Case 150
Who is guilty?
Exactly one suspect is guilty. The guilty suspect lies. Every innocent suspect tells the truth.
Amira: “The guilty person is one of Tess, Hugo or Mae.”
Jack: “The guilty person is one of Amira, Jack or Hugo.”
Tess: “The guilty person is one of Amira, Jack or Tess.”
Hugo: “The guilty person is either Amira or Hugo.”
Mae: “Neither Jack nor Hugo is guilty.”
Random case Solution: Amira 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.
