Case 228
Who is guilty?
Exactly one suspect is guilty. The guilty suspect lies. Every innocent suspect tells the truth.
Chloe: “Leo is guilty.”
Leo: “The guilty person is either Chloe or Nina.”
Esme: “The guilty person is either Chloe or Leo.”
Kai: “The guilty person is one of Leo, Esme or Nina.”
Nina: “Neither Chloe nor Kai is guilty.”
Random case Solution: Leo 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.
