Answer
First, fill in as much of the grid as possible, while ignoring the clues about the guilty man. Then, use those clues to fill in the rest of the grid. Given that the grid has been correctly filled, the following conclusions can be drawn.A) From clues 1 and 4, we know that the guilty man is one of the following: 6'0" and 32, 6'0" and 190, 6'0" and Tim, 178 and 32, 178 and Tim, Ben and 32, Ben and 190.
B) From clue 6 and since Ben is the youngest, Ben can be eliminated. Since Ben weighs 190, 190 can also be eliminated. This leaves the following combinations: 6'0" and 32, 6'0" and Tim, 178 and 32, 178 and Tim.
C) From clue 6 and since the lightest man is also 32, 32 can be eliminated. This leaves: 6'0" and Tim, 178 and Tim.
D) Both of the remaining pairs involve Tim, so Tim is the guilty man.
E) From clue 7 and since Tim is neither the heaviest nor the tallest, he must be the oldest, or 46.
F) From clue 11, Tim can not have blonde hair.
Ben, 29 years, 190 pounds, 6'4", brown
Gus, 42 years, 178 pounds, 6'3", blonde
Ron, 37 years, 216 pounds, 5'8", bald
Sam, 32 years, 166 pounds, 5'9", black
Tim, 46 years, 201 pounds, 6'0", red, guilty
Another case solved by sheer luck.
