if u r not smart enough u wont find all the evidence so it means u have to find the person who has fake alibi or none and that others suspects. by no alibi i mean someone who has told u they dont have alibi, NOT someone who clammed on u.
If you are trying this case over and over, it must be featured mystery? Unless you are talking about different cases? Hate to say it, but I am confused by the question! Might want to chat with someone directly in your agency.
If you are on featured mysteries, I will say just wait until you have more experience in the random cases and try again.
If you are talking random cases, reda is right.
Sounds like the person with "no alibi" whom you accused was a person who had clammed up about an alibi, rather than stating no alibi - a very different thing! You can't assume they have no valid alibi when they clam unless you are counting fakes and reals and can determine it through elimination.
Someone with hair and truly no alibi would be guilty, for sure.
Try the fake alibi people with the other suspects, as reda said. If two accuse one person, you're all set to accuse even if you are not sure about the alibi due to clamming.
Hope this isn't too confusing. I am trying to address too many possible situations, perhaps. And I didn't even ask, are you sure you got all the suspects on your list in the first place?
