Case 014
Who is guilty?
Exactly one suspect is guilty. The guilty suspect lies. Every innocent suspect tells the truth.
Amira: “Neither Tess nor Mae is guilty.”
Jack: “Neither Jack nor Tess is guilty.”
Tess: “The guilty person is either Amira or Hugo.”
Hugo: “None of Jack, Hugo or Mae is guilty.”
Mae: “None of Amira, Jack or Mae is guilty.”
Random case Solution: Hugo 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.
