Case 120
Who is guilty?
Exactly one suspect is guilty. The guilty suspect lies. Every innocent suspect tells the truth.
Ada: “Ada is innocent.”
Luke: “Skye is guilty.”
Mia: “None of Ada, Luke or Mia is guilty.”
Ben: “The guilty person is one of Ada, Mia or Skye.”
Skye: “None of Luke, Mia or Skye is guilty.”
Random case Solution: Skye 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.
