Case 041
Who is guilty?
Exactly one suspect is guilty. The guilty suspect lies. Every innocent suspect tells the truth.
Maya: “The guilty person is one of Maya, Owen or Iris.”
Noah: “The guilty person is one of Maya, Noah or Iris.”
Lena: “None of Maya, Noah or Lena is guilty.”
Owen: “Owen is innocent.”
Iris: “None of Lena, 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.
