Case 048
Who is guilty?
Exactly one suspect is guilty. The guilty suspect lies. Every innocent suspect tells the truth.
Ada: “Neither Ada nor Luke is guilty.”
Luke: “The guilty person is one of Ada, Luke or Ben.”
Mia: “Neither Mia nor Ben is guilty.”
Ben: “The guilty person is one of Ada, Luke or Skye.”
Skye: “Neither Ben nor Skye 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.
