Friday (Jack Webb) and Jacobs (Barney Phillips) put in a lot of long, hard hours to locate the hit-and-run driver who struck down pedestrian Sheila Gordon (Joyce McCluskey). The extra effort seems to have paid off when a man named Ralph Angelo is brought to trial. All that is needed to secure a conviction is the testimony of the fully-recovered Sheila Gordon--but the woman seems to have vanished from the face of the earth! This episode is based on a Dragnet radio program, originally broadcast April 20, 1950. ~ Hal Erickson, Rovi
