The petitioner was arrested in Chicago, Illinois, on the morning of January 16, 1964, for possession of narcotics.
The Chicago police officers who made the arrest found a package containing heroin on his person and he was indicted for its unlawful possession. Prior to trial he filed a motion to suppress the heroin as evidence against him, claiming that the police had acquired it in an unlawful search and seizure in violation of the Fourth and Fourteenth Amendments.
At the hearing on the motion to suppress, the petitioner testified that up until a half hour before he was arrested he had been at "a friend's house" about a block away, that after leaving the friend's house he had "walked with a lady from 48th to 48th and South Park," and that, as he approached 49th Street and Calumet Avenue, "[t]he Officers stopped me going through the alley."
"The officers," he said, "did not show me a search warrant for my person or an arrest warrant for my arrest."
The petitioner did not identify the "friend" or the "lady," and neither of them appeared as a witness. The arresting officers, Jackson and Arnold, then testified about receiving information from a confidential informant that morning. The informant, whom the officers had known for one to two years and who had provided reliable information leading to multiple arrests and convictions, stated that the petitioner was selling narcotics and had them on his person near 47th and Calumet.
The officers drove to the area, the informant pointed out the petitioner, and after observing him separate from a woman, meet briefly with a man, and then hurry between two buildings upon seeing the police car, the officers approached, informed him of the information, placed him in the vehicle, and searched him, finding the heroin in a cigarette package. When defense counsel asked for the informant's name and address on cross-examination, the prosecution objected and the court sustained the objections.
The trial court denied the motion to suppress. The petitioner was convicted based on the heroin evidence. The Illinois Supreme Court affirmed the conviction. The U.S. Supreme Court granted certiorari to review the claim regarding the suppression hearing.
