Case 117
Who is guilty?
Exactly one suspect is guilty. The guilty suspect lies. Every innocent suspect tells the truth.
Sofia: “The guilty person is one of Sofia, Max or Cleo.”
Max: “Neither Sofia nor Ezra is guilty.”
Lily: “None of Max, Lily or Ezra is guilty.”
Ezra: “The guilty person is one of Max, Ezra or Cleo.”
Cleo: “None of Sofia, Lily or Cleo is guilty.”
Random case Solution: Cleo 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.
