Despite the CBS sales team’s best efforts, national sponsorship for Luke Slaughter was non-existent. Only the May 4th episode managed to get sponsorship from O'brien Paints. All the components for an excellent series were there, except the timing. By Memorial Day, the writing was on the wall.

This is audio from the final episode of Luke Slaughter, which aired on June 15th, 1958. In it we learn that Slaughter was once a young lawyer, and his birth name was Lucien. With his commanding voice, Buffington could have been a radio leading man. His physical features — short, stocky, and balding — relegated him to character parts in film and TV.

On May 15, 1960 Less than two years after Luke Slaughter was cancelled, Sam Buffington committed suicide by asphyxiation. He was 28 years-old.
