Case 215
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 Freya, Cole or Eva.”
Sam: “The guilty person is either Isla or Sam.”
Freya: “Cole is innocent.”
Cole: “None of Freya, Cole or Eva is guilty.”
Eva: “The guilty person is either Isla or Freya.”
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.
