Case 047
Who is guilty?
Exactly one suspect is guilty. The guilty suspect lies. Every innocent suspect tells the truth.
Isla: “The guilty person is one of Isla, Sam or Freya.”
Sam: “The guilty person is one of Freya, Cole or Eva.”
Freya: “Cole is guilty.”
Cole: “The guilty person is either Freya or Cole.”
Eva: “The guilty person is one of Sam, Freya or Cole.”
Random case Solution: Freya 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.
