Case 024
Who is guilty?
Exactly one suspect is guilty. The guilty suspect lies. Every innocent suspect tells the truth.
Ada: “Neither Ada nor Mia is guilty.”
Luke: “None of Mia, Ben or Skye is guilty.”
Mia: “The guilty person is one of Ada, Ben or Skye.”
Ben: “Neither Ben nor Skye is guilty.”
Skye: “Neither Luke nor Mia 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.
