Bob Davis has a wife named Mary. The suspect who was carrying a red umbrella has a wife named Mary. Therefore, Bob Davis was carrying a red umbrella. The murderer was carrying a purple umbrella, so Bob Davis is not the murderer.
The suspect who weighs 220 pounds was carrying a purple umbrella. The suspect who weighs 220 pounds has a wife named Sally. The suspect who has a wife named Sally is not the one who was wearing a black shirt. Therefore, one suspect weighs 220 pounds, was carrying a purple umbrella, has a wife named Sally, and is not the one who was wearing a black shirt. But Jim Graig weighs 210 pounds, Larry Edison was wearing a black shirt, David Fox has a wife named Joyce, and Bob Davis was carrying a red umbrella. Therefore, the only suspect who could be this suspect is Tom Smith. Since this suspect, Tom Smith, was carrying a purple umbrella and the murderer was carrying a purple umbrella, he is the murderer.
