United States v. Soto-Peguero, 978 F.3d 13

Background

DEA task force wiretapped Mejia-Ramos (Jan–July 2015) and intercepted calls showing Soto-Peguero supplied heroin and that his girlfriend Mercedes Cabral would deliver a package July 6, 2015.
Cabral was stopped minutes after leaving their apartment and arrested with close to one kilogram of heroin in her purse.
Task Force members surrounded Soto-Peguero's apartment that night; someone inside fired a shot through the front door; officers then entered without a warrant and found heroin and a firearm.
The next day agents obtained a search warrant whose affidavit described evidence allegedly seen during a prior “security sweep”; agents executed the warrant and found more contraband.
Soto-Peguero moved to suppress the evidence from the warrantless entry and the subsequent warranted search; the district court denied suppression under the inevitable discovery doctrine and the court below found probable cause existed independent of the allegedly illegal observations.
After conviction on drug and § 924(c) firearm charges, Soto-Peguero challenged (1) the denial of suppression and (2) a two-level U.S.S.G. § 3B1.1(c) role enhancement; the First Circuit affirmed.

Issues

Issue	Plaintiff's Argument	Defendant's Argument	Held
1) Warrantless entry/protective sweep — exigent circumstances and plain view	Entry was justified because Cabral’s unexplained absence and inability to contact her could create exigency; officers were fired upon, supporting a protective sweep and plain-view observations	No exigency justified forced entry; protective sweep exceeded scope; alleged plain-view observations were inaccurate	Exigent circumstances justified initial entry; court found some sweep actions exceeded scope but nonetheless admitted evidence under inevitable discovery
2) Inevitable discovery — admissibility of evidence found after warrant	Agents would have sought and obtained a warrant regardless; thus evidence inevitably would have been discovered lawfully	Warrant was tainted by illegally obtained evidence; admitting it would encourage police misconduct and sully Fourth Amendment protections	Inevitable discovery applies: government proved by preponderance that a warrant would have been sought/issued and the evidence would have been found lawfully
3) Officer misconduct / Madrid exception — should misconduct preclude inevitable discovery	No flagrant or exploitative misconduct; no bad‑faith misdescription or deliberate exploitation of presence	Officers ‘‘tore the residence apart,’’ opened vents/drawers, and gave inconsistent testimony—conduct like Madrid warrants suppression despite inevitability	Madrid exception inapplicable: conduct here was not so egregious or proven to be done in bad faith; district court’s credibility findings control
4) Sentencing — U.S.S.G. § 3B1.1(c) two‑level role enhancement	Soto‑Peguero supervised and directed Cabral (multiple communications, others treated Cabral as courier), satisfying preponderance	He and Cabral were equal participants; only limited evidence he told her to "send"	District court did not clearly err: enhancement affirmed (defendant supervised at least one other participant)
