About 8 a.m. on March 17, 1962, an armed robber entered the business premises of the Diamond Cab Company in Baltimore, Maryland. He took some $363 and ran. Two cab drivers in the vicinity, attracted by shouts of ‘Holdup,’ followed the man to 2111 Cocoa Lane. One driver notified the company dispatcher by radio that the man was black and about 5 8 tall, wearing a light cap and dark jacket, and that he had entered the house on Cocoa Lane. 

The dispatcher relayed the information to police who were proceeding to the scene of the robbery. Within minutes, police arrived at the house in a number of patrol cars. An officer knocked and announced their presence. Mrs. Hayden answered, and the officers told her they believed that a robber had entered the house, and asked to search the house. She offered no objection.

The officers spread out through the first and second floors and the cellar in search of the robber. Hayden was found in an upstairs bedroom feigning sleep. He was arrested when the officers on the first floor and in the cellar reported that no other man was in the house. Meanwhile an officer was attracted to an adjoining bathroom by the noise of running water, and discovered a shotgun and a pistol in a flush tank; another officer who, according to the District Court, was searching the cellar for a man or the money found in a washing machine a jacket and trousers of the type the fleeing man was said to have worn. A clip of ammunition for the pistol and a cap were found under the mattress of Hayden’s bed, and ammunition for the shotgun was found in a bureau drawer in Hayden’s room. All these items of evidence were introduced against Hayden at his trial.

Hayden was convicted. And the appeal of his case made it to the US Supreme Court.
