Case 105
Who is guilty?
Exactly one suspect is guilty. The guilty suspect lies. Every innocent suspect tells the truth.
Maya: “None of Noah, Lena or Owen is guilty.”
Noah: “The guilty person is one of Noah, Owen or Iris.”
Lena: “Neither Noah nor Lena is guilty.”
Owen: “The guilty person is either Maya or Iris.”
Iris: “None of Maya, Owen or Iris is guilty.”
Random case Solution: Iris 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.
