Dragnet 76 – The Big Hit and Run Killer - 1954

A truck kills an old lady and her little grandson at a crossing and drives away. The owner of the truck asserts that he let a man called Paul lend the truck for one hour, but he doesn’t know the last name of this man or where he lives. The police must investigate all circumstances, but should Friday and Smith really spend lots of resources on trying to find a man they hardly believe exists at all?
