Case 364
The Empty Safe
A small office safe was found empty in the morning.
Rule: exactly one suspect is guilty. The guilty suspect lies. Every innocent suspect tells the truth.
Kendall
“Taylor is innocent.”
Taylor
“Neither Kendall nor Dakota is guilty.”
Noah
“Either Taylor or Morgan is guilty.”
Dakota
“Neither Kendall nor Taylor is guilty.”
Morgan
“Kendall and Taylor are both innocent.”
Who is guilty?
Solution: Noah
If Noah is guilty, Noah's statement is false and every other statement is true. Testing the other suspects creates at least one contradiction.
