Case 178
Who is guilty?
Exactly one suspect is guilty. The guilty suspect lies. Every innocent suspect tells the truth.
Ava: “None of Eli, Nora or Miles is guilty.”
Eli: “The guilty person is one of Ava, Miles or Zoe.”
Nora: “The guilty person is one of Nora, Miles or Zoe.”
Miles: “The guilty person is either Ava or Zoe.”
Zoe: “The guilty person is either Nora or Miles.”
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.
