Case 028
Who is guilty?
Exactly one suspect is guilty. The guilty suspect lies. Every innocent suspect tells the truth.
Chloe: “Neither Esme nor Nina is guilty.”
Leo: “Esme is innocent.”
Esme: “The guilty person is one of Chloe, Leo or Kai.”
Kai: “Kai is innocent.”
Nina: “The guilty person is either Leo or Kai.”
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.
