Case 237
Who is guilty?
Exactly one suspect is guilty. The guilty suspect lies. Every innocent suspect tells the truth.
Sofia: “Neither Sofia nor Cleo is guilty.”
Max: “The guilty person is one of Max, Lily or Cleo.”
Lily: “The guilty person is either Max or Ezra.”
Ezra: “Sofia is innocent.”
Cleo: “The guilty person is either Sofia or Lily.”
Random case Solution: Lily 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.
