Case 012
Who is guilty?
Exactly one suspect is guilty. The guilty suspect lies. Every innocent suspect tells the truth.
Chloe: “Neither Chloe nor Esme is guilty.”
Leo: “None of Leo, Esme or Nina is guilty.”
Esme: “Neither Esme nor Kai is guilty.”
Kai: “Neither Chloe nor Kai is guilty.”
Nina: “Neither Esme nor Nina 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.
