Case 151
Who is guilty?
Exactly one suspect is guilty. The guilty suspect lies. Every innocent suspect tells the truth.
Isla: “The guilty person is either Sam or Eva.”
Sam: “Freya is innocent.”
Freya: “The guilty person is one of Isla, Freya or Eva.”
Cole: “The guilty person is either Isla or Cole.”
Eva: “Eva is innocent.”
Random case Solution: Isla 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.
