Case 097
Who is guilty?
Exactly one suspect is guilty. The guilty suspect lies. Every innocent suspect tells the truth.
Maya: “Neither Maya nor Owen is guilty.”
Noah: “None of Maya, Noah or Owen is guilty.”
Lena: “None of Maya, Lena or Iris is guilty.”
Owen: “Neither Maya nor Lena is guilty.”
Iris: “The guilty person is one of Noah, Lena or Iris.”
Random case Solution: Noah 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.
