Case 250
Who is guilty?
Exactly one suspect is guilty. The guilty suspect lies. Every innocent suspect tells the truth.
Ava: “The guilty person is either Eli or Zoe.”
Eli: “The guilty person is either Miles or Zoe.”
Nora: “Neither Eli nor Miles is guilty.”
Miles: “Miles is innocent.”
Zoe: “None of Eli, Miles or Zoe is guilty.”
Random case Solution: Zoe 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.
