Segura v. United States, 468 U.S. 796 (1984)

Facts

  • Federal and state agents suspected Andrés Segura and Luz Marina Colón of distributing cocaine from their apartment based on informant information and surveillance.
  • Agents observed Colón deliver a bulky package to Parra in a parking lot while Segura and another individual were in a nearby restaurant.
  • Agents later stopped Parra and the other individual, found cocaine, and arrested them.
  • After receiving Miranda warnings, the other arrestee stated he purchased the cocaine from Segura and that Colón delivered it.
  • An Assistant U.S. Attorney authorized arrests and advised that a search warrant likely could not be obtained until the next day, instructing agents to secure the premises to prevent destruction of evidence.
  • Agents arrested Segura in the building lobby, took him upstairs, and entered the apartment when Colón opened the door, without consent and without a warrant.
  • Agents conducted a limited security check and observed drug paraphernalia in plain view; Colón was arrested.
  • Agents remained in the apartment to secure it while awaiting a warrant; due to administrative delay, the warrant issued about 19 hours after entry.
  • Executing the warrant, agents seized cocaine and narcotics records, along with items earlier observed during the initial entry.

Issues

  1. Whether the exclusionary rule requires suppression of evidence first seized under a valid search warrant when officers previously made an unlawful, warrantless entry into the premises.
  2. Whether the 19-hour securing of the apartment while awaiting a warrant was an unreasonable seizure requiring suppression of evidence later found under the warrant.

Decision

  • The Court affirmed the admissibility of evidence first discovered and seized during the search conducted under the valid warrant.
  • The Court reasoned that the warrant was based on information obtained before, and independent of, the illegal entry; the later-seized evidence was not the product of the illegality.
  • The Court held that the 19-hour securing of the apartment did not require suppression of evidence discovered under the warrant.
  • Items observed in plain view during the initial unlawful entry were suppressible, but that illegality did not taint evidence later obtained for the first time under the warrant.
  • The exclusionary rule bars not only evidence directly obtained through a Fourth Amendment violation but also derivative evidence, unless the challenged evidence was acquired from a genuinely independent source.
  • Under the independent source doctrine, evidence seized pursuant to a valid warrant is admissible when the warrant and supporting probable-cause showing are wholly independent of prior unlawful police conduct.
  • A temporary seizure of premises to preserve the status quo while officers diligently seek a warrant, supported by probable cause, does not automatically require suppression of evidence later seized under the warrant.

Conclusion

The Court held that a prior illegal entry into a residence does not compel suppression of evidence first seized under a later, valid warrant when the warrant is supported by information independent of the entry, and that securing the premises while awaiting the warrant did not itself justify excluding the warrant-based evidence.
