||Agent William Youngfellow, played by Abel Fernández
Member of the Untouchables, an elite Federal law enforcement squad. Full-blooded Cherokee from Oklahoma. All-American football player at Carlisle University. Responsible for the break-up of the Oklahoma City booze ring. Youngfellow was the squad's ace undercover man. During the course of the show he went undercover on such diverse assignments as a waiter, a taxi driver, a laborer, a soda jerk, a stevedore, and a flagpole sitting clown. Unlike the remainder of the Untouchables squad, Youngfellow rarely smoked. He's only seen with a cigarette in his mouth on a couple of occasions while the others smoked like chimneys.
