Case 298
Who is guilty?
Exactly one suspect is guilty. The guilty suspect lies. Every innocent suspect tells the truth.
Ava: “Neither Nora nor Zoe is guilty.”
Eli: “The guilty person is one of Nora, Miles or Zoe.”
Nora: “The guilty person is one of Ava, Nora or Miles.”
Miles: “The guilty person is one of Ava, Eli or Nora.”
Zoe: “The guilty person is one of Eli, Miles or Zoe.”
Random case Solution: Miles 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.
