Case 266
Who is guilty?
Exactly one suspect is guilty. The guilty suspect lies. Every innocent suspect tells the truth.
Ava: “Neither Ava nor Zoe is guilty.”
Eli: “Neither Nora nor Zoe is guilty.”
Nora: “The guilty person is either Ava or Zoe.”
Miles: “None of Eli, Nora or Zoe is guilty.”
Zoe: “The guilty person is one of Ava, Eli or Nora.”
Random case Solution: Ava 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.
