John Stevenson owns a black car. The murderer owns a white car, so John Stevenson is not the murderer.
The suspect who has brown hair owns a blue car. The suspect who has a wife named Joyce has brown hair. The suspect who has a wife named Joyce is 5 feet tall. Therefore, one suspect has brown hair, owns a blue car, has a wife named Joyce, and is 5 feet tall. But Jim Fox has blond hair, Marty Davis is 6 feet tall, Brian Edison has a wife named Cathy, and John Stevenson owns a black car. Therefore, the only suspect who could be this suspect is Larry Martin. Since Larry Martin owns a blue car, he is not the murderer.

Since the murderer owns a white car and Marty Davis owns a white car, he is the murderer.
