Case 195
Who is guilty?
Exactly one suspect is guilty. The guilty suspect lies. Every innocent suspect tells the truth.
Ruby: “Ruby is innocent.”
Theo: “None of Theo, Finn or Jade is guilty.”
Mila: “Neither Ruby nor Jade is guilty.”
Finn: “Neither Mila nor Finn is guilty.”
Jade: “Neither Ruby nor Finn is guilty.”
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.
