Case 152
Who is guilty?
Exactly one suspect is guilty. The guilty suspect lies. Every innocent suspect tells the truth.
Ada: “Mia is innocent.”
Luke: “The guilty person is either Ada or Mia.”
Mia: “Ada is innocent.”
Ben: “The guilty person is one of Ada, Luke or Mia.”
Skye: “The guilty person is one of Luke, Ben or Skye.”
Random case Solution: Luke 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.
