Charles Lindbergh, the first man to cross the Atlantic by airplane, was one of the best-known celebrities of his day. In 1932 Lindbergh's 20-month-old son was kidnapped from his home. Due to Lindbergh's popularity, the crime gained considerable media attention. Dr. John F. Condon, a civilian volunteer not previously known by the Lindberghs, acted as a go-between in order to exchange the requested ransom for the baby. Condon delivered the ransom, but the baby was not where the kidnapper had promised he would be. Later, the baby was found murdered. The kidnapper, Bruno Hauptmann, was found by police after a service station attendant noticed Hauptmann using the marked ransom money. Hauptmann was convicted and eventually executed.
