Case 329
Who is guilty?
Exactly one suspect is guilty. The guilty suspect lies. Every innocent suspect tells the truth.
Maya: “Neither Maya nor Iris is guilty.”
Noah: “Owen is guilty.”
Lena: “Iris is innocent.”
Owen: “None of Noah, Owen or Iris is guilty.”
Iris: “Neither Noah nor Lena is guilty.”
Random case Solution: Owen 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.
