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.

very nice... it took me a while to sort out the last two peoples hair colors (and guiltiness), but i got it in the end.
What fun, found it a bit hard but a lot of fun
very challenging, it took me a while to realize 5'9" and 6'0" were 3 inches apart!!!
very hard but easy at the same time
hard..
Really tough...thought I'd never get it solved...but I did! Thanks!
Wow! Hardest one I've done so far!! I had to restart it at least 3 times! Mind boggling! I loved it though. A challenge is a great thing! Keep em coming!
Very good! Had to put it down and come back. Then I got it.
great thing about this puzzle is there were scarcely any redundant clues. looking forward for more puzzles from you.
I thought a person with blonde hair had darker hair than one who was bald.
I have found one redundant clue. I am thinking about submitting a correction.
I was waiting for a comment about hair color. That is one of the implicit clues. If you are bald, you have no hair color. Nonetheless, a legitimate question.

Very nice. Like others here I had to put it down a couple of times. My answer was identical to the solution, except I had the hair colours of Tim and Gus the other way around, ie, I had Tim with blonde hair and Gus with Red hair, so I got Gus as the guilty party.
Is this also correct?
Is this also correct?
Gus weighs 178 pounds. That weight would satisfy clue 1 about the guilty man. But in order to be guilty, Gus also would have had to been 32 years old, satisfying clue 4.
Thanks for that. I see know.. Very good clues... This is one hell of a good puzzle.
Cheers........
Cheers........
I loved it!!!! I had a really difficult time with it, and had to start it over several times. But it was well worth it.
I loved how one neded to go back to the clues to find out who was guilty! Excellent teaser, I had a really good time solving it.
Fantastic puzzle! Very creative use of clues with the added twist of finding the guilty party. I got it all right in the end!
great teaser! I still haven't finished it. This will be my 3rd time trying. Really tricky...
4th time's the charm! It seemed to make so much more sense today than it did yesterday. Good Job!
This was an awesome teaser! It took me quite some time and a couple tries to figure it out!

Well I dont know if it is just me or some one else saw this as well? The solution given just doesn't make sense. How can sam's and tim's height be 6 and 5.9 respectively when there has to be a difference of 3 inches between their heights!
Jan 04, 2009
oops! 6 - 5.9 is three :O..
This was my favorite logic puzzle ever! I had to put it down a few times and really didn't think I would solve it, considering how many times I got stuck. Was able to get it right in the end. Hard puzzle but very fun!
Winner4600 i know what your saying. I had same proble with time.

Fantastic! Sometimes 'bald' refers to someone with a discernible hair color, but not here. I like your no-frills style.
Something seems to be wrong with the coding on this puzzle's grid solver. I can work it out on paper just fine, but I figured I'd mention the problem in the comments just in case it's not just my computer screwing up.
I loved how all the clues worked together; definitely one of the best logic grid puzzles I've done! more of Sheerluck, please?
also not familiar with the imperial System (6.0 - 5.9 = 3 inches ) but beside that it is one of my favorites
