Case 275
Who is guilty?
Exactly one suspect is guilty. The guilty suspect lies. Every innocent suspect tells the truth.
Ruby: “The guilty person is one of Theo, Mila or Jade.”
Theo: “Neither Theo nor Finn is guilty.”
Mila: “The guilty person is either Finn or Jade.”
Finn: “The guilty person is one of Ruby, Theo or Mila.”
Jade: “The guilty person is either Mila or Jade.”
Random case Solution: Mila 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.
