Segura v. United States
United States Supreme Court
468 U.S. 796 (1984)
Based on informant tips and independent surveillance, drug agents entered the couple's (defendants) apartment without a warrant, arrested them, and remained inside for 19 hours to prevent evidence destruction while observing (but not searching for) incriminating items, before finally obtaining a warrant and conducting a full search that turned up additional evidence; the district court suppressed all the seized evidence as tainted by the illegal entry, and the court of appeals affirmed suppression only as to evidence observed before the warrant, allowing the warrant-based search evidence to stand.
Whether criminal evidence will be suppressed under the exclusionary rule when law enforcement had an independent source of information justifying a valid search and seizure of that evidence.
