Case 122
Who is guilty?
Exactly one suspect is guilty. The guilty suspect lies. Every innocent suspect tells the truth.
Ava: “Eli is innocent.”
Eli: “The guilty person is one of Ava, Eli or Miles.”
Nora: “None of Ava, Nora or Zoe is guilty.”
Miles: “Ava is guilty.”
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.
