Bonanza - Season 14 Episode 14
The Witness

An elderly business associate of Bens is killed after a man, posing as Candy, tries to rob her; the woman suffers a fatal heart attack, which - since it happens during the commission of a felony - is considered to be the same as if the assailant had pulled the trigger. The real Candy, who had been assaulted at a hotel by the same man, is held in connection with the old womans death. A woman named Kate is the only one who can back up Candys alibi, but she has left town with her husband, who is the thief. Griff agrees to go after Kate and have her provide a statement. Only thing is, he discovers - as Ben and Joe do later - that she, too, has a past that, if revealed at trial, could do serious harm to Candys defense. Meanwhile, Ben is unsure about the young defense attorneys ability to defend Candy, particularly since the states attorney has a nearly spotless conviction record. But the budding lawyer is determined to play David to the prosecutors Goliath.
