Case 053
Who is guilty?
Exactly one suspect is guilty. The guilty suspect lies. Every innocent suspect tells the truth.
Sofia: “Sofia is innocent.”
Max: “The guilty person is one of Sofia, Ezra or Cleo.”
Lily: “Neither Ezra nor Cleo is guilty.”
Ezra: “Neither Max nor Lily is guilty.”
Cleo: “The guilty person is one of Sofia, Max or Lily.”
Random case Solution: Sofia 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.
