Case 252
Who is guilty?
Exactly one suspect is guilty. The guilty suspect lies. Every innocent suspect tells the truth.
Chloe: “Nina is innocent.”
Leo: “None of Chloe, Leo or Esme is guilty.”
Esme: “The guilty person is one of Chloe, Leo or Kai.”
Kai: “The guilty person is one of Chloe, Esme or Nina.”
Nina: “Neither Chloe nor Esme is guilty.”
Random case Solution: Kai 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.
