Mincey v. Arizona

Undercover officer Barry Headricks arranged to buy heroin from Mincey (plaintiff), and when officers later went to Mincey's home, Headricks was shot and killed; other officers then searched Mincey's home thoroughly over four days without ever obtaining a warrant. Mincey's pretrial motion to suppress the evidence from that warrantless search was denied, and he was convicted of murder, assault, and drug charges; the Arizona Supreme Court upheld its prior rule creating a homicide-scene exception to the warrant requirement, and the U.S. Supreme Court granted certiorari.
