Case 325
Who is guilty?
Exactly one suspect is guilty. The guilty suspect lies. Every innocent suspect tells the truth.
Sofia: “The guilty person is either Max or Lily.”
Max: “Ezra is innocent.”
Lily: “The guilty person is one of Sofia, Max or Ezra.”
Ezra: “None of Sofia, Max or Cleo is guilty.”
Cleo: “Neither Max nor Ezra is guilty.”
Random case Solution: Lily 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.
