Case 363
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 Ruby, Mila or Jade.”
Theo: “The guilty person is either Mila or Jade.”
Mila: “None of Ruby, Theo or Mila is guilty.”
Finn: “Neither Theo nor Mila is guilty.”
Jade: “The guilty person is either Ruby or Theo.”
Random case Solution: Jade 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.
