Case Facts & Court Holding

Key Facts & Case Background

During Prohibition, federal agents arranged to buy illicit whiskey from defendants George Carroll and John Kiro, but the deal never materialized. Months later, the same agents recognized the defendants driving the same Oldsmobile roadster on a highway known for transporting illegal liquor from Detroit to Grand Rapids. Based on their prior interaction and knowledge of the defendants’ reputation as bootleggers, the agents pursued and stopped the vehicle. Without a warrant, they searched the car and discovered 68 quarts of whiskey concealed behind the seat upholstery. The defendants were arrested and charged with transporting intoxicating liquor in violation of the National Prohibition Act. At trial, the defendants moved to suppress the whiskey as evidence, arguing it was obtained through an unconstitutional search and seizure. The trial court denied the motion, and the defendants were convicted.
