Case 197
Who is guilty?
Exactly one suspect is guilty. The guilty suspect lies. Every innocent suspect tells the truth.
Sofia: “The guilty person is either Sofia or Max.”
Max: “The guilty person is one of Lily, Ezra or Cleo.”
Lily: “Neither Sofia nor Lily is guilty.”
Ezra: “Neither Lily nor Cleo is guilty.”
Cleo: “Neither Lily nor Ezra is guilty.”
Random case Solution: Max 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.
