Case 128
Who is guilty?
Exactly one suspect is guilty. The guilty suspect lies. Every innocent suspect tells the truth.
Ada: “None of Ada, Ben or Skye is guilty.”
Luke: “Skye is innocent.”
Mia: “None of Luke, Ben or Skye is guilty.”
Ben: “None of Luke, Mia or Skye is guilty.”
Skye: “None of Luke, Mia or Ben is guilty.”
Random case Solution: Ada 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.
