Case 289
Who is guilty?
Exactly one suspect is guilty. The guilty suspect lies. Every innocent suspect tells the truth.
Maya: “Noah is guilty.”
Noah: “Neither Lena nor Iris is guilty.”
Lena: “Iris is innocent.”
Owen: “The guilty person is either Maya or Lena.”
Iris: “Neither Lena nor Owen is guilty.”
Random case Solution: Maya 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.
