Good Day for a Hanging(1959)

When the local sheriff is killed after a bank robbery, ex-lawman Ben Cutler collars the apparent killer, Eddie Campbell. Because of his background as a local youth who spent time living with the Cutlers, Eddie gets the benefit of the doubt from Ben's daughter and his wife-to-be. Ben is firm in his belief that Eddie is guilty, and as the matter is debated in a divisive court battle, it will soon become clear whether he's right.
