Case 205
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 Max, Lily or Cleo.”
Max: “The guilty person is one of Sofia, Ezra or Cleo.”
Lily: “The guilty person is one of Sofia, Lily or Cleo.”
Ezra: “The guilty person is one of Sofia, Max or Lily.”
Cleo: “The guilty person is one of Sofia, Max or Ezra.”
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.
