Case 076
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.
Noah
“Reese is innocent.”
Reese
“Neither Parker nor Lane is guilty.”
Parker
“Neither Noah nor Reese is guilty.”
Lane
“Noah is innocent.”
Kai
“Either Reese or Lane is guilty.”
Who is guilty?
Solution: Kai
If Kai is guilty, Kai's statement is false and every other statement is true. Testing the other suspects creates at least one contradiction.
