Case 259
Who is guilty?
Exactly one suspect is guilty. The guilty suspect lies. Every innocent suspect tells the truth.
Ruby: “Neither Ruby nor Mila is guilty.”
Theo: “None of Theo, Mila or Finn is guilty.”
Mila: “None of Mila, Finn or Jade is guilty.”
Finn: “Theo is guilty.”
Jade: “The guilty person is one of Ruby, Theo or Finn.”
Random case Solution: Theo 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.
