Case of the Missing Man (1935)

After an argument with his newspaper's city editor, press-photographer Jimmy Hudson quits his job and takes up free-lancing as a street-photographer for a living. He stumbles across the robbing of a jewelry store and takes a picture of one of the robbers as he is leaving the scene-of-the-crime in which murder has also been committed. At the risk of his own life, over the protests of his sweetheart, he sets a trap to catch the crook.
