Case 103
Who is guilty?
Exactly one suspect is guilty. The guilty suspect lies. Every innocent suspect tells the truth.
Isla: “Cole is guilty.”
Sam: “The guilty person is either Isla or Eva.”
Freya: “Isla is guilty.”
Cole: “The guilty person is one of Isla, Freya or Cole.”
Eva: “Neither Sam nor Freya is guilty.”
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.
