Case 305
Who is guilty?
Exactly one suspect is guilty. The guilty suspect lies. Every innocent suspect tells the truth.
Maya: “Iris is innocent.”
Noah: “Noah is innocent.”
Lena: “Noah is guilty.”
Owen: “The guilty person is either Maya or Noah.”
Iris: “The guilty person is one of Noah, Lena or Owen.”
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.
