Case 056
Who is guilty?
Exactly one suspect is guilty. The guilty suspect lies. Every innocent suspect tells the truth.
Ada: “Ben is innocent.”
Luke: “The guilty person is one of Ada, Luke or Skye.”
Mia: “Neither Luke nor Ben is guilty.”
Ben: “The guilty person is either Ada or Skye.”
Skye: “The guilty person is one of Ada, Luke or Ben.”
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.
