Case 180
Who is guilty?
Exactly one suspect is guilty. The guilty suspect lies. Every innocent suspect tells the truth.
Chloe: “Chloe is innocent.”
Leo: “Nina is guilty.”
Esme: “The guilty person is one of Chloe, Esme or Nina.”
Kai: “Neither Chloe nor Kai is guilty.”
Nina: “The guilty person is one of Leo, Esme or Kai.”
Random case Solution: Nina 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.
