Case 087
Who is guilty?
Exactly one suspect is guilty. The guilty suspect lies. Every innocent suspect tells the truth.
Isla: “None of Freya, Cole or Eva is guilty.”
Sam: “The guilty person is either Freya or Eva.”
Freya: “Freya is innocent.”
Cole: “None of Isla, Freya or Cole is guilty.”
Eva: “Sam is guilty.”
Random case Solution: Sam 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.
