Case 345
Who is guilty?
Exactly one suspect is guilty. The guilty suspect lies. Every innocent suspect tells the truth.
Maya: “The guilty person is either Owen or Iris.”
Noah: “Iris is guilty.”
Lena: “Noah is innocent.”
Owen: “The guilty person is one of Maya, Noah or Iris.”
Iris: “The guilty person is either Maya or Noah.”
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.
