Case 127
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 Cole.”
Sam: “Sam is innocent.”
Freya: “Neither Sam nor Freya is guilty.”
Cole: “The guilty person is either Isla or Eva.”
Eva: “Neither Isla nor Sam is guilty.”
Random case Solution: Cole 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.
