Case 231
Who is guilty?
Exactly one suspect is guilty. The guilty suspect lies. Every innocent suspect tells the truth.
Isla: “Cole is innocent.”
Sam: “Sam is innocent.”
Freya: “None of Sam, Freya or Cole is guilty.”
Cole: “Eva is guilty.”
Eva: “Neither Sam nor Eva is guilty.”
Random case Solution: Eva 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.
