The Star Witness is a 1931 American pre-Code crime drama film produced and distributed by Warner Bros. and directed by William A. Wellman.

Campo enters the house, assaults Grandpa for confronting him, threatens the family with harm if they talk, and flees by the back exit.

Whitlock's assistant plans to put the witnesses in protective custody in jail once Campo is indicted, but the gang acts faster.

Pa Leeds is kidnapped and, after he rejects a bribe for the family to recant their identification of Campo, is badly beaten and dumped beside a road.

Killing time in the apartment where he is being held, Donny starts showing one of his captors a baseball pitch, when he hears Grandpa's fife outside.
