Rule 11 by reading the charge, confirming competence, and having the prosecutor summarize the facts the government could prove. | Plea was involuntary because the magistrate judge failed to explain the elements of § 924(c), specifically that a predicate drug‑trafficking crime (intent to distribute) was required. | No error: colloquy, plea agreement, stipulation of facts, and indictment history put defendant on notice; Rule 11 satisfied. |
| Whether any Rule 11 error (if present) was plain and prejudicial | Even if error, government’s evidence was overwhelming and defendant benefited greatly from the plea, so no reasonable probability he would have gone to trial. | Any omission was plain error that affected substantial rights because evidence of intent to distribute and nexus to the firearm was weak. | No plain error: strong evidence of intent to distribute and nexus; defendant unlikely to have rejected plea given onerous alternative. |
| Whether plea lacked factual basis in violation of Fed. R. Crim. P. 11(b)(3) | Stipulation and government proffer supplied a sufficient factual basis; defendant admitted facts. | Contends facts insufficient (perfunctorily raised). | Factual basis adequate; plea supported by rational basis in admitted facts. |
| Whether appellate waiver bars this appeal | Waiver does not bar challenge to the voluntariness/validity of the plea. | N/A (defendant invoked right to challenge plea validity). | Allowed appellate review on validity of plea despite waiver. |
