Case 193
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 Lena, Owen or Iris.”
Noah: “Noah is innocent.”
Lena: “The guilty person is one of Maya, Lena or Owen.”
Owen: “The guilty person is either Noah or Lena.”
Iris: “Owen 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.
