Case 302
Who is guilty?
Exactly one suspect is guilty. The guilty suspect lies. Every innocent suspect tells the truth.
Amira: “The guilty person is either Jack or Tess.”
Jack: “None of Amira, Jack or Hugo is guilty.”
Tess: “The guilty person is either Jack or Mae.”
Hugo: “None of Amira, Hugo or Mae is guilty.”
Mae: “The guilty person is one of Amira, Jack or Hugo.”
Random case Solution: Jack is guilty. Testing each possible culprit leaves this as the only assignment where the culprit's statement is false and all four innocent statements are true.
