Case 177
Who is guilty?
Exactly one suspect is guilty. The guilty suspect lies. Every innocent suspect tells the truth.
Maya: “None of Maya, Owen or Iris is guilty.”
Noah: “The guilty person is either Maya or Owen.”
Lena: “Owen is innocent.”
Owen: “The guilty person is one of Noah, Lena or Iris.”
Iris: “Neither Owen nor Iris is guilty.”
Random case Solution: Noah 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.
