Case 181
Who is guilty?
Exactly one suspect is guilty. The guilty suspect lies. Every innocent suspect tells the truth.
Sofia: “The guilty person is either Lily or Ezra.”
Max: “Neither Max nor Cleo is guilty.”
Lily: “The guilty person is either Ezra or Cleo.”
Ezra: “Cleo is guilty.”
Cleo: “None of Max, Lily or Cleo is guilty.”
Random case Solution: Ezra 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.
